從2000年民進黨政府執政以來，兩岸關係出現巨大的變化，受到臺灣主體意識昂揚，以及民進黨政府偏向臺獨的政策主張刺激，中國與美國面對兩岸結構所可以接受的底線也被迫陸續表態。其中，中國更在2005年3月14日以制定《反分裂國家法》作為日後面對臺灣統獨問題的依據，而美國則受到中國在國際影響力持續上升的壓力下，在兩岸角力中也調整與中國的關係。在這個過程裡，臺灣因為選舉競爭而切割成泛藍與泛綠兩個政治意識的區塊，執政的民進黨在兩岸關係的議題方面，不僅要在推進臺灣主體意識上與中國競爭，也要在選舉時與泛藍競爭。中國制定的《反分裂國家法》，是對美、中、臺一個再一次角力的結點，其中對臺灣而言，這個結點更是具有雙重意義，因為互動的結果也會影響國內選民未來的投票傾向。本文認為，在《反分裂國家法》制定後，美中臺在兩岸問題上將進行一場新均衡的賽局，而這個賽局不僅影響兩岸關係，也會影響臺灣國內的政治競爭。

The Cross-Strait relations have changed a lot since 2000 when Democratic Progressive Party (DPP) won the presidential election. Beijing and Washington have to make their strategies more clear because Taipei is moving toward independence. Beijing made the Anti-Secession Law to avoid independence of Taiwan. During this time, Washington's position is closer to Beijing because of the rising of China. And Taiwan is spilt into two camps: the Pan­B1ueand the Pan-Green. DPP has to compete with the Pan-Blue in the national elections and with Beijing in the international arena about the issue of Taiwan's independence. The Anti-Secession Law will be a node in the triangle game among Taipei, Beijing, and Washington. It will also affect the voters' attitudes in Taiwan. The Anti-Secession Law will be a triangle game in two levels. Taipei, Beijing, and Washington have to structure a new equilibrium, and it will also affect the election campaign in Taiwan.
