Abstract: OEM is an important manner of international economy cooperation.The Stackelberg game decision model of the OEM operation is established，based on the relationship of the consignors and the accepters.In this paper，firstly the respective decision behaviors of the consignors and the accepters are discussed.Then a Stackelberg game decision model of the OEM operation is set up.Finally a polynomial-time algorithm for the optimal strategy of OEM is gotten by using dual theory of bilevel programming.

Key words: OEM, Stackelberg game, bilevel programming, polynomial-time algorithm

摘要： 随着经济全球化的发展和经济的区域化分工，OEM合作已成为一种重要的企业间生产方式。通过分析OEM业务中委托方和被委托方的决策行为及双方关系，建立OEM业务的Stackelberg博弈策略模型，并研究求解算法。首先，分析OEM业务中的委托方和被委托方各自的决策行为；进而以此为基础，建立OEM业务的Stackelberg博弈策略模型。最后，利用双层规划的对偶理论，给出求解OEM业务最优策略的一种多项式时间算法。
