Currently, China is in a critical period of coordinating development and environmental governance, and carbon trading policies are advancing steadily. Against this background, whether carbon trading policies can promote the improvement of enterprises’ green total factor productivity has become a hot issue. Based on this question, this study verifies and analyzes through a quasi-natural experiment using the difference-in-differences method, and explores targeted suggestions and countermeasures, aiming to provide a reference for relevant personnel and jointly contribute to the realization of the “dual carbon” goals and the promotion of green development.Carbon trading policies,Green Total Factor Productivity (GTFP),Green innovation capability,Financing efficiency,Difference-in-differences method
