【摘要】 随着全国各地马拉松赛事日益增多，赛事中突发事件发生的概率以及可能引发的网络舆情风险也随之上升。为有效引导马拉松赛事突发事件的舆情演化，本采用文献资料法、逻辑分析法等研究法，从主体、客体与中介方面分析了马拉松赛事突发事件网络舆情的影响因素，梳理了大众传媒与官方组织两大舆情传播渠道，总结了传播途径多元、信息内容丰富、同类信息快速扩散的舆情传播特点，并将舆情发展划分为形成、爆发、稳定、消减、焦点转移5个阶段。在此基础上，构建并提出包含监督机制、处置机制、善后协调机制在内的舆情应急管理体系，旨在减缓舆情发酵、缩短舆情持续周期。更多还原

【Abstract】 As marathon events continue to proliferate nationwide,the probability of incidents and their potential to trigger online public opinion risks has also increased. To better manage the evolution of public opinion following such incidents,this study applies methods including literature research and logical analysis to examine influencing factors from subject,object,and intermediary dimensions. It identifies two primary communication channels,mass media and official organizations,and summarizes key characteristics of online opinion dissemination,such as multi-channel diffusion,diverse information content,and rapid spread of similar information. The evolution of public opinion is categorized into five stages: formation,outbreak,stabilization,decline,and focal shift. Building on this analysis,the study proposes an incident public opinion management system comprising monitoring,response,and post-event coordination mechanisms,designed to curb escalation and shorten the lifecycle of negative sentiment.更多还原
