| Abstract: Based on the panel data of China's industrial industry, this paper uses the DEA model to measure the efficiency of green technology innovation in various industries, compares and analyzes the efficiencies at the two stages of green technology R&D and the conversion of green technology. Finally, it exploits the Tobit model to evaluate the efficiency of green technology innovation in its empirical study on the influencing factors. The research finds that the overall efficiency of green technology innovation in China's industrial industry is on the rise with yet great gaps between industries, that factors such as average enterprise size, degree of marketization, degree of opening to the outside world, and intensity of environmental regulations are the main forces that promote the improvement of the efficiency of green technology innovation, and that the impact of the technology environment on the efficiency of green technology innovation works mainly at the stage of the green technology R&D, while the green technology transformation stage is mainly affected by the market environment and policy environment. To further improve the efficiency of green technology innovation, we need to increase investment in green technology innovation, optimize resource allocation, and create a good environment for innovation. |
