摘要
为解决现有观点演化研究对社会阶层考虑不够充分的问题,在个体异质性影响力的基础上,将网络中节点的拓扑性质与社会结构结合,提出了一种基于HK模型的观点演化模型。在3种经典复杂网络和一个实证网络中,采用社会学领域中根据资本划分社会阶层的方法,构建了3种社会结构。利用仿真实验,发现社会结构对观点演化具有重大影响,通过社会政策调整社会结构有利于观点达到一致。为研究现实社会同一类型社会结构中观点演化不一致的情况,在B型金字塔和橄榄型社会结构下,设置高阶层个体不同的初始观点分布,发现高阶层个体观点的极化和统一会相应地影响舆论的极化和一致。
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.
