陳水扁雖然在2000年贏得總統選舉，然而，由於他並未取得過半選民的託付，再加上民進黨在國會並非最大黨，因此，由選舉聯盟轉換為執政聯盟的過程並不順利，特別是國會的立法結盟。2001年的二合一選舉包括立委、以及縣市長選舉，除了牽涉到下一任總統大選的護盤，也關係到國會生態的整。在這裡，我們了針對選舉過程的前後觀，也分別分析汎綠、汎藍陣營內部的各自競爭；再來，我們先檢視所謂的戰鬥內閣，繼而對於陳水扁執政兩年來的決策作初步的評析；最後，我們以為，除了必須對於當前的立委、及總統選制作適當的調整，以獲於穩定的政黨體系，總統與國會的定位也要進一步釐清。

　　　　　Even though Chen Shui-bian won the presidential election in 2000, he failed to receive the mandate of the majority of the voters. As a result, the process to transform his electoral coalition into the governing coalition had not moved without hindrances, especially the legislative one.

Finally, we will provide some thoughts on how electoral system and constitutional arrangements as well need to be adjusted in order to arrive at robust political institutions for political competitions.
