日本語

EU ETSが電力部門の脱炭素化に与える影響を、パネル計量分析、企業調査、市場分析の混合手法で検証。再エネ容量拡大には補助金や規制の安定性が重要で、ETSは主に卸電力価格への転嫁を通じて低炭素技術に収益をもたらす。間接コスト補償の炭素係数と市場の転嫁指標の乖離も示す。

English

This study examines the EU ETS's role in power sector decarbonization using panel econometrics, a firm survey, and market analysis. It finds that subsidies and regulatory stability drive renewable capacity expansion more than carbon prices, while the ETS mainly influences wholesale prices and redistributes revenues to low-carbon technologies. Cross-country differences in indirect cost compensation factors are highlighted.

日本のGX文脈において

日本では2026年度の排出量取引制度本格稼働を控え、炭素価格の投資誘因効果と補助金・市場設計との相互作用は重要な論点。本論文の示唆は、日本の制度設計や再エネ導入政策の検討に参考となる。

In the global GX context

This paper provides robust empirical evidence on how carbon pricing interacts with renewable support policies, relevant for global discussions on ETS design, carbon cost pass-through, and indirect cost compensation. It informs policymakers and researchers working on carbon pricing effectiveness and market-based decarbonization mechanisms.

📄 Abstract（原文）

Understanding the role of carbon pricing and complementary support schemes in renewable energy deployment is increasingly important for the decarbonisation of power markets. The analysis employs a mixed-methods approach: a panel econometric analysis of installed renewable capacity across European countries from 2013 to 2024, a cross-country survey involving 127 firms, and an hourly market-based estimation of inframarginal rents. Econometric evidence indicates that energy and fuel subsidies consistently drive the expansion of renewable energy capacity. The survey results corroborate that investors prioritise subsidies, regulatory stability, and long-term revenue certainty over the price of EU allowances in renewable energy investment decisions. The market-based analysis demonstrates that the system primarily influences the power sector through wholesale electricity price formation and carbon cost pass-through, thereby generating persistent inframarginal revenues for low-carbon technologies. A comparison between the regulatory carbon factors used for indirect cost compensation and the observed market-based pass-through indicators reveals substantial cross-country differences. The evidence suggests that the system currently functions more as a mechanism for wholesale price transmission and revenue redistribution than as an independent driver of renewable energy investment, underscoring the importance of complementary support policies and electricity market design.
