ナイジェリア証券取引所上場70社（2010-2019年）を対象に、サステナビリティ報告の経済・社会・環境開示が企業業績（利益率・株価）に与える影響をパネル回帰で分析した。経済・社会開示は利益率と市場価値に有意な正の効果を持つ一方、環境開示はどちらにも有意な効果がなかった。著者は環境開示の遅れを指摘し、政府規制と開示品質の向上を提言している。
English
Panel regression on 70 Nigerian-listed firms (2010-2019) tests how economic, social, and environmental disclosures affect profit margin and share price. Economic and social disclosures show significant positive effects on both performance measures, while environmental disclosure shows no significant effect. The authors urge stronger environmental disclosure and government regulation in Nigeria.

日本のGX文脈において
新興国における開示と企業価値の関係を示す実証例として、SSBJ・有報サステナビリティ開示の効果を議論する日本の実務家・研究者にとって比較材料になる。環境開示が業績に結びつきにくい段階的発展の構図は、日本企業の開示高度化の相対的位置づけにも示唆を与える。
In the global GX context
Adds emerging-market evidence to the global disclosure literature (TCFD/ISSB/CSRD), showing that economic and social disclosures correlate with performance while environmental disclosure lags. Useful for understanding how disclosure maturity and regulation shape the financial materiality of ESG reporting outside advanced economies.

📄 Abstract（原文）
The study investigated the effect of sustainability reporting on the corporate performance of companies quoted on the Nigerian Stock Exchange. The measures for corporate performance used in the study are profit margin (PM) and market value indicated by share price (SP). The three dimensions of sustainability reporting examined are namely; economic, social, and environmental disclosures. The ex-post factor research design was employed and after filtering the population of listed companies, a sample of 70 listed companies drawn from oil and gas, telecommunication, and manufacturing industries in Nigeria with complete and comprehensive data for the period under review (2010-2019) was used for the study. A series of preliminary analyses such as descriptive statistics, correlation, and multicollinearity analysis were first conducted. Next, the panel co-integration test was conducted to examine the presence of a longrun relationship between the variables, and then finally the panel regression was conducted to examine the relationship between sustainability reporting and corporate performance. The findings of the study revealed that (i) Economic performance disclosure and social performance disclosure have a significant positive effect on the net profit margin of companies listed on the Nigeria Stock Exchange (ii) Environmental performance disclosure has no significant effect on the net profit margin of companies listed on the Nigerian Stock Exchange, (iii) Economic performance disclosure and social performance disclosure has a significant positive effect on the market value of companies listed on the Nigeria Stock Exchange, (iv) Environmental performance disclosure has no significant effect on market value of companies listed on the Nigerian Stock Exchange The study recommends that environmental disclosures have been lagging critically behind economic and social disclosure, thus companies need to pay more attention to addressing and disclosing on their environment. The study also recommends that there should be some regulation on environmental disclosures by the government for companies in Nigeria and companies should endeavour to improve not just economic disclosures but the quality of these disclosures.
