2021〜2025年のS&P100企業を対象に、BloombergのESGスコアとROEの関係をプールドOLSで分析。ESGスコアはROEと正の関係があるが統計的に有意ではなく、負債比率とTobin's Qが有意。モデルはROEの分散の41.7%を説明。ESGスコアは開示の広さを測るもので、業績改善との明確な関連は見られない。
English
Analyzes the relationship between Bloomberg ESG scores and ROE for S&P 100 firms from 2021-2025 using pooled OLS. ESG score is positively but not significantly related to ROE, while leverage and Tobin's Q are significant. The model explains 41.7% of ROE variance. Concludes that higher ESG disclosure scores do not measurably improve financial performance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ開示が始まり、ESG情報の開示が進む中、開示スコアと財務パフォーマンスの関係を示す本研究成果は、投資家対応や開示戦略を考える上で参考になる。ただし、米国データに基づくため、日本企業への適用には注意が必要。
In the global GX context
Contributes to the global debate on whether ESG ratings reflect performance or disclosure. With ISSB and CSRD pushing for standardized disclosure, this study highlights that Bloomberg's ESG score measures disclosure breadth, not actual sustainability performance, urging investors to look beyond ratings.

📄 Abstract（原文）
This paper examines the relationship between ESG ratings and the financial performance of S&P 100 firms from 2021 to 2025. This study uses pooled OLS regression on Bloomberg Terminal data, regressing Return on Equity against ESG Score, Net Debt/Equity, and Tobin's Q across 447 firm-year observations from 100 of the United States largest publicly listed companies. ESG Score is positively linked to ROE but not statistically significant (β = 3.740, p = 0.268). Net Debt/Equity (β = 28.899, p < 0.001) and Tobin's Q (β = 4.166, p < 0.001) are both significant. The regression model explains 41.7% of the variance in ROE (R² = 0.4174, F = 105.82). Bloomberg's ESG rating measures how broadly a firm reports on ESG topics, not how it performs on them. No measurable improvement in ROE is found from higher Bloomberg ESG scores in the S&P 100 over this period. Existing literature in this area predominantly uses the S&P 500, Refinitiv or MSCI scores, and data ending before 2021. This paper differs from prior literature in that it uses the S&P 100, Bloomberg's composite, the 2021–2025 period, and ROE rather than ROA.
