Abstract：In order to solve the problem of insufficient consideration of social class in the existing opinion dynamics studies, an opinion dynamics model based on the Hegselmann and Krause (HK) model is proposed by combining the topological properties of nodes in the network with the social structure on the basis of the heterogeneity of individual influences. In three types of classic complex network and an empirical network, three social structures are constructed with the social class division method adopted from the field of sociology according to capital. Simulation experiments demonstrate that the social structure has a significant impact on opinion evolution. Adjustment of the social structure through social policies is conducive to the consensus of opinions. To study the inconsistency of opinion evolution in the same type of social structure in the actual society, different initial opinion distributions of upper-class individuals are set up in the type-B pyramidal and olive-shaped social structures. It is inferred that the polarization and unification of upper-class individuals’ opinions will influence the polarization and unification of public opinion correspondingly.
