貿易法與競爭法間互動之爭議已存在多年，此爭議出現之原因大致上有四點，即1.規避內國競爭法規範之國際反競爭行為之出現，2.跨國企業因為面臨各國之多重或衝突競爭政策之負擔3.內國競爭法因管轄所致生之困頓4.國際貿易流通並未因邊境障礙之去除而如預期順利。 而競爭法與貿易法間除具備本質上之差異性外，事實上仍具有互補性，甚至在現今之GATT/WTO法律架構下，仍不難發現諸多與競爭有關之貿易規定。本文就貿易法與競爭法間互動之爭議，提出一項嶄新的解決方案，即自基本權保障之角度。作者就現今GATT/WTO之法律制度以及國際法之發展，以及歐洲經濟整合經驗之啟發，自國際經濟法律秩序中歸納出以法律一般原則為形式之實質法源，作為對於經濟基本權予以保障之實證法基礎。而此法律一般原則不但可作為國際競爭法與貿易法平衡點之基礎，更可作為思考諸多目前國際經濟法上爭議問題之起點。
