本論文は、米国企業2002-2023年のデータを用い、テキストベースの気候リスク指標と炭素強度指標を組み合わせ、気候リスクが企業の財務制約に与える因果的影響を検証。移行リスクは財務制約を強めるが、物理的リスクの影響は限定的。キャッシュフロー制約、顧客支援の低下、機関投資家の監視強化という3つの経路を特定。2SLS操作変数法で因果性を確認。
English
Using U.S. firm data from 2002-2023, this paper examines the causal impact of climate risk on corporate financial constraints, combining text-based climate risk measures with carbon intensity. Transition risks significantly tighten financing frictions, while acute physical risks have limited effects. Three channels are identified: constrained cash flow, reduced customer support, and heightened institutional investor scrutiny. 2SLS with population density as instrument confirms causality.

日本のGX文脈において
日本ではSSBJ開示義務化が迫る中、気候リスクが財務制約に与える影響の実証は、企業の開示対応と資本コスト管理に示唆を与える。移行リスクの重要性は、日本の政策・市場圧力にも通じる。
In the global GX context
This paper contributes to global climate finance literature by providing causal evidence that transition risks tighten financial constraints, relevant for TCFD/ISSB disclosure and transition finance frameworks. The text-based risk measure offers a methodological advance for analyzing climate disclosures.

📄 Abstract（原文）
ABSTRACT This research provides novel evidence on the role of climate risk in shaping corporate financial constraints, offering a fresh perspective on how exogenous environmental and regulatory pressures affect firm financing. Using a large sample of U.S. firms from 2002 to 2023, we leverage a text-based firm-level climate risk measure alongside traditional carbon intensity metrics, while financial constraints are captured through Altman’s Z score, Ohlson’s O score, and a textual measure. Our findings reveal that transition risks—stemming from policy, market, technological, and investor pressures—significantly tighten financing frictions, whereas acute physical risks have limited effects. We uncover three novel channels: constrained cash flow, limited customer support, and heightened institutional investor scrutiny. Using a 2SLS approach with state-level population density as an instrument, we provide robust evidence that climate risk causally exacerbates financial constraints. The results underscore the strategic importance of sustainable practices in enhancing financial resilience and offer actionable insights for managers, investors, and policy-makers navigating a rapidly evolving climate landscape.
