：文章在分析消费者意见领袖特征作用量、社会网络要素作用量、普通消费者特征作用量对消费者意见领袖影响力作用的基础上，结合系统动力学、传播学、社交网络等相关知识，分析了消费者意见领袖影响力，阐述其变化机制和影响要素，同时划分边界构建系统动力学模型，使用Vensim PLE软件对模型进行仿真及灵敏度分析比较各系统参数的变化对消费者意见领袖影响力的影响。研究结果表明，消费者意见领袖特征相关要素、社会网络相关要素及普通消费者相关要素均可通过影响消费者意见领袖影响力进而影响网络口碑及消费者行为。

On the basis of analyzing the influence of consumer opinion leaders' characteristics, social network factors and consumers' characteristics on consumer opinion leaders, system dynamics, communication, social network and other related knowledge are used to analyze the influence of consumer opinion leaders, and then the mechanism and influence factors are expounded. Boundaries are divided to build system dynamics model, and the model is simulated and sensitivity analysis is conducted with Vensim PLE to compare the impact of changes in system parameters on the influence of consumer opinion leaders. The results show that the factors related to the characteristics of consumer opinion leaders, factors related to social network and consumers could influence the consumer opinion leaders with words and consumer behavior.
