监管约束与商业银行同业资产稳健发展——基于15家上市银行的实证分析

Regulatory Constraints and the Interbank Asset Development: an Empirical Study based on 15 Listed Banks

本文在梳理资本充足性、资产质量、流动性等监管因素影响银行同业资产发展的理论基础上,对我国15家上市银行2010—2015年的相关数据进行了实证分析。实证结果表明:资本越充足、存贷比越高、资产质量越差、同业监管越宽松,商业银行同业资产的占比也越高;同时,由于在资产久期、资金盈余状况、经营战略和管理模式上的不同,大型银行和中小型银行在同业资产的运用上存在差异。在此基础上,本文提出了相关政策建议,以期进一步规范和促进银行同业业务健康稳健发展。

This paper shows that capital adequacy, asset quality and liquidity may have impacts on the interbank assets of commercial banks, which has been empirialcally tested by using the data of 15 listed banks from 2010-2016. We find that the ratio of interbank asset over the total asset is positively correlated with capital adequacy, deposit-loan ratio and slack regulations and negatively correlated with asset quality. In addition, the state of interbank assets of large banks and small-and medium- banks are different due to different asset duration, profitability, operating and management strategies. This paper then proposes some policy suggestions to regulate the interbank assets of commercial banks for healthy development.
