Research On Network Game And Cooperation Mechanism Of Agriculture Products Suppiy Chain Under The “Agriculture-supermarket Jionting” Mode

Under the current rapid urbanization in our country, the farmers enterprises obtained the rapid expansion and penetration in urban and rural areas, the “Agriculturesupermarket Jointing” mode as the optimization of agricultural products supply chain, improve the agricultural product circulation pattern, and ease the “hard to sell and buy expensive” phenomenon of the agricultural products, However, under the “Agriculturesupermarket Jointing” mode, the “product, supply, sell” activities that among agricultural communes, distribution centers, supermarkets and other enterprises were embedded in their social and economic networks, and formed a wider interwoven agricultural products supply chain network which evolved from the cooperative relationships, meanwhile, the network continually appears supply-demand imbalance, unreasonable profit allocation and other issues. Therefore, this paper tries to offer a profound theoretical analysis on the cooperation mechanism and profit allocation mechanism of agricultural products supply chain network by applying the network game theory and incorporating the two typical “Agriculture-supermarket Jointing” modes.Firstly, for the “agricultural+supermarkets” mode, this paper studies a two-stage agricultural products supply chain network composed of m agricultural communes and n supermarkets, by constructing the network game profit model, we give profit allocation of the Myerson value; under the agricultural products supply chain networks with different structure forms, we investigate the stability of the Myerson value, and give parameter relationships and corresponding conditions to ensure this stability.Then, the “gricultural commune+distribution center+supermarket” mode is the extension of the “agricultural+supermarkets” mode in the aspect of the optimization of agricultural products supply chain, this paper analyzes a three-stage agricultural products supply chain network consisted of m agricultural communes, l distribution centers and n supermarkets, by constructing the network game profit model, we present an nonempty core to ensure the stability of agricultural products supply chain network. For a special agricultural products supply chain network, this paper investigates the stability of Myerson value, and also gives parameter relationships and corresponding conditions to safeguard the stability.Finally, taking the “Agriculture-supermarket Jointing” mode of Yonghui Supermarket as an example, this paper gives a numerical example of profit allocation mechanism among Yonghui Supermarket and cooperative enterprises, and verifies the effectiveness of the models and methods.The results given in this paper alleviate the bottlenecks of agricultural products circulation effectively, and provide an important theoretical basis as well as some technical supports for the study of agricultural products supply chain management under the “Agriculture-supermarket Jointing” mode in my country.
