How does environmental regulation affect the double dividend for energy firms? Evidence from China's EPT policy

Changes in international markets and strict environmental regulations have challenged Chinese energy companies to reconcile sustainable and low-carbon development. There-fore, this paper focuses on 296 energy firms in China from 2011 to 2021 and uses the Difference-in-Differences (DID) method to explore the impact of China's environmental protection tax (EPT) reform on the dual dividend of energy firms from the perspective of resilience and CO2 emissions, and fully discusses the role of government subsidies and corporate social financing. This research finds that China's EPT reform can improve the resilience of energy firms while reducing CO2 emissions, and thus bringing a double dividend to energy firms. At the same time, government subsidies can enhance the decarbonization effect of EPT reform, but excessive subsidies can reduce the resilience of firms. In addition, the EPT reform can expand the scale of social financing for energy firms, helping them to realize a double dividend. The study's findings have important implications for the long-term low-carbon development of energy firms and provide a theoretical reference for China's EPT reform.& COPY; 2023 Economic Society of Australia, Queensland.

Automated summary

Changes in international markets and strict environmental regulations have challenged Chinese energy companies to achieve sustainable and low-carbon development. This study examines the impact of China's environmental protection tax reform on the resilience and CO2 emissions of energy firms, using a sample of 296 Chinese energy firms from 2011 to 2021. The results show that the reform can improve the resilience of energy firms while reducing CO2 emissions, and government subsidies and corporate social financing play important roles in this process.
