中国绿色经济效率的影响因素及空间效应

Influencing Factors and Spatial Effects of China’s Green Economy Efficiency

基于2011—2021年省级面板数据,通过超效率SBM(基于松弛值测算)模型测算绿色经济效率,运用空间杜宾模型对绿色经济效率的影响因素进行分析。结果表明:绿色经济效率具有空间溢出效应;经济发展水平和政府干预对其具有抑制作用,技术水平和教育投入则有促进作用;从区域层面看,西部地区的经济发展水平对绿色经济效率的抑制作用和技术水平对其促进作用均高于东中部地区,而政府干预对其抑制作用弱于东中部地区,东部地区的教育投入其促进作用强于中西部地区。

Based on provincial panel data from 2011 to 2021,the super efficiency SBM(slacks-based measure)model was used to measure the green economic efficiency,and the spatial Durbin model was used to analyze the influencing factors of green economic efficiency.The results show that green economic efficiency has a spatial spillover effect.The level of economic development and government intervention have a restraining effect on it,while the level of technology and education investment have a promoting effect.From a regional perspective,the level of economic development in the western region has a higher inhibitory effect on green economic efficiency and a higher promoting effect of technological level on it than in the eastern and central regions.However,government intervention has a weaker inhibitory effect on it than in the eastern and central regions,and the promoting effect of education investment in the eastern region is stronger than that in the central and western regions.
