Does digital inclusive finance affect the urban green economic efficiency? New evidence from the spatial econometric analysis of 284 cities in China

Abstract

Digital inclusive finance has an essential impact on improving the urban green economy efficiency by demonstrating environmental friendliness in agglomerating factors and promoting the flow of factors. Based on the panel data of 284 cities in China from 2011 to 2020, this paper uses the super-efficiency SBM model with undesirable outputs to measure the urban green economy efficiency. Then, the fixed effect model and spatial econometric model of panel data are used to empirically test the impact of digital inclusive finance on urban green economic efficiency and its spatial spillover effect, and the heterogeneity analysis is carried out. This paper draws the following conclusions. (1) The average value of urban green economic efficiency of 284 Chinese cities from 2011 to 2020 is 0.5916, showing a "high in the east and low in the west." In terms of time, it showed a rising trend year by year. (2) Digital financial inclusion and urban green economy efficiency have a high spatial correlation, both showing "high-high" and "low-low" agglomeration characteristics. (3) Digital inclusive finance significantly impacts urban green economic efficiency, especially in the eastern region. (4) The impact of digital inclusive finance on urban green economic efficiency has a spatial spillover effect. In the eastern and central regions, digital inclusive finance will inhibit the improvement of urban green economic efficiency in adjacent cities. In contrast, it will promote urban green economy efficiency in the western regions in adjacent cities. (5) The coverage and depth of digital inclusive finance significantly affect the urban green economy efficiency, while the level of digitization has yet to show a significant effect. This paper puts forward some suggestions and references for promoting the coordinated development of digital inclusive finance in various regions and improving urban green economic efficiency.
