Research On Cooperative Pricing Of Three Level Grain-Supply Chain

Food security has become an important focus of the world. Heilongjiang is a major grain producing areas in China. From Heilongjiang peasant surplus sales we can seen: When grain prices rise, farmers did not receive a reasonable profit ratio. That affects the enthusiasm of farmers to grow grain. It tries to change the disadvantage of grain producers and improve long-term competitive advantage for supply chain through the method of collaboration pricing and integration.The result shows that this paper has important theoretical and practical significance.First of all, analyzing the two-level supply chain of smallholders, the paper considers that the joint for smallholders to enter into the effective food supply chain and the integration collaboration rules. According to different joint for smallholders, the integration collaboration rules are different. It can enhance the integration and increase in structural stability between suppliers and Processors. It meet smallholders cooperative pricing conditions.Secondly, We study on cointegration relationship among price series of the round-grained rice and the polished round-grained rice, and analyzing long-term and short-term cointegration relationship between the price in the place of origin and the price processor respectively, and analyzing long-term and short-term of integration features and threshold cointegration features between the markets by the threshold cointegration model. We make price forecasts. Therefore, the market price mechanism is proposed among the nodes of the supply chain. The Collaboration Pricing strategy among the nodes of the there-level supply chain and government's intervening policies to integrate the supply chain are presented. It solves operational problems in the process of collaboration pricing. The study is a basis for the nodes enterprises in the supply chain deciding their cooperative pricing behavior.Finally, collaborative pricing between suppliers and processors is studied with the method of static game of complete information on the premise of government's subsidy for large suppliers building grain warehouse. The formula of optimal performance rate of contract is obtained. Operation conditions of collaborative pricing contract are summed up. It solves the inventory problems in the process of collaboration pricing. These conditions are helpful to guide making collaborative pricing contracts in grain supply chain between suppliers and processors, and shows that it is helpful to integrate grain supply chain if the government supports large suppliers for building warehouses.
