耐用品及其易耗部件耐用度对双寡头企业均衡产量的影响研究

Impact Study of Duopoly Firms' Equilibrium Yields from Durability of Durable Goods and Easy-to-Wear Accessories

为了研究耐用品双寡头企业的竞争策略,基于Bulow的耐用度选择模型,建立了存在易耗部件情况下的双寡头耐用品企业两期需求一价格模型;求得了双寡头耐用品企业租赁情况下的两期均衡产量;并运用MATLAB软件对均衡解进行仿真,分析了双寡头耐用品企业自身和对手的耐用品耐用度及易耗部件耐用度对均衡产量影响。

In order to research competitive strategy on durable goods duopoly finns with easy-to-wear accessories （EWA）, based on Bulow＇s durability choice model, a two period model concerning durable goods duopoly finns with EWAs is set up. The duopoly durable goods rental finns＇ equilibrium yields solutions are got. A two-dimensional simulation is given by MATLAB for equilibrium solutions. The affect of both the durable goods durability and EWAs durability from themselves or their competitors on the equilibrium yields is analysed.
