This article models social networks, explains in detail two common propagation models, and gives the definition of the problem of maximizing influence in social networks. On the basis of which, the maximization of influence is introduced into the scientific collaboration network. It's mainly used to describe the cooperative contribution between scientific research scholars, the scientific research innovation ability and the academic leadership ability of the cooperative team.
