商业银行风险承担、融资约束与货币政策信贷渠道

Risk Taking、Financing Constraints of Commercial Bank and Credit Transmission Channel of Monetary Policy

本文从商业银行的风险承担角度,结合我国转轨经济背景,检验商业银行风险承担水平以及所面临的融资约束对银行贷款供给的影响。研究发现,我国商业银行的风险承担水平与规模存在显著的负相关关系,且这种负相关关系在货币政策紧缩期间进一步加强;同时,由于中小规模银行的吸储能力较弱,面临的融资约束限制了中小规模银行在货币紧缩时期的风险承担水平,中等规模银行可以通过非存款融资缓解,但小规模银行存在融资硬约束。

In the context of transition economy, this paper study the effect of commercial bank＇ s risk taking willing and financ- ing constraints on the supply of bank credit from the perspective of commercial bank＇ s risk taking. The results of our study in- dicates that risk taking willing of commercial bank has significant negative correlation with the bank scale, and this negative correlation become stronger in the tight-money policy period. At the same time, the weak deposit-ftmding ability of middle and small size bank constraints their willing to taking risk in the tight-money policy period, the middle size bank can reduce the constraints from other funding approach, but the small bank has rigid financing constraints.
