我國民法債編制定公布於民國十八年十一月二十二日，自民國十九年五月五日生效施行，卻遲至民國八十八年四月二日始通過第一次修正案，經總統於同月二十一日公布，定於民國八十九年五月五日，即民法債編施行七千週年紀念日生效施行。 此次債編修正，就原六百十九個條文中，增修刪除二百三十四個條文，變動率幾達百分之三十八，其影響重大，無與倫比，更因其為跨世紀、入千禧之債法大修正，空前絕後，堪稱絕響。 本文就此次債編修正，溯其修正之經過，逐一檢視其修正條文，針對增訂八個新的有名契約予以進一步之評述，再對其修正結果條文依其性質及內容予以分類，並就其修正原則加以檢討，就其修正結果予以評述，最後就其修正條文之溯及生效，提出看法。 本文採用比較法的評論方法，其中牽涉諸多外國法例；且論文範圍廣泛，字數繁多，難免有無法深入問題核心、全部加以透徹研究之缺憾，然而，本文深盼提出諸多之問題，能夠引起廣泛之注意及討論，更加促進我國民法理論、實務及立法之發達及進步。
