Because the areas of jurisdiction of the Taiwan Provincial Government and, in the present period, of the Central Government really are too similar (their two jurisdictions overlap to 98 % in terms of area and 80 % in terms of population1), many scholars and Legislative Yuan members question whether maintaining the present four-tier structure (see table), with all its complexities, is still really necessary.
也正因為台灣省政府和現階段中央政府的轄區實在太過接近（兩者轄區面積有九十八％重疊、人口有八十％重疊！），因此從結構面來說，不少學者與立法委員都質疑，現今維持四級制（見附表），體制繁複，是否有必要？
