Industrial Collaborative Agglomeration,Technological Innovation and Efficiency of Green Economy from New Quality Productivity:A Mediation Effect Analysis based on Spatial Econometric Model
Based on provincial-level data from 2009 to 2022,this paper combines spatial econometric model and media-tion effect analysis to investigate the influence of industrial collaborative agglomeration enabled by new quality produc-tivity on green economy efficiency and the mediating role of technological innovation.Compared with the traditional mediation effect analysis,this method which considered spatial effect can correct the errors caused by ignoring spatial correlation,and identify the influence relationship between variables more accurately through spatial effect decomposi-tion.The results show that,firstly,the efficiency of green economy among provinces in China has significant spatial and intertemporal interaction effects.Secondly,the collaborative agglomeration has a significant promoting effect on the ef-ficiency of the region itself and others in a short term.While in a longer term,excessive agglomeration may produce"congestion effect".Thirdly,the agglomeration has a significant negative impact on other regions'technological innova-tion in a short term,indicating that the influence on technological innovation may have"congestion effect"and"path dependence effect".Fourthly,there is a significant difference between the traditional mediation effect analysis and the spatial econometric model-based mediation effect analysis.Technological innovation does not have a"mediation effect"under the traditional method,but the spatial econometric model-based mediation effect analysis shows that technological innovation has a"partial intermediary effect"in the impact of industrial collaborative agglomeration on the green econo-my efficiency.
