自從政府拋出在核四公投實施不在籍投票的可能性之後，該制度再度成為輿論的焦點。儘管各界對於不在籍投票的討論由來已久，但因為資料過時，或題目範圍限制，所以參考價值有限，也替該主題之研究留下可待發展的空間。本文從政治、法律、社會和行政層面，分析我國實施不在籍投票所涉及的各項問題，以了解該制度實施之可行性，並就制度規劃提出建議，希望透過學術性和實務性的分析，裨益不在籍投票的研究與政策推動，並提出相關研究的新議題。

The absentee voting system becomes the focus of the public opinion again after the government announced the possibility of adoption of the voting system for the referendum on nuclear power policy early this year. Researches are still few although the absentee voting system has been discussing for long in Taiwan. This paper analyzes various issues concerning the implementation of the absentee voting system in this country through political, legal, social, and administrative discussions, so as to benefit academic as well as policy works. Future research agendas are also provided hereby.
