Study on evolution of complex network of emergency information diffusion from perspective of social interaction
In order to reveal the complex rule characteristics of social subject interaction in information diffusion under the disaster emergency scenarios brought about by the reform of digital age,the network structures of emergency information diffu-sion with two attribute characteristics of small world and scale-free 2 were constructed respectively based on the social interac-tion theory and the complex network evolutionary game method.The numerical simulation modeling was used to analyze the influence of diffusion benefit,government guidance,information dissemination and other factors on the networks with different social interaction rules.The results show that the synergistic benefit under the positive diffusion and interaction spillover effect have obvious incentive for the positive behavior of subjects.The long average path and low clustering coefficient of scale-free interaction structure lead to its convergence rate under government guidance and benefit incentive is weaker than that of small world interaction network structure,but its power-law distribution characteristics lead to its rapid influence on the behavior of micro-subjects when the public opinion of opinion leaders breaks out.The government needs to adopt the corresponding guid-ance strategies to regulate the diffusion characteristics of different social interaction network structures.The research results can provide a theoretical reference for the government to guide the positive and effective diffusion of emergency information with classification policies.
