Methods: A double difference model was constructed. Based on the data on green bond issuance from 2018 to 2023, private enterprises supported by discount interest were selected as the treatment group to quantify the changes in financing costs before and after the implementation of the policy. Results: The discount policy significantly reduced the marginal cost of financing for private enterprises by an average of about 37 basis points, and the effect was more significant in small and micro enterprises and environmental protection oriented industries. The compression of credit premium and the improvement of market transaction activity are the main mechanisms. Conclusion: The green discount policy has a significant cost mitigation effect and credit enhancement value. We should strengthen the system linkage and improve the structure and sustainability of policy incentives.
