The independent director mechanism has been implemented for some time, however, whether this mechanism can effectively perform its monitoring functions has become a topic of concern since corporate governance disability events successive occur in recent years. This study uses case analysis and related statistical data to summarize the problems faced by the current independent director mechanism. Finally, this research makes recommendations for 4 aspects of the independent director system, including nomination and elect ion of independent directors, number of board seats for independent directors, independence of independent directors, and differentiate the rights and responsibilities of independent directors. We hope these findings and suggest ions can provide contribution to effectively implement the independent director mechanism.
