The Impacts and Mechanisms of Corporate Social Responsibility Disclosure on Corporate Exports: With Reference to the Moderating Effect of Environmental Regulation

Corporate social responsibility (CSR) disclosure plays a pivotal role in mitigating “blue” (labor standard) and “green” (environmental standard) trade barriers, optimizing the foreign trade ecosystem, fostering sustainable development of export-oriented enterprises, and advancing societal welfare objectives—all critical to maintaining high-quality social order in China. Grounded in institutional and strategic management theories, this study systematically investigates the effects of CSR disclosure on corporate export performance, focusing on mediating and moderating mechanisms, and conducts rigorous empirical testing using comprehensive firm-level CSR disclosure data from Chinese listed companies. The results reveal the following key findings: (1) CSR disclosure positively influences corporate exports; (2) enterprise financing capacity and innovation output serve as dual mediating mechanisms, through which CSR disclosure enhances export performance by improving access to external capital and stimulating product/service innovation; (3) environmental regulations amplify the export-promoting effect of CSR disclosure, indicating that institutional environmental constraints incentivize firms to leverage disclosure as a strategic response to global sustainability demands; (4) heterogeneity analysis reveals that large enterprises derive the strongest export benefits from CSR disclosure, followed by medium-sized and small enterprises; and (5) private enterprises exhibit significantly greater export gains from CSR disclosure compared to state-owned enterprises. These results underscore the context-specific and multi-dimensional nature of CSR disclosure’s impact on exports, highlighting how firm size and ownership structure shape the efficacy of disclosure strategies in global markets. This study contributes to both academic literature on corporate sustainability and practical policy by demonstrating how strategic CSR disclosure can serve as a tool for overcoming institutional barriers and enhancing international competitiveness.
