解釋同性婚姻合法化的民意基礎

Explaining the Public Opinion Basis for the Legalization of Same-Sex Marriage

本研究的主要目的在於探索台灣同性婚姻合法化的民意基礎，參酌以往文獻與我國民情，本文提出七個研究假設，包括女性、年輕世代、教育程度高者與泛綠政黨認同者皆傾向支持同性婚姻，基督教、回教與天主教信仰者則傾向反對同性婚姻；與同性戀者的接觸頻率高者傾向支持同性婚姻，人格特質中的開放性、審慎性則分別與支持同性婚姻有正向、反向的顯著關係。利用2018年同性婚姻公投案舉行後所執行的電話訪問資料，檢驗本文所提出的研究假設。結果顯示，除了泛綠政黨認同者（相對於無政黨認同者）傾向支持同性婚姻的假設未達統計上的顯著水準之外，其他假設皆獲得證實。

The primary objective of this study is to explore the public opinion basis for the legalization of same-sex marriage in Taiwan. Drawing on previous literature and the unique sociopolitical context of Taiwan, this study proposes seven hypotheses: women, younger generations, individuals with higher education levels, and supporters of pan-green political parties are more likely to support same-sex marriage, while individuals with Christian, Islamic, or Catholic religious affiliations are more likely to oppose it. Additionally, those with higher frequencies of interpersonal contact with homosexual individuals tend to support same-sex marriage. Among personality traits, openness is positively associated with support for same-sex marriage, while conscientiousness shows a significant negative relationship. This study tests these hypotheses using telephone survey data collected after the 2018 referendum on same-sex marriage in Taiwan. The findings confirm all hypotheses except for the one suggesting that supporters of pan-green political parties (compared to those with no political affiliation) are more likely to support same-sex marriage, which did not reach statistical significance.
