Impact of Environmental Rights Trading on Green Innovation of Enterprises:From the Perspective of Sulfur Dioxide Emission Trading Policy
In this paper,the pilot trading policy of sulfur dioxide emission is applied as a quasi-natural experiment of the environmental rights trading market,combined with the data of China's industrial enterprises from 1998 to 2021.The results show that sulfur dioxide emission trading policy can promote enterprises'green innovation,and the conclusion is still valid after a series of robust tests and endogeneity treatments.The core mechanism of the policy to encourage green innovation is to promote the patent division among different types of enterprises,which has a more significant promoting effect on clean enter-prises than hybrid enterprises and further induces the transfer and licensing of green patents from clean enterprises to hybrid enterprises.Additionally,knowledge spillover is an important basis for the effective play of this mechanism.This study shows that the environmental rights trading market can stimulate enterprises'green innovation by promoting patent division.
