【摘要】 财务会计的目标是为财务报告的使用者提供决策有用的财务信息,为了提供更为可靠、相关的财务信息,企业可以进行自发性会计政策变更。然而,由于利益的驱使,企业有时会通过合法而不合理的会计变更来满足自身的利益需求,特别是上市公司,利用会计变更进行利润操纵的情形尤为严重。因此,探究企业会计变更的动因,找出存在的问题根源、规范企业的会计行为具有重要的现实意义。自发性会计政策变更及高管变更是实证会计理论研究的核心内容之一,国外会计学界围绕上述问题进行了卓有成效的大量研究。但是这些研究在很大程度上忽略了转型经济国家的固有特征,因而不能达到解释转型经济国家会计实务的目的。正是在这样的背景下,本文着重研究了发生高管变动的上市公司在变动过程中否存在滥用会计变更的行为,旨在为规范上市公司管理层激励、完善上市公司治理结构和会计变更会计准则、加强证券市场外部监管提供有意义的参考。本文首先对会计选择和高管的概念进行了界定,并且分别从会计政策分类、会计政策选择的环境分析与高管概念、高管人员界定等概念进行了阐述,然后依次介绍了委托代理理论、激励理论、信息不对称、选择性不实财务披露与经济后果学说等相关理论,总结了高管人员的会计变更动机,接下来对我国高管变更与会计变更现状进行了初步描述,得出,由于我国外部监管和公司治理结构的逐步完善,公司对高管的更换越来越谨慎,会计变更的行为主要集中在会计估计变更。最后为了说明高管变更与会计变更之间的关系,本文引入线性回归模型分析,筛选出2007-2009年自发性会计变更的样本,然后把其划分为高管约束性更换与非约束性更换及高管未更换两个子样本,结合自发性会计变更的方向,进行实证之后得出高管变更同时伴随着利润操纵的事实。最后,总结出正是由于上市公司在内部管理机制和外部审计监控力度不够的缺陷下,才导致利用会计变更这一手段达到调节利润的目的。由此对我国上市公司治理机制的完善与会计选择提出建议,以使提供给财务报表使用者的财务信息更加相关、可靠。更多还原
