本論文は、EU加盟国25カ国・39産業のパネルデータを用い、エネルギー市場統合（EMI）が低炭素技術革新（LCTI）の量と質に与える影響を分析。EMI指数を構築し、ポアソン擬似最尤推定と機械学習による頑健性検証を実施。結果、EMIはLCTIの量と質を有意に向上させ、研究開発投資と国際的知識波及が経路であることを示した。
English
This paper uses a country-industry-year panel of 25 EU member states and 39 industries from 2003-2020 to examine the effect of energy market integration (EMI) on low-carbon technology innovation (LCTI) quantity and quality. An EMI index is constructed, and Poisson PML estimation with three-way fixed effects, Bartik IV, and double/debiased ML are employed. Results show EMI significantly boosts both LCTI quantity and quality, operating through R&D investment and cross-border knowledge spillovers.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文はEUのエネルギー市場統合が低炭素イノベーションに与える正の効果を実証。日本の電力システム改革やアジア域内のエネルギー協力にも示唆を与える。ただし、日本がEUのような超国家的統合に参加していない点は留意。
In the global GX context
This paper provides causal evidence that regional energy market integration can drive low-carbon innovation, relevant for global climate policy discussions on market design and cooperation. The findings support the rationale for deepening integration in regions like the EU and could inform initiatives such as the ASEAN Power Grid or African single energy market.
👥 読者別の含意
🔬研究者:Offers robust empirical evidence on the innovation effects of energy market integration, useful for scholars in energy economics and environmental innovation.
🏛政策担当者:Demonstrates that deeper energy market integration can complement direct R&D subsidies, suggesting a dual focus on integration and innovation policy.
📄 Abstract（原文）
Achieving carbon neutrality requires simultaneous advances in both the quantity and quality of low-carbon technology innovation (LCTI). This paper uses a country–industry–year three-dimensional panel dataset covering 25 EU member states and 39 two-digit NACE Rev. 2 industries over the period 2003–2020 to examine the effects of energy market integration (EMI) on LCTI quantity and quality. An EMI index is constructed based on cross-national energy price dispersion, and the analysis employs Poisson pseudo-maximum likelihood estimation with three-way fixed effects, complemented by a Bartik instrumental variable and double/debiased machine learning as supporting robustness evidence. Results show that: (1) EMI exerts significant positive effects on both LCTI quantity and quality; (2) Mechanism tests reveal that EMI operates through two channels: expansion of energy R&D investment and intensification of cross-border knowledge spillovers; (3) Heterogeneity analysis shows that the promoting effects are concentrated in countries with adequate R&D investment and active energy market competition, and in industries with low emission intensity and low energy intensity. These findings suggest that deepening regional energy market integration constitutes a meaningful institutional complement to conventional low-carbon innovation policy.
