立法院於民國九十二年七月十日三讀通過「自由貿易港區設置管理條例」，未來可在機場港口或鄰近地區設立境內關外的自由貿易港區，為我國企業界發展全球運籌管理創造優勢。自由貿易港區乃劃設特定區域集商業貿易、製造加工與科技開發於一體，作為開放度最高之經濟區，並將其視為境外之地，以特別立法排除國內法令之適用，尤其是關務行政及對課稅領域防線之調整，賦予高儲運作業效率及深層次產製加值等功能，以滿足貨品時效性及國際供應鏈之各種需求。本文探討鄰近我國之新加坡與香港之自由貿易港區通關制度，並依我國「自由貿易港區貨物通關管理辦法」之規定分析我國自由貿易港區之貨物通關制度。研究發現我國貨物進出自由貿易港區之規定，似仍存有限制貨物流通與海關管制之問題，並無法完全符合自由貿易港區設置管理條例中貨物自由流通之精神。本文最後提出結論與建議以供參考。
