信贷周期理论研究综述

Review on Credit Cycle Theory Research

信贷周期是银行在内生和外生的机制或条件下行为集合所形成的一种信贷紧缩和信贷扩张的交替往复的现象。国外学术界对于信贷周期理论的探讨,可以分为三个角度:一是基于信息经济学理论,从信贷市场的不完全性和信息不对称角度阐述了经济波动的信贷观点;二是从银行信贷行为的角度,认为银行的行为具有内在的顺周期性,从而加剧了经济的波动;三是从银行业风险管理和监管的角度考察。

credit cycle is a phenomenon in which credit contraction and credit expansion alternately take place as a result of the actions taken by the bank under the endogenous and exogenous mechanisms and conditions. Views about credit cycle theory from overseas academia can be approximately divided into three categories： first of all, based on information economies, credit explanation of economic fluctuation is formulated in the aspects of imperfection of credit market and asymmetry of information. Second, from the＇standpoint of bank, the behaviors of bank are supposed to be intrinsically procyelieal, which exacerbate the economic fluctuations. Third, credit cycle is studied at the angel of banking risk management and regulation.
