内部控制质量与银行风险承担——来自我国上市银行的经验证据

Internal Control Quality and Banks' Risk-taking——Evidence from Chinese listed banks

现有关于内部控制经济后果的研究主要沿袭美国会计领域"内部控制——会计信息环境——会计信息引发的经济后果"的研究范式,鲜有探讨其在经营管理活动中的直接作用。即使少数几篇文章略有涉及,但均将银行从其研究样本中剔除了。鉴于此,现有文献无法回答:对于风险管控尤为重要的银行,内部控制在其经营管理中到底发挥何种作用?为此,论文以2007~2014年我国16家上市银行为样本,探索性地从风险承担的视角对此进行实证检验。结果表明:高质量的内部控制可以有效降低银行的风险承担水平;进一步发现,该效应在国有控股银行、特许权价值更低的银行中更为明显。除理论贡献外,论文对于银行风险管控实务和银行业监管均具有重要启示意义。

Our existing literature on the economical consequences of internal control routinely follows the research paradigm adopted by accounting researchers in U.S.＂Internal control --Accounting information environment- -- Consequences derived from accounting information＂, while its direct roles in operation and management are highly unexplored. Although a few papers have involveddo it, they＇ve excluded banks from their samples. Consequently, it＇s unclear how internal control affects operation and management in banking industry that pays more attention on risk management. Sampling from the listed banks in China over a the period from 2007 to 2014, this study paper has investigated this issue from the perspective of risk-taking. Empirical results show that high- quality internal control can reduce banks＇ risk-taking, and this reduction effect of internal control on banks＇ risk- taking is more pronounced in stated-owned banks and the banks of lower charter value. Besides the theoretical contribution, our findings have material implication for banks＇ risk management and banking regulation.
