Abstract: Trust is a bridge to connect complex social relationships among people. This paper will carry on it that is based on the network hierarchical mechanisms to research the relation of the dynamics transformation strategy of the level of individual trust and the dynamic spreading process of social network, and from the view of the independent spreading and interaction in two networks to study the influence of game on level of individual trust in the information dissemination process, improving the limitations of research of the single network. The nodes of the two layers conform to the rules of independent propagation in layers and interaction between layers. The propagation of nodes in the trust layer is treated by game evolutionary dynamics. The propagation of nodes in the information spreading layer conforms to the epidemic dynamics Susceptible-Infected-Recovered（SIR） propagation model, but it is affected by the trust factor of the trust layer. And the paper gives specific analysis of dynamic changes of each element on the Doubt-Trust-Mistrust-Susceptible-Infected-Recovered（DTM-SIR）model, and its simulation shows that the introduction of trust layer has positive significance to expand the impact of information dissemination.
