数字鸿沟视角下数字经济发展对共同富裕的影响

The Impact of Digital Economy Development on Common Wealth in the Perspective of Digital Divide

党的二十大报告中提出要加快发展数字经济,扎实推进共同富裕。以2011—2019年中国168个城市为样本,探讨了在数字鸿沟存在的情形下,数字经济发展和共同富裕之间的关系。研究发现,由于数字鸿沟的存在,数字经济发展对共同富裕的影响不是线性而是“U形”的。影响机制分析表明,数字经济可以通过产业结构高级化、劳动力转移影响共同富裕水平,数字鸿沟在这种关系中起到了显著的调节作用。数字鸿沟的存在一方面会通过阻碍产业结构升级、引起劳动力转移“回流”降低数字经济对共同富裕的积极影响,另一方面会使这种影响呈现出显著的区域异质性。研究结果对如何缩小数字鸿沟,促进数字经济发展赋能共同富裕提供了一定的政策启示。

The 20th Party Congress report proposes to accelerate the development of digital economy and solidly promote common prosperity.This paper explores the relationship between digital economy development and common wealth in the presence of the digital divide in a sample of 168 Chinese cities from 2011 to 2019.The study finds that the impact of digital economy development on common wealth is not linear but"U-shaped"due to the existence of the digital divide.The analysis of the impact mechanism shows that the digital economy can affect the level of common wealth through the advanced industrial structure and labor transfer,and the digital divide plays a significant moderating role in this relationship.The existence of the digital divide can reduce the positive impact of the digital economy on the common wealth by hindering the upgrading of industrial structure and causing the"return"of labor transfer on the one hand,and make the impact show significant regional heterogeneity on the other.The findings of this paper provide some policy implications on how to narrow the digital divide and promote the development of the digital economy for the common prosperity.
