社会拓扑视角下城市密度演化动态与治理机制研究——以北京市为例

在我国城市化进程中，超大城市空间治理日益成为完善国家治理体系和治理能力所面临的一个重大课题，包括城市密度在内的城市空间动态成为城市治理的对象和立足点。立足人文地理和城市研究领域关于社会拓扑理论的探讨，项目聚焦城市密度的社会空间内涵，采用参与式观察、深度访谈、问卷调查、批判话语分析、扩展案例分析等复合研究方法，探究城市密度的动态演化过程及其与城市治理体系的紧密关联。项目以城市密度的多层次演变机制为抓手，重点关注城市的权力逻辑和密度的日常形态，推进城市密度形态的社会拓扑结构分析和密度表征的政治经济分析，探讨特定城市密度转化为“生活空间”的具体作用机制。在理论层面构建城市物质性与政治经济逻辑之间的分析桥梁，不仅能够有效推进整合性的城市密度拓扑理论框架的生成，而且还将为更加包容的城市治理实践构建新的地理学理论基础，推动形成更加多元、动态和包容的城市治理政策体系。

The ongoing transformation of urban spaces has been inducing critical challenges for China’s urban governance system. These challenges are even more significant in mega-cities, where the governance of spatial dynamics, including changing urban densities, has been foregrounded as a key aspect of the local state’s policy schemes. This project engages with recent reflections on the social topology to reconceptualise urban density as a remaking process of the manifold socio-spaces. It adopts mixed methods, including participant observation, in-depth interviews, surveys, critical discourse analyses and extended case methods, so as to investigate the process of density making and remaking and to shed new lights on our understanding of the relations between urban density and urban governance. This project draws on the empirical observations of the multiple mechanisms through which urban densities are being made and reshaped. And the focus is put on the power logics and lived forms that are underlying different urban densities. The analytical goal is to put forward a social-topological analysis of these density forms while at the same time develop a political-economic critique of these density representations. Equally critical here is a further exploration of the process through which certain urban densities have been made into the “lived spaces” for the urban majority. With such progress, the project will eventually manage to bring together the two lines of inquires between urban materiality and urban political economy; and this will in turn contribute to the production of a more integrated theoretical framework on “the topology of urban density.” On top of this, this project may also pave the way for a new and reflexive geographical-theoretical foundation for more inclusive urban policy schemes.
