数字普惠金融对经济增长质量的影响——基于西部地区85个地级市的实证研究

The Impact of Digital Inclusive Finance on the Quality of Economic Growth:An Empirical Study based on 85 Prefecture-level Cities in Western ChinaMA Qing

选取2011—2022年间我国西部地区85个地级市的面板数据,采用固定效应模型分析数字普惠金融及其三个维度即覆盖广度、使用深度和数字化程度对西部地区经济增长质量的影响。研究表明,数字普惠金融及其三个维度对西部地区经济增长质量的提升均具有正向影响,其中,覆盖广度的影响最强,其次是使用深度、数字化程度;采用经济发展水平为门槛变量构建面板门槛模型,发现这种影响存在非线性的门槛效应,经济发展水平较高,其对经济增长质量的影响也较强;进一步研究还发现,科技创新和居民消费水平在推动数字普惠金融促进西部地区经济增长质量方面发挥一定的中介作用,但这些作用相对较小。

This paper selects panel data from 85 prefecture-level cities in Western China from 2011 to 2022,and uses a fixed-effects model to discuss the impact of digital inclusive finance and its three dimensions:Coverage breadth,usage depth,and degree of digitalization on the quality of economic growth in the region.The study shows that digital inclusive finance and its three dimensions all have a positive effect on enhancing the quality of economic growth in Western China,with coverage breadth having the strongest impact,followed by usage depth and degree of digitalization.Using the level of economic development as a threshold variable to construct a panel threshold model,the study finds a nonlinear threshold effect,with higher levels of economic development corresponding to stronger impacts on the quality of economic growth.Further research also reveals that technological innovation and the level of consumer spending play a certain mediating role in promoting the quality of economic growth through digital inclusive finance in Western China,although these effects are relatively small.
