数字普惠金融对代际收入流动性的影响研究

Research on the Impact of Digital Inclusive Finance on Intergenerational Income

本文利用中国2012-2020年宏微观匹配数据,考察数字普惠金融对代际收入流动性的影响效应及作用机制。研究发现:数字普惠金融的发展有助于提高我国代际间的收入流动性,特别是能够促进低收入家庭子代代际收入向上流动,且这种促进作用在不同地区、不同子代性别以及不同收入阶层的家庭间表现出显著的异质性。进一步分析检验结果表明,数字普惠金融通过缓解家庭流动性约束促进代际收入流动,但同时增加了家庭债务风险发生的可能性,进而又抑制了代际收入流动。

This paper uses macro-micro matching data of China during 2012-2020 to examine the impact of digital in-clusive finance on intergenerational income mobility and its mechanism.It is found that the development of digital inclu-sive finance can help improve intergenerational income mobility in China,especially in promoting upward intergenerational income mobility for low-income families'offspring.This promoting effect shows significant heterogeneity among families in different regions,with different genders of offspring,and in different income classes.Further analysis and testing results in-dicate that digital inclusive finance promotes intergenerational income mobility by alleviating household liquidity con-straints,but at the same time increases the possibility of household debt risks,which in turn suppresses intergenerational income mobility.
