摘　　要：中间层理论考察了企业的购买与销售策略的关系,解决了Bertrand悖论问题,为传统的产业组织模型增添了新的视角.本文以Stahl(1988)为基础,将斯普尔伯(2002)对称的双寡头垄断中间化对称模型进行扩展,分析了投入品与产出品都不同的非对称寡头竞争模型,并详细考察了供给、需求差异化参数对竞争的影响.该模型较完整地描述了市场运行机制和竞争战略,得到了与传统的产业组织方法非常不同的结论.The theory of intermediaries has investigated the relationship between buying and selling strategies, and solved the Bertrand paradox, providing a new perspective for traditional model of industry organization. Based on Stahl（1988）, this paper extends symmetric model in duopoly in Spulber（2002）, analyzes the asymmetric model of competition with both different inputs and outputs, and examines in detail the impact of differential parameter of supply and demand on competition. The model characterizes the features of market mechanism and competition strategies, which draws a different conclusion from traditional approach of industry organization.
