Renewable and Sustainable Energy Reviews | Year: 2015

This study investigates Chinas biofuel industry-the third largest in the world-by combining a strength, weakness, opportunity and threats (SWOT) analysis with a method known as fuzzy analytic hierarchy process (FAHP). More specifically, the study employs SWOT analysis to identify the influential factors affecting the development of the biofuel industry in China. It then prioritizes their importance using the FAHP method. The study finds that high production costs, competition with other renewable energy resources, inconsistent policy and legislation support, and poor technical standards are impeding the growth of the biofuel industry of China. The study concludes by proposing strategic recommendations for how the industry can be made both leaner, more efficient and effective, and greener, more socially and environmentally sustainable. Some of these options focuses on improving technical perform, adhering to a "supply push" mentality. Others focus on improving affordability and consumer awareness, adhering to a "demand pull" mentality. © 2015 Elsevier Ltd. All rights reserved.

The impacts of a rail transit system on residential property values have been examined for many metropolitan areas in the United States, China, and other countries, yet there have been few comparison studies between countries. Studies have reported both the positive effects of rail transit resulting from improved accessibility as well as the nuisance effects from noise, pollution, crime, and unsightliness. The net effects of a rail transit system could be mixed, and there has been no agreement on which would dominate. This study used METROKail in Houston, Texas, and the Metro in Shanghai, China, as empirical cases and compared their effects on nearby residential property values. A hedonic price model w ith ordinary linear regression was used in the case study of Shanghai's rail transit lines. The Houston case study applied ordinary linear regression and multilevel regression techniques to examine the hierarchical structures of spatial data explicitly. The modeling results from both cases suggest that the overall effects of rail transit lines on residential property values are significantly positive. Notable variations of rail transit effects were also observed at various distance ranges and time spans.

Low-carbon urban development is a hot spot of global concerns for fighting against climate change for China, transportation sector has a significant contribution to urban CO2 emissions, while the emissions are still increasing. Transit-Oriented Development (TOD) strategies provide a novel approach for urban planners to facilitate the urban carbon mitigation from transportation sector in long-term. While TOD strategies are emerging cases, they are merely qualitatively discussed in China, lacking practical indicators and quantitative verification for supporting the real urban plan. With such circumstance, this study aims to conduct an empirical and quantitative study on the applications of TOD strategy in Shanghai based on Exploratory Spatial Data Analysis (ESDA) and the updating data. Firstly, the changes of urban morphology were quantitatively analyzed by spatial cluster analysis, which reveals the layer structure changes and residents migration at about 1 km accuracy. Secondly, accessibility was selected as an indicator for urban transportation and estimated by method based on Time Cost Weighted Distance. Finally, the effectiveness of TOD was investigated by evaluating the integration between population and transportation accessibility with Geographic Weighted Regression model. Results highlight that TOD can effectively improve the transportation network with higher accessibility and lower urban carbon emissions. The outcomes of this study provide critical insights to the recent practice in Shanghai, as well as the practical guidance to low carbon urban planning in developing countries. © 2015 Elsevier Ltd.

In China, although per capita energy consumption is lower in the urban rail transit system than other modes of transportation, the total energy consumption and greenhouse gas emissions will reach considerable levels based on the current speed of urban rail transit system development. The objective of this research is to use the life cycle assessment (LCA) type method to define the system boundaries of the life cycle of Shanghai Metro and to inventory the associated resource inputs and emission outputs based on actual observed data. A comparative analysis of GHG emissions of different urban rail transit systems around the world is also provided. The results show that the total life-cycle GHG emissions per construction length of the entire Shanghai Metro are 109,642.81tCO2e (with a service life of 50 years), and materials production, materials transportation, on-site construction, operation, and maintenance generated, respectively, about 4.1%, <0.1%, 0.4%, 92.1%, and 3.4% of the total emissions. Although the traction emissions per passenger-km traveled of Shanghai Metro are competitive at the global level, there is still great energy-saving potential in the operation phase, especially in ornately designed train stations. The preliminary conclusions of this study may help shed light on the emission reduction potential of urban rail transit systems and the emission reduction targets in China and serve as a source of information and data for future LCAs. © 2016 Elsevier B.V.

