产品拆分再制造的市场结构演化分析

Market Structure Evolution of Product Split Remanufacturing

考虑了由一个制造商(M)和一个强势供应商(S)组成的二级再制造供应链系统。在产品可拆分再制造的情况下,对四种模型代表的市场结构进行了分析。最后通过数值算例,讨论了各成本以及再制造品的WTP变化时各市场结构之间的演化关系。结果表明:S再制造而M不进行再制造的市场结构不存在;当M再制造而S不进行再制造时,S的市场领导者的作用并未显现,各成本以及再制造整机的WTP变化会使此市场结构不稳定,M可通过给予S利润补偿的方式保证市场结构的稳定;当再制造品的WTP较低时,双方都实施再制造的(1,1)模型代表的市场结构并不稳定。

This paper considers two-level manufacturing supply chain system which consists of a manufacturer（M） and a strong supplier（S）.In the context of remanufacturing of product-dismantling,the market structures represented by four models are analyzed.Finally,the paper discusses the evolutionary relationships among the market structures when the four kinds of costs and the WTP of remanufactured goods change.Study results shows that the market structure of S-remanufacturing and M-no-remanufacturing does not exist,and in the case of M-remanufacturing and S-no-remanufacturing,the Superiority of S as the market leader does not appear.The change of costs and WTP of remanufacturing product will cause the market structure unstable,M can give S the profits compensation to ensure the stability of the market structure.Under the case of low WTP of remanufactured goods,the market structure which both parties implemented the remanufacturing can not be achieved.
