基于SEM的公司治理对会计信息可比性的影响研究

Study on the Impact of Corporate Governance on the Accounting Information Comparability Based on Structural Equation Modeling

本文借助于杜邦分析体系,给出了一种新的不依赖于市场有效性的直接测定基于公司层面的会计信息可比性的方法,并采用结构方程模型对公司治理结构与会计信息可比性两者之间的关系进行了深入探讨。研究发现:公司治理对会计信息可比性产生正向效应,说明公司治理结构越完善有效,会计信息可比性越强;从路径系数上来看,公司外部治理对会计信息可比性的影响较大;公司外部治理也直接影响着内部治理,并且这种影响是正向的。

With the help of DuPont analysis system,this paper gives a new method which measures directly the accounting information comparability based on the company level and does not depend on the efficient market.And using the Structural Equation Model,this paper discusses deeply the relation of corporate governance structure and accounting information comparability.The study finds that:Corporate governance structure can have a positive effect on accounting information comparability,which illustrates that governance structure is more perfect and effective,accounting information comparability can be stronger.From the path coefficients,the influence of corporate external governance to accounting information comparability is larger than the internal governance.The corporate external governance has a direct impact on the internal governance and this effect is positive.
