[ScienceDirect, via Biblio-SHS] Auteur : Adolf K.Y. Ng, James J. Wang Paru dans : Research in Transportation Economics, Volume 35, Issue 1, Pages 1-66 (May 2012) Editorial 1. Introduction Globalization has brought China ever close to the rest of the world not only through its trade and transport networks, but also many transport-related issues that seem to be in common among other countries, while simultaneously with special causes deep-rooted from its unique pathway of development especially in the past several decades. The major fundamental difference of China's development from other countries lies in its economy in general, while the transport sector, in particular, lies in the role of the government. Indeed, since the global financial crisis in 2008, advanced economies, such as the US and several EU countries, have intensified on how to redefine and strengthen the role of the state within respective economies. On the contrary, the Chinese situation is exactly the other way round: the debate is about how to reduce interferences from the very strong hands of the government towards a real regulated market. In this respect, the transport sector typifies this ongoing marketization process. On one extreme, the mode of highway transportation is fully marketized: private investors may construct toll expressways in almost any provinces, either as joint ventures partnering with state-owned firms or just as fully private developers. On the other side of the continuum, after more than three decades of 'reforms', railway infrastructures, as well as their operation, are still fully and tightly controlled by the Ministry of Railways (MOR) through its subsidiary's monopoly. In-between the highways and railways are air and maritime transportation, both of which being characterized by oligopolies with two to three state-owned listed companies taking up more than 80% of the market share. Given such situation, there is a clear interest for further understanding and re

Abstract Taking Beijing as a case study, this paper analyses new trends in peri-urbanisation and the city's planning responses after 2000 in China. The results of the analysis show that the percentage of temporary migrant residents continues to grow in the peri-urban region and the social inequalities in relation to quality of life between local people and migrants have increased there. In particular, there is a concentration of thousands of young and well-educated migrants in the peri-urban region, resulting in a new kind of urban slum. Sprawling development still dominates Beijing's fringe. New planning policies related to an urban-rural integration strategy have played a positive role in improving living conditions in rural areas and reducing the social and economic gaps between urban and rural areas in the peri-urban region. However, planning in the peri-urban region is still facing new challenges due to vertically and horizontally fragmented management, growing market forces, and social discrimination caused by the remnants of the hukou mechanism. This suggests that it will not be easy to achieve the planning goal of urban-rural integration and harmony society unless further actions are taken to enhance political capacity of planning system in Beijing. The capacity-building of planning should be facilitated if institutional innovations can be made in arrangements of power, rights, public resources, accountability, and legitimacy in the planning system. Highlights ► Many new trends in peri-urbanisation have appeared after 2000 in Beijing. ► Peri-urbanisation contributes to growth in social inequalities. ► It will not be easy to achieve the planning goal of urban-rural integration. ► New urban-rural integration policies are facing challenges. ► The institutional capacity of planning needs to be reinforced.

On the basis of the concept and connotation of Chinese urbanization defined by Chinese scholars, the paper systematically collects the research results on the issues concerning urbanization in China from the different approaches of demography, geography, city planning, economics and history, reviewing the process of research on Chinese urbanization made both domestically and internationally. In this paper, the domestic studies fall into five periods as follows: the initial period of research on urbanization in China (1978-1983); the period with both domestically constructed and borrowed theories on urbanization (1984-1988); the period of research on leading urbanization factors and localization (1989-1997); the period with the research greatly promoted by the government (1998-2004); and the period featuring flourishing studies on the science of urbanization in China (2005 till today). In contrast, the overseas research on Chinese urbanization can be divided into three periods: the period studying the history of urbanization in China (before the 1970s); the systematic research on Chinese urbanization (1970-1999); and the comprehensive research on Chinese urbanization (2000 till today). The paper focuses on the key results of research on Chinese urbanization, including nine issues as follows: the guidelines and road for urban development in China, the features of Chinese urbanization, the mechanism driving the growth of Chinese urbanization, the process of Chinese urbanization, the spatial patterns of Chinese urbanization, the urbanization in rural areas in China, the comparison of urbanization in China and other co

