数字普惠金融对共同富裕的影响及其区域异质性——基于富裕、平等和共享协同的视角

Impact of digital financial inclusion on common prosperity and its regional heterogeneity:a perspective of prosperity,equality,and shared collaboration

从系统观念出发阐释共同富裕内涵并构建与测度了包含富裕度、平等度与共享度子系统的共同富裕指数,深入分析了数字普惠金融影响共同富裕的理论机制,基于2011—2020年的省级面板数据利用GMM方法进行了实证检验。研究发现,数字普惠金融均显著提升了富裕度、平等度、共享度,有利于促进全体人民共同富裕,不同稳健性结果均支持这一结论。数字普惠金融显著地促进了共同富裕子系统的综合协调与良好耦合,体现了从系统视角协同促进共同富裕的必要性。异质性分析表明,数字普惠金融对共同富裕的促进效应在东部更大,存在随时间递减的时变特征,覆盖广度、使用深度与数字化水平的促进效应依次由大变小。

From the systemic perspective,this study elucidates the connotation of common prosperity,constructs and measures a Common Prosperity Index including the subsystem of wealth,equality and sharing,and analyzes the theoretical mechanism of digital inclusive finance influencing common prosperity.Based on the provincial panel data from 2011 to 2020,an empirical test was conducted employing the Generalized Method of Moments(GMM)methodology.The findings reveal that digital financial inclusion significantly promotes affluence,equality and sharing,and is conducive to promoting the common prosperity of all people.Robustness checks consistently support this conclusion.Digital inclusive finance has significantly enhanced the comprehensive coordination and effective coupling of the subsystems of common prosperity,highlighting the necessity of synergistically promoting common prosperity from a systemic perspective.Heterogeneity analysis shows that the promotion effect of digital inclusive finance on common prosperity is more substantial in the eastern region,with a time-varying feature of diminishing impact over time.The promotion effect successively decrease with the breadth of coverage,depth of usage,and level of digitization.
