资产减值准备与公司盈余管理的实证分析

Asset value decrease prepare and company surplus management's demonstration analysis

本文以新《资产减值准则》为基础,采用多元回归模型,对我国上市公司资产减值准备与盈余管理之间的关系进行了实证分析。研究结果发现:计提资产减值准备是亏损公司操纵利润的一个重要手段;减值前亏损并且无法达到盈利的公司会以计提资产减值进行"大洗澡"为下一年盈利做准备;利润平滑动机的公司进行资产减值转回的可能性小于其他公司;微利公司倾向于计提大量的减值准备;2006～2007年,上市公司并没有加大对流动资产减值准备的计提和长期资产减值准备的转回。另外,文章还根据实证提出了建议。
