Board diversity and firm performance in Chinese manufacturing firms: Moderating role of CEO duality

This study explores the relationship between board diversity and firm performance, with a focus on the moderating role of CEO duality in Chinese manufacturing firms. This study applies panel fixed-effect regression models for the period 2008-2022, and findings show that board diversity is positively associated with firm performance, and CEO duality negatively moderates the relationship. However, the findings also show that a highly diversified board can minimize the negative effect of CEO duality and increase the firm's performance. Furthermore, the findings broaden the understanding of board attributes, showing that the education index is more evident among other board attributes for firm performance. This study verifies its results using the two-step system generalized method of moments approach and different board attributes in robust tests. The findings suggest that strategic efforts to promote board diversity may increase the board's monitoring function and control managerial opportunism, ultimately improving firm performance in the Chinese business landscape.JEL CLASSIFICATIONS: G30; G34; L25
