Microeconomic Foundation of the Credit System:An Analysis on Credit Behavior

信用制度的微观基础是经济活动主体的信用行为。由信用行为而产生的信用关系可归结为三种基本形式:单方面的信用关系、双方相互信用关系和中介的信用关系。对这三种形式下的信用行为的分析表明,竞争性市场并不会自发地形成可靠的信用关系;每一种信用关系都需要一个完善的社会信用制度来支撑。The microeconomic foundation of the credit system is the individual credit behaviors while the behaviors give rise to credit relations.There are three types of fundamental forms of such credit relations, i.e., unilateral credit relations, mutual credit relations, and mediated credit relations.The analysis of this paper on these forms concludes that the competitive market can not automatically or spontaeously result in reliable credit relations, and that every form of credit relations has to be supported by a solid foundation of social credit system
