Research On Quality-Safety Of Agricultural Supply Chain From The View Of Evolutionary Game

With the improvement of people’s living standard and the quality of life, safety requirements for agricultural products have also been greatly improved. In recent years,quality-safety problems of agricultural products in China are increased, quality-safety issues of agricultural products become an obstacle factor to our nation’s economic development and people’s quality of life level, at the same time, this issue has a certain negative impact on the society. A heightened awareness of the quality-safety of agricultural products, as well as market competition of agricultural products promotes organization forms of agricultural products supply chain to close and integrate increasingly. The interests of all parties in the supply chain of agricultural products are complex, not only endogenous interest-driven, but also accompanied by continuous changes of external constraint condition. Game interests imbalance among the parties in the supply chain of agricultural is the crux for the quality-safety accidents of agricultural products, and at the same time it leads to the lack of social trust. With strengthen of agricultural products supply chain integration, cooperation between game bodies is particularly important to improve the quality-safety of agricultural products supply chain. Therefore, exploring delicate interests for supply chain of agricultural product between the game participators, studying the mechanism of evolutionary game theory,these have significance to construct perfect system of quality-safety of agricultural products supply chain.This article is based on evolutionary game theory and transaction costs theory and so on,discussing the situation and obstacle factors of the quality-safety of agricultural products supply chain, establishing model of evolutionary game. At the same time, the cooperation relationship between the town of Lianshan in Pulandian as an example, discussing evolutionary game relationship among upstream and downstream stakeholders of agricultural products supply chain. We obtain data from the survey of Lianshan town in Pulandian, large chain supermarkets and consumers, finding public factor that affects quality-safety of agricultural supply chain through applying SPSS software factor analysis, then analyzing evolution path between game participators by Evolution Game Model. At last, gettingevolution stable strategy, and putting forward rational recommends which is beneficial to the quality-safety of agricultural products supply chain.
