摘要：

《民法典》颁布后，合同、侵权两编的界限有待澄清。我国学者主张将保护义务排他性地划入侵权 法，导致我国合同法救济范围收窄以及侵权法虚胖，在合同、侵权之间形成多层次竞合的复杂局面。从私法史 看，该观点实为潘德克顿法学既有路径的重现。其背离了罗马法上合同、侵权自由竞合，中间地带以合同法调 整为主，侵权法为辅的开放边界。现代德国法以附随义务学说实现了对潘德克顿法学的修补，向罗马法传统回 调。据此，我国 《民法典》应允许适度竞合的存在，但在交错区域应超越传统竞合理论，尽力统合违约及侵权 责任的构成要件，达成统一的法律评价结果。

Abstract: After the promulgation of China’s Civil Code，the boundary of contract and torts needs to be clarified.One popular view claims that the obligation of protection should be exclusively classified from contract into torts.But it causes the functional contraction of contract and the puffiness of torts as well as the multi-level competitions between them.From the perspective of the history of civil law，this opinion is the recurrence of the Pandectists，which departed from the open boundary in Roman law，in which contract and torts were allowed to compete freely，but the crossing area was mainly regulated by contract with the supplement of torts.But modern German law repaired the defects of Pandectists by developing the doctrine of accessory obligation and turned back to the Roman tradition.Accordingly，China’s Civil Code should allow the existence of moderate competition in the crossing area but go beyond the traditional theories by integrating the factors of contractual and tortious liability to reach a unified legal result.
