Research On The Decision-making Mechanism Of Agricultural Product Quality Input Based On Evolutionary Game Under The Mode Of "Agricultural Super Docking"

As a new development mode of modern agriculture in China,the rapid development of "farm super docking" is conducive to ensuring the stability of farmers’ income,avoiding the additional cost loss of agricultural products in the circulation process,and minimizing the influence of external factors on the circulation of agricultural products.By integrating all the resources in the supply chain,the cooperative relationship between all node enterprises in the supply chain of agricultural products tends to stabilize and promote the transformation of the supply chain of agricultural products into a value-added chain.However,with the rapid development of the "farm super docking" model,the quality and safety problems of agricultural products in the supply chain are becoming more and more prominent,and food safety incidents related to agricultural products occur frequently.And the main reason is that the "farm super docking" mode of rural cooperatives and supermarkets on the quality of agricultural products input level is uneven,and even some enterprises frequently take "free riding" and other unhelpful "farm super docking" continued behavior.Therefore,this paper aims to improve the stability of rural cooperatives and supermarkets in the supply chain of "farm super docking" in the input of agricultural products,to ensure the sustained high level of food safety construction development,the use of evolutionary game theory to carry out modeling research.First of all,this paper considers that under the anarchic control mechanism,only from the point of view of market demand to analyze cooperatives and supermarkets in the quality of agricultural products input decision-making choices,with the quality input of both sides will have a positive impact on market demand as the starting point to build a game model,and analyze the equilibrium of the evolution of both sides.Secondly,the introduction of government subsidy mechanism,analysis of the government under what kind of subsidies can make the evolutionary equilibrium of cooperatives and supermarkets to increase the quality of agricultural products input.Then,the evolutionary game model of how cooperatives with risk aversion consciousness under the supermarket inspection mechanism adopt quality input decision-making is constructed,and the evolutionary equilibrium of both sides under different initial conditions is analyzed.The results show that the cost of quality input by cooperatives,the additional benefits after adopting input strategy,the risk aversion coefficient of cooperatives,the inspection cost of supermarkets,the amount of fines and bonuses all have an impact on the stable equilibrium of both sides.In summary,this paper analyzes the decision-making choice of cooperatives and supermarkets in the quality input of agricultural products under the control of the government,and analyzes the decision-making choice of cooperatives in the quality input of agricultural products by establishing the supermarket inspection mechanism within the supply chain,analyzes the quality input of "farm super docking" agricultural products from the macro angle of the government and the micro-angle inside the supply chain,and then puts forward reasonable suggestions to improve the quality input level of agricultural products from many perspectives according to the conclusions reached.The development of supply chain plays a guiding role.
