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.
Keywords�� Cournot model   oligopoly   process innovation
