The Analysis of Information Sharing Behavior among Banks and Credit System Construction

The decrease of asymmetry information between banks and borrowers benefits from information sharing mechanism among banks to a great degree. By analyzing motive mechanism of information sharing and cooperating through information sharing choice model, the paper believes that expectation value of information sharing is different to banks under current credit market structure, but compulsive information sharing by public organization is likely to produce two entirely different kinds of effects, one is dissociation, the other is participation. Therefore, the effective information sharing encouragement and restriction systems must be built up, which can push the banks to deepen information sharing to form relatively perfect social credit system, with assistance of public and private credit systems.
