    2014-12-01

    Full Text Available Crop straw gasification technologies are the most promising biomass gasification technologies and have great potential to be further developed in China. However, the commercialization development of gasification technology in China is slow. In this paper, the technical reliability and practicability of crop straw gasification technologies, the economic feasibility of gas supply stations, the economic feasibility of crop straw gasification equipment manufacture enterprises and the social acceptability of crop straw gasification technologies are analyzed. The results show that presently both the atmospheric oxidation gasification technology and the carbonization pyrolysis gasification technology in China are mature and practical, and can provide fuel gas for households. However, there are still a series of problems associated with these technologies that need to be solved for the commercialization development, such as the high tar and CO content of the fuel gas. The economic feasibility of the gas supply stations is different in China. Parts of gas supply stations are unprofitable due to high initial investment, the low fuel gas price and the small numbers of consumers. In addition, the commercialization development of crop straw gasification equipment manufacture enterprises is hindered for the low market demand for gasification equipment which is related to the fund support from the government. The acceptance of the crop straw gasification technologies from both the government and the farmers in China may be a driving force of further commercialization development of the gasification technologies. Then, the crop straw gasification technologies in China have reached at the stage of pre-commercialization. At this stage, the gasification technologies are basically mature and have met many requirements of commercialization, however, some incentives are needed to encourage their further development.

    Yang, Faxian

    The problem of this study was to develop a strategy for integrating technology education concepts within the Chinese mathematics and science curricula. The researcher used a case study as the basic methodology. It included three methods for collecting data: literature review, field study in junior and senior secondary schools in America and China, and interviews with experienced educators who were familiar with the status of technology education programs in the selected countries. The data came from the following areas: Japan, Taiwan, the United Kingdom, China, and five states in the United States: Illinois, Iowa, Maryland, Massachusetts, and New York. The researcher summarized each state and country's educational data, identified the advantages and disadvantages of their current technology education program, and identified the major concepts within each program. The process determined that identified concepts would be readily acceptable into the current Chinese educational system. Modernization of, industry, agriculture, science and technology, and defense have been recent objectives of the Chinese government. Therefore, Chinese understanding of technology, or technology education, became important for the country. However, traditional thought and culture curb the implementation of technology education within China's current education system. The proposed solution was to integrate technology education concepts into China's mathematics and science curricula. The purpose of the integration was to put new thoughts and methods into the current educational structure. It was concluded that the proposed model and interventions would allow Chinese educators to carry out the integration into China's education system.

    In the past three decades, China has become a major contributor to science and technology. China now employs an increasingly large labor force of scientists and engineers at relatively high earnings and produces more science and engineering degrees than the United States at all levels, particularly bachelor's. China's research and development expenditure has been rising. Research output in China has been sharply increasing since 2002, making China the second largest producer of scientific papers after the United States. The quality of research by Chinese scientists has also been improving steadily. However, China's rise in science also faces serious difficulties, partly attributable to its rigid, top-down administrative system, with allegations of scientific misconduct trending upward.

    Full Text Available Open burning of straw in China has degraded agricultural environments and has become a contributor to air pollution. Development of efficient straw-reuse technologies not only can yield economic benefits but also can protect the environment and can provide greater benefit to society. Thus, the overall benefits of straw-reuse technologies must be considered when making regional development planning and enterprise technology decisions. In addition, agricultural areas in China cross several climatic zones and have different weather characteristics and cultural conditions. In the present study, we assessed five types of straw-reuse technologies (straw-biogas production, -briquetting, -based power generation, -gasification, and -bioethanol production, using emergy analysis, in northeast China. Within each type, five individual cases were investigated, and the highest-performing cases were used for comparison across technologies. Emergy indices for comprehensive benefits for each category, namely, EYR, ELR, and ESI were calculated. Calculated indices suggest that straw-briquetting and -biogas production are the most beneficial technologies in terms of economy, environmental impact, and sustainability compared to straw-based power generation, -gasification, and -bioethanol production technologies. These two technologies can thus be considered the most suitable for straw reuse in China.

    Modern dentistry and dental education in China were first introduced from abroad by Dr. Lindsay in 1907. However, advancements in the field of dental laboratory technology did not occur to the same degree in specialties such as prosthodontics and orthodontics. Since the 1990s, orders from abroad demanding dental appliances surged as the image of China as the "world's factory" strengthened. The assembly line model, in which technicians work like simple procedure workers, was rapidly applied to denture production, while the traditional education system and apprenticeship systems demonstrated little progress in these years. The lack of advancement in dental laboratory technology education caused insufficient development in China's dental technology industry. In order to alter the situation, a four-year dental laboratory technology undergraduate educational program was established in 2005 by West China School of Stomatology, Sichuan University (WCSS, SCU). This program was based on SCU's undergraduate education and WCSS's junior college education systems. The program introduced scientific methods in relevant subjects into laboratory technicians' training and made many improvements in the availability of trained faculty, textbooks, laboratory facilities, and curriculum.

    Acheulian tools with their associated level of cognizance heralded a major threshold in the evolution of hominin technology, culture and behavior. Thus, unraveling occurrence ages of Acheulian technology across different regions worldwide constitutes a key aspect of understanding the archeology of early human evolution. Here we present a magneto-cyclochronology for the Acheulian assemblage from Sanmenxia Basin, Loess Plateau, North China. Our results place a sequence of stable normal and reversed paleomagnetic polarities within a regional lithostratigraphic context. The Acheulian assemblage is dated to be older than the Matuyama-Brunhes boundary at 0.78 Ma, and is found in strata that are probably equivalent to a weak paleosol subunit within loess layer L9 in the Chinese loess-paleosol sequence, which corresponds to marine isotope stage (MIS) 23, a relatively subdued interglacial period with age range of ∼0.89-0.92 Ma. This age of ∼0.9 Ma implies that Acheulian stone tools were unambiguously present in North China during the Early Pleistocene. It distinctly enlarges the geographic distribution of Acheulian technology and brings its occurrence in North China back into the Early Pleistocene, which is contemporaneous with its first emergence in Europe. Combined with other archeological records, the larger area over which Acheulian technology existed in East Asia during the terminal Early Pleistocene has important implications for understanding early human occupation of North China.

    Biophysics has been either an independent discipline or an element of another discipline in the United States, but it has always been recognized as a stand-alone discipline in the People's Republic of China (PRC) since 1949. To inquire into this apparent divergence, this paper investigates the formational history of biophysics in China by examining the early institutional history of one of the best-known and prestigious science and technology universities in the PRC, the University of Science and Technology of China (USTC). By showing how the university and its biophysics program co-evolved with national priorities from the school's founding in 1958 to the eve of the Cultural Revolution in 1966, the purpose of this paper is to assess the development of a scientific discipline in the context of national demands and institutional politics. Specific materials for analysis include the school's admission policies, curricula, students' dissertations, and research program. To further contextualize the institutional setting of Chinese biophysics, this paper begins with a general history of proto-biophysical institutions in China during the Nationalist-Communist transitional years. This paper could be of interest to historians wanting to know more about the origin of the biophysics profession in China, and in particular how research areas that constitute biophysics changed in tandem with socio-political contingencies.

    This paper reviews the experience of women workers in China while the country's economy is changing into a globalized, technologically advanced one. New computer-based technology is increasingly acknowledged as a powerful and pervasive force that can shape or, at least in many ways, affect employment. It is hailed for opening up fresh employment opportunities and reducing the physical stress involved in work. However, the possibilities of redundancies or intensification of workload also exist. By focusing on changes in women's work, the article reveals the contradictions inherent in following a development path based on ever-higher levels of technology in the context of an intensive mode of production, to which productivity is the core value. The economy is bolstered and some workers gain employment in expanding industries. However, workers, who lack access to training and who are reliant on the dwindling state support for their reproductive responsibilities, are marginalized and seek employment in the growing informal economy.

Data at city and county level have been interpreted using a hierarchical system of indices, which are then ranked according to severity. Zonation maps will be presented for debris flows, landslide and rockfall hazards, flood risk in mainland China, and for soil erosion processes in the Yellow River basin. The worst debris flow hazards are to be found in southwest China as the land begins to become mountainous. Just over 20% of the land area is at high or very high risk of landslide and rockfall hazards, especially Yunnan, Sichuan, Gansu and Shannxi provinces. Flood risk is concentrated towards the eastern part of China, where the major rivers meet the sea. The paper will also consider data on technological disasters in China from 1900 to 2010, using data supplied by CRED. In terms of fatalities, industrial accidents appear to be dominated by explosion events. However, gas leaks have affected the largest number of people. Transport accidents are ranked in terms of fatalities as follows: water - road - rail - air. Fire is a major cause of loss of life, whereas chemical spills and poisoning seem to lead to fewer deaths.

    2017-01-01

    Full Text Available Carbon capture, utilization, and storage (CCUS is a gas injection technology that enables the storage of CO2 underground. The aims are twofold, on one hand to reduce the emissions of CO2 into the atmosphere and on the other hand to increase oil/gas/heat recovery. Different types of CCUS technologies and related engineering projects have a long history of research and operation in the USA. However, in China they have a short development period ca. 10 years. Unlike CO2 capture and CO2-EOR technologies that are already operating on a commercial scale in China, research into other CCUS technologies is still in its infancy or at the pilot-scale. This paper first reviews the status and development of the different types of CCUS technologies and related engineering projects worldwide. Then it focuses on their developments in China in the last decade. The main research projects, international cooperation, and pilot-scale engineering projects in China are summarized and compared. Finally, the paper examines the challenges and prospects to be experienced through the industrialization of CCUS engineering projects in China. It can be concluded that the CCUS technologies have still large potential in China. It can only be unlocked by overcoming the technical and social challenges.

  5. Origin of Mobile Cellular Network Technologies and Markets in Germany and China

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    The inventive foundation of mobile cellular technologies was laid about 100 years ago. Wireless voice service was Bundespost in the late 1950s and the first analogue cellular network called C-Netz emerged in the mid-1980s. In China, the first mobile cellular networks called TACS-A and TACS-B were installed by Ministry of Post and Telecommunication in the late 1980s. While describing the events in Germany and China, this paper concentrates on discussing the related technologies and their impacts in the marketplace. A comparison summarises some important findings. Japan and Europe's Nordic countries were the first nations to commercialise the I st generation analogous cellular technologies. There existed A-and B-Network in Germany and China, but the network nature of them is quite different. The market development in Germany and China was similar. The enlarged network capacity accommodated gradually more subscribers and prices related to the cellular services fell continuously. However, China's fee system was more complicated and has adopted the RPP regime, while Germany has been using the CPP billing. The article concludes that implications such as the relationship between science and technology, time lag between scientific discovery and technological applications and technology spillover from military to civilian area are the economic lessons learnt from the story of cellular origin.

