本文针对单个制造商和零售商组成的闭环供应链系统，基于博弈论的基本方法，分别构建了集中式、制造商领导的Stackelberg博弈、零售商领导的Stackelberg博弈、制造商和零售商存在Nash均衡博弈等模式下的闭环供应链决策模型，进而对比分析消费者搭便车行为对不同权力结构闭环供应链的决策及利润等影响问题。研究表明，集中式决策闭环供应链的总利润和分散式决策中各权力主体的利润受到搭便车系数的影响；各权力结构下网络直销渠道的销售价格和市场需求均随搭便车系数的增加而增加等。

This article, which depends on the breakthrough point of Consumer Free Riding Behavior aiming at the closed-loop supply chain system composed of the single manufacturers and retailers, studies how Consumer Free Riding Behavior affects the policy, channel and profit of the different authority structure of closed-loop supply chain (CLSC) based on the game theory by constructing the decision-making models of centralized decision, manufacture-Stackelberg game, retailer-Stackelberg game and manufacture-retailer Nash Equilibrium respectively. The research shows that the total profit of the centralized decision-making closed-loop supply chain and the profit of authorities under the decentralized decision-making of the Stackelberg game leading by manufacturer are influenced by the free-riding coefficient. The price of direct channel and market requirement increases with the increase of free riding coefficient in all condition.
