國內學者已經累積相當多關於民主價值、政治支持、民主滿意度 等研究，而且經常討論政治信任的成因以及影響，但是較少觸及各種 政治機構或組織的信任，尤其是對於政黨的信任。本研究以台灣民眾 為研究對象，探討對於政黨的信任此一概念。信任指的是對於政治事 物具有一定的信念，也是其正當性，因此民眾對於政黨的信任程度， 類同於法院、總統、立法院等制度的信任度。理論假設為民眾對政黨 功能的評估影響其對政黨的信任度，而對政黨的信任也將進一步影響 對於民主政治的滿意度。本研究所探用的資料為政大選舉研究中心於 2008年所執行的全國性電話訪問調查。主要發現是台灣民眾對政黨 及各個政治機構的信任度不高，但是對政府機構之間的信任度具有中 等程度的一致性，顯示民眾對政治機構間的信任度相互關聯，同時民 眾對政黨功能的看法影響政黨信任度高低，愈肯定政黨功能者，有愈 高的機率信任政黨。政黨信任度則進一步解釋民眾對民主政治的滿意 度，對政黨愈信任者，有較高的機率滿意民主政治的運作。

A supportive belief is the key element for a healthy democracy. Much research on democratic values, political support and satisfaction with democracy has been done in Taiwan. Most of them are studies on the cause and effect on political trust, but only a few examines the trust of political institutions, not to mention the trust of political parties. By using data from a nation-wide telephone interview in 2008, this article aims to examine the concept of political party trust among the Taiwanese electorate. We believe that the degree of political party trust is derived from how citizens evaluate the functions of political parties in Taiwan. The degree of political party trust in turn will have a significant effect on citizens’ attitudes toward the democratic process. The results demonstrate that few people trust parties. This distrust is partly a result of how people evaluate the political parties. Citizens with positive judgments on political parties tend to have higher trust. The results, moreover, show that the degree of party trust contributes to the satisfaction with the democratic process.
