绿色技术创新、新质生产力与新能源汽车产业链现代化OACHSSCD

With the further deepening of the new development concept and the systematic promotion of the"double carbon goal",new energy vehicles have become the most dynamic strategic emerging in-dustry.Green technology innovation is an important way to create eco-friendly new processes,technolo-gies and modes with low energy consumption,low emissions and low pollution,providing key support for the modernization of the new energy vehicle industry chain.The disruptive technologies brought by green technology innovation give rise to new quality productivity and indirectly promote the moderniza-tion of the new energy vehicle industry chain.Based on China's provincial panel data from 2016 to 2023,the study empirically examines the promotion effect of green technology innovation on the mod-ernization of the new energy vehicle industry chain using a two-way fixed-effects model,and explores the mediating effect of new quality productivity in the promotion effect.The empirical results show that green technological innovation can significantly promote the modernization process of the new energy automobile industry chain;green technological innovation can accelerate the formation of new quality productivity,and then provide modern support for the new energy automobile industry chain.Moreover,the relationship between green technology innovation and the modernization of new energy automobile industry chain has a double threshold feature.
