保障性住房布局的社会公平绩效评价体系——基于南京市多源数据的实证研究

THE SOCIAL EQUITY PERFORMANCE EVALUATION SYSTEM OF AFFORDABLE HOUSING LAYOUT:AN EMPIRICAL STUDY BASED ON MULTI-SOURCE DATA IN NANJING

新型城镇化对关怀弱势群体提出了更高的要求。针对保障性住房布局公平性衡量体系的缺失问题,本文在现有规划体系中构建社会公平绩效评价体系,具体包括多元数据平台构建、基本公共服务设施可达性计算、社会公平和空间公平衡量三个阶段,并通过南京市的实证研究,阐述各个阶段的技术方法。其中,多源数据收集是通过手机信令数据、兴趣点数据、房价数据、开放地图出行成本数据等构建数据平台;基本公共设施可达性计算则通过对于不同出行时间、出行工具、出行目的的可达性进行计算;在公平性衡量阶段进行模块分析评价,明确基于社会公正理论下的社会公平、空间公平的评价结果。

New urbanization puts forward higher requirements for the care for disadvantaged groups.In view of the lack of an equity evaluation system for the affordable housing layout,it is advisable to develop a social equity performance evaluation system in the existing planning system.Specifically,it includes three stages:construction of a multi-source data platform,calculation of accessibility of basic public service facilities,and measurement of social equity and spatial equity.Through an empirical study in Nanjing,the technical methods of each stage are explained.Among them,multi-source data collection is to build a data platform based on the mobile phone signaling data,point of interest data,housing price data,open map travel cost data,etc.Basic public facility accessibility is calculated based on destination accessibility through different travel modes at different travel times.The module analysis and evaluation are performed in the equity evaluation stage,and the evaluation results of social equity and spatial equity based on the justice theory are clarified.
