摘　　要：在推进城乡融合发展和数字经济时代全面到来的背景下,深入探讨数字经济发展与城乡居民收入差距的关系,对更好地解决城乡不平衡发展具有重要意义。基于2011—2021年中国226个城市的数据,运用熵权法求得各市的数字经济发展水平,运用双向固定效应模型实证检验数字经济发展对城乡居民收入差距的影响。结果发现:①数字经济对城乡居民收入差距的影响呈现出先缩小后扩大的“U”型趋势,目前中国大部分城市位于“U”型曲线的右侧,结论经过一系列检验后依然成立。②分区域来看,数字经济发展对中国东、中、西和东北区域的城乡居民收入差距的影响均呈现先减后增的态势,且通过计算发现东部地区“拐点”值最大,即在数字经济发展的更高水平上才经历了这一转变。③进一步分析发现,金融活跃程度和人力资本水平可以削弱数字经济发展带来的城乡居民收入差距扩大效应。据此提出,在推进数字经济发展的同时,应多措并举弥合城乡“数字鸿沟”,依据不同发展阶段和实际情况制定地区差异化发展战略,提高金融支持力度以及增加教育资源投入,从而改善数字经济冲击引致的城乡居民收入差距扩大现象。Under the background of promoting the integrated development of urban and rural areas and the full arrival of the digital economy era,it is of great significance to explore in depth the relationship between digital economy development and the income gap between urban and rural residents to better solve the unbalanced development of urban and rural areas.Based on the data of 226 cities in China from 2011 to 2021,the entropy weight method is used to find out the level of digital economy development of each city,and the two-way fixed effects model is used to empirically test the impact of digital economy development on the income gap between urban and rural residents.It is found that:①the impact of the digital economy on the income gap between urban and rural residents shows a U-shaped trend of narrowing and then expanding,and most of the cities in China are located on the right side of the U-shaped curve,and the conclusion is still valid after a series of tests.②From a regional perspective,the impact of digital economy development on the income gap between urban and rural residents in the eastern,central,western and northeastern regions of China shows a trend of decreasing first and then increasing,and it is found that the eastern region has the largest"inflection point"value,i.e.,it has experienced this transformation only at a higher level of digital economy development.③Further analysis reveals that the degree of financial activity and the level of human capital can weaken the effect of urban-rural income expansion brought about by the development of the digital economy.Accordingly,it is proposed that,while promoting the development of the digital economy,measures should be taken to bridge the"digital divide"between urban and rural areas,regionally differentiated development strategies should be formulated in accordance with the different stages of development and the actual situation,and financial support and investment in educational resources should be increased,so as to ameliorate the widening of the u
