Abstract:  Based on the panel data of Chinas cities from 2011 to 2018, this paper analyzes the intermediary effect of digital economy development on urban-rural income gap by influencing regional market potential. The conclusions are as follows: (1) The development of digital economy helps to narrow the urban-rural income gap, and the transmission role of market potential in the process of narrowing the urban-rural income gap in the development of digital economy has been supported. (2) From a national perspective, the market potential constitutes the intermediary variable for the development of digital economy to narrow the urban-rural income gap. Group regression shows that the transmission effect of market potential is supported in western regions and regions with high industrial structure upgrading index. (3) The development of digital economy affects the urban-rural income gap through the chain intermediary effect and multiple intermediary effect that affect the income of urban and rural residents.

近年來,缩小居民收入差距,推动实现共同富裕,成为政策制定和学术研究的重要方向(罗楚亮等,2021)。城乡收入差距过大是我国整体居民收入不平等问题的重要构成(Teng et al.,2010;Lagakos,2020),而数字经济健康有序发展是缩小城乡收入差距,逐步破解发展不平衡不充分难题,满足人民美好生活需求的崭新驱动力(张勋等,2021)。本文从市场潜力的视角出发,研究数字经济发展影响城乡收入差距的内在机理,探索数字经济发展能否缩小城乡收入差距,为构建新发展格局,切实转变发展方式,推动更有效率、更加公平、更可持续的发展提供理论和经验支撑。
