日本語

本研究は、EUの炭素国境調整メカニズム（CBAM）の移行期間が、中国の高炭素産業のESG環境スコアに与える短期的な影響をPSM-DID法で分析。その結果、CBAM移行期間は規制対象企業の環境パフォーマンスを有意に抑制することが判明。メカニズム分析では、資金制約の増大が主要な経路であることを特定。国有企業、監査品質の低い企業、女性役員比率の高い企業で負の影響が顕著。政策提言として、グリーン移行融資メカニズムの構築、国内炭素市場改革の加速、国際的な技術調和の強化を提案。

English

This study uses PSM-DID to analyze the short-term impact of the EU CBAM transition period on ESG environmental scores of Chinese high-carbon firms. Results show the CBAM transition significantly inhibits environmental performance, with increased financing constraints as the core mediating channel. Negative effects are stronger for state-owned enterprises, firms with lower audit quality, and higher female executive proportion. Recommendations include establishing green transition financing mechanisms, accelerating domestic carbon market reforms, and strengthening international technical harmonization.

日本のGX文脈において

日本企業にとっても、EU CBAMは輸出競争力に直結する重要課題。本論文が示す資金制約の増大は、日本企業がCBAM対応を進める上で、グリーン移行融資の必要性を示唆する。特に、高炭素産業の日本企業は、CBAMによるコスト増加が低炭素投資を圧迫する可能性に留意すべき。

In the global GX context

As the world's first carbon border adjustment mechanism, CBAM is a landmark climate policy with global trade implications. This paper provides early empirical evidence of its short-term negative impact on regulated firms' environmental performance, highlighting financing constraints as a key channel. The findings underscore the need for supportive transition finance and carbon market reforms, relevant for policymakers and firms worldwide facing similar carbon pricing mechanisms.

👥 読者別の含意

🔬研究者:Provides empirical evidence on CBAM's real-world effects on firm-level ESG performance, contributing to the literature on carbon border adjustments and corporate environmental behavior.

🏢実務担当者:Highlights that compliance costs and financing constraints from CBAM may crowd out low-carbon investments, urging firms to seek green financing and improve audit quality.

🏛政策担当者:Suggests that policymakers should establish targeted green transition financing mechanisms and accelerate domestic carbon market reforms to mitigate negative impacts of CBAM.

📄 Abstract（原文）

The European Union’s Carbon Border Adjustment Mechanism (CBAM), the world’s first system to impose tariffs on the carbon emissions of imported products, commenced its transition period in October 2023 and is scheduled for full implementation in January 2026. This mechanism exerts a profound impact on the global trade landscape and corporate environmental management practices. Taking the CSI All Share Index constituent companies as a research sample, this paper empirically evaluates the impact of the CBAM transition period on the environmental scores of Chinese export enterprises utilizing the Propensity Score Matching Difference-in-Differences (PSM-DID) method. The results indicate that the CBAM transition period significantly inhibits the short-term environmental performance of regulated enterprises. Mechanism analysis reveals that increased financing constraints serve as a core mediating channel, wherein escalated compliance costs and compressed cash flows crowd out resources for low-carbon investments. Furthermore, heterogeneity analysis demonstrates that the negative impact is more pronounced among state-owned enterprises, firms with lower audit quality, and firms with a higher proportion of female executives. Accordingly, the study recommends establishing targeted green transition financing mechanisms, accelerating domestic carbon market reforms, and strengthening international technical harmonization to build corporate resilience against global climate governance shocks and promote sustainable growth.
