アジア市場の非金融上場企業を対象に、生物多様性への影響削減がESGスコアを約13.5%向上させることを実証。固定効果回帰、操作変数法、傾向スコアマッチングを用いて頑健性を確認し、特に中小・新興企業で効果が大きいことを示す。規制当局への生物多様性指標の組み込みや格付機関への実質的評価を提言。
English
Using firm-level data from Asian markets (2000-2024), this study finds that biodiversity impact reduction improves ESG scores by about 13.5%, with the strongest effect on the social pillar. Robust to IV and matching methods, the benefits are largest for smaller and younger firms. Implications for regulators, rating agencies, and firms with limited resources.

In the global GX context
This paper contributes to global disclosure scholarship by providing empirical evidence from Asia, a region often underrepresented. It supports the integration of biodiversity indicators into frameworks like ISSB and CSRD, and highlights the value of substantive biodiversity action over symbolic disclosure.

📄 Abstract（原文）
This study examines whether biodiversity impact reduction improves environmental, social, and governance (ESG) performance among publicly listed non-financial firms in Asian markets, a region that is rich in biodiversity yet underexamined in the finance literature. Using firm-level data drawn from the LSEG Eikon database covering Asian economies between 2000 and 2024, the analysis links a firm-level biodiversity impact reduction indicator to the overall ESG score and to its environmental, social, and governance pillars. The empirical strategy combines fixed-effects panel regressions with instrumental-variable estimation, propensity score matching, and placebo tests, and it further examines how the relationship varies with firm size and firm age. The results show that firms undertaking biodiversity impact reduction achieve ESG scores approximately 13.5 percent higher than otherwise comparable firms, and the effect holds across all three pillars, with the social pillar responding most strongly. The instrumental-variable and matching estimates confirm that the association is robust and economically meaningful, and the benefits are largest for smaller and younger firms that gain most from signalling environmental commitment. These findings imply that regulators should embed explicit biodiversity indicators in ESG reporting frameworks, that rating agencies should reward substantive biodiversity practice rather than symbolic disclosure, and that firms with limited sustainability resources stand to gain the most from biodiversity action.
