This paper proposes a propensity index based on the propensity of individuals to disseminate public opinion information, and investigates the influence of the propensity index on the process of information dissemination and the density of infection in the network. The results show that the propensity index affects the process of information dissemination and the change of infection density, the higher the propensity index of an individual, the faster the information dissemination in the network, and the information dissemination method with a dynamic propensity index is more in line with the information dissemination law in reality.
