人才争夺何以影响城市高新技术产业的发展？——基于273个城市的准自然实验

How does competition for talents affect the development of urban high-tech industry: A quasi-natural experiment based on 273 cities

摘要:

基于2010-2019年273个地级及以上城市的面板数据,将人才争夺战中城市实施的人才引进政策作为准自然实验,运用多期双重差分法考察人才引进政策的政策效果,研究结果表明:(1)城市人才引进政策对城市高新技术产业发展的提升作用显著,且这种政策效应自政策颁布的第二年起愈发显著。(2)在不同地区和不同城市规模间,城市人才引进政策对于高新技术产业发展的政策效应存在差异。(3)科技创新水平和科技研发投入水平是人才引进政策促进城市高新技术产业发展的中介因素。稳健性检验的结果支持上述结论。

Abstract:

Based on the panel data of 273 cities in China from 2010 to 2019, the study selects the “quasi-natural experiment” of the talent introduction policy in urban talent war, and employs difference-in-difference (DID) approach to conduct the policy evaluation. Empirical results show that: (1) Urban talent introduction policy promotes the development of urban high-tech industry significantly, and this effect has been strengthened since the second year of the policy implementation. (2) In different regions and different city sizes, urban talent introduction policy may exert unlike impact on high-tech industry. (3) The level of scientific and technological innovation and spending play an intermediary role in the relationship between the implementation of talent introduction policy and the development of urban high-tech industry. Robustness tests support conclusions above.