    The German Postal Reform Ⅰ in 1989 introduced competition in the mobile cellular market. German cellular operators, DeTeMobil, Mannesmann, E-Plus and VIAG Interkom, built DI-, D2-, El- and E2-Netze based on GSM standards made in Europe. China Unicom was created in 1994 and China Telecom was separated from MPT in 1995. China Telecom and China Unicorn competed in a duopoly from the mid-1990s onwards and the cellular services provided by them also rely on GSM standards. China Telecom additionally deployed XLT technology (PHS) from the late 1990s onwards. While DeTeMobil and Mannesmarm conquered approximately 80%-90% of the market throughout the 1990s and were the two dominant market players in Germany, China's cellular market was mainly controlled by China Mobile. In Germany, prices related to cellular technology continued the downwards trend as a major result of the process of deregulation, liberalisation and competition. In China, price wars bad led to significant price reductions in the cellular market. Although network operators in both countries strived to deliver differentiated cellular Services, the two national markets in the 1990s were visibly shaped by product homogeneity.

  11. From technology transfer to local manufacturing: China's emergence in the global wind power industry

    Science.gov (United States)

    Lewis, Joanna Ingram

    This dissertation examines the development of China's large wind turbine industry, including the players, the status of the technology, and the strategies used to develop turbines for the Chinese market. The primary goals of this research project are to identify the models of international technology transfer that have been used among firms in China's wind power industry; examine to what extent these technology transfers have contributed to China's ability to locally manufacture large wind turbine technology; and evaluate China's ability to become a major player in the global wind industry. China is a particularly important place to study the opportunities for and dynamics of clean energy development due to its role in global energy consumption. China is the largest coal consuming and producing nation in the world, and consequently the second largest national emitter of carbon dioxide after only the United States. Energy consumption and carbon emissions are growing rapidly, and China is expected to surpass the US and become the largest energy consuming nation and carbon dioxide emitter in coming decades. The central finding of this dissertation is that even though each firm involved in the large wind turbine manufacturing industry in China has followed a very different pathway of technology procurement for the Chinese market, all of the firms are increasing the utilization of locally-manufactured components, and many are doing so without transferring turbine technology or the associated intellectual property. Only one fully Chinese-owned firm, Goldwind, has succeeded in developing a commercially available large wind turbine for the Chinese market. No Chinese firms or foreign firms are manufacturing turbines in China for export overseas, though many have stated plans to do so. There already exists a possible niche market for the smaller turbines that are currently being made in China, particularly in less developed countries that are looking for less expensive

    2015-07-01

    This paper investigates the role of green innovations aimed at reducing carbon dioxide emissions as a factor that compensates for growth and population effects. It has been shown from tests that the positive effect of green innovations on carbon emissions exists within a STIRPAT framework from a local perspective. The panel data is derived from China Statistical Yearbook and China Intellectual Property Office covered from 1999 to 2013. In addition,the static panel model was run to estimate the diversity among three typical regions of China. The main result shows that the green technology change has not played a dominant role yet in promoting environmental protection, while a scale effect (Affluence and Population)still prevails, although green patents show positive influences on the CO2 emission reduction inthe whole country as well as the East and West regions, except the Central region. Moreover, it turns out that the classical EKC hypothesis does stand in China, referring to the three regions with the inverted "U" shape. The analysis gives suggestions to the policy makers, which would support enlarging the investment scale on green patents and encourage international corporation with environmental related innovations.

  19. Scientific and Technological Innovation Is an Important Approach to Ensuring China's Oil Security

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    With the rapid and continual growth of national economy, the gap between oil demand and supply keeps widening in China, therefore China will increasingly depend on imported oil. However, the world's oil and gas resources are unevenly distributed; global world's oil prices remain high; and over 70 percent of China's imported oil has to be shipped through the Malacca Strait. There are various ways to ensure China's oil security today, and the practical and feasible strategic option is to increase the discovery and production of domestic oil, raise energy efficiency and develop petroleum substitutes. Scientific and technological innovation is crucial both in new oil reserves discovery and production,energy conservation, and in the development of petroleum substitutes, establishment of a strategic oil reserve system and for environment protection. This indicates that China should take effective measures in investment strategy, fiscal policies, financing instruments, intellectual property protection, fostering talents and professionals, so as to establish its own scientific and technological innovation system in the petroleum industry and be better able to ensure oil security.

  20. New technologies reduce greenhouse gas emissions from nitrogenous fertilizer in China.

    Synthetic nitrogen (N) fertilizer has played a key role in enhancing food production and keeping half of the world's population adequately fed. However, decades of N fertilizer overuse in many parts of the world have contributed to soil, water, and air pollution; reducing excessive N losses and emissions is a central environmental challenge in the 21st century. China's participation is essential to global efforts in reducing N-related greenhouse gas (GHG) emissions because China is the largest producer and consumer of fertilizer N. To evaluate the impact of China's use of N fertilizer, we quantify the carbon footprint of China's N fertilizer production and consumption chain using life cycle analysis. For every ton of N fertilizer manufactured and used, 13.5 tons of CO2-equivalent (eq) (t CO2-eq) is emitted, compared with 9.7 t CO2-eq in Europe. Emissions in China tripled from 1980 [131 terrogram (Tg) of CO2-eq (Tg CO2-eq)] to 2010 (452 Tg CO2-eq). N fertilizer-related emissions constitute about 7% of GHG emissions from the entire Chinese economy and exceed soil carbon gain resulting from N fertilizer use by several-fold. We identified potential emission reductions by comparing prevailing technologies and management practices in China with more advanced options worldwide. Mitigation opportunities include improving methane recovery during coal mining, enhancing energy efficiency in fertilizer manufacture, and minimizing N overuse in field-level crop production. We find that use of advanced technologies could cut N fertilizer-related emissions by 20-63%, amounting to 102-357 Tg CO2-eq annually. Such reduction would decrease China's total GHG emissions by 2-6%, which is significant on a global scale.

    Supply chain collaboration has received increasing attention from scholars and practitioners in recent years. However, our understanding of how enterprise information technology facilitates supply chain collaboration is still very limited, especially with regard to Chinese enterprise ownerships such as state-owned firms, joint-venture firms and local village-owned firms. This paper extends the theory established in enterprise information technology (IT) and supply chain collaboration literature and relates it with coordination in China-linked supply chain. Drawing upon an empirical study from 177 Chinese companies, we provide three major findings: (i) uncovered the importance of leveraging enterprise IT through supply chain collaboration; (ii) identified the relationship between enterprise ownership and enterprise technology use and supply chain collaboration in China-linked supply chain and (iii) illustrated effects of supply chain collaborative activities on operational and market performance.

    Among the various types of renewable energy, solar photovoltaic has elicited the most attention because of its low pollution, abundant reserve, and endless supply. Solar photovoltaic technology generates both positive and negative effects on the environment. The environmental loss of 0.00666 yuan/kWh from solar photovoltaic technology is lower than that from coal-fired power generation (0.05216 yuan/kWh). The negative effects of solar photovoltaic system production include wastewater and waste gas pollutions, the representatives of which contain fluorine, chromium with wastewater and hydrogen fluoride, and silicon tetrachloride gas. Solar panels are also a source of light pollution. Improper disposal of solar cells that have reached the end of their service life harms the environment through the stench they produce and the damage they cause to the soil. So, the positive and negative effects of green energy photovoltaic power generation technology on the environment should be considered.

    Ethics education has become essential in modern engineering. Ethics education in engineering has been increasingly implemented worldwide. It can improve ethical behaviors in technology and engineering design under the guidance of the philosophy of technology. Hence, this study aims to compare China-US engineering ethics education in Sino-Western philosophies of technology by using literature studies, online surveys, observational researches, textual analyses, and comparative methods. In my original theoretical framework and model of input and output for education, six primary variables emerge in the pedagogy: disciplinary statuses, educational goals, instructional contents, didactic models, teaching methods, and edificatory effects. I focus on the similarities and differences of engineering ethics educations between China and the U.S. in Chinese and Western philosophies of technology. In the field of engineering, the U.S. tends toward applied ethics training, whereas China inclines toward practical moral education. The U.S. is the leader, particularly in the amount of money invested and engineering results. China has quickened its pace, focusing specifically on engineering labor input and output. Engineering ethics is a multiplayer game effected at various levels among (a) lower level technicians and engineers, engineering associations, and stockholders; (b) middle ranking engineering ethics education, the ministry of education, the academy of engineering, and the philosophy of technology; and (c) top national and international technological policies. I propose that professional engineering ethics education can play many important roles in reforming engineering social responsibility by international cooperation in societies that are becoming increasingly reliant on engineered devices and systems. Significantly, my proposals contribute to improving engineering ethics education and better-solving engineering ethics issues, thereby maximizing engineering

    In China, the philosophy of science and technology (PST) is derived from "Dialectics of Nature" (DN), which is based on Engels' unfinished book Dialektik der Natur. DN as a political ideology provides political guidance for scientists and engineers. Therefore, since 1981, "Introduction to Dialectics of Nature" (IDN) has been an obligatory course for master's degree students who study natural science or technology. In 1987, DN was renamed PST by the Chinese government in order to communicate and do research. The IDN teachers constitute most of the scholars who research PST. Nowadays, in China, PST includes philosophy of nature, philosophy of science, philosophy of technology, sociology of science, sociology of technology, "science, technology and society," history of science, history of technology, management of science, and management of technology due to having too many IDN teachers. In fact, it is neither a branch of philosophy, nor a subject. The number of the IDN teachers has been increasing since 1981, which makes PST a miscellaneous collection of many branches or subjects. Finally, PST is facing two new challenges: the reduction of IDN and academic corruption.

We performed a quantitative literature analysis in three major Chinese academic databases and one English language database using Chinese search terms equivalent to the concept of usability. Six hundred forty-seven publications were selected for analysis. We found that in China the literature on usability in the field of information technology began in 1994 and increased thereafter. The usability definitions from ISO 9241-11:1998 and Nielsen (1993) have been widely recognized and cited. Authors who have published several publications are rare. Fourteen journals have a publishing rate over 1%. Only nine publications about HIT were identified. China's usability research started relatively late. There is a lack of organized research teams and dedicated usability journals. High-impact theoretical studies are scarce. On the application side, no original and systematic research frameworks have been developed. The understanding and definition of usability is not well synchronized with international norms. Besides, usability research in HIT is rare. More human and material resources need to be invested in China's usability research, particularly in HIT.

