Abstract: In view of the uncertainty of agricultural produce market in the future, an agricultural supply chain coordination model with option contract was constructed. The optimal decision-making behavior of the members of the agricultural supply chain was researched under the conditional value at risk (CVaR) method and the influence of option contract on decision-making of produce and order was analyzed under the different farmer's risk averse degree. The results show that the farmer's output quantity is a decreased function and enterprise's return is an increased function. The "enterprise + farmer" contract-farming supply chain's performance can achieve pareto improvements after introducing the option contract.
