The distribution proportion of decentralized and centralized supply chains indicates the maturity of supply chain development. As it is well-known, decentralized and centralized decision-making modes are common in the supply chain game. Decision makers often adjust their decision-making process to the development for themselves day by day according to the changing market. In this paper, a study is conduc-ted for a two-level supply chains composed of manufacturers and retailers. A payoff matrix in the game be-tween the manufacturers and the retailers are constructed. With relevant parameters and numerical exam-ples, evolutionary stable strategies are analyzed by using a Jacobi matrix. The effects of the parameter changes on the evolutionary direction between decentralized and centralized supply chains are discussed in detail. Results show that decision-making results are significantly influenced by parameters such as profits and costs in the supply chains.%探讨了由生产商与零售商组成的两级供应链,分析链上成员之间的博弈从而构建两者的支付矩阵,通过计算雅可比矩阵,掌握供应链的演化稳定策略.通过参数分析与数值算例,详细讨论了参数变化对分散式与集中式供应链演化方向的影响,结果显示,供应链中决策受收益、成本等参数的影响显著.
