Analysis Of New Agricultural Order Supply Chain Optimization Model Based On Option Contract

Nowadays,coordination of agricultural products supply chain is a hot research topic during scholars.Affected by the factors of farmers and the purchasing companies themselves,and the imperfect contract leads to the lack of effective and reasonable profit distribution mechanism among the participants,which leads to a high default rate and frequent defaults in the supply chain of agricultural products.In this case,based on the "peasant household + cooperative + enterprise" model of order agricultural supply chain.The cooperative distributes a part of the income to the peasant household in proportion.The cooperative society provides a fixed fee according to the size of farmers' land area.Cooperatives also hire workers to grow crops,and farmers can choose to apply to be employees so they can get an extra paycheck.The supply chain model not only guarantees the basic benefits of farmers,but also reduces risks and improves participation.Meanwhile,the transaction between cooperatives and enterprises is relatively equal.Aimed at the default problem in order agriculture,the agricultural products supply chain is put forward through the option contract to coordinate the supply chain of agricultural products,at the same time in order to reduce the impact of the market price changes,companies in the options market to buy options for hedging,through B-S option pricing model to guard against the risks of market prices fluctuate frequently.The condition of using risk valuation(CVaR)metric cooperative profit under the premise,in this paper,by analyzing the decentralized decision making mode and centralized decision mode,purchase contract and option contract trading under the optimal decision of agricultural products,and through the control of signing contracts accounted for the proportion of the total output of agricultural products to motivate cooperatives from the perspective of the supply chain benefit maximization to select the optimal agricultural output,So as to achieve supply chain coordination.Then two supply chain incentive models are discussed to compare the supply chain earnings changes before and after the purchase of options in the options market.Finally,a case study is made to verify and compare the decision-making behaviors of cooperatives and enterprises under purchase contract and option contract.
