摘　　要：讨论了生产同质商品的寡头对市场价格有不同程度影响时的产量稳定性分析.在离散时间模型中,对一般的非线性价格函数,得到不稳定的条件,在线性情形下,将看到全局稳定的充要条件是厂商数目不能超过3.This paper focuses on the stability when the oligopolists have different power of affecting market price due to their market strategies even though their products are homogeneous.In discrete time model,conditions are unstable,I also examine the conditions under discrete time process,and it is interesting to see that to ensure global stability,when the inverse demand function is linear,the number of the firms in the industry should be no more than 3.

关 键 词：古诺调整过程 局部渐进稳定 全局渐进稳定