Abstract In 2011, China announced that it has reached an urbanisation rate of 50%. If we take rapid urbanisation as a given and that it is already well underway, it is still widely unclear what research needs to be conducted and policy changes made to support municipalities of fast transforming cities and to avoid repeating the development mistakes that have occurred in industrialised nations, i.e. driving urban growth with high consumption patterns without fully considering the environmental and social needs and occupants' behaviour and aspirations. The scale and pace of change requires a solid systems approach of urban development. The purpose of this paper is to explore the rapid urbanisation of Chinese cities with a focus on the plans for a new, on-going urban sub-centre in the north-west of Shanghai: Zhenru urban sub-centre. Information-rich urbanisation is a defining feature of the 21st century, reshaping cities and communities in China and in developing countries around the world. The paper compares two cases of urban development patterns for new sub-centres for polycentric city structures: it relates to new urban sub-centres in Berlin (Germany) and Shanghai (China), and the relationship of these sub-centres to 'Network City' theory. Network theory is useful in this context as the 'network' metaphor and concepts of decentralisation seem to have replaced the 'machine' metaphor which was based on efficiency based on the availability of cheap fossil fuels. The question to be addressed is how Chinese cities can be better steered towards more sustainable models of development. As cities aim to move towards more resilient urban ecosystems and polycentric systems, the case of Potsdamer Platz Berlin, compared to Zhenru sub-centre in Shanghai, is discussed. Both are transport-oriented developments promoting mixed-use density and less car-dependency. According to documentation of the Shanghai municipality, Zhenru urban centre, which is currently

Zhang Chun Wang Haotong August 03, 2012 China's low-carbon city programmes are doing well on public awareness, but an NGO survey finds little evidence of greener habits. Only a small proportion of people in China's low-carbon pilot cities are living "low-carbon lives" in spite of widespread knowledge of the green agenda, a year-long survey of household energy consumption carried out by Beijing-based NGO Green Beagle suggests. The study of habits in eight Chinese cities identified as green leaders by China's top economic planning body, the National Development and Reform Commission, involved 3,200 questionnaires and interviews with three to five households in different income brackets in each region. The NGO wanted to find out if inhabitants of these places had heard about "low-carbon" lifestyles and whether they were making efforts to reduce their own environmental footprint through their daily choices. Under the "low-carbon" pilot scheme, which launched in 2010, the eight cities - Tianjin, Chongqing, Shenzhen, Xiamen, Hangzhou, Nanchang, Guiyang and Baoding - are trying to find ways of reducing carbon emissions while continuing to grow economically (Beijing and Shanghai were added to the list in 2011, but are treated as a separate category). Five provinces are charged with the same task: Guangdong, Liaoning, Hubei, Shanxi and Yunnan. If they perform well, they will be treated as an example for the rest of the country.[...]

Abstract This paper links urbanization strategies to changes in land use and associated impacts on rural communities and agro-ecosystems in a rural area of China. Energy, monetary and human time variables as well as information on environmental pressures, have been combined to compare different typologies of households and the metabolism of different patterns of land use from an integrated perspective. The results show that urbanization strategies, aimed at shifting the current land use and at displacing the local population, while increasing the economic efficiency is also associated with an increase in fossil energy consumption and environmental pressure, as well as a reduction of the multifunctional characteristic of the area under investigation. Based on these findings the paper also offers a critical discussion of the Chinese rural development policy arguing that the multifunctionality of rural areas should be taken into account by Chinese policy-makers and planners as a viable strategy to achieve rural development targets. Highlights ► Urbanization strategies in China drive the land use change of rural areas. ► Forced migration decreases rural food self-sufficiency and diversification of risk. ► HEPA patterns have higher economic efficiency and energy intensity than LEPA. ► Rural-urban migrations favor the creation of mono-functional agricultural systems.

Sur le site "The Urban China Initiaitve" 4/05/2012 By Li Jing ( China Daily) Urban leaders do more to safeguard environment, conserve resources Small and medium-sized cities are more livable than big cities such as Beijing and Shanghai gauged by their air quality, waste treatment capacity and built environment, according to newly published research by Urban China Initiative. A woman rides a bicycle on a windy day in Beijing. According to recently published research by Urban China Initiative, Beijing and Shanghai were absent from a ranking of the top 10 Chinese cities gauged by their environmental sustainability. [Photo/China Daily] UCI, a think tank launched by Tsinghua University, McKinsey & Co and Columbia University, gauged the sustainability of 112 major Chinese cities using 17 indicators in four categories - society, economy, environment and resources. Beijing ranked first in sustainability thanks to its heavy investment in social welfare - including social security, education and healthcare - and its economic achievements. The top 10 cities in overall score - including Xiamen, Fujian province, Haikou, the capital of Hainan province, Dalian in Liaoning province, and Shanghai - are all medium and large-sized cities. However, small and medium-sized cities are taking the lead in environmental sustainability. Both Beijing and Shanghai were absent from the top 10 in this category. According to the research, Haikou has the best air quality, while Hefei, capital of Anhui province, took the lead in waste treatment facilities. And Xining, the capital of Qinghai province, boasts the best built environment - man-made surroundings that serve as the setting for human activity. "Such a result shows that small cities have a better quality of life, though people living in megacities like Beijing and Shanghai have better access to medical and educational resources," said Jonathan Woetzel, co-chair of UCI, as well as a senior global dir

