合同法诚信原则之研究简

诚信原则作为民法的基本原则对于私法的发展起着举足轻重的作用，而合同法中的诚信原则更是以其诚实、善意、公正的理念受到了人们的推崇。根据合同成立的不同阶段，合同法中的诚信原则的具体内涵主要包括：一是磋商中的诚信，即在合同谈判过程中，双方当事人不得以恶意隐瞒、欺诈及胁迫等形式促使合同的成立；二是诚信履行。即双方当事人在合同履行阶段应当按照交易的本旨勤勉的履行合同，不得滥用权利，违反诚信、恶意履行；三是合同终止后的诚信义务，通常表现为合同终止后的通知、协助及保密的义务。在以合意为中心构建而成的古典契约法理论和绝对契约自由遭到抨击之时．诚信原则犹如普罗米修斯之火给合同法带来了新生，以诚信原则为基础的关系契约论的兴起，限制了绝对的契约自由，将传统的“铁面无私”的合同法重塑为富有“人类真情实感”的合同法。

Study on Good Faith Principle in Contract Law

Good faith principle plays an important role in the development of private law as the fundamental principle of civil law, and the principle of good faith with the concept of honesty, kindness, justice in contract law is revered by the people. According to the different stages of the contract, the good faith principle in the contract law has different connotations, mainly including： the first one is to negotiate in good faith, namely, in the process of contract negotiations, the parties shall not maliciously conceal information or use fraud and intimidation methods to prompt the establishment of the contract. The second is to perform contract honestly and diligently between the parties in accordance with the tenet of the contract; they shall not abuse their rights, violate the good faith, or maliciously perform the contract. The third is the good faith obligation after the termination of the contract, which is often manifested as the obligation of notification, assistance and confidentiality. When the classical theory with the consensus as the focus and the absolute freedom of contract were criticized, the good faith principle, like the fire of Prometheus, brought new hope to the contract law. The relational contract theory on the basis of the principle of good faith limits the absolute freedom of contract and transforms the traditional ＂untouchables＂ contract law into the rich ＂human feelings＂ of contract law.
