一個中國的問題，在在牽動著臺灣內部有關統獨的政治分歧，亦使兩岸關係僵滯不前，國際社會為之困惑。儘管我國屢屢在一個中國的問題上嘗試有所突破 ，以凸顯臺灣的主體性和兩岸的對等性，但〈中華民國憲法增修條文〉以「國家統一前」對兩岸關係現狀的自我界定，以及各方依此所展開的對於一個中國的詮釋，卻反而成為我國揚棄一個中國的主要障礙。本文乃試圖解構〈中華民國憲法〉及其修憲實踐所形成的兩岸關係定位，而以國民主權原理支撐事實主權，在事實主權基礎上證成特殊兩國論，復建議以法理主權和事實主權分別表述的方式來面對〈憲法〉存在一個中國架構的現實。

The one-China issue extensively influences Taiwan’s internal political struggles especially on that of independence or unification. It also holds back the development of the cross-strait relations and causes confusion to international community. Taiwan has been continuously trying to break through the siege of the one-China premise to emphasize its own subjectivity and its equality to Mainland China. Unfortunately, according to the Amendment to the Republic of China Constitution, it defines Taiwan’s present state as “prior to unification”. Along with separate interpretations of the one-China premise in all aspects, they become a primary barrier for Taiwan to discard China. This article intends to deconstruct the positioning of the cross-strait relations effectuated by the constitution and its amendment practice. It uses the people’s sovereignty theory to prop up the real sovereignty discourse, and consequently justify the special two-nation theory on the ground of real sovereignty. At last, it suggests the strategy of interpreting the legal and real sovereignty respectively to deal with the one-China constitutional framework.
