Abstract:

In view of the fact that the existing studies rarely consider the competitive propagation pattern and formal publishing mechanism of multi-heterogeneous information that exist when there are occurrence time differences under emergencies, this paper first analyzes the information types, propagation stages and competitive characteristics in this situation in combination with real cases, and then proposes a two-stage propagation framework and the research theme. Next, based on the construction ideas of logistic growth model and LotkaVolterra competition model, a two-stage competition propagation model of informal and formal information is constructed, and the equilibrium points and their stability conditions of the model are derived afterwards. Finally, the simulation and case analysis are conducted to verify the validity of the proposed model and its derivation results, and then the way that publishing time and intensity of formal information influences the evolution of competitive relationships among multi-heterogeneous information is investigated.

Key words: emergencies, occurrence time differences, heterogeneous information, competitive propagation
