Accurate Evaluation of Supply-Demand Matching Quality of 15-Minute Community Life Circle in Shanghai
摘要
Abstract
Evaluating the quality of supply and demand matching of community living circle services based on the distribution of specific demand groups can accurately guide the planning improvement.This paper proposes a set of methods for identifying the demand groups and evaluating the service level of facilities.Mobile phone data and the seventh population census data are used to identify the spatial distribution of demand groups,and POI data is used to measure the distribution of corresponding facilities.The accurate evaluation of the supply-demand matching is conducted by combining accessibility analysis.Based on the five types of facilities specified in Shanghai's 15-Minute Community Life Circle Action Guide,the Lorentz curve and Gini coefficient are first used for overall evaluation,and then the service level of sub-types of facilities in the central city and suburban areas are analyzed at the kilometer grid scale to identify potential problems.The study shows that:service equality varies across different types of facilities,and some facilities have obvious spatial problems;the construction of a community life circle needs to go beyond the administrative division of street/town,and in some cases,it also needs to consider the optimization of road connectivity;it is not appropriate to set absolute accessibility standards for the suburban living circle,which should be determined by the usage of different facilities.关键词
