Using data of listed firms on Hochiminh Stock
Exchange, the study examines determinants of corporate
disclosure in financial statements. In line with the
literature, the findingsshow that firm size, the use of
financial leverage and the presence of supervision board
have a positive influence on corporate disclosure.
Furthermore, auditing firm (whether a Big4 or not) also
plays an important role in the degree of information
disclosure by firms.Contradicting to the literature,
however state ownership and the proportion of nonexecutive
members in director board show a negative
relation to corporate disclosure level. These counter
factscanbe explained by real situations of Vietnam over
the studied period. Finally, the concurrent role between
chair of director board and managing director reduces
corporate disclosure degree, as predicted by the agency
theory.
