Green power trading is an institutional innovation proposed by China to promote green and sustainable development. This policy aims to relieve the serious debt pressure of renewable energy generation enterprises, thus laying the foundation for achieving carbon reduction targets. This paper empirically examines the role of green power trading by constructing the difference-in-differences (DID) model. Our findings indicate that green power trading significantly reduces the debt levels of policy-covered generation enterprises. This effect is more pronounced for state-owned enterprises, companies with better ESG performance, companies in regions with higher degree of marketization and companies specializing in renewable energy power generation. Further research discusses the impact mechanism of green power trading in terms of external and internal environmental channels. We find that a strong green development atmosphere, especially the external atmosphere, will significantly reinforce the weakening effect of green power trading on corporate debt. Our research provides empirical evidence for the success of green power trading policy in its pilot phase. • Green power trading significantly alleviates the policy-covered firms' debt burden. • The role of green power trading presents heterogeneity in enterprise characteristics. • A better regional environment for green growth can stimulate the effect of green power trading.

Green credit is a major policy innovation to guide enterprises to participate in environmental governance actively. This study uses the data of Chinese A-share listed companies from 2007 to 2016, takes the green credit guideline (GCG) issued in 2012 as a quasi-natural experiment, and uses a difference in difference (DID) model to test the effect of GCG on the enterprises' export green-sophistication (EGS) and its internal and external mechanisms. The study finds that GCG improves enterprises' EGS and research and development (R&D) investment is the intermediation channel for GCG to affect EGS. Results of heterogeneity analysis show that the role of GCG in promoting EGS is significantly reflected in enterprises that the government does not subsidize, enterprises in areas with a low degree of financial marketization development, state-owned enterprises, and enterprises with a high degree of equity incentive. • GCL can significantly improve enterprises' EGS. • Firms' research and development expenditure have a positive mediating effect. • The improvement effect of GCL on EGS is stronger in state-owned firms.

Despite increasing evidence documenting the role of the outgoing audit of natural resources (OANRA) in environmental governance and enterprise innovation, little is known about its impact on enterprises' total factor productivity (TFP). To address this question, we treat the OANRA policy launched in 2014 in China as a quasi-natural experiment. We adopt a difference-in-differences-in-differences (DDD) method that exploits three-dimensional variations: city (i.e., OANRA cities versus non-OANRA cities), industry (i.e., more polluting industries versus less polluting ones), and year (i.e., before and after the OANRA policy). Employing a dataset of Chinese industrial listed companies from 2012 to 2019, we reveal that after the OANRA implementation, enterprises' TFP in more polluting industries of OANRA cities decreases by 4.0%. Our mechanism analysis shows that the OANRA restrains the TFP by reducing the financing scale of enterprises and increasing environmental investment of governments. Further, the heterogeneity analysis finds the inhibitory effect of the OANRA is more prominent in large-scale and state-owned enterprises, as well as enterprises located in eastern, low fiscal pressure, and high pollutant emission cities. Our findings provide support for the neoclassical economics hypothesis that the OANRA increases enterprises' compliance costs and decreases their productivity. • We study the relationship between the outgoing audit of natural resources assets (OANRA) and enterprise productivity. • We exploit the difference-in-differences-in-differences analyses and an instrumental variable design. • Evidence suggests enterprises' TFP in more polluting industries of OANRA cities decreases by 4.0%. • Evidence shows the OANRA restrains enterprises' TFP by reducing financing scale and increasing environmental investment. • Our study reveals the possible negative economic impacts of the OANRA and provides recommendations for policy optimization.

Strict environmental governance urges firms to implement higher sustainable production requirements and environmental standards for export products, making it challenging for firms to maintain export competitiveness. This study constructs firm-product level markups as the measure of export competitiveness using microdata of millions of observations from Chinese industrial firms. It then empirically investigates the impact of environmental regulations on those firms' export competitiveness. The empirical study finds: 1) environmental regulations have significantly increased the markups of Chinese firms' export products, indicating that firms' export competitiveness is enhanced, verifying the validity of the Porter Hypothesis. 2) Environmental regulations have a greater effect on increasing the markups of non-core products than that of core products. 3) Environmental regulations have significantly increased the markups for private-owned firms, foreign-invested firms, and firms in the eastern region, but not for state-owned and non-eastern firms. 4) Environmental regulation mainly enhances firms' export competitiveness mainly through the TFP channel. Moreover, a series of robustness tests support the empirical results. This research recognizes the positive achievements and benefits of China's environmental governance. It recommends that the Chinese government strengthen the supervision of state-owned enterprises and help enterprises in economically underdeveloped areas overcome the challenges brought by environmental regulation. • The impact of environmental regulation on export competitiveness is discussed. • Export competitiveness is measured by a new indicator: firm-product level markups. • Environmental regulations have significantly increased the export competitiveness of Chinese firms. • Environmental regulation enhances firms' export competitiveness mainly through the TFP channel.
