摘要
大陆法系的学者普遍认为债的发生原因有四种，即合同、侵权、无因管理和不当得利。其中前两个原因是债发生的主要原因。也是比较普遍的两个原因。在我国新的《合同法》颁布以后，有关合同方面的债主要由《合同法》来调整，而侵权之债目前还是由《民法通则》来调整，随着民法典的制订被提上日程、侵权法也看到了独立的曙光。
Scholars in the civil law countries generally consider that： obligations arise out of contract, tort, voluntary service and unjust enrichment. The first two causes are the two principal and prevailing causes for obligations. Since the promulgation of the Contract Law of China recently, theobligations in contract have been regulated mainly by this law, while the obligations in tort are still subject to the regulation by the General Civil Law.
