拥有互补性专利的双寡头厂商可以进行三种方式的专利交易,分别是无专利授权、交叉许可授权和专利联盟授权.通过构建两阶段动态博弈模型计算不同专利交易方式的市场绩效,并从企业和社会两个角度分析三种专利交易方式的优劣.结果表明:从企业层面来说,专利联盟授权是企业最优的专利交易方式,因为专利联盟授权使企业获得最大的生产者剩余;而从社会层面来说,政府应该认真审核积极引导专利联盟的组建,因为专利联盟授权有可能降低消费者剩余,损害消费者利益.

This paper computes the market performance of three types of patent transaction by building a two-stage dynamic game model, and analyzes the merits and demerits of three types of patent transaction standing the point of the company and the society. In conclusion, patent pools licensing is the most effective type of patent transaction from the company's perspective, because the patent pools licensing makes the most producer surplus; The government should testify and pilot the construction of patent pools from the perspective of the society, because the patent pools may impair the benefit of consumer by reducing the consumer surplus.
