摘　　要：公众环境意识水平的高低将直接影响区域环境状况。选取2012—2018年长三角城市群27个地级市年度百度搜索指数和2018年社会经济环境数据,基于地理加权回归模型分析社会、经济、环境因素对公众环境意识指数影响的空间异质性。研究结果表明:(1)2012—2018年间,长三角城市群公众环境意识指数呈“M”形变化趋势;(2)长三角城市群公众环境意识水平存在明显空间差异,重点城市公众环境意识指数水平显著高于其他城市;(3)多数影响因素对公众环境意识指数呈现正负两种效应,且具有明显的空间异质性,经济层次中外商直接投资因素呈现正向影响,社会层次中人口密度因素呈现负向影响,常住人口性别比因素呈现正向影响。The level of public environmental awareness directly affects regional environmental conditions and green sustainable development.The development of big data provides another perspective for the measurement of environmental awareness.The study selected the annual Baidu Search Index and 2018 socio-economic-environmental statistics of 27 prefecture-level cities in the Yangtze River Delta urban agglomerations from 2012 to 2018,and analyzed the spatial heterogeneity of the influence of socio-economic-environmental factors on the public environmental awareness index based on GWR model.The results show:(1) the public environmental awareness index of the Yangtze River Delta urban agglomeration shows an "M"-shaped trend from 2012 to 2018;(2) the level of public environmental awareness index of key cities is significantly higher than that of other cities,and there are obvious spatial differences;(3) most of the influencing factors show either positive or negative effects on the public environmental awareness index.For example,the amount of foreign direct investment and the gender ratio of the resident population has a positive effect,while population density has a negative effect on public environmental awareness.Based on the above analysis,we put forward some policy suggestions,for example,city governments should pay as much as possible attention on environmental issues in their economic development,and so on.
