Abstract：Social public opinions transfer from the real society to the network space, resulting in the emergence of network public opinion events. Online public opinion diffusion reverses the contrast between the support and opposition of public opinions, and finally changes the initial decision of interest groups, which is called the structure reversal of online public opinion. In order to explore the complex systems mechanism underlying this phenomenon, we established a network public opinion structure reversal model based on the Deffuant model. The Deffuant model is modified from two aspects: one is to transform the individual′s own opinion value into the perception opinion value in the interaction; the other is to introduce the influence of social transformation from a macro perspective. The simulation results show that social transformation factors positively influence the diffusion of online public opinion. The higher the degree of social transformation, the higher diffusion of public opinion in structure reversal. Heterogeneity level positively delays the public opinion structure reversal. The larger the size of interest groups, the more difficult it is to complete public opinion structure reversal. The model proposed in this paper can explain the structural reversal phenomenon of public opinion diffusion to a certain extent and can provide certain theoretical reference and decision support for the control of network public opinion in practice.
