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。

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.
