Abstract: Threatened by the huge pressure caused by climate change, low-carbon cities have become an inevitable part of urban evolution. It is essential to evaluate urban low-carbon development levels to smoothly promote the construction of low-carbon cities. This paper proposes an evaluation index system for urban low-carbon development from the points of view of economic development and social progress, energy structure and usage efficiency, living consumption, and development surroundings. A weighted sum model was also established. Selecting 12 typical Chinese cities as cases studies, an integrated evaluation was conducted based on the index system and the assessment model. The development speed and limiting factors of different cities were also analyzed. The 12 cities were ultimately classified into three groups in terms of their low-carbon development patterns by integrating all of the analysis results. Furthermore, suitable regulation and management for different patterns were suggested. This study both aids in assessing the executive effect of low-carbon city construction and helps to determine existing problems and suggest effective solutions.

" We evaluate the role that cities play on individual productivity in China. First, we show that location explains a large share of nominal wage disparities. Second, even after controlling for individual and -firms characteristics and instrumenting city characteristics, the estimated elasticity of wage with respect to employment density is about three times larger than inWestern countries. Land area and industrial specialisation also play a significant role whereas the access to external markets does not. Therefore, large agglomeration economies prevail in China and they are more localised than in Western countries. Third, we -find evidence of a large positive impact of the local share of migrants on local workers'wages. Overall, these results strongly support the productivity gains that can be expected from further migration and urbanisation in China. "

The rapid growth of the Chinese economy has resulted in great pressure on energy consumption, especially the energy intensive sector - the industrial sector. To achieve sustainable development, China has to consider how to promote energy efficiency to meet the demand of Chinese rapid economic growth, as the energy efficiency of China is relatively low. Meanwhile, the appeal of energy saving and emission reduction has been made by the Chinese central government. Therefore, it is important to evaluate the energy efficiency of industrial sector in China and to assess efficiency development probabilities. The framework of total factor energy efficiency index is adopted to determine the discrepancy of energy efficiency in Chinese industrial sector based on the provincial statistical data of industrial enterprises above designated size in 30 provinces from 2005 to 2009, with gross industrial output as the output value and energy consumption, average remaining balance of capital assets and average amount of working force as the input values. Besides, in considerate of the regional divide of China, namely eastern, central, and western, and economic development differences in each region, energy efficiency of each region is also analysed in this paper. The results show that there is room for China to improve its energy efficiency, especially western provinces which have large amount of energy input excess. Generally speaking, insufficient technological investment and fail of reaching best scale of manufacture are two factors preventing China from energy efficiency promotion. Based on our findings, some policy implications on the improvement of energy efficiency, particularly for economically underdeveloped regions in China, are also discussed.

Kahn (National Bureau of Economic Research (NBER), USA), Yongheng Deng (National University of Singapore, Singapore) Paru dans : European Economic Review Volume 56, Issue 5, July 2012, Pages 974-984, "Green Building, the Economy, and Public Policy" Abstract In recent years, formal certification programs for rating and evaluating the sustainability and energy efficiency of buildings have proliferated around the world. Developers recognize that such "green labels" differentiate products and allow them to charge a price premium. China has not formally adopted such rating standards. In the absence of such standards, developers are competing with each other based on their own self-reported indicators of their buildings' "greenness". We create an index using Google search to rank housing complexes in Beijing with respect to their "marketing greenness" and document that these "green" units sell for a price premium at the presale stage but they subsequently resell or rent for a price discount. An introduction of a standardized official certification program would help "green" demanders to acquire units that they desire and would accelerate the advance of China's nascent green real estate market. Highlights ► China has not formally adopted rating standards for "green" buildings. ► We create a Google index to rank "marketing greenness" of housing complexes in Beijing. ► Developers charge a price premium for self-reported buildings' "greenness" during presale. ► These "green" premiums disappear in the subsequent resells and the rental market. ► A standardized certification program would advance China's nascent green real estate market.

Abstract It has been widely observed that China is under-urbanized. The central government has tried to use various policies to promote urbanization. In this paper, we evaluate one of these policies - count-to-city upgrading. Under China's hierarchical governance structure, a city status can only be determined and awarded by the central government. In the 1980s and 1990s, China adopted a formula-based county-to-city upgrading policy. Based on a large panel dataset covering all counties in China, we find that the formula was not strictly enforced in the practice. Moreover, jurisdictions that were upgraded to cities prior to 1998 do not perform better than their counterparts that remained county status in terms of both economic growth and providing public services. Largely because of these problems, this policy was called off in 1997. Given the strong need for urbanization, more indigenous institutional innovations are needed to find a viable way of creating cities, which would also provide compatible incentives to local governments. Highlights ► We examine a failed county-to-city upgrading policy in China. ► The newly awarded cities had a lackluster performance because the upgrading process was irreversible. ► After the policy was called off, China has adopted more indigenous institutional innovations in creating cities.

