【摘要】 首次将腾讯研究院发布的地级市层面“互联网+”数字经济指数与2018年中国流动人口动态监测调查数据(CMDS)相匹配，实证分析了数字经济对于劳动力跨地市流动的影响。研究发现，一个城市数字经济发展水平提升能够显著吸引劳动力的跨地市流入，该结论在经过内生性处理和一系列稳健性检验后依然成立。机制分析结果表明，数字经济主要是通过提供创业机会和提高劳动力预期收入来促进劳动力流动的。此外，数字经济对于劳动力跨地市流动影响具有显著地区异质性，表现为在东部地区，数字经济发展抑制了劳动力的跨地市流入，而在中部地区则相反，在其他地区该影响不明显；与城镇劳动力相比，农村劳动力的边际流动倾向更高，说明数字经济发展具有益贫性；且劳动力更偏好于流入数字经济发展较好的城镇部门。研究结论为数字经济背景下地方政府吸引人才和促进劳动力要素合理配置提供了有益参考。更多还原

【Abstract】 This paper matches the “Internet +” digital economy index at the prefecture city level released by Tencent Research Institute with the data of the 2018 China Floating Population Dynamic Monitoring Survey(CMDS), and empirically analyzes the impact of the digital economy on the flow of labor across cities. The study found that the improvement of the digital economy development of a city can significantly attract the inflow of labor across cities, and this conclusion is still valid after endogenous treatment and a series of robustness tests. The results of the mechanism analysis show that digital economy mainly promotes labor mobility by providing entrepreneurial opportunities and increasing the expected income of the labor force. In addition, the impact of digital economy on the movement of labor across cities has significant regional heterogeneity, as manifested in the fact that in the eastern region, the development of digital economy significantly inhibits the inflow of labor across cities, while in the central region, the result is the opposite, and the impact is not significant in other regions. Compared with urban labor, the marginal mobility of rural labor is higher, indicating that the development of digital economy has pro-poorness. Besides, the labor force prefers to flow into urban areas. This paper provides a useful reference for local governments to attract talents and promote the rational allocation of labor factors under the background of digital economy.更多还原
