ナイジェリアの上場企業2006-2015年のデータを用い、環境・社会・ガバナンスの各開示が企業業績(ROA、Tobin's Q)に与える影響を検証。環境・社会開示はROAに有意な正の効果を持つが、ガバナンス開示は有意でない。企業は環境保護への寄付や代替エネルギー導入など環境配慮政策の開示を推奨。

Using Nigerian listed firms from 2006-2015, this study examines the impact of environmental, social, and governance disclosures on firm performance (ROA and Tobin's Q). Environmental and social disclosures significantly positively affect ROA, while governance disclosure does not. Recommends Nigerian firms adopt and disclose environmentally friendly policies, including donations and alternative energy sources.

📄 Abstract(原文)

Using samples taken from publicly traded companies in Nigeria between the years 2006 and 2015, the study examines the impact of sustainability disclosures on company performance by taking into account environmental, social, and governance sustainability characteristics. Through corporate reporting, investors and other stakeholders in Nigeria and elsewhere demand a comprehensive view of the business. The measurement and disclosure of various non-financial information as well as a company's performance in relation to the objective of sustainable development is the subject of sustainability reporting. It entails incorporating environmental, social, and governance factors into portfolio construction, risk management, investment analysis, and security selection (ESG Matters, 2015). Pooled ordinary least squares regression was used for the analysis of the variables specified in the models because the data used for the work is pooled data. Descriptive and inferential statistics were used to identify the possible environmental, social, and corporate governance specific characteristics and exogenous factors that would affect the firm's performance. Environmental sustainability disclosures have a significant positive effect on accounting performance measured here with return on assets, while the variable social sustainability disclosure has a significant positive effect on accounting performance measured here with return on assets, according to the results of Pooled ordinary least squares multiple regression using ROA and Tobin's Q measures of performance. Companies in Nigeria should implement and disclose environmentally friendly policies, such as contributing to environmental protection through donations and providing an alternative energy source in light of the carbon emissions generated by using more energy-intensive assets and natural resources.
