アジア28カ国・2001〜2021年の動学パネル（System GMM）で、再エネ消費と所得格差の関係を分析。PCAで構築した制度品質指数が閾値的に作用し、統治が弱い国では再エネ普及が格差を拡大、制度が強い国では格差を縮小する。政策当局は環境目標と制度 reform を組み合わせる必要があると結論。
English
Using System GMM dynamic panel regressions across 28 Asian economies (2001-2021), this study examines how governance moderates the link between renewable energy consumption and income inequality. A PCA-based institutional quality index reveals a threshold effect: weak-governance countries see renewables widen inequality, while strong-governance countries see it narrow. The authors urge pairing green targets with institutional reform.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策（GX推進法・GX経済移行債）は公正な移行（just transition）を掲げるが、再エネ拡大が分配に与える影響を定量的に扱う国内研究は限られる。本稿は制度品質という条件を明示し、地域偏在や雇用転換を伴う国内の再エネ導入設計に示唆を与える。
In the global GX context
As ISSB/CSRD push transition-plan disclosure, this paper adds evidence that the social dimension of the energy transition is conditional on governance quality. It supports the global 'just transition' narrative by quantifying when renewables reduce rather than widen inequality, relevant to transition finance safeguards and EU taxonomy social criteria.

📄 Abstract（原文）
The transition toward renewable energy is often assumed to yield inclusive economic benefits, yet empirical evidence remains mixed. The purpose of this study is to examine the moderating influence of governance on the relationship between renewable energy consumption and income distribution across 28 Asian economies over the period from 2001 to 2021. The study employs a dynamic panel regression model using the System Generalized Method of Moments (GMM) estimator to address potential endogeneity problems and unobserved country-specific heterogeneity. Furthermore, a composite institutional quality index is constructed using principal component analysis to capture the multidimensional nature of governance. The findings demonstrate the critical influence of institutional quality on the correlation between renewable energy consumption and income inequality. In particular, in nations characterized by weak governance, the consumption of renewable energy correlates with increased income inequality, suggesting early-stage renewable investments may disproportionately benefit capital owners. However, in countries with stronger institutional frameworks, this relationship changes. When the quality of governance surpasses a certain median threshold, using renewable energy helps to close the income inequality gap. The practical implications of these results emphasize that policymakers should not rely solely on green energy to achieve equitable growth. Instead, governments must pair environmental targets with targeted institutional reforms, market entry facilitation, and regulatory transparency to ensure that the financial benefits of the energy transition are distributed fairly among all populations.
