Under the requirements of the era of "Double Carbon" goal and high-quality energy development, it is necessary to adhere to the coordinated development of "two-wheel drive" of scientific and technological innovation and institutional innovation. Using the coupling coordination degree model to explore the coupling coordination development level of green low-carbon scientific and technological innovation and institutional innovation, the data of 30 provinces in China was selected, and the regional agglomeration effect was analyzed. The results show that there is a strong coupling interaction between scientific and technological innovation and institutional innovation in China's green and low-carbon field, but the overall level is not high and local imbalance. Countermeasures and suggestions are put forward to promote the coupling and coordinated development of "two-wheel drive" innovation in the green and low-carbon field.
