Reduction Strategies Of Food Supply Chain Under Different Cooperation Modes

Throughout history,food security has been a top priority in the governance of the country,and ensuring food security has become an important part of the modernization of the national governance system and capacity.As the saying goes,food is the first thing that people eat,and food is the first thing that they eat.Food security is not only about ensuring that people are well fed,but also about ensuring that they eat with confidence;in a way,it is about ensuring the quantity and quality of food,so that food security is truly in our hands.Reducing food losses is an important way to ensure food security,not only in terms of quantity,but also in terms of quality.In recent years,the state has introduced many policies to reduce food losses,promote the whole chain of food loss reduction,and promote the cooperation between the upstream and downstream of the food supply chain,but the cooperation between the various links still needs to be strengthened.In this paper,we select the grain storage and processing links in the grain supply chain for research,and use Stackelberg game theory to study the optimal cooperation mode for loss reduction under three different cooperation modes,and verify this model with cases,in order to provide ideas and theoretical basis for loss reductionThe research in this paper consists of four major parts.(1)Definition of concepts and theoretical basis:Firstly,the concepts of food loss reduction,food supply chain,food supply chain loss reduction and food supply chain cooperation model are defined;then the models used in food supply chain structure and food supply chain cooperation are explained to provide the theoretical basis for the subsequent model construction.(2)Analysis of the current situation:Through semi-open-ended interviews and field research,the current situation of grain supply chain loss reduction is explained,and the problems of grain loss reduction in different modes of cooperation in the grain storage and processing sectors,which are the subject of this study,are analyzed to provide a realistic basis for the establishment of three models of grain supply chain loss reduction strategies in different modes of cooperation.(3)Model construction and solution:Based on the theoretical basis and the current situation,a model of grain supply chain loss reduction strategy under three different modes of cooperation,namely complete non-cooperation,semi-cooperation and complete non-cooperation,is constructed,and the key factors affecting the choice of loss reduction strategy are analyzed with the level of grain loss reduction effort as the decision variable,and the level of loss reduction effort and profit of the three modes of cooperation are compared Finally,the validity of the model was verified by numerical simulation using Matlab software.(4)Case study:Enterprise X was selected as a case study to verify the feasibility of the model in practical application.Through the above research,the following conclusions are drawn from this article.(1)The highest level of loss reduction and supply chain profits for grain storage and processing enterprises under the full model In all three modes of cooperation,both grain storage and processing companies have the highest levels of impairment and supply chain profitability in the fully cooperative mode of impairment and price cooperation,so companies should strengthen their cooperation with each other in order to face consumer demand together when impairing.This is because with semi-cooperation and full non-cooperation,supply chain members make decisions alone or partially cooperatively,and make decisions with their own interests in mind,thus reducing the level of impairment effort and consequently profits The results of the study show that cooperation between enterprises is conducive to food saving and loss reduction,and that cooperation between each link should be strengthened in the future to improve quality and efficiency for food saving and loss reduction and contribute to China’s food security(2)The sensitivity coefficient of downstream to the level of loss reduction by grain storage and processing enterprises is positively proportional to the level of loss reduction efforts invested by storage and processing enterprises and the overall profit of the supply chain When buyers prefer higher quality products,they prefer companies with greater impairment efforts,then processing companies will expand their impairment efforts to maintain and expand market demand,and reserve companies will also increase their own impairment efforts to meet market demand in order to guarantee the quality of grain,and likewise to protect their own interests grain reserve and processing companies will also increase their respective selling prices,then the corresponding The overall profitability of the supply chain will also increase(3)The impairment cost coefficient of grain storage and processing enterprises is inversely proportional to the impairment efforts of grain storage and processing enterprises and the profitability of the supply chain.As the cost coefficient increases and decreases,the level of supply chain members’ impairment efforts also decreases,and market demand also decreases.At this time,the increase in profits brought about by the increase in demand can no longer compensate for the increase in costs,so it is unwise to invest in impairment efforts and expand market demand at this time,and the change in supply chain profits gradually flattens out as the cost coefficient increases,indicating that the cost coefficient is too large and the member enterprises put in The larger the cost factor,the lower the effort,and thus the smaller the impact on market demand,then the corresponding impact on supply chain profits will also become smaller.
