摘要
该文基于2012—2022年中国283个城市面板数据,采用面板回归模型、中介效应模型实证检验了创新要素集聚对新质生产力发展的影响效应与作用机制.实证结果表明:创新要素集聚对新质生产力发展具有显著正向影响,且产业结构升级与技术进步在创新要素集聚对新质生产力发展的影响中发挥中介作用.区域异质性检验发现东部地区与中部地区创新要素集聚显著促进新质生产力发展,且中部地区驱动效应更强,但西部地区不显著.“胡焕庸线”东南侧城市促进作用显著而西北侧不显著.创新要素集聚水平异质性检验发现高集聚水平城市促进作用显著,而低集聚水平城市促进作用不显著.据此,从促进创新要素的高效集聚、强化创新要素集聚的技术效应与结构效应方面为促进区域新质生产力发展提出政策建议,研究结论对于探索中国新质生产力发展路径具有重要的理论与现实意义.
Based on the panel data of 283 cities in China from 2012 to 2022,the panel regression model and mediation effect model are used to empirically test the effect and mechanism of innovation factor agglomeration on the development of new quality productivity.The empirical results show that innovation factor agglomeration has a significant positive impact on the development of new quality productivity,and industrial structure upgrading as well as technological progress play a mediating role in the impact of innovation factor agglomeration on the development of new quality productivity.The test of geographic heterogeneity finds that innovation factor agglomeration significantly promotes the development of new productivity in the eastern region and central region,and the driving effect is stronger in the central region,but not in the western region.The cities in the southeast side of the Hu Huanyong line promote significantly but not in the northwest side.The test of heterogeneity in the level of innovation factor agglomeration reveals that cities with high levels of agglomeration have a significant promotion effect while cities with low levels of agglomeration have a non-significant promotion effect.Accordingly,the study proposes policy recommendations to promote the development of regional new quality productivity in terms of promoting the efficient agglomeration of innovation factors and strengthening the technological and structural effects of innovation factor agglomeration,and its conclusions are of great theoretical and practical significance for exploring the path of China's new quality productivity development.
