摘要
文章运用2012—2019年我国长三角26个城市的面板数据作为研究样本,利用双向固定效应模型分析了长三角城市群数字经济发展对区域碳排放强度的影响,并引入中介变量产业结构,然后在此基础上进行异质性分析。研究发现:第一,长三角城市群数字经济的发展显著降低了区域碳排放强度;第二,引入中介变量产业结构,发现数字经济能通过优化产业结构来降低碳排放强度;第三,异质性分析结果显示,长三角数字经济发展对区域碳排放强度的影响具有显著的异质性。
In this paper,the panel data of 26 cities in China's Yangtze River Delta from 2012 to 2019 are used as research samples,and the two-way fixed effect model is used to analyze the impact of digital economy development in Yangtze River Delta urban agglomeration on regional carbon emission intensity,and the industrial structure of intermediary variables is introduced,and then the heterogeneity is analyzed on this basis.The findings are as follows:Firstly,the development of digital economy in the Yangtze River Delta urban agglomeration significantly reduces the intensity of regional carbon emissions;secondly,by introducing intermediary variable industrial structure,it is found that digital economy can reduce carbon emission intensity by optimizing industrial structure.Thirdly,the results of heterogeneity analysis show that the influence of the development of digital economy in the Yangtze River Delta on regional carbon emission intensity is significantly heterogeneous.
