臺灣政黨傾向與社群媒體「選擇性接觸」

Abstract

社群媒體的時代來臨，對當代民主政治產生重大影響。尤其，許多出生自1990年代至2010年代者的青年族群，多屬於「數位原生世代」，亦可稱作「Z世代」；該族群之政治知識來源多來自於網路平台、社群媒體之上，這群國家未來的主人翁，在汲取政治知識、討論政治的過程能否包容多元意見誠為民主得否長遠、穩健發展的關鍵。因此，本文透過「問卷調查法」（questionnaire survey），抽樣調查我國18歲以上國人的社群平台使用行為，了解政黨傾向是否影響於各式社群平台（social media）上發表政治意見、汲取政治資訊，以及使用者立場感知一致等行為，並與「選擇性接觸」（selective exposure）理論對話。同時，也關照線上社群平台之使用是否更進一步影響具備政黨傾向者的線下政治參與程度？本文以「有序勝算對數模型」（ordered logit model）進行回歸分析，發現政黨傾向確實在對於在各社群平台的使用程度上產生不同程度的顯著影響。

The advent of social media has had a profound impact on contemporary democratic politics. In particular, many young people born between the 1990s and 2010s belong to the “digital native” generation, also known as “Generation Z.” This group often acquires political knowledge primarily through online platforms and social media. As the future stewards of the nation, whether they are able to tolerate diverse opinions during the process of acquiring and discussing political knowledge is a key factor in determining whether democracy can develop in a long-term and stable manner. Therefore, this study adopts a questionnaire survey approach to sample individuals aged 18 and over in Taiwan, investigating their behavior on social media platforms. It aims to examine whether political party preference influences behaviors such as expressing political opinions, acquiring political information, and perceiving alignment of viewpoints on various social media platforms. This study engages in a dialogue with the theory of selective exposure. At the same time, it also explores whether the use of online social platforms further affects the level of offline political participation among those with partisan preferences. Using an ordered logit model for regression analysis, the study finds that political party preference does indeed have a significant and varied impact on the level of engagement across different social media platforms.
