数字经济发展对代际收入流动的影响研究

The Study on the Impact of Digital Economy Development Level on Intergenerational Income Mobility

摘要: 发展数字经济助推共同富裕，是当前广受关注的焦点话题。作为共同富裕的重要度量，社会代际流动能否在数字经济时代下得以改善具有深远的研究价值。本文探讨了数字经济在促进中国代际收入流动性的影响及其内在机制。利用2013至2019年的中国家庭金融调查数据库，本文从理论和实证角度出发，探讨了数字经济对代际收入流动的影响及其背后机制。研究结果表明，数字经济对于提高代际收入流动性具有显著正向影响，并且通过工具变量法、更改测度方法、精确子代年龄范围等检验依然稳健。进一步研究发现，这一作用通过弱化代际劣势传递、强化能力有用论、扩大子代社会资本和优化经济结构等机制实现。本文为数字变革下如何提升社会流动性以及实现共同富裕提供新的政策建议。

Abstract: The development of the digital economy as a driver for common prosperity is a focal point of current attention. As an important measure of common prosperity, whether social intergenerational mobility can be improved in the digital economy era holds profound research value. This paper explores the impact of the digital economy on intergenerational income mobility in China and its underlying mechanisms. Utilizing the China Household Finance Survey from 2013 to 2019, this paper examines the impact of the digital economy on intergenerational income mobility and its mechanisms from both theoretical and empirical perspectives. The results show that the digital economy has a significant positive impact on intergenerational income mobility, which remains robust through instrumental variable methods, changes in measurement methods, and precise sub-setting of offspring age ranges. Further research finds that this effect is realized through mechanisms such as weakening intergenerational disadvantage transmission, strengthening the human capital hypothesis, expanding offspring social capital, and optimizing economic structure. This paper provides new policy suggestions for how to enhance social mobility and achieve common prosperity under digital transformation.
