社會資本近年來被視爲現代公民應具備的優良特質，咸認爲 一旦社會資本缺乏，參與低落，會危及民主的素質。本研究以西 方近年的社會資本概念來探究我國大學生的社會資本，並希望掌 握我國大學生社會資本與媒介行爲及政治信任對象之關係。 本研究以威斯康辛大學學者界定的社會資本三層面來測量台 灣大學生的社會資本，利用問卷調查法，在2002年北高市長選舉 後抽樣調查我國大學生的政治信任與投票。而這些政治行爲、態 度與其媒介使用行爲與社會信任之關係爲何？結果發現社會資本 中的生命滿意與人際信任的高低明顯與信任陳水爲總統、司法體 系及立法院有關，生命滿意的大學生呈現較高的政治信任，媒體 使用時間與政治信任無關，而政媒使用（政論/資訊相關媒體内 容的接觸及意見表達）則與信任立法院與司法體系有關。

This study explores Taiwanese college studentsJ media use, social capital, and political trust. It is assumed that Chinese students living in Taiwan will demonstrate a differing picture of social capital when compared to those students of equivalent background in the West. The students' social capital is examined via three perspectives: interpersonal trust (trust of relatives, classmates, neighbors, etc.), life satisfaction (contentment with respect to present condition and future prospects), and in terms of association capital (participating in associations and feeling influential in the group). It is hypothesized that college students' media use and social capital could predict their trust toward the President, Legislation Yuan, Judiciary Yuan, and then-voting behavior. The results show that students' life satisfaction and interpersonal trust are significantly related to their political trust. It is found, however, that social capital is not related to students' voting or whether they voted on Election Day.
