Based on the panel data of 30 provinces in China from 2007 to 2019, this paper investigates the impact of green technology innovation on carbon intensity. Firstly, this paper studies the dynamic evolution and temporal and spatial pattern of China's provincial green technology innovation and carbon intensity. On this basis, the nonlinear spatial Durbin model (SDM) is used to explore the impact of green technology innovation on carbon intensity, and the relevant variables are controlled. The results show that there is a significant spatial agglom...