Xuefei Ren's work on the high-end of the building boom in China brings together the sociology of globalization with the study of architecture and the built environment. Building Globalization treats architectural production as crucial to the material and symbolic ways in which global cities are made. Based on Ren's doctoral research at the University of Chicago, the book draws on fieldwork conducted in Beijing and Shanghai between 2004 and 2008, covering the bull years leading up to the Beijing Olympics. China is now taken to exemplify the geo-demographic shift that has seen developing countries lead current processes of urbanisation. However the Chinese government's attitude towards quanqiuhua chengshi (global cities) and its support for rapid urban growth from the mid-late 1990s represented a striking reversal of official policy which had been to limit the growth of large cities and promote instead the development of small-medium centres (p.11). The re-scaling of state power to metropolitan level in the interests of enhancing urban competitiveness has been an international trend in recent decades. In China this has proved particularly effective in driving urban growth, given state ownership of land and government control over household registration, urban planning and development decisions. Metropolitan governments in China have the kind of ownership and discretionary powers of which the most boosterist western city mayors can only dream. Ren argues convincingly that the processes shaping these cities are increasingly transnational; in particular, the forces that make buildings 'operate beyond national boundaries, as seen in the circulation of investment capital, the movements of built-environment professionals, and the diffusion of new technologies' (p.6). However, while Chinese economic growth may have destabilized a global balance of power dominated by the triad of the USA, the European Union and Japan, Ren's analysis suggests that older core-peripher

Centre for Sustainable Energy Technologies, The University of Nottingham Ningbo China 27th to 28th October 2012 Ningbo, Zhejiang, China The building sector is one of the highest energy consuming sectors in China accounting for about 30% of total energy usage and also contributes to a significant proportion of pollutant emissions in China. Meanwhile, building construction activities are contributing significantly towards China's economic growth and infrastructure development under the current urbanisation programme. It is estimated that half of the world's buildings being constructed between now and 2020 are expected to be built in China and if nothing is done to control the upward energy trend, building-related energy consumption could double and have a devastating effect on the environment and the economy as a whole. The objective of this international symposium is therefore to provide a forum for academics, government officials, researchers and practitioners to present and discuss recent research and demonstration projects related to low carbon buildings in China. The event will feature well known international experts in this field as Keynote speakers. General topic areas * Sustainable Energy Technologies * Energy storage technologies * Energy and Environmental Policy * Modelling and simulation of buildings * Thermal Energy Management systems * Low carbon construction materials * Eco-building design * Integration of renewable energy technologies in refurbished buildings * Life cycle analysis of low carbon buildings * Waste and water management * Energy Management Contract systems * Post occupancy evaluation of low carbon buildings * Green Architecture * Design for low impact healthcare buildings * Improving sustainability (and resilience) of healthcare facility * Sustainable Urbanism * Urban form and Energy use or Low carbon cities * Green and liveable cities Website: http://www.nottingh

Hoversten, Shanna, "Electric Vehicles: Market Opportunities in China" (2010). CMC Senior Theses. Paper 1. http://scholarship.claremont.edu/cmc_theses/1 Abstract Electric vehicles (EVs) offer an exciting opportunity in China both in terms of the potential to build a domestic manufacturing base and the potential to create a strong domestic market for the product. The Chinese nation stands to benefit from both supply-side and demand-side promotion due to the economic stimulus from EV manufacturing and export, the environmental benefits of reduced air pollution and reduced greenhouse gas emissions, and the energy security benefits of transitioning away from foreign oil dependence. The Chinese have several advantages when it comes to stimulating EV industry development and EV deployment, including: leadership in battery technology, great potential for cost competitiveness, an enormous and emerging number of new car buyers, and high level government support. Yet a number of challenges must be taken into account as well, including: shortfalls in overall automobile R&D spending, consumer concerns about Chinese cars' safety and reliability, enhancing the appeal of the Chinese brand, and heavy national infrastructure demands. This paper will seek to examine the opportunities and challenges associated with EV deployment in China and identify industry actions and policy measures to facilitate the process.

We find that people feel unhappy with between-group inequality, as measured by the income gap between migrants without local urban hukou (household registration identity) and urban residents, irrespective of whether they are urban residents with or without local hukou. However, when we control for identity-related inequality and other individual, household, and city-level characteristics, inequality (as measured by city-level Gini coefficients) positively correlates with happiness. This study contributes to the inequality-happiness literature by distinguishing between the different effects of between-group and general inequality on happiness.

