资产减值会计信息价值相关性:整体分析

Research on Value Relevance of Asset Write—offs/Write-Downs:Unitary Analysis

本文利用2001～2006年度的上市公司数据,以价值相关性作为判断资产减值会计信息质量的标准。通过实证分析显示,资产减值会计信息更多体现为损益表项目而非资产负债表项目。这表明,资产减值没有反映资产价值的真实减少,而沦为管理层操纵盈余的工具。本文还以深交所信息披露评级作为判断信息披露质量的标准,实证结果显示,信息披露评级的高低没有影响资产减值会计信息的价值相关性。

Based on the data of listed companies in China from 2001 to 2006, the paper analyzed the value relevance of accounting information of asset write-offs/write-downs utilizing empirical research method. Out empirical research provided evidence that the information of asset write-offs/write-downs in China is not value relevance and asset write-offs/write-downs turns into the tools for management to manipulate earnings. Besides, we also analyzed the relationship between value relevance of asset write-offs/writedowns and the rank of information disclosure of listed companies by stock exchange of Shenzhen, and we did not find any evidence supporting the viewpoint that the higher the rank the more value relevance of information of asset write-offs/write-downs.
