英文摘要：

Taking the companies with financial restatements as the sam- ple with low quality of accounting information, this paper investigates the relationship between the background characteristics of CFOs and the quality of accounting information. It finds that the financial expertise of CFOs, namely CFO is a CPA, is positively related to the quality of ac- counting informa-tion and the companies whose CFOs are female are more likely to get the good quality of accounting information. Furthermore, the fi- nancial expertise of CFOs is beneficial to the reduction in the occurrence probability and frequency of accounting errors. The conclusions affirm the role of CFOs in financial statement and provide evidence for correcting ac- counting information distortion.
