本文之目的係由本國航商之觀點探討其選擇本國航籍或權宜船籍之決策行為，同時以二元羅吉特模式實證分析航商在選擇本國船籍或權宜船籍偏好的重要決策因素。研究結果顯示船員成本、船體險、船舶維修費用對航商選擇本船籍或權宜船籍具有顯著影響力。船舶大小對權宜船籍之選擇具有影響性，且船舶愈大選擇權宜船籍的效用愈低。此外航商所屬船舶若經營區域為大陸、船舶為經營遠洋航線之貨櫃船者，其選擇權宜船籍的意願會比較高。在本文所假設的四種情境下，以降低國籍船舶船成本對降低權宜船籍之選擇機率影響最大。

This paper investigates the registration decision of choosing national flag or flag of convenience (FOC) in the viewpoints of shipowers in Taiwan. A binary logit model is applied to analyze the important factors that influence the registration decisions. An empirical analysis based on a binary logit model about the shipowners’ choosing flags is conducted to demonstrate the conception developed in this paper. The results show that the registration decision is highly affected by the cost of seafarers, Hull & Machinery Insurance as well as maintenance and repair costs. Ship size also affects the registration decision, especially the larger the ship, the lower the utility is conducted by FOC. There are also differences between the preferences of deploying mainland China, sailing international services as well as operating container. In addition, reducing 20% of cost of seafarers will most affect the choice of vessel registry in four assumed scenes.
