摘　　要：中等收入群体扩容有助于缩小收入差距,降低社会不平等,加快实现共同富裕。文章从收入阶层流动的视角探究数字经济发展在共同富裕目标中的作用,从理论上分析数字经济发展对低收入群体收入阶层向上流动的影响,并利用中国家庭追踪调查数据(CFPS)进行实证检验。研究发现:第一,截至2018年,我国仍有68.67%的家庭处于低收入阶层,“金字塔型”收入分配结构明显,低收入阶层向上流动缓慢;第二,数字经济发展促进了低收入群体收入阶层向上流动,有助于实现中等收入群体扩容,该结论在多种稳健性检验和内生性处理后仍成立;第三,机制检验发现,家庭创业、理财参与和就业水平提升是数字经济发展促进低收入群体收入阶层向上流动的重要渠道;第四,异质性分析发现,数字经济发展对低收入群体收入阶层向上流动的促进效应在西部和经济发展水平较低的地区更显著,并且与城镇和低人力资本家庭相比,这种促进效应在农村家庭和高人力资本家庭中更强。文章的研究发现为数字经济发展促进共同富裕提供了新的论据。Achieving common prosperity is the essential requirement of socialism and an important symbol of building a modern and powerful socialist country with Chinese characteristics.The key to solidly promoting common prosperity lies in promoting low-income group to increase their income,expanding the scale of middle-income group,eliminating the polarization of income distribution,gradually narrowing the income distribution gap,and realizing the transformation of income distribution structure from"pyramidal"to"olive".However,the current income distribution in China is not optimistic,with the Gini coefficient of 0.468 in 2020,which is significantly higher than the internation-al alert line of 0.4,and more than 60%of the residents do not reach the middle-income standard proposed by the Na-tional Bureau of Statistics.Narrowing the income gap and expanding the size of the middle-income group are impor-tant goals for China during the 14th Five-Year Plan.In the context of the disappearance of demographic dividend,de-mand contraction,supply shock and weakened expectations,how to achieve the expansion of the middle-income group is an urgent issue for us to consider and solve.The digital economy as a new economic model provides a strong impetus for sustainable and healthy economic and social development,and while the country promotes the expansion of middle-income scale,it also emphasizes the need to actively promote the development of digital economy.During the 14th Five-Year Plan period,the digital economy should shift to a new stage of deepening application,standardizing development and sharing for the benefit of all,and continue to promote profound changes in the modes of production,life and governance.Can the inclusive sharing of digital economy alleviate the problem of insufficient income growth of low-income group,promote their up-ward mobility and expand the middle-income group?To address these questions,the article theoretically analyzes the characteristics of each income class and the impact of digital economy developm
