新質生産性はグリーンイノベーションの質と量を改善するか：産業協調的集積の調整効果に基づく

The emergence of new quality productivity has injected new momentum into green innovation. Exploring and identifying the intrinsic connection between the two is of great significance for the realization of economic green transformation in China and the construction of an innovative country. This study, based on a resource perspective, followed the theoretical framework of the development path of new quality productivity characterized by "technological innovation-structural transformation-element integration." It analyzed and tested the mechanism by which new quality productivity empowers green innovation from both the "quantity" and "quality" dimensions, as well as the moderating role played by synergistic agglomeration of productive service industries and high-tech industries （"industrial collaborative agglomeration"）. The study revealed that： ① New quality productivity could promote the "simultaneous increase in quantity and quality" of green innovation, with a greater effect on the quantity of green innovation. ② The promotional effect of new quality productivity on the "quantity" and "quality" of green innovation showed a nonlinear characteristic of diminishing marginal effect under the moderating influence of industrial collaborative agglomeration. Further group threshold regression indicated that the moderating role of industrial collaborative agglomeration had regional heterogeneity, with new quality productivity being more effective in achieving a "simultaneous increase in quantity and quality" of green innovation in the central and western regions compared to that in the eastern region. ③ Spatial econometric analysis showed that new quality productivity could generate positive spatial spillover effects, effectively enhancing the quantity of green innovation in neighboring areas, but its positive effect on the quality of green innovation in neighboring areas was not yet significant. Therefore, in future construction, each region must pay attention to the improvement of the quality and social benefits of green innovation, fully stimulate the potential of new quality productivity, formulate differentiated policies for the characteristics of industrial collaborative agglomeration in different regions, optimize the innovation ecosystem, and set up regional cooperation mechanisms, so as to form a green economic development network.
