中文摘要：
为了了解不同供应链协调合约决策主体的收益风险，采用产品市场与金融市场正相关的假设，对决策者的收益分析表明柔性合约（flexiblecontracts）和金融对冲（financialhedging）的避险功能存在一致性．在此基础上，以批发价格合约，回购合约为模型基础，考虑存在金融对冲的情况下供应链的优化问题．最后，以批发价格合约为例，零售商同时决策订购量和避险工具数量．模型的结果表明：对于风险规避者，金融避险工具的使用降低决策者风险导致批发价格合约的零售商提高订购量，这也间接证明了批发价格合约在实践中如此普遍的一个原因．
英文摘要：
In order to know of the revenue risk of the different agents in the supply chain, the hypothesis that product markets are positive correlation with financial markets was adopted. The analysis shows that flexible contracts are coherent with financial hedging instruments in hedging risk. Based on the results, modeled with wholesale price contracts and buyback contracts, the optimization of supply chain was solved using the financial hedging instruments. Finally the optimal decision on the order quantity and hedging quantity of the wholesale price contract was explained. The results of the model show that hedging instruments can decrease the profit risk, therefore risk-averse agents prefer to improve the ordering. It also proves indirectly that the wholesale price contracts are universal in supply chain contracts.
