Different from the academic groups of the “scholars in the same discipline” in higher education disciplines, the academic groups of the “scholars in the same research field” oriented towards specific research directions not only have a wide range of social practice foundation, but also have distinct scientific sociological research value. The research academic community in the field of “Double First-Class” construction has begun to take shape. In view of its “urban” research characteristics, a large group of core scholars has been formed. There is an obvious “long tail phenomenon” in the distribution of publications of this group with serious differentiation of citation frequency and obvious typification of co-authored papers. The internal structure of academic groups has a low degree of aggregation, the phenomenon of group separation is obvious, and there is a significant small-world effect. There is still a strong potential for interconnection and interaction among all groups. Scholars in the center of the network have important information and social capital in the research field of “Double First-Class” construction, so they have strong academic leadership and social recognition and the most extensive communication and cooperation ability. There is a strong correlation between the knowledge network and the social network presented by the typical subnets of academic groups. The social capital of the core scholars in the subnets has great influence on the knowledge production process of team members.
