摘　　要：文章在非线性成本函数的假定条件下,对Cournot寡头竞争模型进行改进,建立了基于对数成本函数的Cournot模型。并与经典Cournot模型的均衡结果进行对比分析。结论表明,改进后的模型与现实问题的吻合度更好。This paper on the basis of the assumption of nonlinear cost function, ameliorates the Cournot oligopolistic competition model and establishes the Cournot model based on the logarithmic cost function. In the paper comparisons and analyses are made between ameliorated model and the equilibrium results of the classical Cournot model. The result shows that the improved model has better goodness of fit with the practical problems.

关 键 词：COURNOT模型 对数成本函数 均衡利润
