摘　　要：数字经济已成为促进中国经济增长的重要引擎,是推动实现共同富裕的重要力量。文章探讨了数字经济影响共同富裕的理论机制,并使用2013—2019年中国266个城市面板数据,采用固定效应模型、调节效应模型、有限混合模型等方法实证检验数字经济对共同富裕总体水平及其分项维度的影响与作用。研究发现:数字经济整体上可有效推进共同富裕,具体表现为可显著提高富裕水平,但对共同水平的影响并不显著;政府财政支出的增加可以显著改善数字经济对共同水平的推动作用,金融发展水平的提高则能有效改善数字经济对富裕水平的推动作用;利用有限混合模型识别出中国城市层面数字经济发展对共同富裕存在三条路径,各路径的赋能效果具有差异,经济发展水平和城镇化水平的提高将加速路径转化,进而增强城市数字经济对共同富裕的赋能效果。基于研究结论,提出应大力支持数字技术研发,多措并举跨越数字鸿沟,并实施差异化的数字经济发展战略,推动中国共同富裕水平的提高取得实质性进展。The digital economy has become a new pillar to stabilize Chinese economic growth and an important engine to promote common prosperity under the current high-quality development.The theoretical mechanisms by which the digital economy affects common wealth are explored,and empirically tests the impact and influence of the digital economy on the overall level of common prosperity and its sub-dimensions using panel data of 266 Chinese cities from 2013 to 2019,employing fixed-effects models,moderated-effects models,and finite-mixed models.During the sample period,the digital economy has a significant positive impact on the level of common wealth,which is conducive to raising the income level of residents and significantly improving the level of affluence.However,the digital economy does not show a significant impact on the common dimension,and the digital divide may exist.The development of digital economy in general can strongly improve the level of common wealth,especially performs well in“making bigger cake”,and in the future it should focus on doing better“sharing the cake”.Through the construction of the moderating effect model,it is found that government financial expenditure significantly weakens the growth of the digital economy on the affluent dimension,which has a negative moderating effect,but significantly enhances the growth of the digital economy on the common dimension.The level of financial development promotes the growth of the digital economy on the level of the affluent,while in the common dimension.The level of financial development has delayed the increase of the common level,which shows a significant negative moderating effect,obvious negative moderating effect.The influence role of digital economy on common affluence is heterogeneous,using the finite mixture model to identify the existence of three influence paths of digital economy on common affluence in Chinese cities,which are categorized into low-efficiency,medium-efficiency and high-efficiency groups according to the empowerment eff