    With its enormous social and economical development, China is now experiencing a rapid increase in solid wastes generation and growing pressure for solid wastes management. Today solid wastes in China are mainly managed by a combination of landfill, incineration, and composting. Within different possible treatment routes, thermal plasma technology (TPT) offers the advantages of efficiently gasifying the organic contents of solid wastes into syngas that can be used for heat and power generation, and vitrifying the inorganics simultaneously into glassy slag with very low leachabilities. This process makes it feasible for near-zero emission into the environment while making use of all the useful components. Encouraged by the industrial operations of solid wastes treatment plants using TPT in some countries, several plasma demonstration projects have already been undertaken in China. This paper provides a preliminary overview of the current laboratory researches and industrial developments status of TPT for the treatment of solid wastes in China and analyzes the existing challenges. Furthermore, the future prospects for TPT in China are also discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Tang, Tian

    The following dissertation explains how technological change of wind power, in terms of cost reduction and performance improvement, is achieved in China and the US through energy policies, technological learning, and collaboration. The objective of this dissertation is to understand how energy policies affect key actors in the power sector to promote renewable energy and achieve cost reductions for climate change mitigation in different institutional arrangements. The dissertation consists of three essays. The first essay examines the learning processes and technological change of wind power in China. I integrate collaboration and technological learning theories to model how wind technologies are acquired and diffused among various wind project participants in China through the Clean Development Mechanism (CDM)--an international carbon trade program, and empirically test whether different learning channels lead to cost reduction of wind power. Using pooled cross-sectional data of Chinese CDM wind projects and spatial econometric models, I find that a wind project developer's previous experience (learning-by-doing) and industrywide wind project experience (spillover effect) significantly reduce the costs of wind power. The spillover effect provides justification for subsidizing users of wind technologies so as to offset wind farm investors' incentive to free-ride on knowledge spillovers from other wind energy investors. The CDM has played such a role in China. Most importantly, this essay provides the first empirical evidence of "learning-by-interacting": CDM also drives wind power cost reduction and performance improvement by facilitating technology transfer through collaboration between foreign turbine manufacturers and local wind farm developers. The second essay extends this learning framework to the US wind power sector, where I examine how state energy policies, restructuring of the electricity market, and learning among actors in wind industry lead to

    From the use of renewable resources and environmental protection viewpoints, recycling of waste printed circuit boards (PCBs) receives wide concerns as the amounts of scrap PCBs increases dramatically. However, treatment for waste PCBs is a challenge due to the fact that PCBs are diverse and complex in terms of materials and components makeup as well as the original equipment's manufacturing processes. Recycle technology for waste PCBs in China is still immature. Previous studies focused on metals recovery, but resource utilization for nonmetals and further separation of the mixed metals are relatively fewer. Therefore, it is urgent to develop a proper recycle technology for waste PCBs. In this paper, current status of waste PCBs treatment in China was introduced, and several recycle technologies were analyzed. Some advices against the existing problems during recycling process were presented. Based on circular economy concept in China and complete recycling and resource utilization for all materials, a new environmental-friendly integrated recycling process with no pollution and high efficiency for waste PCBs was provided and discussed in detail.

    In the article the author looks back the hard development course and great progress in earth quake science and technology in China during the last near a half of century and expounds the following 3 aspects: (1) The strong desire of the whole society to mitigate seismic disasters and reduce the effect of earthquakes on social-economic live is a great driving force to push forward the development of earthquake science and technology in China; (2) To better ensure people' s life and property, sustainable economic development, and social stability is an essential purpose to drive the development of earthquake science and technology in China; and (3) To insist on the dialectical connection of setup of technical system for seismic monitoring with the scientific research of earthquakes and to better handle the relation between crucial task, current scientif ic level, and the feasibility are the important principles to advance the earthquake science and technology in China. Some success and many setbacks in earthquake disaster mitigation consistently enrich our knowledge regarding the complexity of the conditions for earthquake occurrence and the process of earthquake preparation, promote the reconstruction and modernization of technical system for earthquake monitoring, and deepen the scientific research of earthquakes. During the last 5 years, the improvement and modernization of technical system for earthquake monitoring have clearly provided the technical support to study and practice of earthquake prediction and pre caution, give prominence to key problems and broaden the field of scientific research of earth quakes. These have enabled us to get some new recognition of the conditions for earthquake oc currence and process of earthquake preparation, characteristics of seismic disaster, and mecha nism for earthquake generation in China's continent. The progress we have made not only en courages us to enhance the effectiveness of earthquake disaster mitigation, but also

    Full Text Available In this study, we bridge an important gap in the literature by comparing the extent to which external technology spillovers, as indicated by foreign direct investment (FDI, and internal technology spillovers, as indicated by university-institute-industry cooperation (UIC, influence innovation efficiency in China. We divide the innovation process into two sequential stages, namely the knowledge creation and technology commercialization stages, and employ a network data envelopment analysis approach to measure innovation efficiency at each stage. The spatial analysis of the distribution of knowledge creation efficiency and technology commercialization efficiency reveals the heterogeneity of innovation efficiency at the provincial level. Then, a panel data regression is used to analyze the effect of FDI and UIC on innovation efficiency at each stage, using data from 2009 to 2015 for 30 provinces in China. By comparing FDI with UIC, we find that FDI has a higher coefficient and stronger significance level at the knowledge creation stage, while only industry-institute linkages exhibit a stronger association with innovation efficiency at the technology commercialization stage.

    Parker, Rachel

    This dissertation is an analysis of the ways in which Chinese central government science, technology, and innovation (STI) policies are shaping the country's development trajectory in the 21st century. The study investigates the relationship between STI policy and development in China in order to understand whether the two are in congruence as the Country continues the rapid growth trajectory it has experienced over recent years. This work uses nanotechnology as a case study to analyze whether efforts by the Chinese central government have been successful in elevating the research and development output of the emerging economy. 72 semi-structured interviews were conducted in China, Hong Kong, Taiwan, and the United States and additional data was collected and analyzed in order to understand the impact of state-led nanotechnology policy. China (among other emerging economies) is convinced that it must strengthen its capabilities across the entire value chain rather than focusing on its manufacturing sector alone. The country's overarching goal is to become an "innovation-oriented" society by the year 2020. The importance placed on innovation in China's approach to growth and development---as compared with the strategy of the U.S. through its National Nanotechnology Initiative is of central concern to this study. In China, as in the U.S., nanotechnology is being funded largely through government sources, with much of the funding being directed toward basic research despite the fact that both countries have placed significant hope on the commercialization potential of the emerging technology area. This project examines the role played by government policies in fostering advances in nanotechnology from multiple locations along the nanotechnology value chain in looking at the promises and pitfalls of state-led economic development.

    This report focuses on lithium-ion (Li-ion) battery technology applications for two- and possibly three-wheeled vehicles. The author of this report visited the People's Republic of China (PRC or China) to assess the status of Li-ion battery technology there and to analyze Chinese policies, regulations, and incentives for using this technology and for using two- and three-wheeled vehicles. Another objective was to determine if the Li-ion batteries produced in China were available for benchmarking in the United States. The United States continues to lead the world in Li-ion technology research and development (R&D). Its strong R&D program is funded by the U.S. Department of Energy and other federal agencies, such as the National Institute of Standards and Technology and the U.S. Department of Defense. In Asia, too, developed countries like China, Korea, and Japan are commercializing and producing this technology. In China, more than 120 companies are involved in producing Li-ion batteries. There are more than 139 manufacturers of electric bicycles (also referred to as E-bicycles, electric bikes or E-bikes, and electric two-wheelers or ETWs in this report) and several hundred suppliers. Most E-bikes use lead acid batteries, but there is a push toward using Li-ion battery technology for two- and three-wheeled applications. Highlights and conclusions from this visit are provided in this report and summarized.

    2015-12-01

    Since the Wenchuan earthquake in 2008, a dramatic progress on earthquake early warning (EEW) has been made by Institute of Care-life (ICL) in China. The research on EEW by ICL covers choosing appropriate sensors, methods of installing the sensors, data automatic process methods of the seismic waves for EEW, methods of applying of EEW warnings for public, schools and life-line projects. ICL innovatively applies distributed computing and cloud computing technology. So far, ICL has deployed over 5500 EEW sensors in China, which is 5 times the number of EEW sensors in Japan, covering more than 2.1 million square kilometers. Since June, 2011, over 5000 earthquakes, with 28 of them are destructive quakes, have triggered the EEWS with no false alert. The root mean square (RMS) error of the magnitude for the 28 destructive quakes is 0.32. In addition, innovative work is done to suppress false alarm and miss alarm, which pushes forward the application of EEW in China. The technology is also being applied in Nepal now.

    2014-01-01

    The sudden and violent nature of coal and gas outbursts continues to pose a serious threat to coal mine safety in China. One of the key issues is to predict the occurrence of outbursts. Current methods that are used for predicting the outbursts in China are considered to be inadequate, inappropriate or impractical in some seam conditions. In recent years, Huainan Mining Industry Group (Huainan) in China and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia have been jointly developing technology based on gas content in coal seams to predict the occurrence of outbursts in Hua-inan. Significant progresses in the technology development have been made, including the development of a more rapid and accurate system in determining gas content in coal seams, the invention of a sam-pling-while-drilling unit for fast and pointed coal sampling, and the coupling of DEM and LBM codes for advanced numerical simulation of outburst initiation and propagation. These advances are described in this paper.

    1993-10-01

    This paper summarizes the energy-efficiency potential in three major regions of the world -- the Former Soviet Union, Eastern Europe, and China and discusses policy measures that might stimulate adoption of technologies that constitute that potential. The authors suggest that major gains in energy efficiency are indeed possible, and that capturing this potential would provide a major reduction in future levels of energy-related carbon dioxide emissions. The authors indicate, however, that the requisite technological improvement -- often referred to as technology transfer -- is unlikely without the stimulus of strong policy measures. These measures include the rapid introduction of market mechanisms as well as policy intervention to overcome significant market barriers. Moreover, we observe that strong policies -- heavy taxes and performance standards are becoming increasingly unpopular and problematic, but can be replaced to some extent by incentive, market-pull, and research and development programs.

    2015-11-04

    Monoclonal antibodies (mAbs), as an emerging technology, have become increasingly important in the development of human therapeutic agents. How developing countries such as China could seize this emerging technological opportunity remains a poorly studied issue in prior literature. Thus, this paper aims to investigate the research and development of mAbs in China based on an innovation system functions approach and probes into the question of how China has been taking advantage of emerging technologies to overcome its challenges of building up a complete innovation system in developing mAbs. Mixed research methods were applied by combining archival data and field interviews. Archival data from the China Food and Drug Administration, Web of Science, the United States Patent and Trademark Office, the Chinese Clinical Trial Registry, and the National Science and Technology Report Service were used to examine the status quo of the technology and research and development (R&D) activities in China, while the opinions of researchers and managers in this field were synthesized from the interviews. From the perspective of innovation system functions, technological development of mAb in China is being driven by incentives such as the subsidies from the State and corporate R&D funding. Knowledge diffusion has been well served over the last 10 years through exchanging information on networks and technology transfer with developed countries. The State has provided clear guidance on search of emerging mAb technologies. Legitimacy of mAb in China has gained momentum owing to the implementation of government policies stipulated in the "The Eleventh Five-year Plan" in 2007, as well as national projects such as the "973 Program" and "863 Program", among others. The potential of market formation stays high because of the rising local demand and government support. Entrepreneurial activities for mAb continue to prosper. In addition, the situation of resource supply has been improved

  1. The Deployment of Low Carbon Technologies in Energy Intensive Industries: A Macroeconomic Analysis for Europe, China and India

    Full Text Available Industrial processes currently contribute 40% to global CO2 emissions and therefore substantial increases in industrial energy efficiency are required for reaching the 2 °C target. We assess the macroeconomic effects of deploying low carbon technologies in six energy intensive industrial sectors (Petroleum, Iron and Steel, Non-metallic Minerals, Paper and Pulp, Chemicals, and Electricity in Europe, China and India in 2030. By combining the GAINS technology model with a macroeconomic computable general equilibrium model, we find that output in energy intensive industries declines in Europe by 6% in total, while output increases in China by 11% and in India by 13%. The opposite output effects emerge because low carbon technologies lead to cost savings in China and India but not in Europe. Consequently, the competitiveness of energy intensive industries is improved in China and India relative to Europe, leading to higher exports to Europe. In all regions, the decarbonization of electricity plays the dominant role for mitigation. We find a rebound effect in China and India, in the size of 42% and 34% CO2 reduction, respectively, but not in Europe. Our results indicate that the range of considered low-carbon technology options is not competitive in the European industrial sectors. To foster breakthrough low carbon technologies and maintain industrial competitiveness, targeted technology policy is therefore needed to supplement carbon pricing.

