内部控制信息披露质量与代理成本相关性研究--基于沪市2007年上市公司的经验数据

The Correlation Study on Internal Control Information Disclosure Quality and Agency Cost——An empirical research based on the listed companies of shanghai stock exchange in 2007

内部控制信息披露与公司治理密不可分、双向互动,并对公司代理成本有着直接的影响。本文以2008年6月财政部会同证监会、审计署、银监会、保监会颁发的《企业内部控制基本规范》为依据,设计了内部控制信息披露质量的评价指标体系,构建了内部控制信息披露指数(ICIDI),并对内部控制信息披露指数和代理成本之间的相关性进行了检验,结果表明内部控制信息披露指数与显性代理成本呈不显著负相关关系,与隐性代理成本变量总资产周转率呈显著正相关关系,与作为内部控制信息披露可观测的财务绩效变量ROA和ROE均显著正相关,即内部控制信息披露对显性代理成本抑制作用不显著,对隐性代理成本有明显抑制作用,对显性代理成本和隐性代理成本具有综合抑制作用。

Internal control information disclosure and corporation govemance are inseparable, and it directly influences corporation agency cost. This paper is based on the Enterprise Internal Control Basic Norms which is established and issued by The China Ministry of Finance, Securities Regulatory Commission, Auditing Administration, Bank Regulatory Commission, and Insurance Regulatory Commission in June 2008, we design the internal control information disclosure quality evaluation system and construct the Internal Control Information Disclosure Index （ICIDI）. We use multiple regression to examine the correlation between internal control information disclosure index and agency cost. The results show that internal control information disclosure is not significant negative correlated with explicit agency cost but significantly positive correlated with implicit agency cost which is measured by Asset Turnover Rate. ICIDI is also significantly positive correlated with ROA and ROE which measure the financial performance can be detected. Thus, internal control information disclosure is weekly helpful in inducing agency cost and can induce explicit agency cost. It has a combined restrain effect on explicit agency cost and implicit agency cost.
