摘　　要：应用两阶段博弈模型分析了企业的产品成本随企业厂址不同而变化时混合寡头的选址决策问题,扩展了以社会福利最大化为目标的国有公有制企业和以利润最大化为目标的私营企业之间竞争的区位-产量选择模型。结果表明,国营企业与私营企业不会形成集聚,它们将分散在市场中。进一步,得到了混合寡头分布在圆环直径两端时,产品成本分布函数必须满足的条件。The location choice of a mixed oligopoly is analyzed by using a two stage game when production cost is different across locations and the location-quantity choice model of a mixed oligopoly,where a state-owned welfaremaximizing public firm competes against a profit-maximizing private firm,is developed.The results show that public firm and private firm can never agglomerate in the same area,and they will locate in different areas.Furthermore, when the mixed oligopoly locates equidistant from each other,the conditions that the product cost distribution function must satisfy are obtained.