    The German Postal Reform Ⅰ in 1989 introduced competition in the mobile cellular market. German cellular operators, DeTeMobil, Mannesmann, E-Plus and VIAG Interkom, built D1-, D2-, El-and E2-Netze based on GSM standards made in Europe. China Unicom was created in 1994 and China Telecom was separated from MPT in 1995. China Telecom and China Unicom competed in a duopoly from the mid-1990s onwards and the cellular services provided by them also rely on GSM standards. China Telecom additionally deployed XLT technology (PHS) from the late 1990s onwards. While DeTeMobil and Mannesmann conquered approximately 80%-90% of the market throughout the 1990s and were the two dominant market players in Germany, China's cellular market was mainly controlled by China Mobile. In Germany, prices related to cellular technology continued the downwards trend as a major result of the process of deregulation, liberalisation and competition. In China, price wars had led to significant price reductions in the cellular market. Although network operators in both countries strived to deliver differentiated cellular services, the two national markets in the 1990s were visibly shaped by product homogeneity.

    The development of high-tech industry has been prosperous around the world in past decades, while technology and finance have already become the most significant issues in the information era. While high-tech firms are a major force behind a country's economic development, it requires a lot of money for the development process, as well as the financing difficulties for its potential problems, thus, how to evaluate and establish appropriate technology and financial services platforms innovation strategy has become one of the most critical and difficult issues. Moreover, how the chosen intertwined financial environment can be optimized in order that high-tech firms financing problems can be decided has seldom been addressed. Thus, this research aims to establish a technology and financial services platform innovation strategy improvement model, as based on the hybrid MADM model, which addresses the main causal factors and amended priorities in order to strengthen ongoing planning. A DEMATEL technique, as based on Analytic Network Process, as well as modified VIKOR, will be proposed for selecting and re-configuring the aspired technology and financial services platform. An empirical study, as based on China's technology and financial services platform innovation strategy, will be provided for verifying the effectiveness of this proposed methodology. Based on expert interviews, technology and financial services platforms innovation strategy improvement should be made in the following order: credit guarantee platform (C)_credit rating platform (B)_investment and finance platform (A).

    2004-01-01

    Polycarbonate (hereinafter referred to as "PC ") is the sole product having good transparency among the 5 major engineering plastics. In 2000, the worldwide PC production capacity was reached up to 2,800,000 tons of several hundreds of brands of various grades. It is estimated that the global PC production capacity will exceed 3,500,000 tons in 2005. The global demand for PC was 1,900,000 tons in 2000, which will reach to 2,600,000 tons and more than 3,000,000 tons in 2003 and 2005 respectively according to relevant estimations. The total production capacity of PC of the whole country reached to 3000-4000 tons in 2003. PC imported to China in 2003 was up to 534,000 tons and the apparent amount of consumption of that year was 447,000 tons.The scientific and technical personnel of Chenguang Chemical Research Institute engaged in the research and development of PC production technologies have been advancing wave upon wave with a combatant spirit and the spirit of "Storming the gate" for more than 40 years, having made important breakthroughs in a continuous PC manufacturing process by using ester-interchange method and in project amplification techniques. We consider that favorable conditions are now already available in China for building up PC production plants (each has an annual production capacity of 10,000 tons or above) by using ester- interchange method.In the recent 2 years, the growth rate of domestic annual PC consumption was up to more than 30 %, almost all of which relied on imports from foreign countries. Consequently, the development of domestically made PC has become a task, which brooks no delay. At present, conditions for building up domestic large-scale PC production plants are already available. It should be noted that PC production technologies are matured, PC products have a huge market potential and the returns on investment are optimistic. Therefore, building PC production plants, each with an annual production capacity of 10,000 tons ( approx

    The UMTS auction in 2000 brought approximately 100 billion DM (Deutsche Mark) for the German National Treasury. T-Mobile (D1-Netz), Vodafone (D2-Netz), E-Plus (E1-Netz) and 02 (E2-Netz) have gradually evolved from GSM to full-fledged UMTS operators over the past years. The conglomerate of China Telecom was split twice. China acceded to WTO and promulgated the FITE Provisions. MIIT (Ministry of Industry and Information Technology) became the regulator and China Netcom was incorporated into China Unicorn in 2008. Most recently the layout of 3G future has been reconfirmed by MIIT. Voice service has remained the main source of income in both countries and operators have continued to focus on voice quality and network availability in their respective 2G networks. Because value-added and higher-speed data applications have been gaining market attention, 2.5G and 3G infrastructure has increasingly become the focal network strategy for the operators since the beginning of the new century. Germany has rolled out WCDMA/UMTS services on a large scale in the consumer market, while China has adopted all three 3G standards (TD-SCDMA, WCDMA/UMTS, CDMA2000), which shall gradually capture a wider 3G subscriber base. The summary shows that the development of the cellular technology and market in Germany and China can be discussed in three distinct historical periods. The conclusion suggests that the case of the cellular technology appears to be consistent with and applicable to a number of arguments widely disputed in economics and management related to technology and innovation, such as dominant design, technology waves/ S-Curve, disruptive technologies, Technology Adoption Life Cycle.

    2017-09-01

    This article discusses why Chinese space programs were able to develop to the extent they did during the turbulent decade of the Cultural Revolution (1966-1976). It first introduces briefly what China had accomplished in rocket and missile technology before the Cultural Revolution, including the establishment of a system for research and manufacturing, breakthroughs in rocket technology, and programs for future development. It then analyzes the harmful impacts of the Cultural Revolution on Chinese space programs by examining activities of contemporary mass factions in the Seventh Ministry of Machinery Industry. In the third section, this article presents the important developments of Chinese space programs during the Cultural Revolution and explores briefly the significance of these developments for the future and overall progress in space technology. Finally, it discusses the reasons for the series of developments of Chinese space technology during the Cultural Revolution. This article concludes that, although the Cultural Revolution generated certain harmful impacts on the development of Chinese space technology, the Chinese essentially accomplished their scheduled objectives in their space program, both because of the great support of top Chinese leaders, including the officially disgraced Lin Biao and the Gang of Four, and due to the implementation of many effective special measures.

    While the shortage of water and energy is a well-recognized worldwide natural resources issue, little attention has been given to irrigation energy efficiency. In this paper, we examine the potential energy savings that can be achieved by implementing improved irrigation technologies in China. The use of improved irrigation management measures such as a flow meter, irrigation scheduling, and/or regular maintenance and upgrades, typically reduces the amount of water pumped over the course of a growing season. The total energy saved by applying these improved measures could reach 20%, as compared with traditional irrigation methods. Two methods of irrigation water conveyance by traditional earth canal and low pressure pipeline irrigation (LPPI) were also evaluated. Our study indicated that LPPI could save 6.48×109 kWh yr-1 when applied to 11 Chinese provinces. Also, the CO2 emission was reduced by 6.72 metric tons per year. Among these 11 surveyed provinces, the energy saving potential for two provinces, Hebei and Shandong, could reach 1.45×109 kWh yr-1. Using LPPI, potential energy saved and CO2 emissions reduced in the other 20 Chinese provinces were estimated at about 2.97×109 kWh yr-1 and 2.69 metric tons per year, respectively. The energy saving potential for Heilongjiang, a major agriculture province, could reach 1.77×109 kWh yr-1, which is the largest in all provinces. If LPPI is applied to the entire country, average annual energy saving of more than 9 billion kWh and average annual CO2 emission reduction of more than 9.0 metric tons could be realized. Rice is one of the largest users of the world’s fresh water resources. Compared with continuous flooding irrigation, intermittent irrigation (ITI) can improve yield and water-use efficiency in paddy fields. The total increments of net output energy and yield by ITI in paddy fields across China could reach 2.5×1016 calories and 107 tons, respectively. So far only a small part of agricultural land in China

    After more than 10 years efforts on awareness raising and promotion, the concept of cleaner production (CP) has been adopting as a strategic approach m balance economic benefits and environmental protection for China's industries.However, it is also found that dean technology is difficult to be adopted and implemented in Chinese Small and Medium-sized Enterprises (SMEs) because of certain barriers. This paper investigates these barriers among three stakeholders-governments,enterprises and experts. The Analytic Hierarch Process (AHP) was employed to prioritize the relative importance of the twenty fine-selected barriers, which were classified into four barrier categories. The findings reveal that the exterior barriers of policy and financial barriers should be stressed rather than the inner barriers of technical and managerial barriers,although they are also very important. Absence of incentives on economic policies, lax enforcement of enwronmental regulations and high initial capital cost were the most important barriers to adoption of Clean Technologies (CT)in China.

    Full Text Available Objectives. To systematically review and analyze the current status and characteristics of usability studies in China in the field of information technology in general and in the field of healthcare in particular. Methods. We performed a quantitative literature analysis in three major Chinese academic databases and one English language database using Chinese search terms equivalent to the concept of usability. Results. Six hundred forty-seven publications were selected for analysis. We found that in China the literature on usability in the field of information technology began in 1994 and increased thereafter. The usability definitions from ISO 9241-11:1998 and Nielsen (1993 have been widely recognized and cited. Authors who have published several publications are rare. Fourteen journals have a publishing rate over 1%. Only nine publications about HIT were identified. Discussions. China’s usability research started relatively late. There is a lack of organized research teams and dedicated usability journals. High-impact theoretical studies are scarce. On the application side, no original and systematic research frameworks have been developed. The understanding and definition of usability is not well synchronized with international norms. Besides, usability research in HIT is rare. Conclusions. More human and material resources need to be invested in China’s usability research, particularly in HIT.

