港口國管制(Port State Control簡稱PSC)係依據國際海事組織(IMO)、國際勞工組織(ILO)、國際海洋法公約(UNCLOS)及各國立法程序通過之國家法律等相關規定來執行檢查從外國進入的船舶；以漸次消除全球不合於公約規定之次標準船，期能確保海上航行安全，防止海水污染及提昇船員工作環境等訴求。 本文旨在對檢查程序之相關定義、港口國管制檢查程序與準則及執行檢查之明顯證據與東京備忘錄的組織與發展等作一概略探討，並建議我國應積極力行實踐東京備忘錄之港口國管制程序及其規定，以進入該組織，成為國際社會一員為目標。

　　　　　Port State Control (PSC) is based on regulations of International Standards such as International Maritime Organization (IMO), International Labor Organization (1LO), United Nations Convention on the Law of the Sea (UNCLOS) and domestic laws of the port states (such as our country) to inspect foreign country ships. The long term purposes of PSC are to gradually reduce ships that do not satisfy international requirements/standards for environmental protection, improvement of seafarers' working environment, and ensuring of safety of ships. This paper describes the key PSC issues, including terminologies, inspection procedures and regulations, clear evidence of deficiency, and Tokyo MOU. This paper also made suggestions to improve the PSC systems of our country to comply with PSC international standards.
