在2014年3月的太陽花學運裡，參與的學生在此次扮演主要的角色。也因為如此，各領域響起許多質疑的聲浪，認為此運動只匯集了較邊緣的社會思想，尤其是極端反中的論點。這使得太陽花學運帶著不透明性，真正發起和參與的學生動機變得難以捉摸。此論文採用各方觀點加以探討，並分類大學生參與之背後的真正原由。研究首先細化就讀大學之參與者的動機，參考其投入程度，加以比較各種參加的原因；次而探討其學歷背景是否因而對其造成影響。本研究運用這兩項方法比對，釐清參與學生之背景、動機、成果的交互影響之關係。 / During the Sunflower Movement of March 2014, it was the university students that played a prominent role. Because of this, several misconceptions about the Sunflower Movement arose. Among them was that it only appealed to a small radical fringe of society, especially those with strong anti-Chinese sentiments. This cast a shadow on the movement as a whole, and the true motivations why students became involved was unclear. This paper takes a multi-dimensional approach to specifying the reasons behind why students participated. First, it breaks down the various motivations students had and compares this with how invested they became in the movement. Secondly, it takes into account students’ backgrounds to see whether or not this affected their motivations. Using this approach, we can see a relation between one’s background, motivations, and their eventual outcome in protest.
