数字经济、创业活跃度与共同富裕——来自智慧城市建设的证据

Digital Economy, Entrepreneurial Activity and Common Prosperity—Evidence from Smart City Construction

智慧城市建设是推动中国数字经济发展的核心载体,是数字经济发展水平的直观体现。文章以智慧城市建设为背景,基于2002—2020年中国城市面板数据,采取多期DID方法,实证分析了数字经济发展对共同富裕的影响效应及作用机理。结果发现,数字经济发展有利于激发城市创业活跃度,从而显著提升共同富裕水平,在进行安慰剂检验和控制其他相似政策的冲击等稳健性检验后,这一结论仍然成立。进一步研究表明,在行政级别高、地理区位具有优势的城市中,数字经济发展对共同富裕的影响效应更为明显。

The construction of smart cities is the core carrier and a direct manifestation of the development level of China’s digital economy.Taking smart city construction as the background,based on the panel data of 287 cities in China from 2002 to 2020,this essay made an statistical analysis on the impact and mechanism of digital economy development on common prosperity using Time-varying DID.The results show that the development of digital economy is conducive to the urban entrepreneurs and significantly promoting the development of common prosperity.This conclusion is still valid after the placebo test and the robustness test of controlling the impact of other similar policies.Further research shows that the impact of digital economy development on common prosperity is more obvious in cities with higher administrative levels and more advantageous geographical locations.
