Information asymmetry leads to short-term competitive antagonism between downstream manufacturers and upstream suppliers. This paper applies a master-slave game to reproduce the interest conflict between a manufacturer and a supplier, and proposes a cooperative decision-making model based on information sharing, considering the interest consistency of upstream supply chain members. Additionally, the overall profit coordination mechanism is constructed to ensure the continuation of the cooperative decision-making relationship. In addition, to ensure that the supplier participating in cooperative decision-making has the supply capacity desired by the manufacturer, a rational evaluation system combined with game theory is employed to determine the most suitable participating supplier. A numerical example is given to demonstrate the systematization and effectiveness of the proposed method. Finally, through sensitivity analysis and comparative analysis, managerial insights and recommendations are obtained.

信息不对称导致下游制造商和上游供应商之间的短期竞争对抗。本文运用主从博弈重现了制造商与供应商之间的利益冲突，并在考虑上游供应链成员利益一致性的基础上，提出了一种基于信息共享的合作决策模型。此外，构建了整体利润协调机制，以确保合作决策关系的延续。另外，为了确保参与合作决策的供应商具有制造商期望的供应能力，采用合理的评估系统和博弈论相结合来确定最合适的参与供应商。数值算例表明了该方法的系统性和有效性。最后，通过敏感性分析和比较分析，可以获得管理方面的见解和建议。
