國際化程度與董事會結構對碳揭露之影響

近年來，科技的進步促使商業全球化。然而，由於環境遭受碳排放的汙染，使得人們開始對碳排放資訊更加重視。公司治理中的董事會在資訊揭露中扮演一個重要的角色。本研究以2013年至2017年台灣上市（櫃）公司為研究樣本採用logistict迴歸分析，探討國際化程度與董事會結構對碳揭露之影響。實證結果顯示，國際化程度對碳揭露呈正相關；董事會規模、獨立董事比例和董監持股比例對碳揭露呈顯著正相關；而女性董事比例則對碳揭露呈顯著負相關。再者，董事會規模與國際化程度之交乘項對碳揭露具顯著正面影響；而女性董事比例、董監持股比例與國際化程度之相互作用對碳揭露則具顯著負影響。最後，額外測試結果顯示，企業之董事會結構指標愈好且國際化程度愈高時，愈會執行碳揭露。

In recent years, advances in technology have prompted globalization of business. However, people begin pay much attention to the carbon emissions information owing to the environment pollution by carbon emissions. The board of directors in corporate governance play an important role refer to information disclosure. This study uses the sample of firms listed in Taiwan Stock Exchange from 2013 to 2017. In addition, the study uses logistic regression analysis to examine the impact of internationalization and board composition on carbon disclosure. The empirical results show that the degree of internationalization is positively correlated with carbon disclosure. Moreover, the size of the board of directors, the proportion of independent directors and the proportion of directors shareholdings were significantly positively correlated with carbon disclosure. The proportion of female directors is significantly negatively correlated with carbon disclosure. Furthermore, the interaction effect of the size of the board of directors and the degree of internationalization has a significant positive relationship on carbon disclosure. However, the interaction effect of the ratio of female directors, the proportion of directors shareholdings and the degree of internationalization has a significant negative relationship on carbon disclosure. Finally, the additional test results show that the firms with the better the company's board composition indicators and the higher the degree of internationalization would have more carbon disclosure information.
