Abstract: Public research institutes are one of the important actors in national innovation system. Identifying the role of public scientific research institutes in the national innovation system could promote the comparative research and evolution analysis of public research institutions. Based on typological analysis logic, a role classification model of public research institutes is established from two dimensions of social network analysis: network size and mediating role, and an empirical analysis is carried out with the research institutes of Chinese Academy of Sciences. The study found the role types of the research institutes of Chinese Academy of Sciences, and the field characteristics behind the role differences.
