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

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

As an example,this paper examines Changshoujie in detail to uncover its physical changes and to explore how the actors' roles and interests interplay as well as how the transitional institutions of property rights and urban planning have impacted the shaping of urban space. 117 projects constructed since 1978 are classifi ed into six development modes according to the characteristics of land users and developers. Although there is a time lag,the path depending on institutional change has a direct impact on urban development and the consequent spatial structure.展开更多

The current traffic impact analysis （TIA） is lack of a comprehensive component for non-motorized transportation under redevelopment. For a better guidance of land redevelopment and non-motorized transportation planning, it is necessary to evaluate the negative impact of redevelopment on non-motorized traffic in the TIA. In this paper, an evaluation framework for the impact analysis is built up. We organized the pro- cedures and components of impact evaluation, and proposed the corresponding qualitative and quantitative evaluation indicators for non-motorized traffic under redevelopment. Level of service （LOS） and its criterion are employed for external impact evaluation, and level of safety, convenience, independence, and comfort which are four aspects of quality of service （QOS） are proposed to analyze the internal impact. The framework is applied to a redevelopment study in Shanghai, China. The case study results indicate that the rede- velopment from a residential area to a mixed commercial area has a significant impact on non-motorized traffic. The potential negative impact from both external and internal traffic can be minimized by reasonable improvements in the internal land use design.展开更多

Due to the development of urban economy and the transition of the traditional industrial structure, many historic cities and towns both at home and abroad have witnessed a large scale "demolition" and abandonment of industrial buildings in urban renewal during last 30 years. Consequently, it has been leading to the discontinuity of urban cultural and historic context. The paper discusses and expounds the clas...展开更多
