本研究はナイジェリアを対象に、金融発展と経済成長が環境持続可能性に与える分布的影响を分位点ARDLモデルで分析。金融発展はCO2排出と生態学的フットプリントを悪化させ、特に中・高量子で影響が強い。経済成長は環境クズネッツ曲線仮説を支持するが、転換点は高量子でのみ確認。非対称性と分布性が示唆され、グリーンファイナンスや低炭素セクターへの政策を提言。
English
This study examines the distributional impact of financial development and economic growth on environmental sustainability in Nigeria using a quantile ARDL model. Financial development significantly worsens CO2 emissions and ecological footprints, especially at middle and upper quantiles. Economic growth supports the Environmental Kuznets Curve hypothesis, but the turning point occurs only at upper quantiles. Asymmetry and distributional effects are confirmed, recommending green finance and low-carbon policies.

日本のGX文脈において
ナイジェリアの事例ではあるが、金融発展と環境負荷の関係を分位点分析で捉えた手法は、日本の地域別・産業別の環境影響評価に応用可能。また、グリーンファイナンス促進策は日本のGX実現に向けた金融政策の参考になる。
In the global GX context
While focused on Nigeria, the study's quantile-based approach to financial development's environmental impact offers methodological insights for distributional analysis in other contexts. The policy recommendations on green finance and low-carbon economic restructuring align with global transition finance discussions, though the specific EKC findings are context-dependent.

📄 Abstract（原文）
This study investigates the distributional influence of financial development and economic growth on environmental sustainability in Nigeria. The study utlilized the novel quantile-based autoregressive distributed lag (QARDL) model. The findings reveal several critical insights: First, financial development significantly deteriorates environmental quality in both the short and long term, as evidenced by its positive impact on CO₂ emissions and ecological footprints across most quantiles—particularly at middle and upper quantiles where the effect intensifies. This confirms the distributional nature of financial development’s environmental impact, indicating that economic expansion through financial deepening has been accompanied by higher environmental costs. Second, the findings on economic growth support the Environmental Kuznets Curve (EKC) hypothesis, showing that environmental degradation initially rises with growth but eventually declines at higher levels of income. This transition point, however, appears to occur only at upper quantiles, suggesting that Nigeria is still in the earlier stages of the EKC trajectory Third, the findings support the presence of asymmetry in the growth-finance-environmental quality relationship and underscore the distributional nature of the relationship across different environmental states. The study recommends the introduction of environmental risk assessments and sustainability criteria in financial sector lending and investment decisions and incentivise green financing products such as renewable energy loans, sustainable infrastructure bonds, etc. Also, government should channel economic growth toward sectors with lower carbon intensity through targeted tax incentives and subsidies.
