Abstract: At present, the environmental problems caused by the excessive consumption of energy and resources in China are rapidly becoming prominent. Improving energy efficiency is a key to promote the green transformation of industry, ecological construction, and high-quality economic development. Based on super-SBM and the dynamic panel threshold model, this paper focuses on the heterogeneity of green transformation among industrial sectors in China, and introduces innovation effect as threshold variable to further explore the impact of energy intensity on industrial green transformation. The results show that the level of green industrial transformation in China is low, there is a large space for development, and the industry heterogeneity is significant, showing a relatively significant trend of fluctuation during the transformation. It is worth explaining that energy intensity has an obvious innovation effect and heterogeneous threshold effect on China’s industrial green transformation. The low level of innovation effect is not conducive to reducing energy intensity and driving industrial green transformation. With the improvement of innovation effect level and breaking through the “critical point”, energy intensity has played an effective role to a certain extent, and then promoted the green transformation of industry.
