摘　　要：文章构建了包含城乡和技能异质性的代理人模型,以分析数字经济对居民收入分配差距的影响与作用机制,使用2010—2019年省级面板数据和CGSS2010—2018年的面板数据,运用工具变量法验证了数字经济对居民收入分配差距的影响,并进行了稳健性、异质性与影响机制检验。研究结果表明:第一,数字经济扩大了居民收入分配差距。使用替换指标的方法进行稳健性检验,结果表明研究结论是稳健的。第二,数字经济对居民收入分配差距的影响存在区域异质性。数字经济对居民收入分配差距的影响在东部地区和中部地区是显著的,在西部地区和东北地区不显著。第三,技能溢价是数字经济影响居民收入分配差距的渠道,数字经济发展会扩大城乡收入差距。This paper constructs an agent model that includes urban-rural and skill heterogeneity to analyze the influence and mechanism of the digital economy on residents’income distribution gap,then uses the provincial panel data from 2010 to 2019 and CGSS panel data from 2010 to 2018 and adopts the instrumental variable method to verify the impact of the digital economy on residents’income distribution gap.Finally,the paper conducts robustness,heterogeneity and impact mechanism tests.The research results are shown as the following:First,the digital economy has widened the income distribution gap among residents.The results of robustness test using the method of replacing indicators indicate that the research conclusions are robust.Secondly,there is regional heterogeneity in the impact of digital economy on residents’income distribution gap.The impact of the digital economy on the income distribution gap of residents is significant in the eastern and central regions,while not significant in the western and northeastern regions.Thirdly,skill premium is the channel by which the digital economy affects the income distribution gap of residents,and the development of digital economy will widen the income gap between urban and rural areas.
