Environmental information disclosure is gradually gaining popularity, especially under the severe environmental pollution. Analyzing the relations among environmental information disclosure (EID), corporate governance and economic performance by employing a cross-disciplinary and a cross-sectional approach is a new start for improving environmental disclosure. The Ordinary Least Square results suggest that, firstly, firm size and ownership structure have significant positive relations with EID and economic performance. Secondly, the factors of corporate governance including the equity concentration ratio, logarithm of management incentive, logarithm of management shareholding, the board size and the number of directors, all have positive influences on EID. Thirdly, corporate governance has an impact on firm’s economic performance. Lastly, this study reveals that EID positively affects firm’s financial performance—solvency, operational capability and profitability. It is expected that this study can highlight the importance of environmental awareness of professional genre and enhance the environmental disclosure.
