耐用品市场企业租售策略研究

在耐用品垄断厂商同时生产耐用产品和易耗部件的前提下,建立了耐用品和易耗部件的有关耐用度的两期需求-价格模型.通过模型可以发现存在租赁的耐用品生产者将会在成本最小化的基础上生产社会效用较高的耐用品,而为了追求更多的利润他们会只考虑降低易耗部件的使用寿命,从而验证了Swan的市场独立化的结论时于生产易耗部件的耐用品租赁者是成立的.然而,对于耐用品的销售市场,Swan的市场独立化结论不再成立.耐用品垄断企业会采取计划废弃的策略,在不同程度上生产耐屯用度较低的耐用品及其易耗部件.在易耗部件使用寿命相对很高时,耐用品垄断企业会最大化其计划废弃策略.

Study on Leasing-selling Strategy for Durable Goods Market

When the durable goods and easy-to-wear accessories （EWAs） of the durable product are offered by the same monopolists , a two- period Demand-Pricing model concerning the durability of the durable goods and EWAs is built up. According the model, the social efficient cost-minimizing durability of durable goods independent of the durability of EWAs will be gotten by renting firms. And the durability of EWAs will be considered by the manufacture who pursues the more profit. Thus Swan＇s market independence result can be extended to durable goods renters that manufacture EWAs of the durable products. However,the result is not suitable for sales markets. With sales,plarmed obsolescence both of durable goods and EWAs will be practiced by monopolists. And goods and EWAs with uneconomically short lives will be manufactured in different degrees. It＇s found that planned obsolescence of durable products is maximized when the easy wear accessories are highly durable.
