「社群媒體使用」、「社會網絡異質化」與「政治意見極化」關聯性之研究：以科技部傳播調查資料庫為例

Social Media, Network Heterogeneity, and Political Opinion Polarization: The View from Taiwan Communication Survey (TCS)

本研究以科技部傳播調查資料庫2015年第一期第四次調查資料作為資料分析來源，探討台灣民眾的「社群媒體使用」、「社會網絡異質化」與「政治意見極化」三者之間的關聯性。主要研究發現：（1）當台灣民眾使用社群媒體接觸公共事務的頻率「愈高」，一方面會呈現「較高」的公共事務意見網絡「異質性」，一方面也會呈現「較高」的「泛綠」人際社會網絡；（2）高度使用社群媒體接觸公共事務訊息的受訪者，會比低度使用或中度使用者有較高的「台灣認同」；（3）低度使用社群媒體接觸公共事務訊息的台灣民眾，會比中度使用或高度使用者，對於國民黨有較高的喜好度；（4）總結而言，台灣民眾如果愈頻繁透過社群媒體來瞭解政治或公共事務，則其「社會網絡」會傾向較為異質的意見資訊網絡、較為同質的泛綠人際網絡，「政治態度」也較為偏向泛綠（台灣認同、喜好民進黨）的政治意見氛圍。

This study used“Taiwan Communication Survey Database”(TCS) conducted in 2015 as a source of data analysis to explore the relationship between Taiwan’s people use of“social media”and their“social network heterogeneity”, as well as the relationship between people's“social network heterogeneity'' and their ''polarization of political opinions”.
This study suggests that: (1) people who use social media to understand public affairs will tend to be much more heterogeneous social networks; (2) people with more heterogeneous interpersonal social networks, their political opinions about ethnic identity will tend to be more likely on Taiwanese identity rather than Chinese identity. This result also implies that the more people use social media to contact public affairs information, the more their political attitudes and opinions seem to stand on the opposite side of the ruling power, and they tend to have a different political opinion atmosphere from the ruling authorities.
