As an effective regulatory tool, environmental information disclosure is significant in promoting the green upgrading of industrial structures and achieving green transformation of enterprises. In order to explore the impact mechanism of environmental information disclosure on corporate sustainability performance, this paper constructs a two-way fixed-effect model using balanced panel data of Chinese A-share listed manufacturing companies from 2015 to 2020. We find that environmental information disclosure significantly impacts green innovation, thereby improving corporate sustainability performance. Furthermore, financing constraints inhibit the impact of environmental disclosure on sustainability performance, while female directors have only symbolic effect. The reliability of the paper’s findings is verified by replacing the dependent variable and introducing instrumental variables. Heterogeneity analysis shows that the effect of environmental information disclosure on corporate sustainability performance is more substantial among non-state and eastern and heavily polluting enterprises. Comprehensive analysis from the financing perspective shows the differences in the moderating effects of debt and equity financing regarding the impact mechanism. This study enriches the theory of green innovation and provides financing strategies for enterprises to achieve green transformation, as well as suggestions for improving the government environmental information disclosure system.

Green credit policy (GCP), as one of the key financial instruments to achieve ’carbon peaking’ and ‘carbon neutrality’ targets, provides capital support for the green development of enterprises. This paper explores the impact mechanism of GCP on the sustainability performance of heavily polluting enterprises (HPEs) from the perspectives of technological innovation level (TIL) and credit resource allocation (CRA), using panel data for Chinese A-share listed manufacturing companies from 2010 to 2015 to construct a propensity score matching and differences-in-differences (PSM-DID) model. We find that GCP has a causal effect on corporate sustainability performance (CSP). Although GCP significantly improves CSP, there is no long-term effect. Heterogeneity analysis shows that the relationship between GCP and CSP is only significant in non-state-owned enterprises and in eastern and low-market-concentration enterprises. Mechanism tests indicate that GCP stimulates HPEs to invest more in technological innovation and thereby improves CSP through the innovation compensation effect; the credit constraint and information transfer effects caused by GCP reduce the credit resources available to HPEs but have a significant forced effect on CSP. This paper enriches the study of the economic consequences of GCP and provides implications for stakeholders to improve the green financial system and achieve green transformation of HPEs.

As a formal environmental regulation, environmental tax is important for the green upgrading of industrial structure. In order to explore the impact mechanism of environmental tax on corporate financial performance, this paper constructs a difference-difference (DID) model with two-way fixed effects based on financial data of Chinese A-share manufacturing listed companies from 2015 to 2019. We have found that environmental taxes contribute directly and significantly to the improvement of financial performance and that technological innovation, in some degree, produces mediating effect. Financing constraints not only negatively moderate the relationship between environmental taxes and technological innovation; they also inhibit the impact of technological innovation on financial performance and have a moderate mediating effect as part of the indirect influence. In the heterogeneity analysis, the direct effect is more significant among State-owned enterprises (SOEs) and eastern enterprises, and the moderating effect of financing constraints is more significant among non-SOEs and eastern enterprises. This paper advances the understanding of economic consequences of environmental tax levies from the perspective of property and regional heterogeneity. It provides empirical evidence in support of the applicability of Porter’s hypothesis in China and makes suggestions for the optimization of environmental policy and improvement of financial performance of enterprises.
