To understand why this was so, one should note that the electoral changes have cut the number of seats in the Legislative Yuan from 225 to 113, reduced the size of voting districts, and increased their number; each district can now elect only one representative. For example, Taipei County, which previously had three districts and 28 representatives, now has 12 districts but only 12 representatives.
推究原因，本次為我國「國會減半／單一選區兩票制」首度實施，國會席次由原有的 225 席減半為 113 席，選區則幅員縮小而數量增加，同時每個選區僅能選出 1 人（如台北縣由原先之 3 個選區／應選 28 人，改制為 12 個選區／應選 12 人）。