    Even though technology transfer has been part of development aid programmes for many decades, it has more often than not failed to come to fruition. One reason is the absence of simple guidelines or decision making tools that help operators or plant owners to decide on the most suitable technology to adopt. Practical suggestions for choosing the most suitable technology to combat a specific problem are hard to get and technology drawbacks are not sufficiently highlighted. Western counterparts in technology transfer or development projects often underestimate or don't sufficiently account for the high investment costs for the imported incineration plant; the differing nature of Chinese MSW; the need for trained manpower; and the need to treat flue gas, bunker leakage water, and ash, all of which contain highly toxic elements. This article sets out requirements for municipal solid waste disposal plant owner/operators in China as well as giving an attribute assessment for the prevalent waste disposal plant types in order to assist individual decision makers in their evaluation process for what plant type might be most suitable in a given situation. There is no 'best' plant for all needs and purposes, and requirement constellations rely on generalisations meaning they cannot be blindly applied, but an alignment of a type of plant to a type of owner or operator can realistically be achieved. To this end, a four-step approach is suggested and a technology matrix is set out to ease the choice of technology to transfer and avoid past errors. The four steps are (1) Identification of plant owner/operator requirement clusters; (2) Determination of different municipal solid waste (MSW) treatment plant attributes; (3) Development of a matrix matching requirement clusters to plant attributes; (4) Application of Quality Function Deployment Method to aid in technology localisation. The technology transfer matrices thus derived show significant performance differences between the

    field experiments using the Biochar technology. Here we report the results. As a province with the dominating agriculture, Guizhou produces 10~30 million tons of crop stalks annually, of which roughly 10% were used as fodder of domestic animals or in some other ways while most were subject to the notorious field combustion. The provincial government has issued policies calling for the exploitation of this renewable resource, no breakthrough, however, has been made toward this goal due to the low economic benefit of the current straw use technologies. Should the straws be used in the biochar way, based on our data of field experiments in Guizhou province, the biomass could yield 300~900 thousand tons of charcoal, which would sequester the atmospheric CO2 by 10~30 million tons. Meanwhile the application of the biochar in the basic farmland would enhance the production of corn and rapeseed by about 30%, and the total production of crop by 300 thousand tons. The increased benefit from these two sources is equivalent to a total of 6600 million RMB, or 244 Yuan per capita of farmers per year in the whole province. This income would enable 850 thousand hectares of hill slopes to be relieved from cultivation without impairing the food security. This area accounts for 25% of the total rocky desertification of the province, or 65% of its medium ~severe desertified hillsides. *This research was financially supported by the Strategic Priority Research Program of the Chinese Academy of Sciences (No. XDA05070400), the National Natural Science Foundation of China (No. 41021062, 40872212) and the Key Technologies R & D Project in Agriculture of Guizhou Province (No.[2011]3079).

    China has endured the increasing generation of municipal solid waste; hence, environmental analysis of current waste management systems is of crucial importance. This article presents a comprehensive life cycle assessment of three waste treatment technologies practiced in Hangzhou, China: landfill with and without energy recovery, and incineration with waste-to-energy. Adopting region-specific data, the study covers various environmental impacts, such as global warming, acidification, nutrient enrichment, photochemical ozone formation, human toxicity and ecotoxicity. The results show that energy recovery poses a positive effect in environmental savings. Environmental impacts decrease significantly in landfill with the utilization of biogas owing to combined effects by emission reduction and electricity generation. Incineration is preferable to landfill, but toxicity-related impacts also need to be improved. Furthermore, sensitivity analysis shows that the benefit of carbon sequestration will noticeably decrease global warming potential of both landfill scenarios. Gas collection efficiency is also a key parameter influencing the performance of landfill. Based on the results, improvement methods are proposed. Energy recovery is recommended both in landfill and incineration. For landfill, gas collection systems should be upgraded effectively; for incineration, great efforts should be made to reduce heavy metals and dioxin emissions.

    This article estimates the impacts of health information technology (HIT) on health-care delivery in the Wenchuan County of China, where the devastation of the 2008 Great Wenchuan Earthquake and the subsequent large-scale HIT implementation (the Healthy Wenchuan Program) offers a 'natural experiment' opportunity, enabling us to conduct a difference-in-difference evaluation of the potential benefits of HIT on accessibility, affordability and appropriateness of health-care services in the underdeveloped rural area. Based on data collected from two field surveys in township hospitals, we find that for both the inpatient and outpatient samples, the HIT system promotes access to medical care by increasing doctor referrals and encouraging within-county medical utilization, reduces patient financial burden in certain expenditure categories, and contributes to higher patient satisfaction on medical care quality. On the other hand, we also find that HIT leads to increased patient waiting time for hospital registration, reflecting the unique challenges in implementing HIT in the underdeveloped areas. Our study contributes to the growing body of literature on evaluating the impacts of HIT application in the developing regions, and provides implications on the potential role of HIT in China's national health system reforms.

    2016-06-01

    Full Text Available Through critical analysis of selected news stories from sina.com from 2010 to 2015 about cell phones and “left-behind children” in China, this article examines media discourses on the relationship between migrant families and communication technology. The author finds that the roles of cell phones in their lives are portrayed in the following narratives: 1 cell phones are highly valuable for connecting family members living apart; 2 cell phones are used as a problem-solver in charity giving and rural development projects; 3 cell phones can bring unexpected risks to children lacking media literacy; and 4 cell phones could harbour or unleash evil—associated with increasing cases of juvenile delinquency or crime stories. The author discusses how the different institutional goals of social agencies, corporations, educators, and law enforcement contribute to the polarity of the discourses, reflecting the societal anxieties over unsupervised use of mobile devices by adolescents, as well as the cultural and political implications of empowering the “have-nots” of the digital divide by improving access to communication technology.

  15. AN ASSESSMENT OF LAND USE CHANGES IN FUQING COUNTY OF CHINA USING REMOTE SENSING TECHNOLOGY

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Fuqing County of southeast China has witnessed significant land use changes during the last decade. Remote sensing technology using multitemporal Landsat TM images was used to characterize land use types and to monitor land use changes in the county. Two TM scenes from 1991 and 1996 were used to cover the county and a five-year time period. Digital image processing was carried out for the remotely sensed data to produce classified images. The images were further processed using GIS software to generate GIS databases so that the data could be further spatially analyzed taking the advantages of the software. Land use change areas were determined by using the change detection technique. The comparison of the two classified TM images using the above technologies reveals that during the five study years, a large area of arable lands in the county has been lost and deforestation has taken place largely because of the dramatic increase in built-up land and orchard. The conclusive statistical information is useful to understand the processes, causes and impacts of the land use changes in the county. The major driving force to the land use changes in the county appeared to be the rapid economic development. The decision makers of the county have to pay more attention to the land use changes for the county′ s sustainable development.

    Pattern design and, technology play a very important role in the garment industry. In order to improve the level of pattern making and design of the garment industry, a survey was conducted to investigate the industrial needs in pattern design and technology in mainland China. The data were collected from the employers and employees from the garment industry and students in the major of fashion and clothing studies. It indicated that there was a gap between the employer and employee, especially the requirements of the industrial needs and the course contents covered by the tertiary schools. The employers expected to recruit more experienced pattern designers, at the same time, they were not reluctant to hire fresh graduates and spent more resources on the training of employees. The students knew little about their employment situation of the garment industry, spent too little time on the course study and learned too little practical skills in pattern design. They could not make use of the knowledge which prevented them from being employed by the garment industry. Efforts should be taken by both the tertiary schools and the garment industry. The students should be aspirated towards the profession of pattern cutters and the syllabuses of pattern making should be more practical and industrial orientated. The solution might benefit the garment industry a lot in a long run.

    Full Text Available Mushrooms traditionally collected from forests and now more cultivated have recently become the products of the fifth-largest agricultural sector in China. It was estimated that more than 25 million farmers in China are currently engaged in the collection, cultivation processing and marketing of mushrooms. The total value of mushroom products amounted to 149 billion RMB Yuan (24 billion USD in 2011. The raw materials have expanded from a few hardwoods to a variety of woods and increasing more into agricultural residues and wastes. The average annual growth rate has been over 10% over the past 30 years in China. This paper describes the rapid growth of mushroom cultivation and its contribution to food security and rural sustainable development. The roles of bio-innovation, technological dissemination, and marketing are also examined. Mushrooms could potentially be very important in future food supplies and in new dimensions of sustainable agriculture and forestry.

    Site selection is an important and necessary issue for waste management in fast-growing regions. Because of the complexity of waste management systems, the selection of the appropriate solid waste landfill site requires consideration of multiple alternative solutions and evaluation criteria. Based on actual conditions of the study area, we considered economic factors, calculated criteria weights using the analytical hierarchy process (AHP), and built a hierarchy model for solving the solid waste landfill site-selection problem in Beijing, China. A geographic information system (GIS) was used to manipulate and present spatial data. All maps are graded from 1 (lowest suitability) to 5 (highest suitability) using spatial information technologies. The candidate sites were determined by aggregation based on the criteria weights. The candidate sites are divided by 'best', 'good' and 'unsuitable' landfill areas. Best landfill areas represent optimal sites; good landfill areas can be used as back-up candidate sites. Our work offers a sitting methodology and provides essential support for decision-makers in the assessment of waste management problems in Beijing and other rapidly developing cities in developing countries.

    The production of biochar by pyrolysis and its application to soil can sequester the CO2 which was absorbed by plants from atmosphere into soil, in addition it can also bring multiple benefits for agriculture production. On the basis of the available potential survey of the biomass residues from agriculture and forestry section, life cycle assessment was employed to quantify the potential of biochar technology in mitigation of greenhouse gases in our country. The results showed: In China, the amount of available biomass resource was 6.04 x 10(8) t every year and its net greenhouse effect potential was 5.32 x 10(8) t CO(2e) (CO(2e): CO2 equivalent), which was equivalent to 0.88 t CO(2e) for every ton biomass. The greatest of contributor to the total potential was plant carbon sequestration in soil as the form of biochar which accounts for 73.94%, followed by production of renewable energy and its percentage was 23.85%. In summary, production of biochar from agriculture and forestry biomass residues had a significant potential for our country to struggle with the pressure of greenhouse gas emission.

    China is the world`s fourth largest electric power producer, and is expected to surpass Japan within the next two years to become the third largest power producer. During the past 15 years, China`s total electricity generation more than tripled, increasing from about 300 TWh to about 1,000 TWh. Total installed generating capacity grew at an average of 8.2 percent per year, increasing from 66 to 214 GW. The share of China`s installed capacity in Asia increased from 21 to 31 percent. The Chinese government plans to continue China`s rapid growth rate in the power sector. Total installed capacity is planned to reach 300 GW by 2000, which will generate 1,400 TWh of electricity per year. China`s long-term power sector development is subject to great uncertainty. Under the middle scenario, total capacity is expected to reach 700 GW by 2015, with annual generation of 3,330 TWh. Under the low and high scenarios, total capacity will reach 527-1,005 GW by 2015. The high scenario representing possible demand. To achieve this ambitious scenario, dramatic policy changes in favor of power development are required; however, there is no evidence that such policy changes will occur at this stage. Even under the high scenario, China`s per capita annual electricity consumption would be only 3,000 kWh by 2015, less than half of the present per capita consumption for OECD countries. Under the low scenario, electricity shortages will seriously curb economic growth.

