本文旨在探究产业链与创新链耦合协调对新质生产力的影响。基于2012~2023年我国30个省份的面板数据,构建评价指标体系,并采用基准回归、稳健性检验、异质性分析和机制检验等方法展开研究。结果表明,产业链与创新链耦合协调对新质生产力具有显著的正向促进作用,且该结论具有稳健性。研究显示存在明显的地区异质性特征,其中东部地区促进作用最为显著。创新投入和产业升级在传导路径中均具有显著的中介效应,且产业升级的间接效应更为突出,区域GDP对新质生产力存在抑制性调节作用。基于研究结论,建议制定差异化区域政策、优化创新投入机制、推动产业升级转型,从而促进新质生产力发展。This paper aims to explore the impact of the coupling and coordination between the industrial chain and the innovation chain on new quality productivity. Based on the panel data of 30 provinces in China from 2012 to 2023, an evaluation index system was constructed, and methods such as benchmark regression, robustness test, heterogeneity analysis, and mechanism test were used for research. The results show that the coupling and coordination between the industrial chain and the innovation chain have a significant positive promoting effect on new quality productivity, and this conclusion is robust. The research shows that there are obvious regional heterogeneity characteristics, among which the promoting effect in the eastern region is the most significant. Innovation input and industrial upgrading both have significant mediating effects in the transmission path, and the indirect effect of industrial upgrading is more prominent. Regional GDP has an inhibitory moderating effect on new quality productivity. Based on the research conclusions, it is recommended to formulate differential regional policies, optimize the innovation input mechanism, and promote industrial upgrading and transformation, so as to promote the development of new quality productivity.
