📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ基準の確定と有報でのサステナビリティ開示義務化が進む中、開示の経済的便益を新興国市場で示した実証は、義務化の正当化根拠として参考になる。ただしEAC固有の制度・市場構造のため直接の示唆は限定的。
In the global GX context
Adds emerging-market evidence to the global debate on whether mandatory ESG disclosure creates firm value, complementing ISSB/CSRD-driven disclosure-infrastructure research that has been dominated by EU and US samples.

📄 Abstract（原文）
Environmental, Social and Governance (ESG) reporting has become an increasingly important consideration in investment decisions, and firms that overlook ESG issues may face operational, legal, and reputational costs that can erode firm value. This study assessed the relationship between ESG reporting and firm value among companies listed on East African Community (EAC) securities exchanges. Applying a positivist philosophy and a longitudinal design, the study drew a purposive sample of 15 out of 93 listed EAC firms that disclose ESG information, based on inclusion criteria. The study obtained secondary data on ESG reporting and firm value from 2018 to 2024 from annual reports, sustainability reports, and securities exchange records, treating firm value as the dependent variable. Descriptive statistics and multivariate regression showed that ESG reporting exerted a statistically significant, positive effect on firm value. The study concludes that ESG reporting materially strengthens firm value and recommends that regulators tighten mandatory ESG requirements, that companies build more robust ESG reporting systems, and that investors factor ESG reporting into their decision-making.
