有效的危机信息传播在危机管理中至关重要。为了研究危机信息在不同传播方式下的扩散特征,本文基于BA SS模型,构建了公共危机事件后正确信息与谣言信息的扩散模型,并通过M atlab软件模拟了不同参数条件下两类信息的扩散规律及扩散状态差异。分析结果表明,两类信息扩散曲线的增长幅度受到渠道系数的影响,最终的扩散规模与非正式渠道信息准确度存在正相关的关系。要提高危机信息传播的有效性,危机管理部门可以从扩大正式渠道的覆盖范围、提高信息发布的准确性与权威性、加强公众的应急素质教育以及转变谣言管理态度等方面入手。
Effective Crisis Information dissemination is crucial in crisis management. In order to study the diffusion characteristics of crisis information under different modes of transmission, this paper constructs a diffusion model of the correct information and rumor information after public crisis based on the BA SS model and simulates the diffusion of two kinds of information under different parameters by M atlab software Differences in laws and proliferation status. The results show that the growth rate of the two types of information diffusion curve is affected by the channel coefficient, and the final diffusion scale has a positive correlation with the informal channel information accuracy. To improve the effectiveness of crisis information dissemination, crisis management departments should start with expanding the coverage of formal channels, improving the accuracy and authority of information dissemination, strengthening the public’s emergency quality education and changing rumor management attitudes.
