本文考察了中国2007年会计准则变动后，会计盈余在债务合约中的作用是否发生变化。研究发现，2007年执行新会计准则后，会计盈余对银行贷款的解释力显著降低；受准则变动影响程度较大的公司，会计盈余对银行贷款解释力的下降程度更大；国有控股和非国有控股公司的会计盈余与新增贷款的敏感性均显著下降，但相较于国有控股公司，非国有控股公司的下降程度更大。本文的研究表明，执行新会计准则后，会计盈余在债务合约中的作用显著下降。

英文摘要：

This paper investigates whether the usefulness of accounting profitability in debt contracts changes after the adoption of the new Chinese accounting standards （＂NCAS＂） in 2007. We find that the sensitivity of new debts to accounting profitability declines after the adoption and that firms are heavily influenced by the adoption of the new accounting standards and experience a more significant decrease in sensitivity. Moreover, such a decrease in sensitivity is more pronounced for non-state-owned companies than for state-owned companies. Overall, our results indicate that the usefulness of accounting profitability decreases after the adoption of the new accounting standards.
