加害给付：当代合同义务群扩张视阈下的立法思考

在当代合同义务群扩张的视阈下,把加害给付概念和履行利益、固有利益关联起来,提出典型加害给付和非典型加害给付的新界定。把非典型加害给付理解为广义的附随义务,就能把《合同法》中的先合同义务、后合同义务概念和合同履行中的附随义务概念进行同类合并。其结果就是把《合同法》第42条、第43条（先合同义务）、第60条（履行过程中债务人的附随义务,即狭义的附随义务）、第92条（后合同义务）归并到关于＂诚实信用原则＂的＂一般规定＂之中。

On the Legislation of Injuring Performance：from the Perspective of the Contemporary Expansion of Contractual Obligations

From the perspective of the contemporary expansion of contractual obligations,this essay argues that we should relate the concept of injuring performance to performing interest and inherent interest,and makes a distinction between the typical and atypical injuring performance.If we regard the atypical injuring performance as ancillary obligation in a broader sense,then concepts of the pre-contract obligation,the post-obligation and the ancillary obligation in our country＇s ＂Law of contract＂ could be merged together,with the result that Article 42,Article 43（which concern the pre-contract obligation）,Article 60（which concerns the ancillary obligation fulfilled by the debtor in the course of performance）,and Article 92（which concerns the post-contract obligation） could all be amalgamated into general provisions of the principle of good faith.
