摘要
基于风险的社会建构和风险的社会放大理论,本研究提出了"风险的社会扩散框架",重点讨论信息传播在风险扩散中的关键作用,旨在从信息转发的微观层面揭示风险扩散的生成机理.研究发现,网络突发事件的初始热度对信息扩散的次数具有正向推动作用;以意见领袖为主的重复发帖用户的数量越多,越能够带动信息扩散到不同的社区;用户的重复发帖次数在事件爆发初期对信息扩散次数有推动作用,但随着重复发帖次数增加,效果变得有限.
Abstract
Drawing on the theories of social construction of risk and social amplification of risk,this study proposes a"Social Diffusion Framework of Risk(SDRF)",with a particular focus on the pivotal role of information dissemination in the diffusion of risk.Using complex network analysis,this study examines the phenomenon of multi-level information diffusion during emergencies on Weibo,aiming to reveal the generative mechanism of social diffusion of risk from the micro-perspective of information retransmission.The study found that the initial popularity of information about network emergencies has a positive impact on the frequency of information diffusion.The greater the number of repeat posting users,especially those who are opinion leaders,the more frequent the information diffusion will be,and the more likely it is to drive the information to spread to different communities.During the initial outbreak of an event,the frequency of users reposting information has a positive impact on the number of times the information is diffused.However,as the number of reposts increases,the effect becomes increasingly limited.
