Research on the Impact of Environmental Protection Tax on Enterprises'Green Technology Innovation under the Double Carbon Goal——Based on Empirical Data of A-share Listed Companies
Green technological innovation is an important way to promote sustainable economic development and to contribute to carbon peaking and carbon neutrality.Environmental protection tax,as an important tool of environmental regulation,plays an important role in enhancing green innovation of enterprises.This paper adopts the panel data of A-share listed companies from 2014 to 2022 and constructs difference-in-difference model to empirically test the effect of China's environmental protection tax on corporate green technology innovation.It is found that environmental protection tax has a significant contribution to the level of green technology innovation of heavily polluting listed companies;it has a significant promotion effect on the quantity of green technological innovation characterized by green utility model patents,but has a non-significant promotion effect on the quality of green technological innovation characterized by green invention patents.Examining the heterogeneity of firms,it is found that environmental protection tax mainly incentivizes the green technology innovation of state-owned and large-scale firms.Secondly,the environmental protection tax can enhance the level of green technological innovation by encouraging companies to increase their investment in R&D.The relevant research can provide theoretical reference for government departments to formulate relevant policies.
