【摘要】：谣言传播是复杂网络传播动力学研究的重要课题.分析正负双重社会强化机制对用户传播行为的影响,并根据不同网络度分布的差异,构建了同质网络与异质网络谣言传播动力学模型,进而分析谣言传播阈值及最终扩散规模.数值仿真结果表明,在线社交网络谣言传播阈值很小,谣言一旦产生极易传播;正负双重社会强化机制同时影响谣言最终传播规模;加大负向社会强化效用,有助于缩小谣言传播的最终扩散范围,削弱谣言产生的最大影响,同时还可以减缓谣言传播速度,为有关部门采取措施控制谣言传播提供更充裕的时间.研究结果告诫政府有关部门,只有下大力度加大负向社会强化效用,才能有效控制谣言传播,维护国家安全与社会稳定.
[Abstract]:Rumor propagation is an important subject in the study of complex network communication dynamics. This paper analyzes the influence of positive and negative social reinforcement mechanism on user communication behavior and according to the different distribution of network degree. The dynamic model of rumor propagation in homogeneous network and heterogeneous network is constructed, and then the threshold of rumor propagation and the final spreading scale are analyzed. The numerical simulation results show that the threshold of rumor propagation in online social networks is very small. Once the rumor is produced, it is easy to spread. The positive and negative social strengthening mechanism also influences the scale of the final spread of rumors; Increasing the negative social strengthening effect will help to narrow the scope of the final spread of rumors, weaken the biggest impact of rumors, but also slow down the spread of rumors. For the relevant departments to take measures to control the spread of rumors to provide more time. The results of the study warned the relevant government departments, only by making great efforts to increase the negative social strengthening effect, can we effectively control the spread of rumors. Maintain national security and social stability.

【正文快照】： 1引言随着信息时代的到来,谣言已经渗透到社会生活的方方面面.谣言产生于模糊的、危险的或者存在潜在威胁的环境中,在人们“宁可信其有,不可信其无”的潜意识下,往往在未经证实的情况下就被人们广为传述[1],从而对公众的态度、信念、行为产生重大而深远的影响[2].特别是Facebo
