耐用品问题引起众多学者的关注，而对易耗部件兼容情况下的耐用品耐用度和易耗部件更换次数对耐用品租赁厂商决策的影响问题，采用两阶段数学决策模型进行研究，发现：耐用品垄断厂商第二阶段的耐用品最优产量与耐用品的耐用度之间负相关；第一阶段的耐用品最优产量与耐用品耐用度之间随耐用品耐用度的增加呈先负相关后正相关的趋势；耐用品垄断厂商和独立的易耗部件供应商在两个阶段内的易耗部件最优价格都分别与各自的易耗部件更换次数正相关。

Many scholars have focused on the problem of durable goods. In Easy-to-wear Accessories （EWAS） compatible cases, a two-stage mathematical model is used to study how the durable goods leasing monopolist＇s decision is impacted by the durability of durable goods and the replacement number of EWAS. The results show that the monopolists＇ optimal output of durable goods at the second stage has negative correlation with the durability of durable goods. At the first stage, the optimal output of durable goods first decrease and then increase with the increment of the durability of durable goods. The optimal prices of EWAS, in two stages, of both the durable goods monopolist and the independent EWAS supplier, have positive correlation with their own replacement number of EWAS respectively.
