创新驱动政策如何提升城市科技人才集聚水平?OA

Against the backdrop of intensifying global technological competition,talent serves as a critical driver of economic growth.How policy can promote talent agglomeration has become a key societal concern.This paper takes the National Independent Innovation Demonstration Zones(NIIDZ)policy as a quasi-natural experiment.Drawing on the national innovation system and push-pull theory,and utilizing panel data from 278 prefecture-level and above cities in China from 2003 to 2022,it constructs a multi-period difference-in-differences model to assess the impact of innovation-driven policies,exemplified by the NIIDZ policy,on scientific and technological(S&T)talent agglomeration in cities,and the underlying mechanisms. The findings reveal that the NIIDZ policy can increase S&T talent agglomeration in cities by leveraging government strategic guidance and promoting industrial-structure transformation.The policy exerts a stronger effect on talent agglomeration in municipalities and provincial capitals.Across city size categories,the policy exhibits the most pronounced impact in large cities,a moderate impact in medium and small cities,and the weakest impact in megacities.It also generates positive effects in the eastern and western regions,yet shows no significant effect in the central region.Furthermore,the policy demonstrates a more substantial promoting effect on S&T talent agglomeration in cities within urban agglomerations. The marginal contributions lie in three aspects.First,it integrates the NIIDZ policy and S&T talent agglomeration into a unified analytical framework to examine the talent agglomeration effects of innovation-driven policies,thereby broadening the scope of existing research.Second,it investigates the mechanisms underlying the impact of the NIIDZ policy on S&T talent agglomeration,thereby enriching the understanding of determinants of S&T talent agglomeration and extending the applicability of established theoretical frameworks.Third,it analyzes the heterogeneous effects of the NIIDZ policy on S&T talent agglomeration across multiple dimensions,offering theoretical support for policy implementation and the enhancement of cities'S&T talent agglomeration levels. This paper suggests that the government should value the top-level design and institutional arrangements for S&T talent agglomeration within innovation-driven policies and fully leverage these effects.It is also essential to optimize the pathways through which national innovation-driven policies enhance S&T talent agglomeration in cities and refine these policies for precision implementation,so as to enhance their effectiveness across different types of cities.These findings offer policy insights into maximizing the S&T talent agglomeration effect of innovation-driven policies,and hold significant implications for advancing S&T innovation and accelerating the development of new quality productive forces.
