摘 要: 研究了一个Cournot竞争的演化博弈模型。企业在两种行为规则中进行选择,一种是"近视眼"行为规则,另一种是纳什行为规则,行为规则被选择的概率由复制者动态方程给出。结论表明:复杂的纳什行为规则不可能淘汰简单的"近视眼"行为规则,并且,在满足一定的条件下,企业都将选择"近视眼"行为规则来进行产量决策,而能否获得均衡产量则取决于企业的理性程度。 An evolutionary game model of Cournot competition is studied.Two behavior rules can be selected by enterprise.One is'myopic'behavior rule,the other is Nash behavior rule.The probability of the enterprise choosing a certain behavioral rule is updated according to the replicator equation.Our results show that'myopic'behavior rule cannot be washed out by Nash behavior rule,and enterprise will select'myopic'behavior rule to make quantitative decision when it has certain rationality,and its rationality determines whether this game can reach equilibrium.
