選制知識對投票參與的影響

Knowledge of the Electoral System and Voter Turnout

立法院在2008年第七屆立法委員選舉中，首次採用了單一選區兩票制（Mixed-Member Majoritarian Electoral System, MMM），其結合了單一選區多數決與政黨名單比例代表制兩種席次分配方式，與過去採用的「複數選區單記非讓渡投票制」（Single Non-TransferableVote with Multi-Member-District system, SNTV-MMD）在制度特性上截然不同。本文主要目的是檢視選民對於新選制的瞭解，亦即選制知識的高低，是否將對選民之投票參與產生影響。

Taiwan’s new MMM legislative electoral system first implemented in 2008 was a sharp departure from the half-century long SNTV system. This paper examines effects of knowledge of the new electoral system on citizens’ decisions to vote or not to vote. Existing literature on voting either assumes that voters are fully aware of the electoral system and thus ignores the effect of knowledge or at bestassumes it is an exogenous factor. This study distinguishes itself from other related works in three respects. First, we do not assume that voters are fully.
