摘　　要：[研究目的]网络舆情中信息间的竞争传播更符合社交网络的真实情境,研究舆情事件中多元信息竞争传播的演化机制有助于政府和媒体有效监控舆情、引导舆论。[研究方法]结合舆情事件多信息传播特点,加入信息犹豫者和信息接触率,构建二元信息竞争的SH2IR模型,仿真同步和异步情景下二元信息的竞争演化过程。[研究结论]研究表明,在同步传播模式下,单独增强信息接触率、传播转化率、犹豫转化率以及置换率,都可以扩大信息的传播;在异步传播模式下,信息发布的越早,传播范围越广,但单独增强传播参数对传播效果影响较弱,同时提高信息的传播参数时传播行为明显加强。[Research purpose]The competitive communication between different information in online public opinion is more in line with the real situation of social network.The study on the evolution mechanism of multi-information competitive communication in public opinion events is helpful for the government and media to effectively monitor public opinion and guide public opinion.[Research method]Combined with the characteristics of multi-information transmission of public opinion events,the SH2IR model of binary information competition was built by adding information hesitant and information contact rate,and the evolution process of information competition under synchronous and asynchronous scenarios was simulated.[Research conclusion]In synchronous transmission mode,the information transmission can be expanded by independently enhancing the information contact rate,transmission conversion rate,hesitation conversion rate and replacement rate.In asynchronous transmission mode,the earlier the information is released,the wider the transmission range is.However,the influence on the transmission effect is weak when the transmission parameters are enhanced alone,and the transmission behavior is significantly strengthened when the transmission parameters are increased simultaneously.
