摘要
通过分析京津冀地区碳排放效率的空间分布特征,对区域环境治理和经济可持续发展提供科学依据和战略支持。使用最近邻法构建了空间权重矩阵,通过莫兰指数检验发现该地区的碳排放效率存在显著的空间相关性,即相邻地区的碳排放效率具有较高的相似性。使用空间杜宾模型对碳排放效率进行了回归分析,发现产业结构、经济发展水平、技术进步等因素对碳排放效率有正向促进作用,并且周边碳排放效率高的地区对本地区的碳排放效率也具有正向驱动作用。对多元回归模型中各变量的直接效应、间接效应和总效应进行解释,总体来看,人口密度、节能减排目标完成情况、研发投入占GDP比重和第三产业占比等因素对被解释变量的影响比其他因素更为显著。
By analyzing the spatial distribution characteristics of carbon emission efficiency in the Beijing-Tianjin-Hebei region,this paper provided scientific basis and strategic support for regional environmental governance and sustainable economic development.Firstly,in this paper,the nearest neighbor method was used to construct the spatial weight matrix.The Moran index test showed that there was a significant spatial correlation between the carbon emission efficiency in the region.That is,the carbon emission efficiency of adjacent areas was highly similarly.And then,the spatial Durbin model was used toconduct regression analysis on carbon emission efficiency.It was found that factors such as industrial structure,economic development level and technological progress had a positive effect on the carbon emission efficiency,and the surrounding areas with high carbon emission efficiency also had a positive driving effect on the carbon emission efficiency of the region.Finally,the direct effect,indirect effect and total effect of each variable in the multiple regression model were explained.In general,the impact of population density,the completion of energy-saving and emission reduction targets,the proportion of R&D investment in GDP and the proportion of the tertiary industry on the explained variables was more significant than other factors.
