中国上場企業と社債を対象に、都市別の日次気象データと年次報告書テキスト（MacBERT）を統合し、物理的気候リスクの曝露と経営者の注意の乖離を測定した。相対的な乖離が大きい上位層では信用スプレッドが高く、高乖離状態が持続する企業ほどスプレッドが高い。キャッシュフローの変動性が高く取締役会が小さい企業でこの関連が強い。投資家が物理リスクと経営者の注意を同時に評価していることを示す。
English
Using Chinese listed firms and their bonds (2012–2024), this study combines city-level weather data, annual-report text analyzed with MacBERT, and bond trading data to measure the gap between physical climate risk exposure and managerial attention. Credit spreads are higher in the upper part of the relative exposure–attention gap distribution, and persistent high-gap states are associated with higher spreads. The association is stronger for firms with volatile cash flows and smaller boards, and robust to placebo and entropy-balancing tests. Investors price physical risk and managerial attention jointly.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SSBJ・有価証券報告書での気候関連開示が進む日本では、物理的リスクの「開示された注意」と実際の曝露の乖離が社債スプレッドに反映される可能性を示唆する。投資家対応やリスク管理の実効性を測る指標として、テキスト分析を用いた開示評価の重要性が高まる。
In the global GX context
As ISSB/TCFD-aligned disclosure becomes mandatory, this paper shows that markets price the alignment between disclosed managerial attention and actual physical risk exposure, not just the exposure itself. It offers a text-based method to assess disclosure quality and its credit implications, relevant to CSRD and SEC climate disclosure debates.
👥 読者別の含意
🔬研究者:物理的気候リスクと開示テキストの乖離をNLPで定量化し、信用スプレッドとの関連を実証した手法は、開示の実効性評価研究に応用可能。
🏢実務担当者:年次報告書での気候リスク記述が実際の曝露と整合しているかが社債調達コストに影響しうるため、開示の整合性確保が重要。
🏛政策担当者:気候関連開示の規制において、形式的な注意喚起だけでなく実曝露との整合性を促す枠組みの必要性を示唆。
📄 Abstract（原文）
As climate change intensifies, extreme weather increasingly disrupts corporate operations and debt-servicing capacity, making physical climate risk more important in credit assessment. Yet firms’ exposure may not align with the managerial attention disclosed in annual reports, and whether bond markets price this mismatch remains unclear. Using Chinese listed firms and their outstanding corporate debt securities from 2012 to 2024, this study integrates daily city-level weather data, annual-report text, and bond trading data. Historical extreme-precipitation exposure measures local physical risk, while MacBERT identifies managerial attention. The difference between the standardized measures defines the physical climate risk–attention gap. The results show that investors assess physical risk and managerial attention jointly. Credit spreads are higher in the upper part of the relative exposure–attention gap distribution, and persistent high-gap states are associated with higher credit spreads. The association is stronger among firms with more volatile cash flows and smaller boards and remains stable across information-timing placebo tests, entropy-balancing analyses, and alternative measurement specifications. These findings explain how the alignment between physical risk and managerial attention is reflected in corporate bond prices and inform climate disclosure, bond-market risk assessment, and climate resilience in the real economy.
