论《国际商事合同通则》对长期合同的调整

The Adjustment of Long-term Contracts in the UNIDROIT Principles of International Commercial Contracts

由于长期性、关系性和不完全性等特征,长期合同在适用一般合同法时会产生诸多困难。为此,罗马国际统一私法协会推出了《国际商事合同通则2016》,对长期合同的概念进行了界定,并在诚信谈判、开放性条款、非固定条款、当事人之间的合作、不可抗力、无固定期限合同终止后的恢复原状、后合同义务等方面作了特别规定,从而对长期合同的立法调整产生了积极的影响。为避免直接适用于长期合同所产生的不合理结果,我国《合同法》应借鉴《国际商事合同通则2016》的相关规定,加入调整长期合同的特别条款。

Attributing to the long duration,the relational nature and the open terms,long-term contracts differ from standard contracts.There are many issues particularly relevant in the context of long-term contracts that the general contract law does not address.Accordingly,the 2016 edition of the UNIDROIT Principles of International Commercial Contracts defines the notion of“long-term contracts”and contains a number of special provisions,such as negotiation,open terms,evolving terms,co-operation,supervening events,restitution and post-contractual obligations,which takes into account the special need of long-term contracts.It is suggested that the principles should be a model for Chinese legislature to amend Contract Law and provide adequate solutions for long-term contracts.
