Abstract:As a service decision-making agency of science and technology think tank, its research is highly comprehensive. It hopes to expand the theoretical dimension of knowledge research in science and technology think tanks, and combine the analysis of the talent network to improve the theoretical practice, so as to enrich the knowledge and theoretical exploration of the construction of science and technology think tanks.From the perspective of knowledge research, the relationship between the knowledge innovation of science and technology think tanks and the construction of talent networks was discussed. Then the social network analysis was used to analyze the mechanism of action of the talent network on the knowledge innovation of science and technology think tanks, taking the Institute for Future Engineering as an example. It is found that the talent network of Japanese science and technology think tanks has the characteristics of core, diversification and interactivity, which has led to the enlightenment of further improving the talent training and knowledge innovation capabilities of science and technology think tanks.
