This research aims at studying legal dogmatics when the debtor's performance becomes impossible under the bilateral contract and not only the debtor but also the creditor is contribute to the impossibility to perform. The major findings of a comparative analysis of German law are summarized as follows. First, to make a precise reflection of a contribution ratio of each party in the legal effect, we need that a claim for counter-performance exists or a claim for damages is granted to the debtor in exchange for an extinction of a claim for counter-performance. Second, when the debtor's claim for counter-performance exists, we need to modify all of the creditor's remedies which extinguish a claim for counter-performance. Third, when a claim for damages is granted to the debtor, it matters if there is creditor's nonperformance. Fourth, when we make a modification of the legal effects, following 3 points mainly need to be considered. Respect for the value relevance between performance and counter-performance ; a precise reflection of a contribution ratio of each party in the legal effect ; consideration of the particularity arising in cases when counter-performance is nonmonetary debt.

这项研究旨在研究债务人在双边合同下变得不可能的债务绩效时，不仅债务人，而且债权人也有助于表现不可能。对德国法律比较分析的主要发现总结如下。首先，为了确切地反映各方在法律效力中的捐款比率，我们需要向债务人征收反绩效的索赔或赔偿索赔，以换取对反绩效索赔的灭绝。其次，当债务人对反绩效的索赔存在时，我们需要修改所有债权人的补救措施，以消除对反绩效的要求。第三，当向债务人征收损害赔偿索赔时，是否有债权人的不履行至关重要。第四，当我们对法律效果进行修改时，主要需要考虑3分。尊重绩效和反性能之间的价值相关性；在法律效力中对各方的贡献比率的精确反映；在反绩效的情况下，考虑到非货币债务而产生的特殊性。
