递延所得税确认与盈余管理相关性多角度研究

摘要

After the adoption of balance sheet liability method to cope with income tax, listed companies may take advantages of the provisions of deferred income tax assets and liabilities to manipulate the reported profits with the choice of accounting policies, the disposal of assets, the government subsidies, etc. This paper uses descriptive statistics and econometric models, such as basic Jones Model and ROE distribution method, to study the correlation between the reported deferred income tax and the existence/level of earning management and the earnings quality. We find that, there is a notable correlation between deferred income tax and earnings management, though it only reveals a small portion of the earnings management behavior, much less than the basic Jones Model does. In addition, the introduction of deferred income tax may weaken the sustainability and predictability of the enterprises’ reported earnings.%采用资产负债表债务法进行所得税核算后，上市公司可以通过选择会计政策、处置资产、提取及转回减值准备等方法控制递延所得税资产和递延所得税负债，从而达到调节所得税费用、操纵税后利润的目的。本文综合运用应计利润分离法、盈余分布检测法等成熟计量模型及描述性统计分析，研究了资产负债表债务法下确认的递延所得税及其变化对盈余管理行为存在性、盈余管理程度和盈余质量的影响。本文研究结果表明：以递延所得税为基础衡量的财税差异与企业的盈余管理行为具有显著相关性，但从整体上看该方法所能揭示的盈余管理程度有限，远不如传统的应计利润分离法。此外，进行递延所得税确认可能会削弱企业报告盈余的可持续性和可预测性。
