Research on the coordination of agricultural products' green supply chain has important practical significance for the development of agriculture. In this paper, the problem of the price and the green level of green supply chain of agricultural products is set up by game theory, three models including centralized decision-making, wholesale price contract and revenue sharing contract are analyzed. Results show that the agricultural products green level and the total income in the centralized decision-making model are the highest. The size of the green level and farmer’s profits in the decentralized decision model are determined by the relationship between the parameters of demand responsiveness to green SC’s own price, demand responsiveness to enterprise effort level and enterprise effort costs. The enterprise’s profits in the wholesale price contract model is higher.
