本文在传染病模型(SIR)的基础上,从宏观和动态的视角出发,通过建立口碑效应作用下的品牌扩散传播模型,采用数值计算和图形观察相结合的方法,描述口碑作用下的品牌扩散传播过程,分析市场上品牌消费者比例随着口碑作用和时间推移的变化规律,并预测品牌市场占有率达到最高的时刻及品牌扩散程度,并探讨了品牌推广的手段以及影响品牌传播的因素,为企业有效开展品牌的口碑营销和品牌推广提出相应的建议。
Based on the SIR model, this paper sets up a model of brand communication under the influence of WOM from a microscopic and dynamic perspective. We integrate the methods of literature review, quantitative research and figure analysis to describe the influence of WOM to Brand Communication, and find out the variation regularity of consumers' ratio of a certain brand, and forecast the time when a certain brand gets the highest market share. In addition, several suggestions of WOM marketing and brand promotion are given.
