Evidence from listed companies with directors’ ties.

Second, based on the connection between the transmission of information by the directors and the maintenance of their reputation, the inquiry letter has an indirect impact on the receiving company which has the relationship with the inquired company’s directors, that is, the readability of the annual report of the receiving company has also been significantly improved; third, the company with a strong external governance environment is inquired, which can significantly improve the readability of the annual report of the receiving company.
