MINT諸国（メキシコ・インドネシア・ナイジェリア・トルコ）を対象に、2008〜2021年の技術導入・経済グローバル化・電化が温室効果ガス排出に与える影響をMMQR等で分析。電化は化石燃料依存により排出を一貫して押し上げ、経済グローバル化は排出を収斂させるが中央値は動かさず、技術導入は上位分位で複合GHGを増やす一方、純CO2では符号が反転。EKC仮説は複合GHGで支持されるが純CO2では転換点未到達。
English
Using MMQR and robustness checks (FGLS, 2SLS), this study examines how technological adoption, economic globalization, and electrification shape GHG emissions in MINT economies (2008–2021). Electrification consistently raises emissions due to fossil-fuel power reliance; globalization compresses cross-country emissions without shifting medians; technology adoption raises composite GHGs at upper quantiles but turns negative for pure CO2. EKC holds for composite GHGs but not yet for CO2.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業がMINT諸国に製造拠点・サプライチェーンを持つ場合、進出先の電化・排出構造の理解はScope 3管理や移行計画に資する。ただし日本国内のSSBJ・有報対応への直接的示唆は乏しい。
In the global GX context
Adds emerging-market evidence to the EKC and decoupling literature, relevant to global transition finance debates on whether electrification alone decarbonizes without grid greening. Useful for ISSB/CSRD-aligned Scope 3 assessments of supply chains in MINT economies.
👥 読者別の含意
🔬研究者:MMQRによる分位別異質性分析の手法と、EKCの複合GHG対純CO2での乖離という実証的知見が参考になる。
🏢実務担当者:MINT諸国に拠点を持つ企業は、進出先の電化が排出増につながる構造を踏まえ、再生可能エネルギー調達やScope 3算定の前提を見直す材料になる。
🏛政策担当者:新興国での電化政策は電源構成の脱炭素化とセットで設計すべき、貿易協定への環境条項や所得連動型財政インセンティブがEKC転換点を早める可能性を示唆。
📄 Abstract（原文）
In the face of accelerating global warming, climate change poses existential risks to emerging economies, particularly the MINT nations (Mexico, Indonesia, Nigeria, Turkey), which face dual challenges of sustaining economic growth and mitigating environmental degradation. This study offers novel insights into the climate change dynamics of MINT economies by investigating the roles of technological adoption, economic globalization, and electrification in influencing greenhouse gas emissions over the period 2008–2021. Drawing on the Environmental Kuznets Curve (EKC) framework, the study leveraged on the Method of Moments Quantile Regression (MMQR) to uncover the heterogeneous effects across the central-emissions distribution. To ensure robustness and address endogeneity concerns, the Quantile Regression with block‑bootstrap, the Feasible Generalized Least Squares (FGLS) and the Two-Stage Least Squares (2SLS) estimations were conducted, with consistent results confirming that of the primary estimator. The results revealed that electrification consistently elevates emissions across all central quantiles, reflecting the continued reliance on fossil-fuel-based power generation. Economic globalization compresses cross-country emission, but does not significantly shift median emission levels, indicating its role in harmonizing, rather than reducing, environmental outcomes. Technological adoption exhibits a positive effect on composite greenhouse-gas emissions at upper quantiles but flips to a negative (albeit insignificant) sign for pure CO₂, suggesting nascent decarbonization benefits as clean-tech diffusion deepens. Consistent with the EKC hypothesis, GDP enters positively and GDP² negatively when using composite GHGs, whereas pure CO₂ emissions do not yet display an income turning point. Policy recommendations include renewable-focused electrification strategies, binding environmental provisions in trade agreements, and income-tied fiscal incentives to hasten the EKC turning point.