Biofuel as a promising pathway for substituting the traditional fossil fuels, mitigating environmental contaminations, and enhancing the energy security has attracted more and more attention in China. This study aims at identifying the critical success factors for promoting the sustainable development of biofuel industry and helping the stakeholders/decision-makers to draft the appropriate strategic measures for enhancing the sustainability of biofuel industry in China. A generic methodology in which the decision-makers are allowed to use linguistic terms to express their views and options, multiple decision-makers are allowed to participate in the decision-making, has been developed to prioritize the factors influencing the sustainability of biofuel industry and to identify the cause-effect relationships among these factors. The three factors, including government support degree, competitiveness, and local acceptability are identified as the most critical factors for promoting the sustainable development of biofuel industry in China, but they are all effects rather than the origins of the problems existed in the biofuel industry of China. In contrast, maturity, safety and reliability, complexity, conversion efficiency, and investment cost are the most important causes, and they are also the origins of the problems existed in the biofuel industry of China. Six effective strategic measures including popularizing the use of biofuels in large scales, subsidies and tax exemption policies, investing more on R&D on biofuel technologies, encouraging more private enterprises and joint ventures to participate in the biofuel industry, developing the integrated utilization manner of biofuels by further developing the byproducts of biofuels, and popularizing the use of biodiesel and bioethanol among the vehicle users through publicity and education have been proposed for promoting the sustainable development of China's biofuel industry according to the obtained results. © 2016 Elsevier Ltd.

Renewable and Sustainable Energy Reviews | Year: 2016

China applies no efforts to promote the development of renewable energy (REE) so as to enhance China's energy security and address climate change. National top-down support scheme and the local renewable energy industry (REEI) development are the two important and intervened countermeasures for promoting REEI development in China. Considering China's vast regional disparity, the review on the spatial distribution of REEI in provincial level is critical and enlightening for future appropriate policy-making, while to date, there has been few related studies. With this circumstance, this paper made an empirical study on the distribution and cluster pattern of China's REEI based on the analysis on the industrial output value, the number and location of key companies/industrial bases, through on-site survey and updating statistical data. Results highlighted that in general, four REEI clusters were formed, included Bohai sea region, Yangtze River Delta, middle area, and western area. Supply chains were diversely distributed based on the regional resources allocation as well as economy development level and. In summary, REE resource supply and transformation facilities construction were the main REEI in western China, while R&D and high-tech equipment manufacture were clustered in eastern coastal regions. Based on the empirical study and Analytic Network Process (ANP) of the roles of stakeholders involved REEI of China, we further proposed various strategic measures and policy implications to better balance the REEI development in China. Our findings were critical for China's authority to design appropriate policies and take effective measures for promoting the harmonious development of REEI. © 2016 Elsevier Ltd.

Urban infrastructure has been substantially upgraded in reform-era China. This paper explains, contextually and empirically, how Chinese cities finance their infrastructure. It demonstrates that China has succeeded in addressing urban infrastructure backlogs by opening up new venues for financing, but simultaneously, heavily relying on unconventional sources. The paper also argues that urban infrastructure financing has much to do with the country's transition to a market-oriented economy that fosters the pro-growth role of city governments as well as the redistribution of fiscal power between the levels of the urban hierarchy that produces significant variation of financial capacities among the different administrative ranks of cities. © 2011 Urban Studies Journal Limited.

Vernacular Architecture: Towards a Sustainable Future - Proceedings of the International Conference on Vernacular Heritage, Sustainability and Earthen Architecture | Year: 2015

China vernacular architecture heritage is famous with its big quantity, abundant types and outstanding value. Due to the great disparities of economy, society and culture background between different regions of China, every vernacular architecture heritage not only has distinctive features, but also in the progress of conservation and development faces different problems. As a consequence, there is no common approach to solve all problems of different heritages. This article takes two traditional villages which are respectively located in eastern developed area and western poverty area as examples. Through value assessment and status analysis of the vernacular architecture heritages of the two villages, the authors put forward targeted solutions of protection and development of them. Further, attempt to give recommendations to the large subject of conservation and sustainable development of China vernacular architecture heritage. © 2015 Taylor & Francis Group.
