数字经济对城乡收入差距的影响研究

Study on the Impact of the Digital Economy on Urban-Rural Income Gap

摘要: 本文基于2011~2021年31个省级面板数据，采用熵权法测算数字经济水平综合指数，运用固定效应、中介效应和门槛效应模型探究数字经济对城乡收入差距的影响。研究表明：数字经济可以显著缩小城乡收入差距；数字经济对城乡收入差距的影响存在受教育程度的双重门槛效应，在低门槛值下数字经济对城乡收入差距的呈现缩减作用；城镇化水平作为中介变量会在一定程度上影响数字经济对城乡收入的差距；异质性分析发现，南方地区数字经济对城乡收入差距的影响比北方地区显著。

Abstract: Based on 31 provincial panel data from 2011 to 2021, this paper uses entropy weight method to measure the comprehensive index of digital economy level, and uses fixed effect, intermediary effect and threshold effect models to explore the impact of digital economy on urban-rural income gap. The results show that the digital economy can significantly narrow the urban-rural income gap; The impact of digital economy on the urban-rural income gap has a double threshold effect of education level. Under the low threshold value, the reduction effect of digital economy on the urban-rural income gap is gradually increasing. The level of urbanization as an intermediary variable will affect the gap between urban and rural income of digital economy to some extent. Heterogeneity analysis shows that digital economy has a more significant impact on urban-rural income gap in southern China than in northern China.
