台灣四面環海，且與鄰國相距不遠，使得台灣專屬經濟區和大陸礁層多與他國重疊，導致海域爭端迭起，因此與鄰國之海洋劃界乃成重要課題。特別是台灣北方之東海海域，此海域向爲台灣之傳統漁場，但現爲台、日、中等國之重疊專屬經濟區；另一方面，東海大陸礁層富藏包括石油內之各種礦產，其中尤以中國在東海開發春曉油田且已量產，引起日本的抗議，成爲相鄰各國爭端之來源。因此，東海專屬經濟區與大陸礁層之劃界問題，誠爲當務之急矣！然而，由於台灣的國際地位特殊，國家定位不明，加以因中國之打壓，致遭國際組織排擠，在國際上難以發聲，令人擔憂。本文提出台灣之國際法律地位與海洋劃界之關係，希能引起政府與學者之探討，以維護台灣之海洋權利並進而避免台日海域爭端之產生，並希望從海域劃界之探討，能對台灣之國際法律地位有所助益。

Taiwan, surrounded by seas and being close to neighboring countries, makes its exclusive economic zone (EEZ) and continental shelf overlapped with the others. As a result, maritime disputes occur regularly. The Maritime Delimitation with neighboring countries, therefore, becomes an important subject. The maritime territory in East China Sea of Taiwan's north is the traditional fishing ground of Taiwan. At present, however, it has been overlapped by Taiwan, Japan and China's exclusive economic zones. In the other hand, there are vast amounts of minerals of various kinds in the continental shelves of East China Sea. China has started vastly exploited Chunxiao Oil Field there, which action has triggered Japan's protest and become the source of regional disputes. Thus it is urgent to settle the overlapping issues of EEZ and the delimitation of continental shelves. Because of Taiwan's special international status, combined with Beijing's pressure exerted around the world, Taiwan's status is uncertain. This has led to Taiwan's international space being squeezed and therefore hard to voice internationally. This paper seeks to elaborate the relationship between Taiwan's international legal status and the issue of maritime delimitation in the hopes of bringing about further discussions in scholar and government communities, protecting Taiwan's maritime rights from the occurrence Taiwan-Japan maritime disputes. In addition, we hope to contribute to the understanding of how to improve Taiwan's international legal status by examining maritime delimitation.
