城市品质、人才集聚与城市创新

Urban Quality, Talent Concentration and Urban Innovation

基于内生增长理论构建人才集聚创新增长模型,探讨了城市品质、人才集聚和城市创新之间的作用机制。选取2008—2020年我国277个地级及以上城市的面板数据进行实证检验,结果表明:城市品质通过吸纳人才集聚,显著提升了城市创新水平。异质性分析表明:相较于超大城市和特大城市,大城市和中小城市的创新增长对城市品质的依赖性更强;胡焕庸线以东地区的城市品质对城市创新的边际贡献大于胡焕庸线以西地区;城市群内的城市品质对城市创新的促进作用更大。因此,可通过打造优良的城市品质、差异化实施城市品质驱动策略、创新引才机制等途径提升城市创新水平。

Based on the endogenous growth theory, an innovative growth model of talent agglomeration is constructed, and the mechanism among urban quality, talent agglomeration and urban innovation is discussed.The panel data of 277 prefecture-level cities and above in China from 2008 to 2020 are selected for empirical testing, and the results show that urban quality significantly improve the level of urban innovation by absorbing talent agglomeration.The heterogeneity analysis shows that compared with super-megacities and megacities, the innovation growth of large cities and small and medium-sized cities is more dependent on urban quality.The marginal contribution of urban quality to urban innovation in the area east of the Huanyong Line is greater than that of the area west of the Huanyong Line.The quality of cities in urban agglomerations plays a greater role in promoting urban innovation.Therefore, the level of urban innovation can be improved by creating excellent urban quality, differentiating the implementation of urban quality-driven strategies, and innovating talent introduction mechanisms.
