摘　　要：近年来,互联网特别是社交媒体在台湾地区政治中所扮演的角色愈发关键。本文以2016年台湾地区选举期间脸书(Facebook)平台上的政治讨论为研究对象,为候选人与参加讨论的普通互联网用户绘制社会网络,并结合社会网络可视化、聚类分析及超链接分析等研究手法,对社交媒体政治社区进行分析。台湾地区的社交媒体政治社区同时呈现了政治极化与大规模信息渗透两种现象:一方面,参加政治讨论的互联网用户根据各自的意识形态相互隔离;另一方面,针对对方政治阵营的信息渗透尝试却已成为普遍现象。然而,在政治人物主导的星形结构社会网络中,这些通过边缘个体传播的异质信息仍不足以打破“信息茧房”。Social media play a key role in Taiwan residents politics nowadays.This study investigates the social networks of Facebook users in political campaigns and the clustering of communities with different political orientations during 2016 elections in Taiwan.The results,from the combined one-mode social network analysis and shared URLs analysis,reveal the two characteristics of the Taiwan residents political communities on Facebook:political polarization and large-scale information infiltration.Social media users are segregated into different communities based on political ideologies,while they make attempts to infiltrate the opposition camps.However,information from opposition sources spread by common users rarely results in the breaking out of“information cocoons”dominated by influential politicians.
