环境规制对我国绿色技术创新效率的影响OA

Under the guidance of the new development concept,promoting the improvement of green technology innovation efficiency through environmental regulation tools is one of the key paths to achieving high-quality development.Based on the super-efficiency SBM model that can handle non-desired outputs,a re-gional quantitative assessment of green technology innovation efficiency in 30 provincial administrative re-gions of China(excluding Xizang,Hong Kong,Macao,and Taiwan regions)from 2012 to 2023 was conducted.Meanwhile,a fixed effect model was established to explore the impact of environmental regulation on green technology innovation efficiency in China,and to analyze the mediating effect of industrial structure optimiza-tion.The results show that the green technology innovation efficiency in China has shown a fluctuating up-ward trend during the study period,but the average efficiency has always been less than 1,with the efficiency ranking beingeastern>western>central;the impact of environmental regulation on green technology innovation efficiency shows a"U"shape;environmental regulation can indirectly affect green technology innovation effi-ciency through the dual mediating mechanisms of industrial structure rationalization and upgrading.According-ly,suggestions are proposed in terms of strengthening regional cooperation,tailoring environmental regulation policies to local conditions,and optimizing industrial structures,in order to improve green technology innova-tion efficiency and accelerate the process of high-quality development of China's green and low-carbon econo-my.
