誰支持婚姻平權？探索臺灣婚姻平權的支持基礎

Who Supports Same-sex Marriage? Exploring the Mass Bases of the Same-sex Marriage Issue in Taiwan

近年來婚姻平權議題受到臺灣社會大眾廣泛討論與重視，成為重要議題，因此本研究試圖解析婚姻平權的支持基礎。首先，從臺灣婚姻平權議題的發展脈絡出發，檢視1991～2017年民意發展趨勢。其次，透過模型分析探究民眾婚姻平權態度的差異，是來自於社會結構還是家庭價值觀的不同，又或是政黨政治動員的結果。研究結果顯示民眾對婚姻平權的態度正處於震盪期，對婚姻平權議題的支持不僅是因其所處的社會結構位置與身分，亦是立基於對多元家庭價值觀的支持，並同時受到特定政黨認同影響；此意謂著婚姻平權在臺灣已正式轉變為政治議題。

In recent years, same-sex marriage has become an important issue in Taiwan. This study aimed to explore the bases of support for same-sex marriage. First, we reviewed the contexts of same-sex marriage discussions in Taiwan and demonstrated the distribution of people’s preferences between the years 1991 and 2017. Second, we applied an ordered logit model to examine whether social structures, family values, and party identification affect people’s attitude toward same-sex marriage. The research findings indicate that public opinion of same-sex marriage is in a turbulent period, and people support same-sex marriage based not only on demographic factors, but also on pluralistic family values and party identification. This finding confirms that same-sex marriage has formally become a political issue in Taiwan.
