本文認為，當前台灣政治所面臨的因境與挑戰，主要源於2000年政黨輪替朝野易位之後，政黨政治無法良性及有效運作的結果，而非民主體制的運作與價值受到質疑。2000年之後，台灣政治發展所面臨的僵局，主要反映出政黨自我角色定位與調適的困難，以及政黨之間互動的摩擦與對立，而當前憲政制度的瑕疵，更是讓政黨之間不易擺脫惡鬥對立的一項重要因素。

This paper proposes that the political difficulties and challenges faced currently by Taiwan are due mainly to events following the transfer of power to the opposition in 2000. Theses difficulties can be attributed to the dysfunction of party rather than the functioning or the values of a democratic system being called into question. After 2000, Taiwan politics were deadlocked due to problems that arose from the difficulty of defining and adjusting to each party's allotted role within the democratic system, and from inter-party friction and bickering. The deficiencies in the present constitutional system have made it even more difficult for political parties to extricate themselves from a vicious struggle.
