保障政策下的城市住房来源构成时空演变分析——以浙江省为例

Spatio-temporal evolution analysis of urban housing source composition under security policy——A case study of Zhejiang province

基于2000-2015年间普查和抽样调查的住房来源数据,构建市场型、保障型、自有型、租赁型住房比重指标,动态分析16年间浙江省城市家庭住房来源构成的变化。通过系统聚类分析自然间断点分级法,将4个住房比重指标借助ArcGIS做空间格局及整体演变分析,构建时空轨迹,直观反映住房来源空间分布格局的演变,以期全面把握省域住房来源体系的演变,促进住房市场的有序发展。

Based on the housing source data from 2000 to 2015 census and sample survey,the proportion indexes of market-type,security-type,self-owned and rental-type housing were constructed,dynamically analyzing the change of urban household housing source composition in Zhejiang province throughout the 16 years. By applying the method of hierarchical cluster analysis and natural breakpoint classification,the spatial pattern and overall evolution of the four housing proportion indexes were analyzed by virtue of ArcGIS,and the spatio-temporal trajectory was constructed to directly reflect the evolution of the spatial distribution pattern of housing sources,for the sake of fully grasping the evolution of the provincial housing source system and promoting the orderly development of the housing market.
