| 摘 要： | 假定两家厂商生产的同种产品具有质量差异,及消费者对产品质量偏好服从d,e]区间上的均匀分布情况,研究了二次运输成本Hotelling模型:两家厂商首先沿0,1]线性城市同时选址,然后进行价格竞争.运用后退归纳法得到了子博弈精炼Nash均衡,此时厂商将选址于城市中心。

| Abstract: | Under the assumption that two firms produce same kind of product with different quality and consumers' preference for product quality is uniform distribution on,Hotelling model with quadratic transportation cost functions is studied.The firms simultaneously choose their location along linear city,then compete in price.The subgame perfect Nash equilibrium of two-stage dynamic game is obtained by backward induction method.The conclusion is that the firms will both locate themselves at center. |
