Abstract:Based on the unexpected super-efficiency SBM model, the green total factor productivity (GTFP) of my country from 2005 to 2019 was measured under the constraints of resources and environment, and the impact of digital financial inclusion on GTFP was explored with the help of the spatial econometric model, and finally the mediation effect model was constructed. Join technological innovation and financial development to study the transmission mechanism of digital inclusive finance to GTFP. The results show that my country's GTFP is at a relatively low level as a whole. During the sample observation period, the overall difference of my country's GTFP shows a cyclical fluctuation trend of rising first and then falling. The regional differences are significant, showing the characteristics of high in the east and low in the west. The spatial correlation test shows that my country's GTFP and digital financial inclusion have obvious spatial correlation, and the Moran index scatterplot shows the characteristics of high-high aggregation and low-low aggregation; the spatial econometric model shows that digital financial inclusion has a significant impact on GTFP. The effect of is a significant positive promotion effect, and the indirect effect is greater than the direct effect. The results of the mediation effect model show that digital financial inclusion can indirectly promote the growth of GTFP through technological innovation and financial development. Based on this, the government should vigorously develop digital inclusive finance, promote the process of modernization, give full play to the role of innovation, and then promote the development of green total factor productivity and achieve high-quality economic development.
