文章研究垂直市场结构,其中上游要素市场为垄断市场,下游为古诺寡头市场,下游企业同时需要选择它们的内部渠道结构。利用古诺数量博弈模型,采用逆向法求解子博弈完美纳什均衡,得到两个主要结论:第一,垄断要素供给者采用单一定价比采用差别定价获得的总福利要高;第二,对垄断要素供给者来说,采用单一定价比差别定价获利更多。
The article studies the vertical market structure, in which the upstream factor market is the monopoly market and the downstream is the Cournot oligopoly market. The downstream enterprises also need to choose their internal channel structure. Using the Cournot quantity game model and the inverse method to solve the perfect Nash equilibrium in the subgame, we get two main conclusions: First, monopoly factor suppliers adopt a single pricing method to obtain higher total welfare than differential pricing; secondly, monopoly factors Providers, using a single pricing differential pricing more profitable.
