The underlying mechanisms of online political discussions which may involve power dynamics have seldom been explored through a dynamic network approach, even though discussions themselves are inherently relational and dynamic processes. It remains unclear how discussions are shaped over time between egos/alters with different political/sociopsychological/linguistic attributes as well as by the existing discussion ties surrounding them. Based on a stochastic actor-oriented modeling constructed from pre-survey/virtual discussion/post-survey data, we found some evidence that, in the politically heterogeneous context, shared political ideology, alter’s political tolerance level, and the extent of negative/strong/assertive language used by alter are associated with the likelihood of discussion tie creation/maintenance. In the homogeneous context, the extent to which ego perceives alter as politically knowledgeable and personally likable was clearly associated with ego’s tendency to create or maintain discussion ties with alter over time. This study uncovers alter/dyad-centered variables that are critical, but have been overlooked, for communication research.

解析在线政治讨论的网络动态：具有政治/社会心理/语言因素的随机行为者导向模型

尽管讨论本身本质上是关系性和动态过程，但很少通过动态网络方法来探索可能涉及权力动态的在线政治讨论的基本机制。目前尚不清楚具有不同政治/社会心理学/语言属性的自我/改变之间的讨论如何随着时间的推移以及围绕它们的现有讨论关系而形成。基于根据调查前/虚拟讨论/调查后数据构建的面向行动者的随机模型，我们发现了一些证据，表明在政治异质背景下，共同的政治意识形态、改变的政治容忍度以及负面/强烈的程度alter 使用的/断言语言与讨论关系创建/维护的可能性相关。在同质背景下，自我将改变者视为政治知识渊博且个人讨人喜欢的程度显然与自我随着时间的推移与改变者建立或维持讨论关系的倾向相关。这项研究揭示了以改变/二元为中心的变量，这些变量对于传播研究至关重要，但一直被忽视。
