南海諸島不僅擁有豐富的資源，更處於重要的戰略位置，目前共有六個主要 聲索國主張對南海諸島擁有領土主權，分別是中華民國、中國大陸、菲律賓、越 南、馬來西亞與汶萊，美國雖然不是聲索國，但基於維護其在南海的重要利益， 所以也涉入南海的紛爭，這使得南海的局勢更加複雜。 我國、中國大陸與菲律賓皆主張對南海諸島中的黃岩島享有主權，2012 年中 國大陸與菲律賓之間爆發了黃岩島事件，更使南海的緊張情勢升至最高，於是菲 律賓便訴諸於國際仲裁法庭，仲裁庭並未就主權的歸屬作出判決，而是對《聯合 國海洋法公約》的解釋問題作出裁判，但南海諸島的主權爭奪仍就方興未艾。 有關領土主權的取得，1928 年帕瑪斯島案的仲裁法官指出「持續與和平展示 領土主權幾乎就等於主權本身」，而這便是「有效統治」的核心，本文因此挑選 四個與有效統治高度相關的國際司法機構判決來作分析，並參酌相關國際法的原 則與發展，以歸納出「有效統治」的構成要件、衡量指標與法律效果，並利用這 個歸納結果來對我國、中國大陸與菲律賓在黃岩島領土主權的爭端進行分析，判 斷結果雖是我國擁有黃岩島的領土主權，但由於我國目前沒有實質控制該島礁， 因此本文也試著提出具體建議來強化我國的主張。 / The islands of the South China Sea (SCS) not only have an abundance of resources, but also are strategically located. There are six major countries that claim territorial sovereignty over the islands, including the R.O.C. (Taiwan), Mainland China, the Philippines, Vietnam, Malaysia and Brunei. Although the U.S.A. is not one of the claimants, it is still involved in the SCS dispute because of its important interests in that region. Thus, the situation in the SCS has become more complicated. Taiwan, Mainland China, and the Philippines all claim to have sovereignty over Huangyen Island in the SCS. The “Huangyen Island Incident” between Mainland China and the Philippines broke out in 2012, bringing tensions in SCS to a height. The Philippines thus resorted to the international Arbitral Tribunal. The tribunal didn’t make a ruling on sovereignty, but it made a ruling regarding the explanatory question of the United Nations Convention on the Law of the Sea. However, the tit-for-tat over the sovereignty of the SCS islands continues. Regarding the acquisition of territorial sovereignty, the arbitrator of the 1928 Palmas case indicated that, “the continuous and peaceful display of territorial sovereignty is as good as a title.” This is the exact the core of effectivités. To conclude the components, indicators and the legal effect of the effectivités, the thesis thus considered related principals and development of international law, and selected four rulings of international judicial bodies to analyze, as these four ruling are highly-relevant to effectivités. Furthermore, based on the results of the above analysis, this thesis also analyzes the territorial sovereignty dispute over Huangyen Island among Taiwan, Mainland China, and the Philippines. The analysis concludes that Taiwan has the territorial sovereignty over Huangyen Island. Given the fact that Taiwan doesn't substantially control it, the thesis also tries to come up with advice to strengthen Taiwan’s claim.
