日本語

本研究は欧州NUTS-2地域を対象に2000〜2024年のパネルデータを用い、炭素強度の条件付きβ収束を二方向固定効果モデルと空間パネルモデルで検証した。空間依存を考慮しても条件付き収束は統計的に有意で、収束率は年約11〜13.3%と推定された。気候由来エネルギー需要と産業構造は炭素強度の成長と有意に関連し、地域の異質性と空間依存を踏まえた場所別政策の重要性を示す。

English

Using 2000–2024 panel data for European NUTS-2 regions, this study tests conditional β-convergence in carbon intensity via two-way fixed-effects and spatial panel models. Conditional convergence remains significant after accounting for spatial dependence, with annual rates of roughly 11–13.3%, though dynamic-panel checks show greater uncertainty. Climate-driven energy demand and industrial structure are significantly linked to carbon-intensity growth, supporting place-based transition policy.

日本のGX文脈において

日本では地域別脱炭素（自治体・地域電力）の政策設計が議論されており、地域間収束と空間依存の実証手法は日本の地域GX政策や地域別排出データ分析に応用可能。SSBJ開示とは直接の接点は薄い。

In the global GX context

Adds empirical evidence on regional convergence and spatial dependence to the global decarbonization literature, informing place-based transition policy design relevant to EU climate-neutrality targets and comparable regional disclosure efforts.

📄 Abstract（原文）

European regions aim to achieve climate neutrality. This requires the improvement of the carbon efficiency of their energy systems despite the substantial differences in climate conditions and economic structure. This study investigates whether carbon intensity converges across European NUTS-2 regions and examines the role of climate-driven energy demand and spatial interactions in the regional energy transition. Specifically, we use panel data from the period 2000–2024 and investigate the conditional β-convergence based on two-way fixed effects and spatial panel models. The results reveal evidence of conditional convergence, which remains statistically significant after accounting explicitly for spatial dependence, with persistent spatial dependence and point estimates suggesting slower adjustment in regions with initially high carbon intensity. The baseline two-way fixed-effects model implies an annual convergence rate of approximately 13.3%, while spatial specifications that explicitly account for regional dependence yield somewhat lower but comparable rates of approximately 11%. Dynamic-panel robustness checks indicate greater uncertainty regarding the magnitude and statistical precision of the convergence relationship. Climate-driven energy demand and industrial structure are significantly associated with annual carbon-intensity growth. Spatial panel models provide additional evidence of conditional convergence and reveal significant spatial dependence, while the total association between climate-driven energy demand and carbon-intensity growth remains positive across alternative spatial specifications. These findings highlight the importance of place-based energy transition policies that account for regional heterogeneity and spatial dependence in regional decarbonization dynamics.
