摘要： 在下游厂商采取产品创新条件下,利用Cournot数量竞争模型,比较研究了产业结构、技术溢出效应对上下游厂商合作创新决策的影响.研究表明,垄断性的上游市场结构更有利于下游厂商从事创新活动,竞争性的上游市场结构更有利于上游厂商从事创新活动.在垄断性产业结构下,上游产业利润和社会福利随着技术溢出效应的增大呈现出递减的趋势;在竞争性产业结构下,上游产业利润和社会福利随着技术溢出效应的增大呈现出先递增后递减的趋势,而下游产业利润不变.

Abstract: Utilizing the Cournot's quantity competition model, how the industrial structure and R&D spillover affect the cooperation between upstream and downstream companies for their innovation strategies were comparatively analysed. The results indicated that the upstream market monopolistic structure is beneficial to the downstream companies to innovate their R&D activities, while the competitive upstream one is beneficial to the upstream companies to do such activities. When the industrial structure is monopolistic, in the upstream companies the profits and social welfare for employees decrease with their increasing R&D spillover and, when the industrial structure is competitive in the upstream ones they increase first then decrease but the downstream ones remain their profits unchanged.