    China, which has pursued aggressive policies to encourage economic development, could experience the world`s fastest growth in energy consumption over the next two decades. China has become the third largest energy user in the world since 1990 when primary energy consumption reached 960 million tons of coal equivalent (tce). Energy use is increasing at an annual rate of 6-7% despite severe infrastructure and capital constraints on energy sector development. Energy consumption in China is heavily dominated by coal, and fossil fuels provide up to 95% of all commercial energy use. Coal currently accounts for 77% of total primary energy use; oil, 16%; hydropower, 5%; and natural gas, 2%. Coal is expected to continue providing close to three-quarters of all energy consumed, and the amount of coal used is expected to triple by year 2020. Currently, renewable energy resources (except for hydropower) account for only a fraction of total energy consumption. However, the estimated growth in greenhouse gas emissions, as well as serious local and regional environmental pollution problems caused by combustion of fossil fuels, provides strong arguments for the development of renewable energy resources. Renewable energy potential in China is significantly greater than that indicated by the current level of use. With a clear policy goal and consistent efforts from the Government of China, renewables can play a far larger role in its future energy supply.

    2011-01-01

    With the increasing attention on developing a low-carbon economy, it is necessary to seek appropriate ways on reducing greenhouse gas (GHG) emissions through innovative municipal solid waste management (MSWM), such as urban symbiosis. However, quantitative assessments on the environmental benefits of urban symbiosis, especially in developing countries, are limited because only a limited number of planned synergistic activities have been successful and it is difficult to acquire detailed inventory data from private companies. This paper modifies and applies a two-step simulation system and used it to assess the potential environmental benefits, including the reduction of GHG emissions and saving of fossil fuels, by employing various Japanese plastics recycling/energy-recovery technologies in Shenyang, China. The results showed that among various recycling/energy-recovery technologies, the mechanical waste plastics recycling technology, which produces concrete formwork boards (NF boards), has the greatest potential in terms of reducing GHG emissions (1.66 kg CO(2)e/kg plastics), whereas the technology for the production of refuse plastic fuel (RPF) has the greatest potential on saving fossil fuel consumption (0.77 kg ce/kg-plastics). Additional benefits can be gained by applying combined technologies that cascade the utilization of waste plastics. Moreover, the development of clean energy in conjunction with the promotion of new waste plastics recycling programs could contribute to additional reductions in GHG emissions and fossil fuel consumption.

    Science and technology systems - and their epistemic communities - are usually hierarchical and composed of a number of strong, large, leading organizations, along with a number of smaller and less influential ones. Moreover, these hierarchical patterns have a spatial structure: the leading organizations are concentrated in a few places, creating a science and technology center, whereas the majority of locations are peripheral. In the example of biotech research in China, we found dynamic changes in center-periphery patterns. These results are based on a network analysis of evolving co-authorship networks from 2001 to 2009 that were built combining national and international databases. Therefore, our results are not only relevant for evaluating the spatial structure and dynamics in the Chinese biotech system and its integration into the global knowledge network, but also revive a discussion on persistence and processes of change in the systems theory for sciencebased industries.

However, its coal seams are of lower permeability, which are not conductive to coalbed methane (CBM drainage. In this study, based on the theory of the ground movement, we analyzed the principle of coal and CBM coextraction in the Yangquan coalfield, and established the technology system of coal and CBM coextraction which was further implemented in the coal and CBM coextraction in the Yangquan coalfield. The coal and CBM coextraction technologies based on the “pressure-relief and permeability-increase” effect caused by the mining overburden movement can optimally ensure the safe and efficient mining and improve the gas drainage rate. A series of developed coal and CBM coextraction technologies for the Yangquan coalfield were mainly characterized by the high-level gas drainage roadway. This reached a maximum gas drainage amount of 270,000 m3/day for single drainage roadway and a pressure-relief gas drainage rate of >90%. Those technologies significantly improved the gas drainage effect safely and efficiently achieving the coal and CBM coextraction.

    China’s cement and steel industry accounts for approximately half of the world’s total cement and steel production. These two industries are two of the most energy-intensive and highest carbon dioxide (CO2)-emitting industries and two of the key industrial contributors to air pollution in China. For example, the cement industry is the largest source of particulate matter (PM) emissions in China, accounting for 40 percent of its industrial PM emissions and 27 percent of its total national PM emissions. The Chinese steel industry contributed to approximately 20 percent of sulfur dioxide (SO2) emissions and 27 percent of PM emissions for all key manufacturing industries in China in 2013. In this study, we analyzed and projected the total PM and SO2 emissions from the Chinese cement and steel industry from 2010–2050 under three different scenarios: a Base Case scenario, an Advanced scenario, and an Advanced EOP (end-of-pipe) scenario. We used bottom-up emissions control technologies data and assumptions to project the emissions. In addition, we conducted an economic analysis to estimate the cost for PM emissions reductions in the Chinese cement industry using EOP control technologies, energy efficiency measures, and product change measures. The results of the emissions projection showed that there is not a substantial difference in PM emissions between the Base Case and Advanced scenarios, for both the cement and steel industries. This is mainly because PM emissions in the cement industry caused mainly by production process and not the fuel use. Since our forecast for the cement production in the Base Case and Advanced scenarios are not too different from each other, this results in only a slight difference in PM emissions forecast for these two scenarios. Also, we assumed a similar share and penetration rate of control technologies from 2010 up to 2050 for these two scenarios for the cement and steel industry. However, the Advanced EOP

    2013-01-01

    Water inrush and mud gushing are one of the biggest hazards in tunnel construction. Unfavorable geo-logical sections can be observed in almost all railway tunnels under construction or to be constructed, and vary in extent. Furthermore, due to the different heights of mountains and the lengths of tunnels, the locations of the unfavorable geological sections cannot be fully determined before construction, which increases the risk of water inrush and mud gushing. Based on numerous cases of water inrush and mud gushing in railway tunnels, the paper tries to classify water inrush and mud gushing in railway tunnels in view of the conditions of the surrounding rocks and meteorological factors associated with tunnel excavation. In addition, the causes of water inrush and mud gushing in combination of macro-and micro-mechanisms are summarized, and site-specific treatment method is put forward. The treatment methods include choosing a method of advance geological forecast according to risk degrees of different sec-tions in the tunnel, determining the items of predictions, and choosing the appropriate methods, i.e. draining-oriented method, blocking-oriented method or draining-and-blocking method. The treatment technologies of railway water inrush and mud gushing are also summarized, including energy relief and pressure relief technology, advance grouting technology, and advance jet grouting technology associated with their key technical features and applicable conditions. The results in terms of treatment methods can provide reference to the prevention and treatment of tunnel water inrush and mud gushing.

A recently developed site-specific nutrient management (SSNM) can reduce fertilizer-N use while preventing the yield from falling. In this paper, we raise the question of fertilizer N application in rice production through a survey of farmers' practice of fertilizer N in 18 villages of four provinces. The average rate of N application for rice production in the 18 villages was 190 kg/ha, and 76% to 100% of the total fertilizer N which was applied within 10 days after transplanting resulted in lots of nitrate leached into water.Furthermore, we tested the effect of SSNM through farmer participatory trial. The SSNM technology maintained rice yields with significantly less fertilizer N and there was no increase in labor input, as much as 31% fertilizer N were saved with the SSNM technology. Finally, the paper points that extension and further research of the SSNM technology should be an effective method to deal with the contradiction of population, food and nitrate non-point pollution of water resource and promote the sustainability of agriculture.

    This paper, which focuses on emissions from China's coal-fired power plants during 1990-2010, is the second in a series of papers that aims to develop a high-resolution emission inventory for China. This is the first time that emissions from China's coal-fired power plants were estimated at unit level for a 20-year period. This inventory is constructed from a unit-based database compiled in this study, named the China coal-fired Power plant Emissions Database (CPED), which includes detailed information on the technologies, activity data, operation situation, emission factors, and locations of individual units and supplements with aggregated data where unit-based information is not available. Between 1990 and 2010, compared to a 479 % growth in coal consumption, emissions from China's coal-fired power plants increased by 56, 335, and 442 % for SO2, NOx, and CO2, respectively, and decreased by 23 and 27 % for PM2.5 and PM10 respectively. Driven by the accelerated economic growth, large power plants were constructed throughout the country after 2000, resulting in a dramatic growth in emissions. The growth trend of emissions has been effectively curbed since 2005 due to strengthened emission control measures including the installation of flue gas desulfurization (FGD) systems and the optimization of the generation fleet mix by promoting large units and decommissioning small ones. Compared to previous emission inventories, CPED significantly improved the spatial resolution and temporal profile of the power plant emission inventory in China by extensive use of underlying data at unit level. The new inventory developed in this study will enable a close examination of temporal and spatial variations of power plant emissions in China and will help to improve the performances of chemical transport models by providing more accurate emission data.

    The exploration and exploitation of deep-water oil-gas are apt to be suffered from high-risk geo-hazards such as submarine landslide, soft clay creep, shallow gas, excess pore-water pressure, mud volcano or mud diaper, salt dome and so on. Therefore, it is necessary to survey the seafloor topography, identify the unfavourable geological risks and investigate their environment and mechanism before exploiting the deep-water oil-gas. Because of complex environment, the submarine phenomenon and features, like marine geohazards, can not be recognized directly. Multi-disciplinary data are acquired and analysed comprehensively in order to get more clear understanding about the submarine processes. The data include multi-beam bathymetry data, sidescan sonar images, seismic data, shallow-bottom profiling images, boring data, etc.. Such data sets nowadays increase rapidly to large amounts, but may be heterogeneous and have different resolutions. It is difficult to make good management and utilization of such submarine data with traditional means. GIS technology can provide efficient and powerful tools or services in such aspects as spatial data management, processing, analysis and visualization. They further promote the submarine scientific research and engineering development. The Liwan 3-1 Gas Field, the first deep-water gas field in China, is located in the Zhu II Depression in the Zhujiang Basin along the continental slope of the northern South China Sea. The exploitation of this field is designed to establish subsea wellhead and to use submarine pipeline for the transportation of oil. The deep-water section of the pipeline route in the gas field is to be selected to pass through the northern continental slope of the South China Sea. To avoid huge economic loss and ecological environmental damage, it is necessary to evaluate the geo-hazards for the establishment and safe operation of the pipeline. Based on previous scientific research results, several survey cruises have

    In China, local governments of many areas prefer to give priority to the development of heavy industrial clusters in pursuit of high value of gross domestic production (GDP) growth to get political achievements, which usually results in higher costs from ecological degradation and environmental pollution. Therefore, effective methods and reasonable evaluation system are urgently needed to evaluate the overall efficiency of industrial clusters. Emergy methods links economic and ecological systems together, which can evaluate the contribution of ecological products and services as well as the load placed on environmental systems. This method has been successfully applied in many case studies of ecosystem but seldom in industrial clusters. This study applied the methodology of emergy analysis to perform the efficiency of industrial clusters through a series of emergy-based indices as well as the proposed indicators. A case study of Shenyang Economic Technological Development Area (SETDA) was investigated to show the emergy method's practical potential to evaluate industrial clusters to inform environmental policy making. The results of our study showed that the industrial cluster of electric equipment and electronic manufacturing produced the most economic value and had the highest efficiency of energy utilization among the four industrial clusters. However, the sustainability index of the industrial cluster of food and beverage processing was better than the other industrial clusters.

