Environmental Information Disclosure,Corporate Green Exports,and the Improvement of Export Cost-Performance Ratio
Environmental information disclosure(EID)policies are a crucial element in building a comprehensive system for ecological and environ-mental governance.This paper initially explores the internal mechanisms through which environmental information disclosure influences firms'green exports.It then uses environmental information disclosure as a quasi-natural experiment and applies a Difference-in-Differences(DID)model to assess the net effect of this policy on firms'green export behavior.The results demonstrate that EID policies have a significant posi-tive impact on corporate green exports.This conclusion remains robust across various robustness checks,including alternative specifications,placebo tests,and the exclusion of concurrent policy shocks.Moreover,the effect of environmental information disclosure on green exports va-ries significantly depending on factors such as a firm's access to financing,trade type,and the level of industrial development.Mechanism tests show that while EID policies may discourage green exports by increasing environmental costs,they also stimulate innovation in green technologies and strengthen local market effects,thus boosting green exports.Further analysis reveals that EID policies not only enhance the quality of firms'green export products but also improve the cost-effectiveness of these exports.Therefore,the continuous improvement and en-hancement of the institutional framework for environmental information disclosure is a powerful tool for promoting global economic integration and fostering new competitive advantages in international markets.
