摘　　要：基于2007—2022年中国地级市面板数据,视国家创新型城市建设为一项准自然实验,选用多期DID方法(Time-varying DID),实证分析创新要素集聚视角下国家创新型城市建设对新质生产力的影响效应,结果发现,国家创新型城市建设能够显著增强新质生产力,且该结论通过工具变量法等系列稳健性检验后仍然成立。机制检验表明,人才创新要素集聚、技术创新要素集聚及资本创新要素集聚是国家创新型城市建设赋能新质生产力的有效路径。异质性分析表明,在数字基础设施水平高、政府干预程度低的城市中,国家创新型城市建设对新质生产力的促进效应更加明显,该研究结论为充分发挥国家创新型城市建设的创新要素集聚效应,探寻增强新质生产力的实现路径提供了经验证据和决策参考。Based on panel data from prefecture level cities in China from 2007 to 2022,this study regards the construction of national innovative cities as a quasi natural experiment and selects the Time Varying DID method to empirically analyze the impact of national innovative city construction on new quality productivity from the perspective of innovation factor agglomeration.The results showed that the construction of national innovative cities can significantly enhance new quality productivity,and this conclusion still holds after a series of robustness tests such as instrumental variable method.Mechanism testing shows that the agglomeration of talent innovation factors,technology innovation factors,and capital innovation factors is an effective path for the construction of national innovative cities to enhance new quality productivity.Heterogeneity analysis shows that in cities with high levels of digital infrastructure,low levels of government intervention,and geographical advantages,the promotion effect of national innovative city construction on new quality productivity is more significant.In addition,the construction of national innovative cities has a positive spatial spillover effect on the new quality productivity of surrounding areas.The research conclusion of this article provides empirical evidence and decision-making reference for fully leveraging the agglomeration effect of innovative elements in the construction of national innovative cities and exploring the implementation path of enhancing new quality productivity.
