我们研究了两家企业的区位选择，它们的目标是自己的利润和社会福利的加权平均值，在这两家企业在确定价格之前同时决定了它们的选址。本文的目的是考察不对称区位是否受到企业目标不对称或企业边际成本不对称的影响。我们证明，当两家公司具有相同的边际成本时，即使在不对称目标的情况下，均衡位置也总是对称的。另一方面，成本差异导致不对称位置处于均衡状态。也就是说，不对称的位置是成本不对称的结果，而不是企业目标不对称的结果。我们还证明了成本效率低下的企业对利润的追求可能会增加消费者剩余。
We investigate the location choice of two firms whose objectives are the weighted average of their own profit and social welfare, in which they simultaneously decide their locations before setting their prices. The purpose of this paper is to examine whether the asymmetric locations are influenced by the asymmetry of the firms’ objectives or by the asymmetry of firms’ marginal costs. We show that, when both firms have the same marginal cost, the equilibrium locations are always symmetric even in the case of the asymmetric objectives. On the other hand, the cost differences lead the asymmetric locations in equilibrium. That is, the asymmetric locations are a result of the cost asymmetry, but not the asymmetry of the firms’ objectives. We also demonstrate that the pursuit of profit by the cost-inefficient firm may increase consumer surplus.
