摘要
食品安全网络舆情是公众参与食品安全监管的重要平台,若不加以科学的监管与引导,极易引发食品安全恐慌心理,甚至危害社会稳定。微博是食品安全网络舆情中重要的自媒体平台,主要通过微博转发行为扩散舆情事件的影响,推动舆情事件的发展。为了深入分析食品安全网络舆情中网民微博转发行为,本文以上海福喜事件为例,在事件发展与关注度分析的基础上,通过采集上海福喜事件的新浪微博数据,并运用多项Logistic回归模型展开分析,探讨网民在食品安全网络舆情中转发行为的特征与主要影响因素。研究结果表明,对于仅有主帖内容的微博(类型Ⅰ微博),发帖者微博的粉丝数、微博数、认证情况以及发帖者微博内容的情感倾向、是否有链接、是否有视频对其微博的被转发次数有显著影响;对于转发了他人内容的微博(类型Ⅱ微博),发帖者微博的粉丝数、微博数、认证情况、被转发者微博的粉丝数、被转发次数、被转发者微博内容是否有链接对发帖者微博的被转发次数有显著影响;基于上述结论,提出如下政策建议:具有较高粉丝数与微博数的微博用户所发布的微博影响力更大,应进一步加强对该类微博用户的关注,尤其是一些微博"大V";同时,应进一步发挥官方认证微博在舆论引导方面的积极作用;在舆论引导的过程中,可以通过诸如同时发布相关链接、视频等方式,提高微博内容形式的多元化程度,以增强微博的影响力;此外,在发布微博的过程中,客观、公正地表明态度立场,也是提高微博舆论引导作用的重要方面。