Paru dans : Land Use Policy, Volume 29, Issue 4, October 2012, Pages 737-749 Abstract China has extremely scarce land resources compared to the world average. There is an urgent need for studies of the current situation and the trends in land-use change and assessment of the performance of land policies in China. Assessment of land-use change has long been hindered by a lack of accurate and reliable data. This paper uses the data obtained from the national land surveys of 1996 and land-use change surveys from 1997 to 2008, to analyze changes in land use and the policy dimension driving forces related to the changes, especially cultivated land, forestry land, grassland, as well as developed land. The aim of this analysis will be to derive the physical, social and economical driving forces of those changes to grasp the trends in land-use change and the effects of land policies and to formulate strategies for the protection and sustainable use of agricultural land. The results indicate that, although the overall change in land use was not large, cultivated land was significantly reduced and developed land rapidly increased. A great deal of high quality cultivated land was changed to developed land and low quality cultivated land generated from unused land, which has resulted in a serious threat to food supplies in China. Predictions using the methods of linear extrapolation and a BP neural network indicate that it is impossible to keep to a target of 0.12 billion hectares of cultivated land in the future under the mode of economic development used between 1996 and 2008. The results also indicate that the implementation of the laws and regulations about controlling the developed land and preserving cultivated land had significant effects on changes in land use, especially cultivated land and developed land. The results sugges

Ma Paru dans : Cities, Volume 29, Issue 2, April 2012, Pages 107-117 Abstract China's rapid growth over the last three decades has attracted much academic attention. In the post-reform era, economic growth has been paralleled by rapid urbanization. China's urbanization experience has been shaped heavily by the state through national urban policies as well as through local administrative means. Much has been written about large Chinese cities in the more developed coastal regions, such as Beijing, Shanghai and Guangzhou, but little is known about the process of city-making in medium-sized and small Chinese cities, especially those in the less developed central and western regions of the country. This paper sheds light on the processes of urban transformation in Hebi, a medium-sized inland city in Henan Province, emphasizing the critical role that the local state has played in city-making, the mechanisms and processes of change, and the resultant impacts on the city. As a mining city, Hebi has been threatened by depleting natural resources. To invigorate the city, a new city center has been built to attract new enterprises. Through intensive interviews and fieldwork conducted in 2007 and 2008, we examine what the city government of Hebi has done to turn the newly constructed urban space into a new administrative and economic center of the city. With the establishment of new enterprises, the local economy has been diversified, although coal continues to be a major component of Hebi's economy. The role of the local state in the production and development of the new urban space is direct and forceful. As local state policies on urban development have been implemented by strong administrative means, we conceptualize the contemporary Chinese model of urbanization as "administrative urbanization".

Abstract We performed a bibliometric analysis of published urbanization research from 1991 to 2009, based on SCI and SSCI database. Our analysis reveals scientific outputs, subject categories and major journals, international collaboration and geographic distribution, and temporal trends in keywords usage in urbanization studies and discusses the relationships between urbanization papers and urbanization rate and offer a substitute demonstration of research advancements, which may be considered as a potential guide for future research. The growth of article outputs has exploded since 1991, along with an increasing collaboration index, references and citations. Environmental sciences, ecology, environmental studies, geography and urban studies were most frequently used subject categories and Landscape and Urban Planning was the most productive journal in urbanization studies. The United States was the largest contributor in global urbanization research, as the USA produced the most independent and collaborative papers. The geographic distribution of urbanization articles overlapped quite well with regions with high economic growth in North America, Europe, and Pacific-Asia. A keywords analysis found the USA and China were "hotspots", confirmed land-use's significant position and revealed keen interest in ecological and environmental issues in urbanization studies. In general, urbanization research was strongly correlated with the urbanization rate although there were different patterns and underlying processes across different countries. This is the first study to quantify global research trends in urbanization. Our study reveals patterns in scientific outputs and academic collaborations and serves as an alternative way of revealing global research trends in urbanization.

Thématique 2 [ScienceDirect, via Biblio-SHS] Auteur : Thomas Vendryes Paru dans : China Economic Review Volume 22, Issue 4, December 2011, Pages 669-692 Sustainable natural resource use in rural China - Has China Passed the Lewis Turning Point? CERDI 2009 - CERDI 2009 Abstract Rural-urban migration flows are a crucial corollary of economic development. The adverse or beneficial effects of internal migration, for sending as well as receiving areas, and the definition of optimal migration policies, have remained much discussed issues since the seminal works of Harris and Todaro (1970). This debate is especially acute in China where the "household registration system" (hukou) acts as a strong constraint on individual migration. This paper aims to assess the consequences of hukou through a simple model of a developing dual economy with overlapping generations. Contrary to existing studies focused on the contemporaneous allocation of economic resources, it deals with the dynamic consequences of migration flows and migration policies. It shows that, in fairly general circumstances, hukou-related migration constraints can actually hasten development, understood as the transfer of the labor force to the modern sector, driven by capital accumulation. The hukou system could thus be one of the causes of the extremely high Chinese saving rate and of the high pace of Chinese development. Insights from the model are confronted with stylized facts from the Chinese development, and theoretical results are especially consistent with the effects of the 2001 "towns and small cities" reform.
