The research shows that: (1)grace period sensitivity coefficient has positive effects on the green marketing level and the profits of supply chain members. (2)Credit payment will cause premium phenomenon for products, but under certain conditions, the credit payment strategy can improve the profits of supply chain members and the green marketing level at the same time, and induces a win-win situation in both economic and environmental performances. (3)When the processing fee rate is high, if the credit term coefficient is small, the immediate payment strategy will be the best. If the credit term coefficient is moderate, the installment strategy will be the best. Otherwise, the minimum repayment strategy will be the best. The minimum repayment strategy will be the best if the processing fee rate is low and the credit period is small, otherwise the immediate payment strategy will be the best. On this basis, a combination contract of cost sharing and revenue sharing is designed for two credit payment models to coordinate the supply chain.
