数字普惠金融对提升绿色全要素生产率影响及其空间效应

The Impact of Digital Financial Inclusion on Improving Green Total Factor Productivity and Its Spatial Effect

提升绿色全要素生产率是实现我国经济高质量发展的关键。本文采用非期望产出—超效率SBM模型结合GML指数的方法测算我国30个省份的绿色全要素生产率(GTFP),同时构建空间杜宾模型定量分析数字普惠金融对地区GTFP的空间溢出效应,并通过中介效应模型检验两者之间的传导机制。研究发现,数字普惠金融发展不仅会提升本地区GTFP,还有助于提升邻近地区的GTFP,并且这种空间溢出效应在东部地区更为明显。机制分析方面,数字普惠金融通过碳排放强度和技术创新影响GTFP。在碳减排和创新环境的支持下,可以强化数字普惠金融对GTFP的提升力度。

Improving green total factor productivity is the key to achieve high-quality economic development in China.This study employs a non-expected output-super-efficiency SBM model combined with a GML index to assess the green total factor productivity(GTFP)across 30 provinces in China.Additionally,a spatial Durbin model has been developed to quantitatively analyze how digital financial inclusion impacts regional GTFP through spatial spillover effects,while testing their interplay using an intermediate effect model.The findings indicate that the development of digital financial inclusion will not only increase GTFP in the region,but also help to increase GTFP in neighboring regions,and this spatial spillover effect is more obvious in the eastern region.In terms of mechanism analysis,digital financial inclusion influences GTFP through carbon emission intensity and technological innovation.With the support of carbon reduction and innovation environment,digital financial inclusion can strengthen the improvement of green total factor productivity.
