摘要: 运用过程创新基准效益的概念和异质产品寡占模型的分析方法,将双寡头古诺模型扩展到同类异质产品竞争的三方寡占的古诺模型.研究了过程创新的博弈过程,得到满足私人效益最优的投资水平与满足社会效益最优的投资水平并指明了求解过程.两种最优化过程具有密切联系.将模仿创新者的模仿吸收能力识别为除技术领先者和模仿者之间的技术势差外又一影响模仿创新的因素.探讨了纯技术溢出并在修正原有学习模型的基础上建立了基于学习动力和学习能力双因素的学习模型.建立过程创新的古诺模型和学习模型都将把原有模型拓展到更符合大多数产业竞争和制造与创新过程的现实情况.

Abstract: The concept on benchmark benefit of process innovation and the method of analyzing on oligopoly competition model with heterogeneous products were applied to extend the original study of two participants to the case of three participants in Cournot oligopoly. The gaming process of innovation was researched. Both the innovation level maximizing private profit and that maximizing social profit were brought out and the solving process was given. The main characteristics of the two optimizing process have undeniable connections. The innovation follower-s absorbing capacity was recognized as another factor influencing the imitated innovation, besides the knowledge distance between the innovation leader and its follower. The pure knowledge spillover was studied and absorbing capability was brought to help found another study model based on both study force and study capacity. Both the process innovation-s Cournot model and the innovation-s study model can extend the original models to real competition in most industries and manufacturing & innovation reality.
