地方品质、企业集聚行为与城市创新能力

Local Quality,Enterprise Agglomeration Behavior and Urban Innovation Capacity

从企业集聚行为视角出发,利用2010~2019年全国284个城市面板数据,探讨地方品质对城市创新能力的影响作用及其内在机制。研究结果表明,地方品质对城市创新能力有明显的促进作用。这一结论在缓解内生性及多种稳健性检验后依然成立。中介效应检验发现,企业集聚在地方品质驱动城市创新中发挥着中介作用,地方品质能够通过吸引企业集聚来影响城市创新。异质性分析表明,相较于经济发展水平较高的大城市以及中心城市,经济发展水平较低的中小城市和非中心城市的地方品质对城市创新能力的促进作用更显著。因此,城市特别是中小城市应大力推进地方品质建设,加快推进产业集群发展,发挥集聚经济的创新能力,促进城市创新能力提升。

From the perspective of enterprise agglomeration behavior,this paper uses the panel data of 284 cities in China from 2010 to 2019 to explore the influence of local quality on urban innovation ability and its internal mechanism.The results show that local quality has a significant role in promoting urban innovation ability.This conclusion is still valid after alleviating endogeneity and multiple robustness tests.The mediation effect test finds that enterprise agglomeration plays a mediating role in driving urban innovation through local quality.That is,local quality can influence urban innovation capability by attracting enterprise agglomeration.Heterogeneity analysis shows that compared with large cities and central cities with higher economic development level,the local quality of small and medium-sized cities and non-central cities with low economic development level has a more significant effect on urban innovation ability.Therefore,cities,especially small and medium-sized cities,should vigorously promote local quality construction,accelerate industrial cluster construction,leverage the innovative capabilities of agglomeration economy,and promote urban innovation capacity.
