| 摘要: |
| 不当得利法始于罗马法，集大成于德国民法，旨在调整私法上无法律上原因的财产变动，涉及整个私法关系。中国台湾地区不当得利法继受于德国，其法释义学的建构亦主要依靠学说继受。在不当得利法的体系建构上，类型化区分非常关键。当前台湾地区通说采类型说，将不当得利区分为给付型不当得利和非给付型不当得利两大类型。前者旨在调整失败法律交易的财产变动、物权行为无因性理论，与市场私法自治密切相关。后者尤其是权益侵害型不当得利旨在强化对权益的保护，有较广阔的适用领域。通过比较法学说继受、本土判例积累以及学说发展深化，建构不当得利的理论体系并使之精细化，亦是大陆不当得利法发展的重要课题。 |

| Abstract: |
| The law of unjust enrichment, originated in Roman law and synthesized in German civil law, is designed to regulate property transfers in private law without a legal ground and involves the entire private legal relationships. The law of unjust enrichment in Taiwan region was inherited from German law, and the construction of its legal dogmatics also relies mainly on the reception of legal theories. In the construction of the legal system of unjust enrichment, the typological distinction is very crucial. Currently, the prevailing view in Taiwan region adopts the typology theory, which distinguishes two major types of unjust enrichment, namely, unjust enrichment based on performance and unjust enrichment not based on performance. The former, closely related to the autonomy of private law, is intended to regulate the property transfers in failed transactions and to adjust the theory of non-causality of ownership transfers. The latter, especially the unjust enrichment based on infringement, aims to strengthen the legal protection of rights and interests, and has a broader field of application. It is also an important issue for the development of unjust enrichment law in Mainland China that to construct and refine the theoretical system of unjust enrichment law through the reception of legal theories, the accumulation of local jurisprudence and the development of academic studies. |
