The invention belongs to the field of social network analysis, and discloses an information situation awareness and propagation management and control model based on node influence. The model comprises a data acquisition module, a characteristic extraction module and an information situation awareness and propagation module, wherein the data acquisition module obtains source data from a social network, obtains the personal attribute, the historical behavior and the friend relationship of a node from the source data, and constructs an information propagation network; the characteristic extraction module independently extracts characteristics from two dimensions including a network dynamic attribute and an interaction dynamic attribute, and independently calculates corresponding factor functions; and the information situation awareness and propagation module constructs the information situation awareness and propagation management and control model on the basis of a mean-field theory, simulates an information propagation tendency, perceives an information diffusion tendency, captures the peak hour of information outburst, and mines a dynamic factor which drives the information to be propagated. By use of the method, the dynamics reason of the information propagation in an on-line social network can be effectively explained, an information propagation evolution situation in the social network is perceived, and the method can be widely applied to the relevant field of information propagation.
