数字经济发展是否有助于提升城市包容性绿色增长水平——来自“国家智慧城市”试点的证据

Does the development of the digital economy contribute to enhancing the level of inclusive green growth in cities-Evidence from“the nation smart city”pilot

包容性绿色增长作为一种绿色共享式增长,是促进实现全体人民共同富裕的重要途径。基于2008~2020年地级市面板数据,以“国家智慧城市”试点政策作为城市数字经济发展的外生冲击,探讨数字经济发展对城市包容性绿色增长水平的影响。结果表明,数字经济发展显著促进了城市包容性绿色增长水平的提升,在一系列稳健性检验后该结论依然成立。从传导机制上看,数字经济发展通过资源配置效应和技术创新效应显著促进了城市包容性绿色增长水平的提升。从空间效应上看,数字经济发展能显著促进邻近城市包容性绿色增长水平的提升。从异质效应上看,数字经济发展对包括经济发展、财政分权以及城市规模等不同特征城市包容性绿色增长水平的促进作用存在差异。

As a kind of green shared growth,inclusive green growth is an important way to promote common prosperity for all people.Based on the panel data of prefecture level cities from 2008 to 2020,and taking the“National Smart City”pilot policy as the exogenous impact of urban digital economy development,this paper discusses the impact of digital economy development on urban inclusive green growth.The results show that the development of digital economy has significantly promoted the improvement of urban inclusive green growth,and this conclusion is still valid after a series of robustness tests.From the perspective of transmission mechanism,the development of digital economy has significantly promoted the level of inclusive green growth in cities through resource allocation effects and technological innovation effects.From the perspective of spatial effects,the development of digital economy can significantly promote the improvement of inclusive green growth levels in neighboring cities.From the perspective of heterogeneity effects,there are differences in the promotion effect of digital economy development on the level of inclusive green growth in cities with different characteristics,including economic development,fiscal decentralization,and urban size.
