摘要
本文以政黨情感好惡差距為指標，觀察台灣社會大眾的政治分歧程度。有別於過去文獻，本研究使用人格特質為主要解釋變數，驗證其是否會對政黨情感好惡的差距產生顯著的影響。研究採用電話訪問法，總計成功蒐集有效樣本1,601份。本文提出的研究假設，包括人格特質對於形塑國、民兩黨情感好惡的直接效果與調節效果。研究發現審慎性對於政黨情感好惡具顯著直接效果，審慎性愈高者，傾向對於國、民兩黨情感好惡差距愈大。此外，實證資料也發現，三項人格特質皆具顯著的調節效果，外向性、審慎性愈高者，會提升政黨認同強弱度對國、民兩黨情感好惡差距的影響力；而宜人性愈高者，則會降低政黨認同強弱度對國、民兩黨情感好惡差距的影響力。

This study applies partisan affect as an indicator to understand the political cleavage in Taiwan. The main purpose is to examine whether personality traits exert significant effects on shaping partisan affect. By means of telephone interviews, the research team successfully collected 1,601 samples. Hypotheses raised by this study focus on the direct and the moderating effects of personality traits on partisan affect. According to empirical evidence, conscientiousness exerts a positive and direct effect on partisan affect. Stronger conscientiousness leads to a larger difference of partisan affect. In addition, the moderating effects of three personality traits are demonstrated. Both conscientiousness and extroversion benefit the influence of party identification on partisan affect. In contrast, agreeableness reduces the effect of party identification on partisan affect.
