论我国情势变更原则下再交涉义务的构建

再交涉义务是情势变更情形中,解决合同最终效力的前提性问题。纵向建立再交涉义务的内容体系,对于违反再交涉义务的情形,运用谱系化的分析方法,区分提出交涉方与响应方,适用不同的法律效果。本文针对我国理论界对再交涉义务研究的缺乏,通过分析国外关于再交涉义务的理论,提出了我国设立再交涉义务的理论构成：在情势变更原则下,把再交涉义务作为诉讼上行使变更和解除合同请求权的前置义务,第一重效果为再交涉义务的履行,第二重效果为合同的变更、解除以及损害赔偿,在违反再交涉义务时,产生第二重法律效果。

On the Construction of Re-negotiation Obligations under Changed Circumstances Principle in China

Re-negotiation obligation is the premise to resolve the ultimate effectiveness issue of contracts in changed circumstances.We should establish longitudinal content system of re-negotiation obligations;for the situation that re-negotiation obligation is breached,we should use spectrum analysis method to distinguish responder side and make representations for different legal effects.Aimed at the lack of the study of re-negotiate obligation in China＇s theoretical circle,this paper through analyzing the foreign theory of re-negotiation obligations,puts forward the construction of China＇s re-negotiation obligation theory ：under the changed circumstances principle,take the re-negotiate obligation as the pre-obligation of litigation when exercising the claim of the modification and rescission of contracts,the first effect is to perform the re-negotiation obligations,and the second one is the modification and rescission of contract and the compensation for damages, when the breach of re-negotiation obligations happens,the second effect will occur.
