Research On Supply Chain Coordination Mechanism Of Agricultural Product Security In China From The Perspective Of Evolutionary Game

The supply chain of agricultural products is the production and supply network of agricultural products.It is formed by production,processing,retail and other nodes,which have adverse factors on the safety of agricultural products,and they are connected with each other,sharing weal and woe.So far,to ensure the safety of agricultural products,it should not be limited to a single node or enterprise,but should be based on all nodes of the supply chain.The problem of agricultural product safety is caused by some distrust behaviors,such as unbalanced distribution of interests and asymmetric information among nodes in the chain.The emergence of these problems is closely related to the poor coordination of agricultural supply chain,and its solution also needs to establish a scientific and reasonable coordination mechanism to maintain the long-term stability of supply chain coordination.Based on the above analysis,aiming at ensuring the safety of agricultural products,this paper takes the representative three-level supply chain of "government supervision department + agricultural product enterprise + peasant household" in China's agricultural industrialization as the research object,comprehensively uses the evolutionary game theory,combines the quantitative and qualitative analysis methods,and discusses the trust mechanism,operation mechanism,benefit distribution mechanism and constraint mechanism respectively Supply chain coordination mechanism of agricultural product safety in China.The main contents of the study are as follows:First of all,through sorting out the relevant concepts and theories of the supply chain coordination mechanism of agricultural product safety,this paper puts forward the theoretical framework of the supply chain coordination mechanism of agricultural product safety.Secondly,in order to analyze the stability of the operation mechanism,from the perspective of trust among the members such as producers,processors,sellers and consumers,an evolutionary game model is constructed in the context of information asymmetry and information sharing.Third,in different market conditions,through the comparative analysis of four common methods of benefit distribution,the paper constructs the evolutionary game model of benefit distribution mechanism and constraint mechanism of "government supervision department + agricultural product enterprise + farmer" three-level supply chain coordination,and designs the realization of the constraint mechanism.Fourth,in order to promote the effective operation of the supply chain coordination mechanism of agricultural product safety in China,relevant policy suggestions are put forward.Finally,the main conclusions of this paper are summarized,pointing out the limitations of the research and the prospect of the research.
