Abstract: Using the signature data of three auditors,this paper examines the economic consequences of the signatures of three auditors from the perspective of enterprise violations.It is found that the signatures of three auditors significantly suppressed corporate violations,and the above results are still valid after controlling possible endogenous problems.The inhibitory effect of the signatures of the three auditors on enterprise violations is more significant in the enterprises with lower auditor industry exper-tise and higher agency costs,but there is no significant difference in the enterprises with different pro-perty rights.The function path test finds that the signatures of the three auditors suppress the violations of the enterprise by improving the quality of internal control.The economic consequence test finds that the signatures of the three auditors suppress the violation of the enterprise,but increase the audit cost in the future period.The research conclusion expands the research perspective of auditor behavior characteristics,contributes to a comprehensive understanding of the economic consequences of the signature of the three auditors,and also provides a new idea and reference for how to effectively restrain enterprise violations.

Key words: signatures of three auditors, enterprise violations, auditor industry expertise, agency cost, nature of property rights