Thématique n° 2 [ScienceDirect, via Biblio-SHS] Auteur : Hui Wang, Lanlan Wang, Fubing Su, Ran Tao Paru dans : Habitat International, Volume 36, Issue 2, April 2012, Pages 201-209 Abstract Rural residential land represents one of the most important land use types in China. However, the literature so far has paid insufficient attention to the patterns and efficiencies of this type of land use. To fill in this gap, this paper uses a national survey to analyze the institutional setups for rural residential land use, to assess the effectiveness of existing regulations, and to evaluate the efficiencies in rural residential land use. Farmers' subjective receptiveness toward rural residential property regulation reform is also investigated. We find that rural residential properties are inefficiently utilized under the existing land use regulations, that those who are younger and who had previous migration experiences are more likely to support the free trading of rural residential properties while the village cadres are more likely to oppose it. A coordinated policy reform package that includes free trading of rural residential properties and Household Registration System to facilitate permanent migration out of the countryside is proposed to address the existing efficiencies in China's rural residential land use. Highlights ► Rural residential land is an important land use type in China. ► Under existing regulations rural residential land is inefficiently used. ► A coordinated land-Hukou reform package is needed to address the inefficiency.

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

The simulation of land use change is important in environmental impact assessment and land use planning. We assessed the land use scenarios of China in the next 100 years based on the SMLC (surface modelling of land cover change) model and Dyna-CLUE (dynamic conversion of land use and its effects) model. Three SRES scenarios were evaluated: Global Economy (A1FI): lean government, strong globalization; Continental Markets (A2a): lean government, regional culture and economic development; Regional communities (B2a): much government intervention, regional cultural and economic development. Ten land cover types were simulated, which are cultivated land, woodland, grassland, built-up land, water area, wetland, nival area, desert, bare rock and desertification land. The SMLC model was used to calculate changes in area for each land use types in the future at country level while the spatially explicit land use model Dyna-CLUE was used to simulate land use pattern at 2 km2 resolution based on the country level areas demands for each land cover type. The results show that the cultivated land would decrease in all of the three scenarios, while in the A2a scenario, the cultivated land would decrease with the lowest rate because of the high population growth, high level of market protection and low agricultural efficiency; in the B2a scenario, it would decrease with the highest rate caused by the decreased population numbers and increased crop productivity. The nival area would decrease with the highest rate in the A1FI

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.

Luciano Cessari, Elena Gigliarelli In: Progress in Cultural Heritage Preservation Lecture Notes in Computer Science Volume 7616, 2012, pp 369-377 Abstract Climate change have impacts on many sectors: land use, housing, transportation, public health, water supply and sanitation, solid waste, food security, and energy. This article presents the results of the project SECHURBA, financed by European funds, whose purpose was to examine the potential of environmental protection and sustainability in historic cities, documenting barriers and prospects of various historical communities with diversity in Europe. Critical objectives which were achieved, such as 'Historic Community Climate Change Strategies', assessment tools, route maps to intervene in areas such culturally sensitive, are under implementation in historic urban areas in Popular Republic of China. Through the application to some typical towns and villages in the Chinese province of Zeijang the outcomes of SECHURBA will developed to outline a set of actions and tools that will call 'Historic Cities Regeneration by Climate Change Strategies'.

Thématique n° 2 [ScienceDirect, via Biblio-SHS] Auteur : Jing Wu, Joseph Gyourko, Yongheng Deng Paru dans : Regional Science and Urban Economics, Volume 42, Issue 3, May 2012, Pages 531-543, Special Section on Asian Real Estate Market Abstract High and rising prices in Chinese housing markets have attracted global attention. Price-to-rent ratios in Beijing and seven other large markets across the country have increased by 30% to 70% since the beginning of 2007. Current price-to-rent ratios imply very low user costs of no more than 2%-3% of house value. Very high expected capital gains appear necessary to justify such low user costs of owning. Our calculations suggest that even modest declines in expected appreciation would lead to large price declines of over 40% in markets such as Beijing, absent offsetting rent increases or other countervailing factors. Price-to-income ratios also are at their highest levels ever in Beijing and select other markets, but urban income growth has outpaced price appreciation in major markets off the coast. Much of the increase in prices is occurring in land values. Using data from the local land auction market in Beijing, we are able to produce a constant quality land price index for that city. Real, constant quality land values have increased by nearly 800% since the first quarter of 2003, with half that rise occurring over the past two years. State-owned enterprises controlled by the central government have played an important role in this increase, as our analysis shows they paid 27% more than other bidders for an otherwise equivalent land parcel.
