1990-2022年の108カ国のパネルデータを用いて、再生可能エネルギー消費の収束パターンを分析。グローバルな収束は確認されず、4つの異なる収束クラブが存在。所得とガバナンスが高いほど再生可能エネルギー比率が高いクラブに属する確率が高まる。政策は共通ではなく、各レジームに合わせた策定が必要。
English
Using panel data from 108 countries (1990-2022), this study finds no global convergence in renewable energy consumption, but identifies four distinct convergence clubs. Income and governance quality increase the probability of being in high-renewable clubs, while carbon intensity constrains upward transitions. Policies must be tailored to regime-specific conditions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は、日本のエネルギー転換経路が独自である可能性を実証的に示す。収束クラブの存在は、高所得・高ガバナンスの日本が特定の軌道を持つことを示唆し、共通の政策ではなく日本固有のエネルギー構成と移行政策を考慮する必要性を強調する。
In the global GX context
The study reinforces the heterogeneity in global energy transitions, challenging uniform policy frameworks. For GX practitioners, it highlights regime-dependent adjustment processes and the importance of structural factors such as governance quality, suggesting that decarbonization strategies must be context-specific.
👥 読者別の含意
🔬研究者:Provides a comprehensive convergence analysis framework that can be applied to other sustainability metrics.
🏢実務担当者:Suggests that corporate decarbonization strategies should account for the specific energy regime of their operating countries.
🏛政策担当者:Important evidence that uniform policies are insufficient; differentiated approaches based on country-specific convergence clubs are necessary.
📄 Abstract（原文）
This study investigates whether countries converge toward common long-run paths in renewable energy consumption and examines the implications for global fuel transition dynamics. Using a balanced panel of 108 countries over the period 1990–2022, we implement an integrated econometric framework that combines stochastic convergence tests, β- and σ-convergence analysis, the Phillips–Sul club convergence methodology, ordered logit modelling, and heterogeneous panel causality tests. The results reject global stochastic convergence, indicating that countries do not share a common transition trajectory. However, evidence of β- and σ-convergence suggests the presence of partial and bounded catch-up dynamics. The Phillips–Sul approach identifies four distinct convergence regimes, implying multiple steady-state equilibria in global energy systems. Structural analysis shows that income and governance quality increase the probability of belonging to higher-renewable-energy regimes, while carbon intensity constrains upward transitions. Regime-specific causality results further reveal that the drivers of renewable energy dynamics differ across structural contexts. Overall, the findings demonstrate that global energy transitions are characterized by persistent heterogeneity and regime-dependent adjustment processes rather than uniform convergence. This study contributes by integrating convergence analysis with structural modelling and regime-based interpretation, offering a more comprehensive framework for understanding differentiated decarbonization pathways. The results carry important policy implications, highlighting that effective energy transition strategies must be tailored to regime-specific conditions rather than relying on uniform policy approaches.
