政治知識直接或間接地影響公民的政治評價及政治參與行為。本文使用2001年立法委員選舉選後的問卷調查資料，除了對政治知識的來源加以剖析外，也試圖指出政治知識對政治評價的影響，籍以瞭解其間的因果關聯，進而對政治知識與政治行為的整體研究架構來進行模型檢測。結果發現政治知識可以充分地解釋政治評價，而政治評價則又進一步地影響政治行為。政治評價，不論是對經濟的表現或對主要政黨的評價，均受到政治知識的影響。若是把政治知識作為政治評價主要的解釋項，也沒有因社會人口變數的引進而對政治評價有改變。而在2001年立法委員的選舉研究中發現，在控制其他變數下，政治評價也影響受訪者投票的選擇。

That political knowledge may have impacts on political evaluation and political evaluation may affect voting choice have been speculated. Using post-election survey data of the 2001 legislative election, this research intends to explore the explanatory factors that influence political knowledge, to identify the relationship between political knowledge and political evaluation, and to link political evaluation and voting choice. The results show that political knowledge has significant impacts on political evaluation, and political evaluation influences the legislative vote choice. Political evaluation, both the evaluation of economic performance and the evaluation of major parties, influenced by political knowledge independently form socio-demographical factors. After analyzing the full model, we confirmed that political evaluation has impacts on voting choice.
