中国A株上場企業の2015〜2023年パネルデータを用い、ESG格付の分断が投資と資金調達の満期ミスマッチを悪化させることを示す。金融制約の強化、情報透明性の低下、硬直的な営業費用がメカニズムとして働き、非国有企業・中小企業・低TFP企業で影響が顕著。メディア監視（特にポジティブ報道）は緩和要因となる。格付分断は投資効率を低下させ、デフォルト頻度とリスクテイクを高める。
English
Using Chinese A-share panel data (2015–2023), this study shows ESG rating divergence aggravates corporate maturity mismatch between investment and financing. Mechanisms include tightened financial constraints, reduced information transparency, and rigid operating costs, pushing firms toward short-term debt. Effects are stronger for non-SOEs, SMEs, low-TFP firms, and less competitive industries. Media supervision, especially positive coverage, mitigates the mismatch, while divergence also lowers investment efficiency and raises default risk.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SSBJ基準の策定や有報でのサステナビリティ開示拡大が進む日本では、格付機関間の評価分断が企業の資金調達コストや財務安定性に与える影響は看過できない。本稿は格付調和と開示透明性の制度的価値を、金融リスクの観点から裏付ける材料を提供する。
In the global GX context
As ISSB standards are adopted and CSRD/SEC climate rules expand, this paper quantifies a systemic cost of ESG rating fragmentation: it distorts corporate financing structure and raises default risk. It strengthens the case for global harmonization of rating methodologies and for integrating sustainability transparency into financial regulation.
👥 読者別の含意
🔬研究者:ESG格付分断を財務リスク・満期構造の観点から定量化した実証枠組みとして、格付調和や開示規制の効果研究に応用できる。
🏢実務担当者:格付機関間の評価差が自社の資金調達条件や債務構成に影響しうる点を踏まえ、複数格付の比較と投資家向け説明の強化が有効。
🏛政策担当者:ESG格付基準の調和とメディア等の外部ガバナンス強化、サステナビリティ情報透明性の金融規制への統合が政策課題となる。
📄 Abstract（原文）
This study examines whether and how ESG rating divergence affects corporate maturity mismatch between investment and financing, using panel data from China’s A-share listed firms over the period 2015–2023. We employ fixed-effects models as the baseline specification and further apply instrumental variable estimation, propensity score matching, and a battery of robustness checks to address endogeneity and robustness concerns. We also introduce media supervision as a moderating variable to examine its governance role. We establish five main findings. First, ESG rating divergence significantly aggravates corporate maturity mismatch. Second, the underlying mechanism operates through tightened financial constraints, deteriorated information transparency, and rigid operating costs, which force firms to expand short-term debt while contracting long-term liabilities. Third, heterogeneity analyses reveal stronger effects for non-state-owned enterprises, small and medium-sized enterprises, firms with low total factor productivity, and firms in less competitive industries. Fourth, media supervision, particularly positive media coverage, mitigates the severity of maturity mismatch by counteracting rating inconsistency, whereas negative coverage amplifies it. Fifth, ESG rating divergence reduces corporate investment efficiency, especially by exacerbating underinvestment, and increases expected default frequency and risk-taking propensity. These findings highlight ESG rating fragmentation as a systemic amplifier of financial risk that undermines corporate resilience and impedes progress toward the Sustainable Development Goals, especially SDG 9 and SDG 13. Policy implications include harmonizing ESG rating standards, strengthening media-based external governance, and integrating sustainability information transparency into financial regulation to align corporate financing behavior with long-term sustainable investment.
