「亞太自由貿易區」並非新的倡議或概念，但於亞太經合會「茂物目標」的第一個目標年（2010）即將屆至之此時，卻有愈來愈多的因素利其發展，而使之具有新的研究價值。2009 年亞太經合會的領袖宣言已明白要求部長及資深官員們於2010 年提出有關達成「亞太自由貿易區」之各種可能路徑的研究成果報告，而在日本之後於2011 年接辦亞太經合會年會的美國，更於歐巴馬政權上台後宣布繼續參與「跨太平洋策略性經濟夥伴協定」之擴大談判，並宣示將以之做為美國未來貿易之模型，意謂著此具有「開放加入」條款之協定有可能成為未來「亞太自由貿易區」之基礎架構。本研究擬就上述協定條文進行法律分析，輔以亞太經合會多年累積發展出來的 「模範措施」，並比較與其他東亞經濟整合協定條文規定之異同，同時兼論對世貿組織協定相關條文之可能影響，最後並就臺灣加入「亞太自由貿易區」之法律可行性提出看法，以供政策參考。 The Free Trade Area of the Asia-Pacific (FTAAP) is not a new proposal or idea, but there seems more and more elements that are good for its development emerging when the 1st target year of the Bogor Goals (year 2010) is approaching. The new momentum merits study. The APEC Leaders’ Statement of 2009 in fact already instructed Ministers and Officials to update Leaders in 2010 the progress on the outcome of the exploration of a range of possible pathways to achieve FTAAP. The United States, which is going to host the 2011 APEC meetings after Japan, further announced that the Obama Administration is going to continue the participation in the expansion negotiation of the Trans-Pacific Strategic Economic Partnership Agreement (TPP), which is also going to serve as a model for the future of American trade according to the new US Trade Representative. It means that the TPP with an “open accession” clause may become a building block for the future FTAAP. This Study from a legal perspective, analyzes the provisions of the TPP as well as the “Model Measures” developed through years by APEC on various RTAs/FTAs, and compares them with the provisions of the other East Asia RTAs/FTAs, such as ASEAN + N. In addition, the Study will explore their possible relation with the provisions of the WTO Agreement. In order to provide policy consideration, the Study will also discuss the legal feasibility of Taiwan’s participation in the future FTAAP.
