非信贷业务与银行绩效

Research on Non-credit Business and Bank Performance

通过发展非信贷业务实施业务结构调整已经成为我国银行业的普遍做法。本文基于208家银行2008-2012年数据,从资产和收入两个角度分别考察了利率市场化背景下非信贷业务对银行盈利能力和风险的影响及其背后的影响机制。主要发现包括:(1)无论是从资产还是从收入角度来看,非信贷业务总体上都会降低银行的盈利能力并加大银行的风险,这一结论在控制了内生性之后仍然成立。(2)较高的存贷款利差是导致非信贷业务降低银行盈利能力的重要原因:存贷款利差越高,非信贷业务对银行盈利能力的负向作用越明显;随着存贷款利差的降低,非信贷业务对银行盈利能力的负向作用会减弱甚至出现逆转。(3)非信贷业务之所以会加大银行的经营风险,主要是由于非信贷业务本身较高的波动性所引起。本文的研究对于推动我国银行业的发展转型具有重要的参考价值。

Non-credit business has been a major measure for business restructuring in China＇s banking industry. Based on a data set of 208 banks, this paper investigates the effect of non-credit business on bank＇s profitability and risk and the mechanism from asset and income perspective, respectively. Major findings include： （1） non-credit business will reduce bank＇s profitability and increase bank＇s risk from both asset and income perspective, which still holds after controlling for endogeneity. （2） the high deposit-to-loan spreads is an important factor for why non-credit business reduces bank＇s prof- itability： the higher the deposit-to-loan spreads is, the more non-credit business will reduce bank＇s profitability. As the de- posit-to-loan spreads becomes lower, the negative effect of non-credit business on bank＇s profitability will be reduced or even reversed. （3） the reason why non-credit business increases bank＇s risk is the high volatility of non-credit business. This research has an important reference value for the development and transformation of China＇s banking industry.
