2005年3月14日，中共第十屆全國人大第三次會議通過了「反分裂國家法」，國家主席胡錦濤並於當日公佈施行，頓時升高了台海關係的緊張；兩岸關係再度因為此法的制訂而有了新的詮釋與互動規則。「反分裂國家法」最初是以「國家統一法」為思考來醞釀的，從1999年前總統李登輝提出「兩國論」之後，中共的對台工作就始終有學者或是部分技術官僚建議制訂「國家統一法」加以因應，但並沒有立即獲得中共高層的同意。2000年陳水扁當選總統，持續的在兩岸關係上將台灣在統獨光譜上往台獨的方向推進，引起中共對台工作的焦慮。2004年當陳水扁再度連任時，面對這樣的政治局勢，北京對於制訂法律以法律作為統一綱領的作為開始認真思考。 反分裂法在諸多考量下通過，政治影響大於實質影響，兩岸關係也受到此法的公佈而有了新的互動邏輯。反分裂法的制訂，亦嚴重的影響兩岸之關係及台灣人民之情感，勢將波及兩岸之軍事及政策基調，這對兩岸人民之將來，顯然帶來不可預知之變數。 透過對於反分裂法的的制訂因素由來及條文內容解讀，進而分析「反分裂國家法」通過後對美、「中」、台三方之互動及影響，兼論台灣所可能產生的因應之道。 March 14,2005 the 3rd Whole nation congress conference passed anti-secession law which was also implemented by Chinese premier Hu Jin-tao in the meanwhile. Therefore, tension between cross-strait escalated suddenly and bilateral relation has come to a new interpretation and interactive rules. In the beginning, anti-secession law was the initiation of The law of National unification. After former president Li Deng-hui who brought forth the concept of Two-country theory in 1999,many bureaucrats as well as scholars have been suggested enacting The law of National unification as the basic guideline toward Taiwan, however, this offer has been not consented by the high level officials of the Beijing authorities immediately. In year 2000, Chen shui-bian was the President elect who has been pushing the status quo of Taiwan toward independence that has aroused the anxiety of PRC government with regard to the stance toward Taiwan. When president Chen was reelected in 2004,the Beijing authorities started to consider to enact a unification guideline to respond the situation. With many consideration the anti-secession law was passed. The influence from politics is beyond the essence. Thus cross-strait relation is entering a new stage and having a new mode of mutual interaction due to the enforcement of the law. The enactment of anti-secession law has affected bilateral relation and the emotions of people from both countries which would definitely make a great impact the fundamental of military policy between two countries. This will bring unexpected factors to the future of people in Taiwan and China. By analyzing the background of enacting anti-secession law and interpretation of relevant articles, we can further assess the triangular relation as well as impact between US.、China and Taiwan and how Taiwan could respond to possible influences.
