 The present study is concerned about the relationship between the board characteristics and intellectual capital efficiency in companies listed on the Iran and Iraq Stock Markets.A multivariate regression model is used for this study. Research hypotheses were tested using a ۹۰۳ firm-year observation sample from the Tehran Stock Exchange and ۲۸۰ firm-year observations from the Iraq Stock Exchange during ۲۰۱۲-۲۰۱۸ for both counties based on multiple regression patterns and pooled data techniques. The results show that there is a significant relationship between board characteristics and efficiency of intellectual capital, which means there is a negative and significant relationship between the board independence, the board size, CEO ownership, and CEO gender, and intellectual capital and a positive and meaningful relationship between CEO change and intellectual capital both in Iran and Iraq. However, while the relationship between board independence and intellectual capital is negative in Iraq, such a relationship is positive and significant in Iran.
