Throughout, this study will use correlation and regression analysis in the SPSS software to determine the effects of corporate governance practices on Market Valuation. In analyzing firms＇ market valuation, we will use the Tobin＇s Q formula and for the corporate governance compliance, we will look at 4 criteria to compare with market valuation, which are （1） Board of Director＇s composition, （2） Board of Director＇s remuneration （salaries）, （3） Board of Director＇s training and development, （4） Board of Director＇s meeting. In order to determine the effects between the corporate governance compliance and market valuation, we will use regression analysis. Based on the correlation analysis, the first null hypothesis must be rejected and the alternative hypothesis is accepted, in which dependent variable and independent variables are significantly correlated with BOD remuneration and BOD training availability. Overall, there is a significant relationship between Tobin＇s Q and independent variables （BOD remuneration and BOD training）. This study also recommends that for the company who did not comply with the code, they should follow the best practice because it will be a pivotal weapon in facing with the fierce competition in era globalization.展开更多
