本研究从网络性别议题中群体极化现象出发，选取了“唐山打人事件”作为个案，运用集体行动框架理论，通过框架分析的方法对极化现象进行研究，从而对近年来性别议题中的争议与分裂进行厘清。本研究聚焦于两个核心研究问题：（1）在网络性别议题中呈现出了什么样的性别话语与反性别话语；（2）这些话语是如何建构、如何互动的？从这两个问题出发对极化现象进行探讨。针对不同的研究问题，本文将研究设计分为文本框架分析与话语的架构分析两部分。首先，通过对微博平台上的有关内容进行量化分析，将性别讨论归纳为 8 个表达框架。同时，对不同框架下对应的微博评论态度进行编码，考察总体的态度分布与极化程度。其次，运用架构分析，以“核心架构任务”的概念为抓手，通过“话语过程”、“框架整合过程”与“争议性过程”的分析，考察了性别话语的构建策略，对不同话语互动过程进行了探索，并总结了其特征与脉络。研究有三个主要发现，第一，从总体舆论分布上看，性别议题中的极化态度并不明显，但是不同框架间的极化程度有显著差异。第二，基于本文研究个案的网络性别话语，主要是围绕不公框架建立的一套抗争性话语，并呈现出窄化与单一的发展趋势。第三，通过探讨性别与反性别话语的互动过程，认为极化现象并非由不同观念本身的差异决定，而与不同框架间对解释框架的争夺过程有关。最后，根据框架整合的概念，从框架的三个层次提出了主流媒体的舆论治理建议。

Starting from the phenomenon of group polarization in Internet gender issues, this study selects "Tangshan beating Incident" as a case, based on the Theory of Collective Action Frames, and studies the phenomenon of polarization through the method of frame analysis,so as to clarify the disputes and divisions in gender issues in recent years. This research focuses on two core research questions: (1) what kind of gender discourse and anti-gender discourse are presented in online gender issues; (2) How are these discourses constructed and interacted? The polarization phenomenon is discussed from these two problems. Aiming at different research problems, this paper divides the research design into two parts:text frame analysis and discourse structure analysis. Firstly, through the quantitative analysis of the relevant content on Weibo platform,gender discussion is summarized into eight expression frameworks. At the same time, the corresponding Weibo comment attitudes under different frameworks were coded to investigate the overall attitude distribution and degree of polarization. Secondly, using structure analysis, starting with the concept of "core framing task", through the analysis of "discourse process", "strategic process" and "controversial process", this paper examines the construction strategies of gender discourse, explores the interaction process of different discourse, and summarizes its characteristics and context. The research has three main findings. First, from the general distribution of public opinion, the polarization of gender issues is not obvious, but the degree of polarization between different frameworks is significantly different. Second, the online gender discourse based on the cases studied in this paper is mainly a set of defiant discourse built around the framework of injustice, and shows a trend of narrowing and singleness. Thirdly, by exploring the interactive process of gender and anti-gender discourse, it is concluded that the polarization phenomenon is not determined by the differences of different ideas, but is related to the competition for explanatory frames among different frames.