    2009-02-01

    Full Text Available The spatial distribution of population is closely related to land use and land cover (LULC patterns on both regional and global scales. Population can be redistributed onto geo-referenced square grids according to this relation. In the past decades, various approaches to monitoring LULC using remote sensing and Geographic Information Systems (GIS have been developed, which makes it possible for efficient updating of geo-referenced population data. A Spatial Population Updating System (SPUS is developed for updating the gridded population database of China based on remote sensing, GIS and spatial database technologies, with a spatial resolution of 1 km by 1 km. The SPUS can process standard Moderate Resolution Imaging Spectroradiometer (MODIS L1B data integrated with a Pattern Decomposition Method (PDM and an LULC-Conversion Model to obtain patterns of land use and land cover, and provide input parameters for a Population Spatialization Model (PSM. The PSM embedded in SPUS is used for generating 1 km by 1 km gridded population data in each population distribution region based on natural and socio-economic variables. Validation results from finer township-level census data of Yishui County suggest that the gridded population database produced by the SPUS is reliable.

    2009-06-03

    With both China and the United States relying heavily on coal for electricity, senior government officials from both countries have urged immediate action to push forward technology that would reduce carbon dioxide emissions from coal-fired plants. They discussed possible actions at a high-level workshop in April 2009 at the Harvard Kennedy School jointly sponsored by the Belfer Center's Energy Technology Innovation Policy (ETIP) research group, China's Ministry of Science and Technology, and the Chinese Academy of Sciences. The workshop examined issues surrounding Integrated Gasification Combined Cycle (IGCC) coal plants, which turn coal into gas and remove impurities before the coal is combusted, and the related carbon capture and sequestration, in which the carbon dioxide emissions are captured and stored underground to avoid releasing carbon dioxide into the atmosphere. Though promising, advanced coal technologies face steep financial and legal hurdles, and almost certainly will need sustained support from governments to develop the technology and move it to a point where its costs are low enough for widespread use.

    Full Text Available With rapid urbanization and infrastructure investment, wastewater treatment plants (WWTPs in Chinese cities are putting increased pressure on energy consumption and exacerbating greenhouse gas (GHG emissions. A carbon footprint is provided as a tool to quantify the life cycle GHG emissions and identify opportunities to reduce climate change impacts. This study examined three mainstream wastewater treatment technologies: Anaerobic–Anoxic–Oxic (A–A–O, Sequencing Batch Reactor (SBR and Oxygen Ditch, considering four different sludge treatment alternatives for small-to-medium-sized WWTPs. Following the life cycle approach, process design data and emission factors were used by the model to calculate the carbon footprint. Results found that direct emissions of CO2 and N2O, and indirect emissions of electricity use, are significant contributors to the carbon footprint. Although sludge anaerobic digestion and biogas recovery could significantly contribute to emission reduction, it was less beneficial for Oxygen Ditch than the other two treatment technologies due to its low sludge production. The influence of choosing “high risk” or “low risk” N2O emission factors on the carbon footprint was also investigated in this study. Oxygen Ditch was assessed as “low risk” of N2O emissions while SBR was “high risk”. The carbon footprint of A–A–O with sludge anaerobic digestion and energy recovery was more resilient to changes of N2O emission factors and control of N2O emissions, though process design parameters (i.e., effluent total nitrogen (TN concentration, mixed-liquor recycle (MLR rates and solids retention time (SRT and operation conditions (i.e., nitrite concentration are critical for reducing carbon footprint of SBR. Analyses of carbon footprints suggested that aerobic treatment of sludge not only favors the generation of large amounts of CO2, but also the emissions of N2O, so the rationale of reducing aerobic treatment and

    In an effort to achieve the objectives, the following provisions were made. First of all, the current status of energy industry was carefully reviewed. An increase of energy consumption, both in industrial and home purposes, implored introduction of nuclear power as an alternative energy production source. Secondly, the current status of China's nuclear development programs together with future prospects was reviewed. Through this review, more effective implementation of nuclear cooperative programs could be devised. Thirdly, China's newly developed nuclear infrastructure was analyzed. The re-structuring of the CNNC was reviewed. Based on this analysis, future cooperative programs could be identified. Lastly, proper strategies for future cooperation between the two countries on a complementary basis were studied. Recommendations for better cooperation programs, particularly for the nuclear policy-making process, were presented. For fruitful cooperation, it is naturally needed match funds to support the implementation of joint projects. It is basically China's idea that Korea provides the funds and China provides manpower. China has a great potential market. The Korean Governments support for key funds for cooperative programs will thus have a sincere meaning.

    Banana is the worldwide 2nd fruit with the biggest trade,it is also the only one of top five fruits with trade deficit compared with the other four, like apple, citrus, pear and peach, having great contributions to fruits export business in China. The import quantity of banana is continuing to rise even as the increasing production recent years, meanwhile the loss of banana in its producing area is approaching one million, almost two times of its export quantity in China, which suggests that loss reduction will contribute to shrink the trade deficit. Based on the statistics, more than 700 projects about banana research were approved by the Chinese governments and almost 500 scientific research institutions and universities were involved. However, few of them were about loss reduction in producing areas. Further researches about the exiting preliminary processing technologies may reduce banana loss in its producing area, then trying a new way to break through the bottleneck problem of banana industries and improve banana industry in China. This study has collected all harvesting, plantation transportation, commercialization, storage and transport technologies used currently in banana producing area, do further classification for all those preliminary processing technologies, and integrated four principal technology chains, then gave more information about the current Chinese banana production industry. Compared with other well-developed banana producers in the world, the gaps about large-scale production, market internationalization, technology integration, equipment serialization, facilities supporting and logistics professionalization of Chinese banana production industry are still obvious, which directly induced Chinese banana products showing no international competitiveness, no high-end brands, and only sharing the lower and middle markets. However, large-scale banana plantations are not fully accords with the retails-dominated condition in China, and it is

    The demand to use information and communications technology (ICT) in education and research has grown fast among researchers and educators working in global health. However, access to ICT resources and the capacity to use them in global health research remains limited among developing country faculty members. In order to address the global health needs and to design an ICT-related training course, we herein explored the Chinese health science faculty members' perceptions and learning needs for ICT use. Nine focus groups discussions (FGDs) were conducted during December 2015 to March 2016, involving 63 faculty members working in areas of health sciences from six universities in China. All FGDs were audio recorded and analysed thematically. The findings suggest that the understandings of ICT were not clear among many researchers; some thought that the concept of ICT was too wide and ambiguous. Most participants were able to cite examples of ICT application in their research and teaching activities. Positive attitudes and high needs of ICT use and training were common among most participants. Recommendations for ICT training included customised training programmes focusing on a specific specialty, maintaining a balance between theories and practical applications, more emphasis on the application of ICT, and skills in finding the required information from the bulk information available in the internet. Suggestions regarding the format and offering of training included short training programmes, flexible timing, lectures with practicum opportunities, and free of charge or with very minimal cost to the participants. Two participants suggested the linking of ICT-related training courses with faculty members' year-end assessment and promotion. This study among health sciences faculty members in China demonstrated a high level of need and interest in learning about ICT use in research and training. The results have important implications for the design and implementation of

    The printed circuit boards basis of electronic equipment have seen a rapid growth in recent years and played a significant role in modern life. Nowadays, the fact that electronic devices upgrade quickly necessitates a proper management of waste printed circuit boards. Non-destructive desoldering of waste printed circuit boards becomes the first and the most crucial step towards recycling electronic components. Owing to the diversity of materials and components, the separation process is difficult, which results in complex and expensive recovery of precious materials and electronic components from waste printed circuit boards. To cope with this problem, we proposed an innovative approach integrating Theory of Inventive Problem Solving (TRIZ) evolution theory and technology maturity mapping system to forecast the evolution trends of desoldering technology of waste printed circuit boards. This approach can be applied to analyse the technology evolution, as well as desoldering technology evolution, then research and development strategy and evolution laws can be recommended. As an example, the maturity of desoldering technology is analysed with a technology maturity mapping system model. What is more, desoldering methods in different stages are analysed and compared. According to the analysis, the technological evolution trends are predicted to be 'the law of energy conductivity' and 'increasing the degree of idealisation'. And the potential technology and evolutionary state of waste printed circuit boards are predicted, offering reference for future waste printed circuit boards recycling.

    2013-01-01

    Full Text Available This study evaluates ecological vulnerability of the wood-grass ecotone of northeast China integrating the spatial analysis technology with algorithms. An assessment model of ecological vulnerability is developed applying the Analytical Hierarchy Process. The composite evaluation index system is established on the basis of the analysis of contemporary status and potential problems in the study area. By the application of the evaluation model, ecological vulnerability index is calculated between 1990 and 2005. The results show that ecological vulnerability was mostly at a medium level in the study area, however the ecological quality was deteriorating.

  19. Effects of Low-Carbon Technologies and End-Use Electrification on Energy-Related Greenhouse Gases Mitigation in China by 2050

    Directory of Open Access Journals (Sweden)

    Zheng Guo

    2015-07-01

    Full Text Available Greenhouse gas emissions in China have been increasing in line with its energy consumption and economic growth. Major means for energy-related greenhouse gases mitigation in the foreseeable future are transition to less carbon intensive energy supplies and structural changes in energy consumption. In this paper, a bottom-up model is built to examine typical projected scenarios for energy supply and demand, with which trends of energy-related carbon dioxide emissions by 2050 can be analyzed. Results show that low-carbon technologies remain essential contributors to reducing emissions and altering emissions trends up to 2050. By pushing the limit of current practicality, emissions reduction can reach 20 to 28 percent and the advent of carbon peaking could shift from 2040 to 2030. In addition, the effect of electrification at end-use sectors is studied. Results show that electrifying transport could reduce emissions and bring the advent of carbon peaking forward, but the effect is less significant compared with low-carbon technologies. Moreover, it implies the importance of decarbonizing power supply before electrifying end-use sectors.

    Chow, Christina M.

