公租房公共设施空间可达性研究——以深圳为例

Accessibility of Public Rental Housing to Public Facilities:the Case of Shenzhen

以深圳市为例,研究公租房周边公共设施的空间可达性及影响因素。首先,采用核密度分析2012—2017年深圳公租房的空间布局特征,发现总体上呈现“南山前海–深圳北周边”双核集聚的特征;然后,基于ArcGIS和层次分析法构建可达性评价指标体系,将深圳各区公租房公共设施的综合可达性分为3个梯队。最后,指出宏观调控政策、建设方式和设施数量均会影响公租房公共设施的可达性,使用混合OLS和固定效应模型,发现在3种主要建设方式中,城市更新配建方式对提高公租房的公共设施可达性影响显著,集中新建和地铁上盖建设方式影响微弱。

Using Shenzhen as a case,this paper examines the spatial accessibility of public rental housing to public facilities and its impact factors.First,the spatial distribution of public rental houses in Shenzhen from 2012 to 2017 is analyzed through nuclear density analysis method,and the spatial pattern shows a dual-core clustering called“Qianhai-Shenzhenbei”.Second,ArcGIS and analytic hierarchy process are used to develop an index system of spatial accessibility,and the spatial accessibility of various districts are divided into three levels.Finally,mixed OLS and fixed effect model are used to study the development mode as an impact factor of the spatial accessibility.The result shows that macro policies,development methods and public facilities can affect the spatial accessibility.Among three main types of development modes,urban renewal development has the most significant impact,while the new centralized-built development and the upper cover development have much less impacts.
