基于Samiran Banerjee和Ping Lin的纵向合作创新模型,通过引入上游企业间双寡头竞争关系和创新成本函数,探讨在产业链上游双寡头竞争条件下,当以过程创新为目的上游创新企业的研发成本分担比例一定时,上游创新企业与下游成员企业的联盟策略,及其对四类企业利润函数的影响.研究表明:上游创新企业的合作创新活动不仅可以提高合作创新联盟企业的利润,而且下游非成员企业也会从中受益,从而使行业总利润得到提升.
Based on the vertical cooperative innovation model of Samiran Banerjee and Ping Lin, this paper explores the R & D cost sharing of upstream innovative enterprises for process innovation under the conditions of duopoly competition in the upstream of the industry chain by introducing duopoly competition and innovation cost function among the upstream firms. The proportion of upstream innovation enterprises and downstream member firms, and their impact on the profit functions of the four types of firms.The research shows that the cooperative innovation activities of upstream innovation firms can not only increase the profits of cooperative innovation alliance firms, but also the downstream non-members Enterprises will also benefit from, so that the overall industry profits have been enhanced.
