在全球化和市场转型的背景下，中国的城市更新出现了一系列新的特征，并对城市的社会空间产生了前所未有的深刻影响。本研究基于政治经济分析的研究框架，主要运用城市政体理论对当前中国的城市更新及其空间特征进行分析研究，探讨不同利益主体如何在城市更新的决策和运作中扮演不同角色，并结成特定"政体"对城市更新模式的地域差异及其社会空间后果产生影响。本研究主要选取出现在珠三角及长三角地区大城市的多类城市更新模式作为研究对象，从都市区、城市次区域、城市邻里社区多个空间尺度对更新决策的形成、各利益主体的角色及其权力结构、更新项目的运作、社会空间后果进行系统的分析。本研究还将对城市更新在不同地域和尺度上产生的社会空间后果进行多元统计分析、社会网络分析、和空间可视化的分析。本研究旨在为深入理解中国当代城市更新的政治经济内涵和空间地域特征，以及由此引发的社会空间重构提供有意义的理论探讨和实践经验。

Against the backdrop of globalization and market transtion,urban redevelopment in China possesses a number of new features, and imposes profound influence upon urban social spaces. This project is based on a research framework of political economy analysis, which mainly applies the urban regime theory to examine urban redevelopment and its spatial characteristics in Chinese cities.Specifically, this research is to investigate the role of various interest groups in the decision-making process of urban redevelopment, how they form different development "regime" , and how the regime affect the redevelopment mode and its spatial differentiation and socio -sptial consequences.This research takes multiple forms of urban redevelopment emerging in the Pearl River Delta and the Yangtze River Delta as study cases, aiming to carry out a multiscalar (at the scale of metropolitan area, urban district,and urban community) and systematic analysis on the decision-making processes, different roles of the interest groups and their power structure, the operationalization of redevelopment projects, and its socio-spatial consequences. This research will also conduct multi-varieables statistical analysis and social networks analysis, as well as spatial visualization to make sense of the socio-sptial consequences of urban redevelopment in different places and scales.This project will combine theoretical exploration and emperical studies to provide an in-depth understanding of the political economy and spatiality of urban redevelopment, and the resulting socio-spatial reconfigulation in contemporary Chinese cities.
