生产商、批发商和销售商信息合作行为的演化博弈

针对低碳农产品供应链信息共享机制不完全与合作商之间存在博弈的现象,提出生产商、批发商和销售商信息合作演化路径,为了探究供应商信息合作的因素和利益关系,构建 3 种信息合作演化博弈模 型;首先,求解出生产商与批发商合作模型和批发商与销售商合作模型以及 3 方信息合作模型下的演化博弈 均衡解,通过对模型稳定性的分析,得到在供应链成员行为决策和期望利润驱使下系统整体随时间变化的动 态趋势;然后,将不同信息合作下的决策行为进行仿真分析,并对比3种模型,探索得出均衡策略和影响因素 的作用原理;最后研究结论表明:选择合作收益大于非合作情况下的收益,并且演化博弈系统最终趋向于合 作博弈策略,使总体和个体达到收益最大化。

Evolutionary Game of Information Cooperation Behavior of Manufacturers, Wholesalers and Sellers

In view of the phenomenon that the information sharing mechanism of low-carbon agricultural supply chain is not complete and there is a game among cooperative partners, the evolutionary path of the information cooperation between producers, wholesalers and sellers is proposed. In order to explore the factors and interests of supplier information cooperation, three evolutionary game models of information cooperation are constructed. Firstly, the equilibrium solution of the evolutionary game of the manufacturer-wholesaler cooperation model, wholesaler-seller cooperation model, and tripartite information cooperation model is obtained. Through the analysis of model stability, the dynamic trend of the system as a whole changing with time driven by the behavioral decisions and expected profits of supply chain members is obtained. Then, the decision-making behavior under different information cooperation is simulated and analyzed, and the equilibrium strategy and the principle of influencing factors are explored by comparing the three models. Finally, the results show that the benefits of cooperation are greater than those of non-cooperation, and the evolutionary game system eventually tends to be a cooperative game strategy to maximize the overall and individual benefits.
