摘 要 「世界貿易組織」（World Trade Organization，以下簡稱WTO）爭端解決下之貿易制裁，對於確保其任務之達成，扮演著十分重要的角色。惟自WTO成立後至今的數年間，所出現之「爭端解決機構」（The Dispute Settlement Body）授權貿易制裁之實例，透露了本機制之引發之問題，例如除了被制裁國強力反彈外，採取制裁措施之國自身也倍嚐其苦。針對上述問題，不論是學界或WTO會員國均有一些檢討改革的方案。 上述改革方案包括倡議以其他手段完全取代現行「爭端解決程序與規則瞭解書」（Understanding on Rules and Procedures Governing the Settlement of Disputes，以下簡稱DSU）之貿易制裁者，經過本文之分析，發現此等手段縱然取代DSU之貿易制裁，仍無法解決問題，蓋彼等或不具可行性、或有強制執行之困難。 鑑於貿易制裁對WTO規範遵循之確保，目前無可取代，故本文肯定其繼續存在之必要，同時強調貿易制裁之法制化並無礙WTO協定整體架構之邏輯一貫性。此外，法制化的結果，不但可確保貿易制裁受到監督，降低濫用的空間，更可藉由內建之定期檢討與修正，促使授權貿易制裁得以持續獲得改善，將負面影響降到最低。 / The authorization of trade sanction, which secures the objectives of the World Trade Organization (hereinafter the “WTO”) to be achieved, plays a very important role in WTO dispute settlement mechanism. However, since the establishment of the WTO, the DSB authorization of trade sanctions in some cases has revealed some problems. In some instances, the exercise of the trade sanctions triggers counter-measures of the respondent member, while in others, the complaint member also suffers for the trade sanction it imposes as authorized. In response to the aforementioned problems, commentators as well as WTO members have proposed some ideas of reform. The reform proposals include replacing the WTO trade sanctions with alternative measures. Nevertheless, after careful analyses of these proposals for alternatives, it is found in this thesis that the replacement of the WTO trade sanctions cannot resolve the aforementioned problems, in the sense that those alternatives suggested are not feasible or lack of ways to enforce them. In light of the fact that currently no feasible alternative can have the function as trade sanction has in assuring the compliance of the WTO rules, this thesis argues that it needs to be preserved. Besides, this thesis believes that it does not cause any conflict in the current WTO legal framework. To preserve it under the WTO framework, the abuse can be avoided through the surveillance of the DSB. Moreover, the built-in review mechanism, which will continue reform trade sanction measures, can minimize their negative effects.
