In this paper, we use the two-tier market model to discuss the relationship between the stakeholders such as grain farmers, private grain dealers and state-owned grain purchase enterprises respectively in the grain purchase market, and analyze the comprehensive effect of the grain minimum purchase price policy. The results show that reducing market transaction costs and improving transaction efficiency are the keys to coordinating the interests of all main actors in the grain purchasing market and stabilizing the market order. The lowest purchase price policy of grain can achieve better economic and social benefits. This research and its conclusion are of great practical significance to the construction of China’s grain market and the guarantee of national food security.
