销售渠道选择和再制造质量投入是影响再造品销售的关键因素, 企 业的利他关切行为是维持供应链结构稳定性的重要保障. 分别基于单、双销售 渠道结构, 构建了制造商有、无利他关切的4种闭环供应链模型, 首先对比 了不同渠道结构下产品定价, 需求量以及成员利润的差异, 其次, 进一步分 析了不同渠道结构中利他关切行为和质量投入产生的影响. 研究结果表明: 1)一般而言, 双渠道模式中产品的销售定价较低, 再造品以及整体需求量均更高, 而当制造商完全利他时, 两种模式下产品的销售定价、需求量以及闭环供应链的整体利润均一致. 2)单渠道模式中制造商的利他关切行为可以促进产品整体销量的提升, 双渠道模式中则会导致部分再造品消费者流入新产品市场. 3)再制造质量投入始终能够提升消费者认可度, 壮大再造品的销售规模, 双渠道模式更利于制造商开展质量投入活动.

Sales channel selection and remanufacturing quality investment are the key factors affecting the sales of remanufactured products, and altruistic concern behavior of enterprises is an important guarantee to maintain the stability of supply chain structure. Based on the single and double sales channel structures, four closed-loop supply chain models with and without altruistic concerns are constructed. Firstly, the differences of product pricing, demand and member profits under different channel structures are compared. Secondly, the influences of altruistic concerns and quality input in different channel structures are further analyzed. The results show that: 1) Generally speaking, in the dual-channel mode, the sales pricing of products is lower, while the demand of remanufactured products and the overall demand are higher. However, when the manufacturer is completely altruistic, the sales pricing, demand and the overall profit of the closed-loop supply chain under the two modes are consistent. 2) In the single-channel mode, manufacturers' altruistic concern behavior can promote the overall sales of products, while in the dual-channel mode, some remanufactured consumers will flow into the new product market. 3) Remanufacturing quality investment can always improve consumers' recognition and sales of remanufactured products, and the dual-channel model is more conducive to manufacturers' quality investment activities
