本文从“话语表征”和“叙事建构”的视角出发,对新浪微博上有关新闻自由的讨 论与文本进行个案研究,旨在通过此个案揭示和反思微博话语如何建构关于新闻自由的 意义。文章首先考察了作为论述和讨论主体的微博用户的身份特征,并以此身份特征为 基点,分析关于新闻自由话语的叙事模式和话语实践。研究发现,在微博话语空间内, 人们主要是从以下三个维度出发谈论新闻自由:一是从政府、媒介和公众三者的矛盾关 系出发阐释新闻自由;二是关于新闻自由话语的悲观主义与怀旧主义色彩;三是叙事模 式的美国中心主义倾向。在这三个维度的基础上,新闻自由在表征体系中的主要建构方 式有如下几种:一是建构差异;二是建构相似性;三是设立参照物;四是重设语境;五 是填充实例。
