As the combination of green development and innovation-driven strategies,green innovation has become an important strategic goal of China's green transformation and development.Based on the super-efficiency SBM(slack-based measure)model of undesired output,the measurement and evaluation of China's provincial green innovation efficiency from 2012 to 2021 is evaluated,the Dagum Gini coefficient is used to analyze the difference of China's green innovation efficiency,and the Tobit regression model is used to analyze the influencing factors.The results show that China's overall green innovation efficiency is gradually improving,but the overall Gini coefficient shows a"W-shaped"trend,and the level of economic development,market competition intensity,foreign development level and government support can significantly improve China's green innovation efficiency.According to the research results,countermeasures and suggestions are put forward to improve the efficiency of green innovation and reduce regional differences in China.
