For the first time in the history of Taiwan, most members of the Legislative Yuan were to be elected from single-member districts: 73 of the 113 members were chosen in such districts by the plurality voting system (first-past-the-post). Parallel to the single member constituencies, 34 seats under an Additional Member System were elected in one national district by party-list proportional representation. For these seats, only political parties whose votes exceed a five percent threshold were eligible for the allocation. Six further seats were reserved for Taiwanese aborigines. Therefore, each elector had two ballots under parallel voting.
