摘　　要：主要从追溯层级方面来探讨供应链追溯系统的构建,基于零售商主导情形下的一个供应商和两个竞争性零售商的两阶段供应链,分析了零售商的最优追溯策略选择。发现当零售商追溯投资系数较小时,实现完美的追溯层级努力,但随着追溯投资系数的增加,超过一定阈值时,零售商追溯层级的增加受到追溯成本增长的制约反而会带来自身利润的下降,因此存在着一个最优的追溯层级设置,在该点上实现自身利润的最大化。此时的最优追溯层级主要受到市场竞争系数、追溯差异竞争强度系数、召回成本等外部市场环境因素的影响,市场竞争系数增加将会降低最优追溯层级,追溯差异竞争强度系数和召回成本的增加将有利于最优追溯层级的增加。In this paper,we looked at the construction of the supply chain traceability system mainly from the angle of tracing hierarchy.More specifically,based on a two-echelon supply chain composed of one supplier and two dominating but mutually competitive retailers,we analyzed the optimal tracing strategy option for the retailers.Through the analysis,it was found that when the retailers'tracing input coefficient is small,an ideal level of tracing hierarchy effort could be achieved;however,as the coefficient increases past a certain threshold,the increase of the retailers'tracing hierarchy,as it is restricted by the growth of the tracing cost,would drag down their own profits.Consequently,there is an optimal tracing hierarchy setting at which their own profits could be maximized.Said optimal tracing hierarchy is mainly affected by market competition coefficient,tracing difference competition intensity coefficient,and recall cost,etc.,where an increase in market competition coefficient would reduce the optimal tracing hierarchy,while an increase in tracing difference competition intensity coefficient and recall cost would help increase the optimal tracing hierarchy.
