This study investigates the effectiveness of the dual-board corporate governance mechanism on enterprise risk management and financial stability in emerging markets. Taking into account both market risk and total risk, we find activities of both boards, board of directors and the supervisory board, in these companies affect corporate risk-taking behaviors significantly, but shed light on different aspects. These findings are of interest and counter-intuitive since prior research concludes ineffectiveness of the dual-board system in China. More detailed issues, such as the endogeneity of board activities and characteristics, reciprocal causality between board behaviors and risk-taking issues, effects of political/governmental policies and ownership structure of controlling shareholders on board behaviors, asymmetrical monitoring effects of two boards on companies with various levels of financial risk, and non-linear effects of meeting frequencies of two boards, are addressed to help better understand the corporate governance-enterprise risk management relationship.
