城市有机更新——基于理性选择理论的反思

Urban Organic Renewal:Reconsideration based on Rational Choice Theory

城市更新是我国城市发展每一个阶段都需要关注的空间规划问题。为提升国土空间治理能力和效率,城市更新成为重要议题。作为自上而下的国土空间治理实践,早期城市更新以理性选择理论思维规划,在寻找城市更新“最优解”的过程中忽视了城市更新除去经济、政治功能外,“以人为本”的深层本质。于是在部分城市进行城市有机更新的实践中体现了对于作为理性选择理论中信息、理性、偏好和最大化的思考。文章将以成都市二环内的部分城市有机更新项目为例,分析城市有机更新基于理性选择理论的反思,并论述城市有机更新中这种反思对于“以人为本”城市建设的作用。

Urban renewal is a spatial planning issue that needs attention at every stage of urban development in China. In order to improve the capacity and efficiency of land space governance, urban renewal has become an important issue. As a top-down practice of land spatial governance,early urban renewal was planned with theoretical selection theory thinking, and the deep essence of urban renewal in addition to economic and political functions was ignored in the process of finding the optimal solution of urban renewal. Therefore, in the practice of urban organic renewal in some cities, the thinking on information, rationality, preference and maximization as a rational choice theory is reflected. This paper will take some urban organic renewal projects in the Second Ring of Chengdu as an example, analyze the reflection of urban organic renewal based on rational choice theory, and discuss the role of this reconsideration on the construction of people-oriented cities in urban organic renewal.
