摘　　要：针对仅一家企业拥有一种受专利保护的成本降低创新技术的异质产品Cournot寡头竞争市场,分析新技术拥有企业在固定费技术许可与按产量提成技术许可方式下的许可策略问题.证明对新技术拥有企业而言,在固定费技术许可方式下,当产品替代性程度不很大或者技术创新不很大时,专利技术拥有企业总将许可其非激变创新技术;且当产品替代性程度不太大时,新技术拥有企业也将选择许可其激变创新技术.在按产量提成技术许可方式下,新技术拥有企业将总选择许可其创新技术,且对于激变创新,若产品替代性程度不太大,则选择多家许可更优.In this paper, under fixed-fee licensing and royalty licensing, we analyze the licensing strategies of a patent-holding firm in a differentiated Coumot oligopolistic model with more than two firms and only the patent-holding firm having a cost-reducing innovation protected by a patent, respectively. It is illustrated that under fixed-fee licensing, the patent-holding firm is always willing to license its non-drastic innovation either when the products are not much substitutable or when degree of technology innovation is not great, and it is also willing to licensing its drastic innovation if the products are not close substitutes. Then, it is found that under royalty licensing, the patent-holding firm is always willing to license its innovation, and has the incentives to licensing its drastic innovation to multiple finns if the products are not close substitutes.
