中文摘要：

以往的研究表明中国上市公司具备会计稳健性：较于好消息而言，上市公司更及时与充分的确认坏消息。但是我们发现这种稳健性是由于亏损公司在“洗大澡”造成的。我们运用4个稳健性指标进行检验，当没有控制亏损公司时，资料显示了一些稳健性的特征，但当控制了亏损公司后，会计盈余并没有表现出稳健性，而亏损公司却显示出了稳健性的特征。

英文摘要：

Empirical evidence has shown that there is accounting conservatism in mainland China： the earnings of listed companies reflect bad news more quickly than good news. Because of the ST and delisting requirements in mainland China, loss companies have strong incentives to take a big bath, which leads to bad news being reflected more quickly than good news in accounting earnings. Using four variables to measure conservatism, we find that its presence in the full sample results from the big bath behavior of loss companies.
