数字金融与收入差距——基于多维视角的综合分析

Digital Finance and Income Gap:A Comprehensive Analysis Based on Multi-dimensional Perspective

数字金融与收入差距是当前中国乃至全世界面临的两大重要课题。本文尝试采用多维数据从国内与国外、宏观与微观、直接与间接等多个视角综合考察数字金融对收入差距的影响。本文首先从宏观层面的国内、国外两大视角出发检验数字金融与收入差距之间的关系及其影响机制,之后以中国上市公司数据为样本,对数字金融存在的拉大高收入群体间收入差距的作用进行了检验,并有以下发现。第一,数字金融缩小了国家内部的收入差距,但数字金融与收入差距间存在着潜在“U”型关系,创新是上述潜在“U”型关系的重要解释,这与以往研究显示的简单线性关系不同。第二,数字金融拉大了国家之间的收入差距,并且这种扩大趋势在高收入国家中更加明显。第三,数字金融拉大了高收入群体间的收入差距,这一结论同时得到宏观和微观两个层面的实证支持。整体来看,本文不仅为数字金融与收入差距关系提供了新的经验证据,而且为如何通过数字金融发展缩小收入差距、实现共同富裕提供了理论依据。

The relationship between digital finance and income inequality is a crucial topic that deserves a deeper examination.This study aims to explore the impact of digital finance on income inequality through a multi-dimensional approach,by analyzing both domestic and international perspectives,macro and micro levels,and direct and indirect effects.The study starts by verifying the relationship between digital finance and income inequality at the macro level,considering both domestic and international perspectives.Results suggest that digital finance reduces income inequality within a country,however,there is a potential U-shaped relationship,where innovation plays a crucial role.The study also finds that digital finance widens income inequality between countries,with a more pronounced trend among high-income countries.The study then shifts to the micro level,using data from Chinese listed companies to test the impact of digital finance on income inequality.Results indicate that digital finance exacerbates income inequality among high-income groups.This view is supported by evidence from both macro and micro perspectives.This study provides new insights into the relationship between digital finance and income inequality and highlights the importance of innovation in reducing income gaps through digital finance development.The findings of this study offer a theoretical reference for policymakers seeking to achieve common prosperity through the development of digital finance.
