本文從問題意識的產生與演變，到確立研究動機與目的，以及從理解理論的內容，再到後冷戰台海局勢和美國在其中扮演角色的整體認識，故設定了如下的預期研究成果： 第一，界定後冷戰時期美國單極霸權的國際結構，其對台海兩岸局勢的制約及影響，特別是霸權穩定論的學理在美中台三邊互動關係之運用。 第二，界定自1993年至2000年柯林頓總統執政以來，美中台雙邊關係的發 展與變遷，以及美國在台海的政治、軍事、經貿關係上的互動，描繪出輪廓與特徵，並釐清美國在整個台海關係所扮演的角色、台灣和中共所受到的影響，並找出三邊互動模式。 第三，透過本文的研究結論來解釋美國對台海兩岸政策的基本主張與利益所 在，以比較的方式分析美國對於台灣以及中共政策的相同、差異與關聯性，對未來可能的發展做出若干的預測。

2000年3月18日，民進黨籍的總統候選人陳水扁意外勝出，當選中華民國第十任總統，締造台灣歷史上第一次的政黨輪替；2004年陳水扁再接再勵禪連執政。在陳水扁執政的八年期間，對兩岸政策接連出招，先是認為「九二共識」是「沒有共識的共識」，而以「九二精神」代之，然後拋出「一邊一國論」、終止「國統會」與「國統綱領」、「四要一沒有」及以台灣名義加入聯合國等言論或政策，其間中國大陸於2005年3月通過「反分裂國家法」，因此兩岸關係一直處於起伏不定與風波不斷的狀態。本文係以立法院公報為研究主體，針對民進黨政府於此期間的兩岸政策作探討，主要著重在政治與經貿方面，研究重點為民進黨執政的特色、政治理念、兩岸經貿政策，而與國民黨主政時期相較有何延續與變遷之處，及其面對全球化趨勢採取何種的思維與作為，從立法院公報的角度觀察民進黨執政八年兩岸相關政策的變遷。 關鍵詞：兩岸關係、兩岸政策、立法院公報、四不一沒有、九二共識、一邊一國 / On March 18, 2000, DPP presidential candidate Chen Shui-bian unexpectedly won the election to become the 10th president of the Republic of China. The result has made the history of the “party alternation in power” for the first time in Taiwan. On March 20, 2004, Chen Shui-bian once again was elected president for a second term. In the eight years of his rule, President Chen Shui-bian has made a serial moves on the cross-strait policy. Firstly, he alleged that the "92 consensus" is "Agree to Disagree " and replaced with the "92 spirit". After that he brought up “ one side one country,’’ abolishing “National Unification Council or the Guidelines for National Unification,” the “ four imperatives and one non-issue” policy, and joining the United Nations under the name of "Taiwan”. During that period, the passage of the "anti-secession law" in March 2005 created more tension on the already stressful relationship across the Taiwan Strait. This thesis is to research the Legislative Yuan Gazettes, aimed at the cross-strait policy taken by DPP government, and the main focus is on the aspects of political economy and trade. The main point is to analyze the characteristics, political beliefs, and the cross strait economy and trade policies of the ruling DPP government and to compare the continuances and changes to the KMT ruling era, as well as to review DPP’s thinking and action in coping with globalization. From the Legislative Yuan Gazettes’ angle, we could observe a different aspect of cross-strait policies taken by DPP in the eight years in power.
