本研究は、1995年から2018年のドイツの製造業18業種において、気候政策の不確実性が全要素炭素生産性に与える影響を分析。固定効果確率的フロンティアモデルで生産性を推定し、二段階システムGMMで関係を検証。エネルギー集約度が調整変数として機能し、低エネルギー集約産業では不確実性が生産性向上（ヘッジ行動）と関連する一方、高エネルギー集約産業では生産性低下（様子見行動）と関連することを発見。安定した気候政策の重要性を示唆。

This study analyzes the impact of climate policy uncertainty (CPU) on total factor carbon productivity (TFCP) across 18 German manufacturing industries from 1995 to 2018. Using a fixed-effects stochastic frontier model and two-step system GMM, it finds that energy intensity moderates the relationship. In less energy-intensive industries, CPU is positively associated with TFCP growth (hedging behavior), while in high energy-intensive industries, it is negatively associated (wait-and-see behavior). The findings underscore the need for credible and stable climate policy.

日本のGX文脈において
日本のGX政策（カーボンプライシングや排出量取引）の不確実性が企業の投資行動に与える影響を理解する上で示唆に富む。特にエネルギー多消費産業への影響は、日本の製造業が直面する課題と類似。政策の安定性と信頼性が、企業の脱炭素投資を促進する鍵であることを示す。
In the global GX context
This paper provides empirical evidence on how climate policy uncertainty affects corporate carbon productivity, which is directly relevant to global climate disclosure and transition finance discussions. It highlights the importance of policy credibility for encouraging long-term investments in decarbonization, a key concern for the ISSB and TCFD frameworks.

📄 Abstract（原文）
Abstract This study examines how climate policy uncertainty (CPU) influences total factor carbon productivity (TFCP) across 18 German manufacturing industries from 1995 to 2018. TFCP is estimated using a fixed-effects stochastic frontier model, and the relationship between CPU and productivity is analyzed using a two-step system generalized method of moments. The results suggest that the relationship between CPU and TFCP is significantly moderated by industry energy intensity, revealing two contrasting responses to uncertainty: hedging and wait-and-see behavior. In relatively less energy-intensive industries, CPU is positively associated with TFCP growth, consistent with hedging behavior in which firms undertake incremental efficiency improvements in anticipation of future stringent climate policy. In contrast, in high energy-intensive industries, CPU is negatively associated with TFCP growth. This relationship is consistent with a wait-and-see response, whereby greater exposure to regulatory risk and higher adjustment costs increase the option value of delaying irreversible investments. The findings underscore the importance of credible and stable climate policy in reducing uncertainty and sustaining carbon-efficient.
