基于主成分分析的网格事件区域弱势性分析

Vulnerability Analysis of Grid Event Region Based onPrincipal Component Analysis

针对社区治理粗放、社区网格事件缺乏有效分析手段等问题,以A区为研究对象,采用主成分分析,在街道层面进行社区网格事件区域弱势性分析,并在此基础上采用聚类分析,对各维度弱势性指数进行统计分析。结果显示,社区网格事件区域弱势性存在明显的差异性,对社区网格事件数据挖掘分析进而服务于社区网格化治理具有一定的指导意义。

In view of the problems of extensive community governance and the lack of effective analysis methods for community grid events,this paper takes district A as the research object,adopts principal component analysis to analyze the regional vulnerability of community grid events at the street level,and on this basis,adopts cluster analysis to carry out statistical analysis on the vulnerability index of each dimension.The results show that there are obvious differences in the regional vulnerability of community grid events,which has certain guiding significance for the community grid event data mining and analysis to serve the community grid governance.
