We investigate the impacts of anticipated government environmental audits (GEAs) on firm productivity. We use a 2009 policy set forth by China’s National Audit Office that required GEAs of local governments as an exogenous event to examine the effect of the policy announcement on firms’ total factor productivity (TFP). Our difference-in-differences tests indicate that TFP in heavily polluting firms improved more than other firms’ TFP after the announcement of the policy. We also find that to raise TFP, firms engage in green invention patents or receive government environmental subsidies. In addition, our cross-sectional analysis suggests that firms in regions where governments have strong environmental enforcement or that are in the eastern regions of China increase TFP more.

The pilot carbon emission trading schemes (ETSs) of China were created to combat climate change in a cost-effective and economically efficient manner, and their potential impact on regulated firms has drawn increasing attention. This study is conducted to provide empirical evidence on the effect of China’s pilot ETSs on firm-level financial performance during the period from 2008 to 2017. The empirical results show that the ETS pilots have a positive impact on firms’ profitability and value, and a negative impact on operational costs. We also find that the ETS pilots improve total factor productivity (TFP) but that changes in technology have an indirect suppressing effect on the relation between the ETS and short-term financial performance, providing support for the weak version of the Porter Hypothesis. Further, we show that the carbon emission price has a negative impact on firms’accounting-based performance but increases firms’ market value. Finally, we find evidence that, in contrast to state-owned enterprises (SOEs), non-SOEs do not experience significant improvements in their financial performance, led by the ETS pilots. Our findings have policy implications for firms’sustainable development and the transition to a low-carbon economy.
