摘　　要：网络论坛中的公共议题上升在舆论形成过程中发挥着重要的作用。本研究探讨了网络论坛中的公共表达的结构,致力于明晰公共议题成功上升的结构性特征。本研究从国内某知名网络论坛中选取样本,分析了3000多个帖子。结果显示,参与的异质性、集中度和早期的密集回复有助于形成更大的讨论串。本模型能解释讨论串中帖子数量68.5%的变异。本研究的结果表明,公共表达的结构是公共议题上升的关键因素。The rise of public issues in Internet forums plays an important role in the formation of public opinion. This paper intended to investigate the structure of public expressions in Internet forums, and aimed to detect the structural characteristics of the successful rise of public issues by analyzing more than 3,000 posts collected from a famous Chinese Internet forum. The results suggested that participation heterogeneity, concentration, and intensive replies at the early stage were associated with a higher probability of successful thread building. The model could explain 68. 5 variance of the number of posts in the thread. The results implied that the structure of public expression is crucial for the rise of public issues.
