数字经济发展对城乡融合影响效应的实证检验

An Empirical Test of Impact of Digital Economy Development on Urban-rural Integration

文章基于中国31省份2011-2020年的面板数据进行实证研究,发现数字经济发展对城乡融合具有显著的促进作用,且存在从东部到中部、再到西部依次递增的区域异质性;同时,这种促进作用随数字经济发展水平和地区经济发展水平的变化而呈现非线性特征。当前,中国部分省份的经济发展水平已经超越了面板门槛模型中的门槛值,对于这些省份而言,通过发展数字经济促进城乡融合的条件已经具备。机制检验结果显示,数字经济发展可通过市场机制、政府行为和社会服务三条中介渠道驱动城乡融合。

Based on the panel data of 31 provinces in China from 2011 to 2020,this paper conducts an empirical study and obtains the following findings:The development of digital economy has a significant promoting effect on urban-rural integration,and there is an increasing regional heterogeneity from the east to the central and western regions.At the same time,this promoting effect presents nonlinear characteristics with the change of the development level of digital economy and regional economic devel-opment level.Currently,the economic development level of some provinces in China has exceeded the threshold value in the panel threshold model.For these provinces,conditions are in place to promote urban and rural integration through the development of the digital economy.The mechanism test results show that the development of digital economy can drive urban-rural integration through three intermediary channels:market mechanism,government behavior and social service.
