数字经济发展缩小城乡收入差距了吗？——来自中国城市的经验证据

摘要/Abstract

摘要： 缩小城乡收入差距是推动共同富裕的主攻方向之一，与此同时，全球进入数字时代，数字经济对城乡收入差距造成了显著影响。本文探究了数字经济影响城乡收入差距的理论逻辑和具体机制，采用中国285个地级及以上城市数据，通过构建数字经济指标体系，利用固定效应模型、广义矩估计、面板门槛模型等方法进行了实证分析。结果表明，数字经济与城乡收入差距存在显著的U型关系，稳健性检验和内生性检验较好地支撑了这一结论。机制分析表明，数字经济可通过推动城镇化等方式缩小城乡收入差距。门槛回归分析显示，数字经济对城乡收入差距的作用效果受到人均GDP、科学技术支出占GDP比重这两个变量的调节影响。基于理论分析和实证结果，为缩小城乡收入差距提出了具有针对性的政策建议。

Abstract: Narrowing the income gap between urban and rural areas is one of the most important ways to promote common prosperity. At the same time, the world has entered the digital era, and the digital economy has had a significant impact on the income gap between urban and rural areas. This paper explores the theoretical logic and specific mechanism of the impact of digital economy on the urban-rural income gap. Using the data of 290 cities in China, this paper makes an empirical analysis by constructing the digital economy index system and using the fixed-effect model, generalized moment estimation, panel threshold model and other methods. The results show that there is a significant U-shaped relationship between digital economy and urban-rural income gap, which is well supported by robustness test and endogeneity test. Mechanism analysis shows that digital economy can narrow the urban-rural income gap by promoting the level of urbanization. Threshold regression analysis shows that the effect of digital economy development on urban-rural income gap is regulated by per capita GDP and the proportion of science and technology expenditure in GDP. Based on the theoretical analysis and empirical results, this paper puts forward some targeted policy suggestions to narrow the urban-rural income gap.
