Based on the listed companies with internal control material weakness（ICMW）from 2012 to 2015，this paper attempts to investigate the effect of management cognitive bias on the behavior choice in internal control information disclosure using a local observation double variable probitmodel.The results show that the higher of management overconfidence，the more likely the company will reduce the identification of internal control weakness severity，leading to the behavior choice in internal control information disclosure.The more myopic the management is，the more likely the company is to conceal the identified internal control material weakness，leading to the behavioral choice in internal control information disclosure.Further research shows that the mode of behavior choice in internal control information disclosure is gradually changing from concealing internal control material weakness to gradually reducing the severity of material weakness.The above conclusions are still valid.The research conclusion of this paper has certain reference significance for the effective governance of behavior choice in internal control information disclosures.
