The new normal economic development stage poses new challenges to China’s low-carbon transformation, which objectively requires enterprises to innovate their emission reduction behaviors, thus giving birth to the thirdparty authorization of low-carbon patented technologies. Technology licensing can effectively realize the rapid flow of low-carbon emission reduction technologies from the third party to enterprises in the industry, reduce the emission reduction costs of enterprises and promote technological progress. Using evolutionary game theory, this paper discusses whether oligarchs buy low-carbon patented technology to reduce the generation cost and improve the competitiveness of enterprises. It is found that there is no evolutionary stable point when the transfer fee of low-carbon technology of third-party institutions is high; When the low-carbon technology transfer fee is appropriate, there are three evolutionary stable points (1,0), (1,1) and (1,1); When the patent transfer fee is low, there are two evolutionary stability points (0,0) and (1,1). In addition, considering the existence of a strong enterprise, this paper studies the impact of the low-carbon technology licensing fee of a third-party institution on the purchase decisions of the two enterprises. Finally, according to the evolution trend of equilibrium results, relevant management implications are given.
