Earnings quality is calculated from four measurements while corporate governance structure is represented by ownership concentration, foreign ownership, board independence and CEO duality. In this study, CSP disclosure index is constructed in accordance with Thai institution guideline based on GRI (Global Reporting Initiative) framework in order to assess the extent of CSP. Regression analysis reveals a significant positive relationship between earnings quality and CSP.
