中文摘要：

利用Stackelberg博弈理论考察了具有直接销售渠道和间接销售渠道的闭环供应链的定价以及制造商回收渠道的选择等问题，构建了3种不同回收渠道下的闭环供应链模型。研究发现：①当间接销售渠道销售产品的市场份额在不同范围内取值时，批发价格和直接销售渠道的销售价格呈现出不同的关系；②当3种回收渠道的回收成本相同时，制造商回收渠道的效率更高；③影响回收渠道选择的主要因素与制造商所获利润的大小有关，当3种回收渠道的回收成本相同与不同时，制造商会根据自己所获利润的大小，选取不同的回收渠道对废旧品进行回收。

英文摘要：

This paper studies the pricing of the closed-loop supply chain with direct and indirect distribution channel and the selection of collecting channel by Stackelberg game theory. Closed-loop supply chain models under three different collecting channels are constructed. The results show. ① The wholesale price and the selling price in direct distribution channel exhibit different relationships, when the choice of the number in certain range with market share of indirect distribution channel;② The efficiency of the manufacturer＇s collecting channel is higher when the collecting cost are the same in three collecting channels; ③The main factor that influence the selection of the collecting channel is relevant to the manufacturer＇s profit. According to the condition of the collecting cost under three collecting channels, the manufacturer selects different collecting channel deciding on its profit.
