Abstract: As an essential reform of China’s environmental regulatory policy, the environmental protection tax reform achieves a smooth transition from the emission fee system to the environmental protection tax system according to the principle of tax burden leveling. With the quasi-natural experiment of the introduction of the Environmental Protection Tax Law, this paper examines the effect of environmental protection tax reform on total factor productivity of heavily polluting firms using a difference-in-difference approach based on empirical evidence of Chinese listed companies from 2015 to 2020. It is found that environmental tax reform can significantly increase the level of total factor productivity of heavily polluting firms, and the results remain robust to robustness tests using the OP method, the GMM method to re-measure the total factor productivity of heavily polluting enterprises and the use of different industry classification criteria, with the mechanism of action mainly coming from the technological innovation effect and capital allocation optimization. In addition, the effect of environmental tax reform on total factor productivity of heavily polluting firms is heterogeneous across regions and industries, with the total factor productivity of firms in heavily polluting industries in the eastern region being least affected by environmental tax policies and state-owned enterprises with heavy property rights structures being most affected by environmental tax reform.
