数字经济对城乡居民收入差距的影响探究

Exploring the Impact of Digital Economy on the Income Gap between Urban and Rural Residents

数字经济作为一种新的经济形态,正逐渐推动着居民收入水平的提升和社会经济的发展。通过收集2011—2020年中国30个省市(不包括西藏和港澳台地区)的数据,从数字经济基础设施、互联网发展、数字普惠金融3个维度进行数字经济水平的测算,利用固定效应模型探究数字经济对城乡居民收入差距的影响。研究结果表明:数字经济对城乡居民收入差距的增大具有显著的抑制作用,数字经济通过城镇化水平和基础设施水平的提升缩小城乡居民收入差距。数字经济发展对于城乡居民收入差距具有区域异质性,采用替换核心解释变量和缩尾处理的方法进行稳健性检验后结论仍成立。因此,要全面推进数字经济高质量发展,进一步缩小城乡居民收入差距。

As a new form of economy,the digital economy is gradually promoting the improvement of residents'income levels and the development of social economy.By collecting data from 30 provinces and cities in China(excluding Tibet,Hong Kong,Macao and Taiwan)from 2011 to 2020,this paper calculates the level of the digital economy from three dimensions of digital economy infrastructure,Internet development,and digital financial inclusion,and explores the impact of the digital economy on the income gap between urban and rural residents using the fixed effect model.The results show that the digital economy has a significant inhibitory effect on the increase of income gap between urban and rural residents.The digital economy reduces the income gap between urban and rural residents through the improvement of urbanization level and infrastructure level.The development of digital economy has regional heterogeneity in the income gap between urban and rural residents.After conducting robustness tests using the method of replacing core explanatory variables and conducting tail reduction,the conclusion still holds.Therefore,it is necessary to comprehensively promote the high-quality development of the digital economy and further narrow the income gap between urban and rural residents.
