基于社会网络理论,构建出网络舆情传播的心理阈值模型,采用Agent方法在无标度网络中模拟调节焦点、社群认同、关系强度等因素对舆情传播水平和速度的影响作用,从“个体-社群-网络”三个层次探究网络舆情传播机制。结果表明:与防御型和混合型相比,促进型调节焦点网络中的舆情传播水平和速度最高;低社群认同和弱关系环境更有利于网络舆情传播水平和速度的提升;网络构成对舆情传播水平和速度有倒U型关系,社群认同、调节焦点对这种关系有调节作用。
Based on the theory of social network, this paper constructs the psychological threshold model of network public opinion dissemination, and uses Agent method to simulate the focus of adjustment in scale-free network, the influence of social identity and relationship strength on the level and speed of public opinion dissemination. - Community - Network "three levels to explore the network public opinion transmission mechanism. The results show that compared with the defensive and hybrid models, the promotion and regulation of the focus network have the highest level and speed of public opinion dissemination; the low community identification and the weak relationship environment are more conducive to the improvement of the level and speed of network public opinion dissemination; There is an inverted U-shaped relationship between the level and speed of communication. The community agrees that the focus of regulation has a regulatory effect on this relationship.
