摘　　要：城镇居民收入差距是导致我国整体收入差距持续处于高位的重要原因,作为数字经济的重要组成部分,产业数字化对城镇居民收入差距的影响值得关注。本文利用企业数字化转型指数测算城市层面产业数字化水平,使用CHIP2013和CHIP2018调查数据,实证检验产业数字化对城镇居民收入差距的影响。研究发现:第一,城镇居民收入差距对我国整体收入差距的贡献不断提高,是导致我国整体收入差距持续位于高位的重要原因;第二,产业数字化转型显著扩大了城镇居民收入差距,该结论在引入Bartik工具变量、替换解释变量、删除直辖市样本后依然稳健;第三,从居民收入结构层面来看,产业数字化主要通过提高居民财产性收入占比、提高高收入人群财产性收入、扩大财产性收入差距影响城镇居民收入差距;第四,产业数字化扩大城镇居民收入差距的效应主要集中于低人口密度、低经济密度、低产业数字化水平、数字基础设施完备的城市。因此,在加快推进产业数字化的同时,拓宽低收入群体财产性收入渠道、提高低收入人群财产性收入水平成为未来发展数字经济、缩小收入差距的重点。The income inequality among urban residents is a significant factor contributing to the sustained high level of overall income inequality in China.As an important part of the digital economy,the impact of industrial digitalization on the income inequality among urban residents deserves attention.This paper uses the digital transformation index of enterprises to measure the level of industrial digitalization at the city level and utilizes the CHIP 2013 and CHIP 2018 survey data to empirically examine the impact of industrial digitalization on income ine-quality among urban residents,and finds that first,the contribution of the urban income inequality to the overall income inequality in China is continuously increasing,which is an important reason for the sustained high level of overall income inequality in China.Second,industrial digitalization significantly widens the income inequality among urban residents.This conclusion remains robust after introducing the Bartik instrument variable,replacing the explanatory variable,and excluding the samples of municipalities directly under the central government.Third,from the perspective of the structure of urban residents'income,industrial digitalization mainly affects the urban income inequality by increasing the proportion of property income in residents'total income,raising the property income of high-income groups,and widening the gap in property income.Fourth,the effect of industrial digitalization on widening the urban income gap is mainly concentrated in cities with low population density,low economic density,low levels of industrial digitalization,and well-developed digital infrastructure.Therefore,while accelerating the digitalization of industries,broadening the channels for property income of low-income groups and increasing their level of property income has become a key focus for the future development of the digital economy and narrowing the in-come gap.
