Taking the Use-Energy-Right transaction system of China in 2017 as a quasi natural experiment, this paper selects 2015-2018 A-share listed industrial enterprises as a sample, and uses the differences-in-differences method to empirically test the impact of the Use-Energy-Right transaction system on enterprise green innovation. The results show that:①The Use-Energy-Right transaction system policy significantly induces the green invention patent innovation of enterprises in the pilot areas, rather than the green utility model patent innovation.②The induced effect of the policy is stronger in non-state-owned enterprises or enterprises with high transfer cost or low degree of financing constraint. The conclusion of this paper means that while establishing a unified Use-Energy-Right trading market in China, it is necessary to further accurately pinpoint the characteristics of energy use enterprises and formulate the differentiated supporting policies for the Use-Energy-Right transaction.
