In this paper, we construct a content analysis structure to explore whether corporate governance information in voluntary disclosures can predict management expenses in the next term. Employing the site visit information disclosure of firms listed on the Chinese A-share market from 2012 to 2021, we find that corporate governance information disclosure is motivated by ownership concentration,and that corporate governance information can predict management expenses and comprises incremental information, indicating that the content analysis we construct is valuable and the disclosure of corporate governance information can mitigate the agency problems.There is a difference between state-owned listed firms and nonstate-owned listed firms.
