IDXCarbon発足後のインドネシアで、炭素排出開示(CED)が企業価値(Tobin's Q)に与える影響と、コーポレートガバナンス(GCG)の調整効果を基礎素材セクター64社・256観測で検証。CED・GCGいずれも企業価値に有意な影響を与えず、GCGの調整効果も確認されなかった。炭素市場の初期段階では市場が炭素情報を価格に織り込んでいないことを示唆する。
English
Using 64 Basic Materials firms (256 observations) on the Indonesia Stock Exchange 2022–2025, this study tests whether carbon emission disclosure (CED) affects firm value (Tobin's Q) and whether governance (independent commissioner ratio) moderates it. Neither CED nor GCG shows a significant effect, and GCG does not moderate the relationship (homologiser moderator). Results suggest Indonesia's early-stage carbon market has not yet priced carbon disclosure.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
新興国炭素市場の黎明期における開示の価格織り込みを実証する点は、SSBJ・有報での気候開示義務化が進む日本にとって、規制整備と市場評価のタイムラグを考える上で示唆に富む。
In the global GX context
Offers rare empirical evidence on whether carbon disclosure is priced in an emerging carbon market's early phase, complementing ISSB/TCFD scholarship that mostly draws on mature EU/Japanese markets.
👥 読者別の含意
🔬研究者:新興国における炭素開示と企業価値の非有意な関係を、頑健性検証込みで示す実証データ点として活用できる。
🏢実務担当者:炭素市場初期段階では開示がまだ評価に直結しない可能性を示し、開示品質・第三者検証の重要性を裏付ける。
🏛政策担当者:開示基準の標準化と独立取締役監督の実効性強化が、炭素情報の市場価格織り込みに必要であることを示唆する。
📄 Abstract(原文)
The launch of IDXCarbon in September 2023 and the start of international carbon trading in January 2025 have made Carbon Emission Disclosure (CED) increasingly relevant to investor valuation. This study analyzes the effect of CED on firm value and the role of Good Corporate Governance (GCG) as both a direct predictor and a moderator of this relationship among Basic Materials companies listed on the Indonesia Stock Exchange during 2022–2025. Using purposive sampling, the sample comprises 64 companies (256 observations). Firm value is measured by Tobin’s Q, CED by an 18-item checklist, and GCG by the proportion of independent commissioners, with ROA and leverage as control variables. The data are analyzed using Moderated Regression Analysis with a Random Effects Model (Panel EGLS), selected through the Chow and Hausman tests, and robustness is examined through FEM comparison and robust standard errors. The results show that CED has no significant effect on firm value (β = 0.370; p = 0.555), GCG has no significant effect (β = −0.608; p = 0.405), and GCG does not moderate the CED–firm value relationship (β= 0.208; p = 0.882), classifying GCG as a homologiser moderator. These findings are consistent across all robustness tests and suggest that the Indonesian capital market has not yet priced carbon emission information during the early phase of its carbon market. Firms should therefore improve the quality and verification of emission disclosures, while regulators should standardize disclosure requirements and strengthen the effectiveness of independent commissioner oversight.
