基于因子分析和聚类分析的公众雾霾敏感度差异研究——以西安市为例

Research on Public Haze Sensitivity Difference Based on Factor Analysis and Cluster Analysis:A Case of Xi’an City

为研究公众的雾霾敏感度,以西安市13个区为案例地,运用因子分析法对公众的敏感度进行降维,引入潜在冲突指数(PCI)分析公众雾霾敏感度各维度的内部差异,并对公众进行分类。结果表明:(1)公众的雾霾敏感度可分为5个维度,分别是防护行为、降霾行为、雾霾关注度、生活影响感知和健康影响感知;(2)公众在防护行为、降霾行为、生活影响感知和健康影响感知方面意见一致,且敏感度较高;在雾霾关注度方面,公众之间的分歧较大,雾霾关注度小的公众敏感度较低;(3)基于以上5个维度,将公众分为防护敏感群体、关注度敏感群体、健康敏感群体和环保敏感群体。

In order to study the sensitivity of the public to haze,taking 13 districts of Xi’an as cases,this paper used factor analysis to reduce the sensitivity of public,introduced potential conflict index to analyze the internal differences of haze sensitivity of public,and classified the public.The results showed that:(1)The haze sensitivity of public could be divided into five dimensions:protective behavior,haze reduction behavior,haze attention,life impact perception and health impact perception;(2)Public had the same views on protective behavior,haze reduction behavior,life impact perception and health impact perception,and they are highly sensitive;but there were great differences among public in terms of haze attention and public with less haze concerns were less sensitive;(3)Based on the above five dimensions,public were divided into protective sensitive groups,attention sensitive groups,health sensitive groups and environmental sensitive groups.
