摘　　要：建立了一个包含人才集聚正外部性和负外部性的多区域、两要素、三部门的创新增长模型研究地方品质对城市创新的影响,理论模型结果显示:在人才集聚正外部性较强时,地方品质会提升城市创新能力,而人才集聚负外部性则会减弱这一影响。利用281个地级市2013—2021年每两年的数据进行实证分析,结果显示:人才集聚水平对地方品质与城市创新的关系具有负向调节作用;进一步分析表明,在对城市创新的影响中,人才集聚的正外部性与地方品质具有协同作用,而人才集聚的负外部性与地方品质具有替代作用;另外,地方品质对城市创新能力的影响具有非线性特征,在人力资本水平中等、工资水平高和人口密度适中的地区发挥作用最大。因此,地区尤其是中等规模的城市在打造城市品质时,应提供足够的空间激发人才集聚的正外部性,同时缓解人才集聚带来的负外部性。A multi-regional,two-factor,three-sector innovation growth model that incorporates both the positive and negative externalities of talent agglomeration was established to study the impact of local quality on urban innovation.The theoretical model shows that when the positive externalities of talent aggregation are strong,local quality has a positive impact on urban innovation,while the negative externalities of talent aggregation weaken this effect.Subsequently,an empirical analysis was conducted using data from 281 prefecture-level cities every two years from 2013 to 2021.The results show that the level of talent aggregation has a negative moderating effect on the relationship between local quality and urban innovation;further analysis indicates that in the impact on urban innovation,the positive externalities of talent aggregation have a synergistic effect with local quality,while the negative externalities have a substitutive effect;additionally,local quality has a non-linear impact on urban innovation capabilities,playing the greatest role in areas with moderate levels of human capital,high wage levels,and moderate population density.Therefore,regions,especially medium-sized cities,should provide ample space to stimulate the positive externalities of talent aggregation while mitigating the negative externalities brought about by talent aggregation when crafting urban quality.
