寡头竞争的拓展模型分析

Studies on Spreading Models of Oligarch Competition

在传统的Cournot及Stackelberg寡头竞争模型的基础上提出了其相应的拓展模型,分析了当寡头数≥2时,企业的利润情况;并就两种模型下的结果进行了比较与分析,得出在Stackelberg竞争模型下,后动企业利润不一定小于Cournot模型下的利润的结论.该结论修正了目前的一些观点.

On the basis of traditional oligarch competition of Cournot and Stackelberg, we put forward their corresponding spreading models, analyze the profits, which the enterprises gain, if n≥2; compare and analyze the results under the twomodels. Finally, we get the result that the profit of following enterprises in Strackelberg model is not truly less than that in Cournot model. And the result modifies some views at present. 