    Maintaining a competitive edge within the 21st century is dependent on the cultivation of human capital, producing qualified and innovative employees capable of competing within the new global marketplace. Technological advancements in communications technology as well as large scale, infrastructure development has led to a leveled playing field where students in the U.S. will ultimately be competing for jobs with not only local, but also international, peers. Thus, the ability to understand and learn from our global competitors, starting with the examination of innovative education systems and best practice strategies, is tantamount to the economic development, and ultimate survival, of the U.S. as a whole. The purpose of this study was to investigate the current state of science, technology, engineering and mathematics (STEM) education and workforce pipelines in the U.S., China, and Taiwan. Two broad research questions examined STEM workforce production in terms of a) structural differences in primary and secondary school systems, including analysis of minimum high school graduation requirements and assessments as well as b) organizational differences in tertiary education and trends in STEM undergraduate and graduate degrees awarded in each region of interest. While each of the systems studied had their relative strengths and weaknesses, each of the Asian economies studied had valuable insights that can be categorized broadly in terms of STEM capacity, STEM interest and a greater understanding of global prospects that led to heightened STEM awareness. In China and Taiwan, STEM capacity was built via both traditional and vocational school systems. Focused and structured curriculum during the primary and early secondary school years built solid mathematics and science skills that translated into higher performance on international assessments and competitions. Differentiated secondary school options, including vocational high school and technical colleges and

    In this study, we performed a pilot-scale evaluation of the enological characteristics of indigenous Saccharomyces cerevisiae strains associated with Msalais, a traditional Chinese wine produced by a unique technology of boiling grape juice prior to spontaneous fermentation. Technical and sensory characteristics of top ten indigenous strains previously identified by us by screening a collection of 436 indigenous S. cerevisiae strains (Zhu et al. 2016) were assayed in a traditional craft workshop (TCW) and a modern plant (MP). The use of these strains reduced the spontaneous fermentation (Spo F) period by 6-15 days, and resulted in higher sugar and lower alcohol content in TCW Msalais than in MP Msalais. Sensory scores of Msalais fermented by the ten strains were higher than those of wine produced with a commercial strain cy3079, varying in TCW fermentations and significantly different from Spo F, but homogenous for all MP fermentations. Four strains were extensively screened for use in industrial Msalais production. We conclude that modern technology homogenizes enological traits of indigenous strains while traditional craftsmanship maintains their enological diversity. Some strains domesticated in the course of both processes are suitable for industrial Msalais production.

    Transnational agrobiological companies have been seeking technological measures, which replace other law measures,to protect its intellectual property right in the field of transgenie technology of erops. Therefore, Genetic Use Restriction Technologies(GURTs) have beeh established later; these technologies are becoming an excessive mode of intellectual property right proteetion now by its special meehnism of occupation. However,GURTs had been hauled into the whirlpool of debate after one of GURTs was awarded patent for the first time. The facts show that transnatlonal agro-biological eompanies do not ease its research on GURTs and also do not slow down its commercial production in the teehnologies in order to safeguard their own benefit. China has also to face this facts in the future. GURTs' developing prospects in China is strenuously discussed based on its impacts on agricultural development, and it is deemed that the research and spread of GURTs might increase agricultural preduetion efficiency and give a new way to protect intellectual property fight of transgenie technology for Chia. Moreover, the bigger power in R&D of transgenic technology and the higher aeeeptance level to the GMFs in China would be of benefit to its extension and ex- ploitation, while, the actions of farmers' reserving feeds will only have a limited impact. The conclusions are that on the one hand, Chinese government should play for safety before the potential impacts of GURTs draw a definitive conclusion, on the other hand, China might allow its import of the safer T - GURTs in order to go with the current and based on the principle of seeking advantages and avoiding disadvantages;and the last, some advices are given.%在农作物转基因技术知识产权领域,跨国农业生物公司一直在寻求超越法律保护的技术措施来保护自身的知识产权,基因利用限制技术由此而产生,并通过其独特的占有机制,成为一种极端的转基因

    Full Text Available Water shortage and water pollution are important factors restricting sustainable social and economic development. As a typical coal resource-exhausted city and a node city of the South-to-North Water Transfer East Route Project in China, Zaozhuang City’s water resources management faces multiple constraints such as transformation of economic development, restriction of groundwater exploitation, and improvement of water environment. In this paper, we develop a linear optimization model by input–output analysis to study water resources management with the introduction of three advanced sewage treatment technologies for pollutant treatment and reclaimed water production. The simulation results showed that from 2014 to 2020, Zaozhuang City will realize an annual GDP growth rate of 7.1% with an annual chemical oxygen demand (COD emissions reduction rate of 5.5%. The proportion of primary industry, secondary industry, and tertiary industry would be adjusted to 5.6%, 40.8%, and 53.6%, respectively. The amount of reclaimed water supply could be increased by 91% and groundwater supply could be decreased by 6%. Based on the simulation, this model proposes a scientific reference on water resources management policies, including water environment control, water supply plan, and financial subsidy, to realize the sustainable development of economy and water resources usage.

    literature about the research of environmental technology innovation in China lacks evidence of econometrics, especially the research and the analysis about the government' s environmental policy effect. So the target of the policy is not strong. This study focuses on industrial enterprise in China taking environmental technology innovation, and uses patent applications in industrial environmental technology to measure the level of environmental technology innovation of industrial enterprises. On the basis of the unit root test and Hausman test of panel data from 2006 to 2013 in China' s 30 provinces, a fixed effects panel data model is constructed. This paper discusses the factors of environmental policy, environmental regulation intensity, the technical innovation investment and others impact on environmental technology innovation of industrial enterprises of China. The research results show that the lag of industrial pollution control investment of one year for each additional 1%, environmental technology innovation of industrial enterprises increased by 6. 45%, indicating that the environmental policies of China, namely the investment of improving the environment has a significant role in promoting the environmental technology innovation of industrial enterprises;at the same time the incentive has a certain lag. The per unit of pollution emissions of the industrial production has negative correlation with the number of patent applications of environmental technology, showing that the government increasing the intensity of environmental regulation is helpful to stimulate enterprises to increase supply of environmental technology innovation. In addition, the technology investment of industrial enterprises, the demand of market, the international technology spillover effect and the industry scale of industrial enterprises all have positive correlation with enterprise' s environmental technology innovation. Among them, the technology investment of industrial enterprise is

    近年来,我国工业行业技能劳动力的需求快速增加,技能供需矛盾日益突出.虽然有文献认为技能偏向型技术变化是其中的重要原因,但是对技能偏向型技术变化存在性的规范检验几乎一片空白.本文基于经典文献提供的实证方法,以工业全行业和大中型行业为实证对象,规范检验20世纪90年代以来我国工业技术进步的技能偏向性.首先,对技能劳动力就业份额变化进行分解的结果表明,我国工业就业结构技能升级的主导因素是细分行业内而不是细分行业之间技能劳动力就业份额的变化.其次,基于我国工业经济的特性,计量检验了技术进步、对外开放和资本-技能互补性等因素对工业就业结构技能升级的影响,揭示了技术进步与技能劳动力就业份额之间显著的正相关关系.这两方面的结果验证了20世纪90年代以来我国工业行业的技能偏向型技术变化,并为技能劳动力短缺提供了基于需求角度的解释.%The relative demand for skilled labors has been increasing rapidly in China' s industry in recent years. Many papers attributed it to the skill-biased technological change, but the empirical test on the existence of the skill-biased technological change of China' s industry has still lacked. Based on the micro data on all industrial and large-and-medium industrial enterprises, utilizing some empirical approaches provided by classical literature, the technological progress of China' s industry that is characterized by skill bias since 1990 is tested in this paper. Firstly, changes in share of skilled labor in industry since 1990 is decomposed into "within industry" shifts and "between industries" shifts, and the results show that increasing upgrading of industrial employment can be largely explained by "within industry" shifts, not by "between industry" shifts. To further investigate the causes of these shifts, changes in share of skilled labor are

  20. Comprehensive evaluation technology for shale gas sweet spots in the complex marine mountains, South China: A case study from Zhaotong national shale gas demonstration zone

    Directory of Open Access Journals (Sweden)

    Xing Liang

    2016-01-01

    Full Text Available The exploration and development of marine shale gas reservoirs in South China is challenged by complex geological and geographical conditions, such as strong transformation, post maturity, complex mountains and humanity. In this paper, the evaluations on shale gas sweet spots conducted in Zhaotong demonstration zone in the past six years and the construction of 500 million m3 shale gas productivity in Huangjinba region were discussed, and the results of shale gas reservoir evaluations in China and abroad were investigated. Accordingly, it is proposed that another two key indicators be taken into consideration in the evaluation on shale gas sweet spots in marine mountains in South China, i.e. shale gas preservation conditions and pore pressure, and the research on ground stress and natural microfracture systems should be strengthened. Then, systematic analysis was conducted by integrating shale gas multidisciplinary data and geological and engineering integration study was carried out. Finally, a 3D model, which was composed of “geophysics, reservoir geology, fracture system and rock geomechanics”, was established for shale gas reservoirs. Application practice shows that the geological engineering integration and the 3D reservoir modeling are effective methods for evaluating the shale gas sweet spots in complex marine mountains in South China. Besides, based on shale gas sweet spot evaluation, 3D spatial congruency and superposition effects of multiple attributes and multiple evaluation parameters are presented. Moreover, the short-plate principle is the factor controlling the distribution patterns and evaluation results of shale gas sweet spots. It is concluded that this comprehensive evaluation method is innovative and effective in avoiding complex geological and engineering risks, so it is of guiding significance in exploration and development of marine shale gas in South China.

    It's an important way to gain foreign advanced technology by the introduction of FDI. From the time reformation and opening policy carried out to year 2008, it has attracted quantities of foreign investments through " super-national treatment" , but not much emphasis laid on quality. This caused the technology level of imported FDI far below expectations. Since the completeness of two tax integration , technology threshold has been enhanced for FDI to gain tax incentives. It expects that imported FDI could then reform from valuing only quantity to valuing quality more, and finally brings in higher level of imported inherent technology. This paper will make a comparative analysis to the change of FDI technology level before and after two tax integration in China, and then propose further income tax incentive policies so as to attract more FDI with high technology level in the context of new income tax global competition nowadays.%引进FDI是获得国外先进技术的重要途径,从改革开放到2008年,我国以对FDI的“超国民待遇”吸引了大量的外资,但重量不重质,引进FDI的技术水平远低于预期.“两税合并”以后,我国提高了FDI获得税收优惠的技术门槛,希望引进的FDI能够从重量转变为重质,提高引进FDI的内含技术水平.本文通过具体数据对比分析了我国“两税合并”前后FDI技术水平的变化,并在新的所得税竞争的国际背景下,提出进一步吸引更多高技术水平FDI的所得税优惠政策.

    According to the new economic growth theory, a novel method of computing contribution rate of science and technology progress based on C-D production function and Solow method were proposed in this paper. Three steps of the method are as follows:First, perform fuzzy soft clustering of 31 Chinese provinces, autonomous regions and municipalities to obtain the degree of membership of these places belonging to each category, according to the level of science and technology improvement. Second, calculate the contribution rate of science and technology progress of different technology level categories in respect to economic growth. Third,multiply the obtained contribution rate of each category by degree of membership that the region belongs to so to obtain the contribution rate of science and technology progress in each region. Finally, this method was employed to calculate the contribution rate of science and technology progress in 31 Chinese provinces (cities) from 1998 to 2007. Results showed that level of science and technology development was unbalanced in China, where Shanghai got the highest contribution rate of science and technology progress of 54.19%,followed by Beijing with 48.90%, and Sichuan being the last with 28.59%. In addition, the economic growth of Chinese regions depended mainly on funding, whose contribution rate was up to 60%. Therefore, China needs to pay attention to the development level of science and technology, and give full play to the role of science and technology progress in economic growth, so as to give an impetus to the improvement of contribution rate of other production factors and boost the overall economic growth.%依据新经济增长理论,提出了一种基于C-D生产函数和索罗余值法测算科技进步对经济增长贡献率的新方法.该方法包括三个步骤:首先,对中国31个省市按照科技进步水平进行软分类.得到各地区隶属于各类别的隶属度;第二,分别计算不同科技水平
