摘要
如何配置信贷资源,是集中于某几个行业和一些大客户还是分散配置,对商业银行的风险会造成重大影响,也成为银行经营的一个两难选择。在中国经济进入新常态,不良频发的当下,商业银行对于集中度的把控将对资产质量水平造成重大影响。本文基于中国16家A股上市商业银行2007年到2014年的半年度数据,使用固定效应模型检验了信贷集中度对商业银行资产质量水平的影响。主要结论是:行业累积集中度提升会增加商业银行的风险,客户累积集中度提升会降低商业银行的风险。在经济上行周期,对于大型国有银行,行业集中度对银行风险的正向影响被显著加强。但经济周期和商业银行所有权性质差异并没有影响客户集中度对资产质量的影响。
How to allocate credit resources and whether to concentrate or diversify these resources have an important impact on commercial banks＇ risk and turn out to be a trade-off for banks. As Chinese economy goes into new normal stage and non-performing loans grow up dramatically these days, asset quality will be deeply influenced by concentration control. Based on the half-year data of 16 commercial banks on A share market during the period between 2007 and 2014, this paper employs fixed-effect model to justify how credit concentration affects commercial banks＇ asset quality. The main results are as followed： higher industry accumulated concentration leads to higher bank risk. During the upturn of business cycle, this effect is strengthened for state-owned banks. However, higher client accumulated concentration leads to lower bank risk. The busi- ness cycle and ownership structure have little influence on this effect.
