缔约过失责任是指在合同订立过程中,缔约当事人因违反基于诚实信用原则产生的先合同义务而给对方当事人造成损害时所应承担的民事责任。随着市场经济的繁荣,订约方式的多样化,许多纠纷发生在缔约阶段。无契约则无责任,这种看似对契约自由的绝对尊重,实质上却使契约法背离了实质的、真正意义上的自由。为此,本文在借鉴前人研究成果的基础上试图对缔约过失责任制度的历史沿革、概念、请求权基础等问题进行初步的探讨与分析,以期对完善我国缔约过失责任能有所帮助。 Liability for contracting negligence refers to the civil liability that the contracting parties should bear in the process of contractual damage caused to contracting parties for breach of the precontractual obligations arising out of the principle of good faith. With the prosperity of the market economy and the diversification of contractual arrangements, many disputes have taken place in the contracting phase. There is no liability without a contract. This seemingly absolute respect for the freedom of contract essentially derogates the contractual law from substantive and real freedom. Therefore, based on the research results of predecessors, this article tries to make a preliminary study and analysis of the historical evolution, concepts and the basis of the right of request for fault negligence in the treaty so as to be helpful to improve the fault liability of contracting in our country.
