It relieves environmental pressure and resolves the glaring contradiction between urban land idleness and urban sprawl. It addresses issues of urban land use and farmland protection in China. This paper compares brownfield with greenfield, and defines brownfield and its redevelopment. It elaborates general and special government policies for this sustainable land use strategy in the context of China. General policies contain two aspects: clarifying brownfield redevelopment's priority in Chinese urban planning and land use and setting a general quantitative redevelopment target. The extent of the government's special policies, which aim at coordinating three factors in the redevelopment process, namely govern- ments, developers and users, are divided into five areas: statistics and categorization, assessment and remediation, fi- nancial supports and tax incentives, environmental and legal liability, and publicity and guidance. The paper concludes the major functions of different levels of Chinese government in the redevelopment process, i.e. making general strategy, formulating legislation, spectifying regulations and technical standards, estimating and categorizing brownfield sites, drawing up brownfield planning, providing information and financial support, guiding developers, publicizing the strategy to the public, and checking reuse results.展开更多

The modes and trajectories of urban redevelopment have thus become areas of major concern for both policymakers and scholars. Taking the multi-actor participation nature of redevelopment, this paper stemming from the game-theoretical approach demonstrates in empirical terms on two major fronts. First, the redevelopment of industrial land without the transfer of land use right is shown to be deadlocked by the incapacitation of the original land-user and unlocked with the participation of the new developer. Second, the preference of the original land-user to maximize its interests by operating by itself rather than continue to cooperate with the new developer is observed in the post-redevelopment stage. Therein, the entrepreneurial local government acts only as a “mediator” between the two market entities and tends not to directly intervene in their cooperation. Thus that, it is the reasonable distribution of potential benefits or the pricing of different rights in the land property right bundle rather than their definition that matters more for land redevelopment. Because the delineation of land property rights has never been a problem in a mature land market, particularly for stock industrial land.展开更多

Housing marketization provides an opportunity for households to choose their residences. However, not all households benefit equally from residential relocation. Residential relocation in urban China has relatively strong association with the household’s position within the spectrum from state redistribution to market reward than with life cycles and consequent adjustment of housing demand, which are the primary reasons for residential mobility in a mature market. In this research we focused on social aspects, mainly relating to the impact of urban redevelopment in inner city of Ningbo and the resultant potential housing problem. This research is based on a questionnaire survey that was conducted in three neighborhoods redeveloped at different time periods in the past fifteen years. The findings suggest that new strategy of redevelopment of the integrated envi-ronment of the old city while still improving the living condition for its residents can be heard due to the efforts of many people at various positions. Yet, many things need to be done to change people’s ideas: information and education through newspapers, academic discussions through academic journals, conferences, and reports to decision makers.展开更多

Studies on gentrification in Chinese cities began to take off in the 2000 s. However, they all mainly focused on the newly emerging global cities and there has been a lack of investigation on provincial cities. Furthermore, discussions on gentrifiers′ profiles and their motivations for housing choice are absent from literature on Chinese gentrification. Therefore, this paper aims to assess the relevance of the broad definition of gentrification in provincial Chinese cities through empirical research on urban redevelopment projects in Chengdu, and to examine the characteristics of gentrifiers(as new incoming residents) in it. The results show the rationality of gentrification processes as urban redevelopment in Chengdu, and reveal original outcomes on the corresponding gentrifiers′ profiles and the motivations behind their housing choice, which are different from the general features of gentrifiers in standard Western gentrification research.展开更多

China's experience in establishing urban land markets is characterized by trial and error and the gradual evolution of transitional institutions. Based on archive data and interviews in a neighborhood(Jinhuajie) of Guangzhou,this research reveals that China's land redevelopment in the past two decades has followed an approach of partial and gradual reform,which was structured by the gradual evolution of transitional institutions to speed up local land redevelopment within the existing property rights system. Transitional institutions,including highly compensated residents' land use rights,in-kind land lease payment,flexible control on development rights of developers and short-term actual ownership of work units,are generated by the local government sequentially to dispel existing land use rights of different land users and make further development be able to follow market mechanisms.展开更多

The boundary red line of urban growth, the red line of the number of basic farms and the ecology red line makes the local to conserve land. Land stock for village and town construction is a huge amount of potential resources. Redevelopment of land for village and town construction provides ensured land security for the smooth progress of urbanization. Combining village and town construction land use characteristics and making in-depth analysis of the difficulties in the redevelopment of village and town construction and its inner mechanism, policies and suggestions were proposed for the redevelopment of village and town construction land in terms of land property, land price, market allocation, planning, surveillance and so on, so as to provide valuable reference for the smooth redevelopment of village and town construction land, and the system design of villages and towns.展开更多

The program employs the modularization method to perform functions including one-key initialization of the process planning environment,creation and deletion of blanking steps,automatic identification of belt coordinates,recognition of the number of blanking steps in each domain,and the output and import of process data. The difficult problem of recognizing CAD block references with the same name in the automatic acquisition of belt coordinates is solved using the selection sets method,which greatly improves the efficiency of the process design,while also guaranteeing rapid development of the flexible data mold in stepping-mode laser blanking.展开更多

Manufacturing, especially, automobile industry created and continued the thriving economy in Detroit, MI in the early to mid-1900s. When outsourcing impacted the industry, people began to leave the city. That turned into a demographic catastrophe in Detroit. Economy had continuously fallen and many of the properties were foreclosed. After the housing market crash in 2008, a big economic crisis effected all country. After such a strong economic crisis, Detroit has been desperately in need of economic revival which has begun to turn around very slowly in last 10 years. In this paper, Detroit has been investigated through the experienced constructional problems. Sustainable solutions for Detroit are discussed in a broader aspect. The main purpose of the research is to understand the current problems in construction in Detroit after a decade of the economic crisis and bring sustainable solutions for urban redevelopment and rehabilitation for Detroit. Paper also details the problems in Detroit area, reasons behind the complications, components/parameters, constraints/limitations, solutions, people involved and expected results.展开更多
