本研究は、ナイジェリアの消費者財上場企業20社を対象に、サステナビリティ報告（ESG開示）が企業価値に与える影響と、監査品質の調整効果を分析。ガバナンスと社会開示は企業価値を有意に向上させるが、環境開示の効果は弱い。監査品質（監査法人の交代）はガバナンス・社会開示の効果を強化するが、環境開示への影響は限定的。
English
This study examines the impact of sustainability reporting (ESG disclosure) on firm value for 20 listed consumer goods firms in Nigeria, with audit quality as a moderator. Governance and social disclosures positively and significantly affect firm value, while environmental disclosures have a weak, insignificant effect. Audit quality (auditor rotation) strengthens the effect of governance and social disclosures but does not significantly enhance environmental disclosure's impact.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
ナイジェリアの文脈ではあるが、ESG開示と監査品質の相互作用を示す実証研究として、日本企業の統合報告書や有報での開示品質向上に示唆を与える。特に、環境開示が企業価値に直結しない点は、日本のSSBJ基準におけるマテリアリティ評価の参考となる。
In the global GX context
This paper provides empirical evidence from an African emerging market on the value relevance of ESG disclosures and the role of audit quality. It contributes to the global discourse on disclosure assurance and ESG credibility, relevant for frameworks like ISSB and CSRD as they consider audit and assurance mechanisms.
👥 読者別の含意
🔬研究者:For researchers, it offers a developing-country perspective on the ESG–firm value nexus and the moderating role of audit quality, with implications for cross-country comparative studies.

📄 Abstract（原文）
This study examines the impact of sustainability reporting on firm value of listed consumer goods firms in Nigeria, with particular emphasis on the moderating role of audit quality. Panel data was obtained from the annual reports of 20 listed consumer goods firms over a ten-year period (2015–2024). Robust regression model was employed to take care of the presence of heteroskedasticity confirmed in the diagnostic test. The findings reveal that the governance and social disclosures had positive and significant effect on firm value, meanwhile, environmental disclosures showed weak and insignificant effect. The audit quality proxied by auditor rotation, not only has a significant and positive effect on firm value but also increases the effect of governance and social disclosures on firm value, and was able to increase the positive relationship of environmental disclosures but still insignificant effect. The findings indicate the significance of credible sustainability practices and high audit quality in enhancing long-term firm value. The study provides practical implications for corporate governance, investor confidence and regulatory policy by emphasizing the need for stronger ESG disclosure frameworks and improved audit assurance mechanisms.
