Abstract
Taking 257 heavily polluted A-share listed companies in Shanghai and Shenzhen from 2010 to 2017 as research samples, this paper investigates the impact effect and mechanism of environmental subsidies on enterprise environmental performance. The study found that environmental subsidies have a positive incentive effect on the environmental performance of heavy polluting enterprises, and its positive incentive effect mainly plays a role through three channels: promoting green technology innovation, increasing government environmental supervision and enhancing executives' environmental awareness. Further research shows that environmental subsidies have a more significant promoting effect on environmental performance in non-state-owned enterprises and enterprises with high degree of financing constraints and high level of risk taking. Based on the perspective of environmental benefits of micro enterprises, this paper not only provides direct evidence at the micro level for the implementation effect of government environmental subsidies, but also provides a reference basis for the government to improve the specific implementation path of environmental subsidies. At the same time, it also provides reference for the government to implement directional regulation and accurate implementation of policies according to the particularity of enterprises with different characteristics.
