市场竞争度、非利息收入对银行收益的影响研究

The Study on the Impact of Market Competition Degree and Non-interest Income on Bank Returns

本文利用我国2005—2014年101家商业银行的非平衡面板数据,采用动态面板广义矩估计(GMM)方法,研究了市场竞争度、非利息收入对银行收益的影响。研究结果表明,总体上我国银行业市场竞争度与银行收益显著负相关。在我国银行业当前的竞争状况下,非利息收入与银行收益显著正相关。随着竞争度的逐步提高,非利息收入对于银行收益的边际影响越来越小。另外,对于不同类型的银行样本,非利息收入的影响并不一致。对于大型商业银行,手续费及佣金收入的增加显著提高了银行收益,其他非利息收入则没有显著影响;与之相反,对于中小型商业银行,其他非利息收入的增加显著提高了银行收益,但手续费及佣金收入则没有显著影响。最后,我们分析了出现这种差异的原因并提出了相关建议。

Based on 101 commercial banks＇ unbalanced panel data of our country during the periods of 2005-2014, and using the method of dynamic panel GMM estimation, this paper studies the impact of market competition degree and non-interest income on bank returns. The results show that the market competition of China＇s banking industry has a negative correlation with the bank returns generally. And under the current competition situation of China＇s banking industry, non-interest income has a positive correlation with bank returns. However, with the gradual increase of competition degree, the marginal effect of non-interest income on bank re- turns is getting smaller and smaller. In addition, for different types of bank samples, the impact is not consistent. For large commercial banks, the increase of net fees and commissions income significantly increases bank returns, but other non-interest income has no significant effect. In contrast, for medium and small commercial banks, the increase of other non-interest income significantly increases bank returns, but net fees and commissions income has no significant effect. Finally, we analyze the reasons for the differences and propose some related suggestions.
