数字普惠金融对县域产业结构升级的门槛效应研究——以贵阳市为例

Study on the Threshold Effect of Digital Inclusive Finance on the Upgrading of County Industrial Structure:Taking Guiyang City as an Example

文章基于2016-2021年贵州省贵阳市10个区县的面板数据,使用门槛模型,考察数字普惠金融与县域产业结构升级的关系。研究结论发现:数字普惠金融覆盖广度、县域经济增长水平分别在数字普惠金融与县域产业结构升级之间发挥单门槛效应和双门槛效应;当数字普惠金融覆盖广度超过门槛值1.0328时,数字普惠金融对县域产业结构升级有显著的正向影响效应;当县域经济增长水平在门槛值14.4824和15.6927间时,数字普惠金融对县域产业结构升级作用显著增强。

Based on the panel data of 10 districts and counties in Guiyang,Guizhou Province from 2016 to 2021,this paper uses a threshold model to investigate the relationship between digital inclusive finance and the upgrading of county industrial structure.The results show that the coverage of digital inclusive finance and the level of county economic growth play a single threshold effect and a double threshold effect between digital inclusive finance and the upgrading of county industrial structure,respectively.When the coverage breadth of digital inclusive finance exceeds the threshold value of 1.0328,digital inclusive finance has a significant positive effect on the upgrading of county industrial structure.When the level of county economic growth is between 14.4824 and 15.6927,the effect of digital inclusive finance on the upgrading of county industrial structure is significantly enhanced.
