摘要
基于2012—2019年中国285个城市的面板数据,利用EBM-GML指数和空间杜宾模型实证考察数字金融发展对绿色经济效率及绿色发展差距的经济效应、异质特征和传导渠道。研究发现:数字金融与绿色经济效率之间呈U形关系;数字金融发展会拉大群际绿色发展差距,加剧绿色发展不平等;数字金融的三个子维度和不同城市等级对城市绿色经济效率的影响存在异质性;绿色技术创新和产业结构升级是数字金融影响绿色经济效率的主要路径,而绿色技术创新和地区创业水平的差异是绿色发展差距扩大的主要原因。
Drawing on the panel data of 285 cities in China from 2012 to 2019,this paper uses EBM-GML index and spatial Dubin model to empirically examine the economic effects,heterogeneous characteristics and transmission channels of digital financial development on green economy efficiency and green development gap.The results show that there is a positive U-shaped relationship between digital finance and green economy efficiency.Digital finance can widen intergroup green development gap and aggravate the inequality of green development.The effects of three sub-dimensions of digital finance and different city levels on the efficiency of urban green economy are heterogeneous.Green technology innovation and industrial structure upgrading are the main ways for digital finance to affect green economy efficiency,while the gap between green technology innovation and regional entrepreneurship level is the main source of widening green development gap.
