Institutional Change and urban redevelopment Process:A Case Study of Changshoujie,Shanghai

引用

China City Planning Review 2014年第1期23卷 16-25页

作者： Ze LI Pei-ju Perry YANG Tianjie ZHANG Department of urban Planning School of ArchitectureTianjin University School of City and Regional Planning Georgia Institute of Technology

Through investigating the institutional change and urban development in Shanghai since 1978,this research identifi es that the gradual economic reforms have generated dynamic forces for urban development. 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.
