存在成本差异的双寡头企业选址定价博弈

针对传统的Hotelling线段模型中假设双寡头企业的生产成本完全相同这一问题,应用两阶段博弈模型,提出了双寡头企业成本存在差异条件下的企业选址定价模型·结果表明:当双寡头企业同一质量的产品实现最大差异化时,虽然两企业都能获得利润,但具有成本优势的企业却能获得比成本劣势企业更多的超额利润;当双寡头企业同一质量的产品实现最小差异化时,具有成本优势的企业将占据市场,具有成本劣势的企业将远离成本优势的企业或退出市场·

Locating-Pricing Game of Duopoly Enterprises at Different Costs

Aiming at the problem that the traditional Hotelling segmentation model was assumed that the production costs of duopoly enterprises are completely the same, with the two-phase gaming model applied to it. A locating-pricing model is proposed for both enterprises at different costs. The results show that when the difference the products of the same quality supplied by the duopoly enterprises is maximized, the enterprise which is superior in cost to the other one will gain more excess profit though both can gain profit. However, when the difference is minimized, the enterprise superior in cost will be dominant on market and the inferior one has to fall far behind the former even retreat from the market.
