アフリカ18カ国の2000～2020年のパネルデータを用いて、炭素価格が排出削減効果を持つのは一定の所得しきい値を超えた経済に限られることを発見。技術導入は逆に排出を増加させ、都市化と生物多様性保全は一貫して排出削減に寄与する。政策は国ごとの所得水準や制度能力に応じて差別化すべきと提言。
English
Using panel data from 18 African nations (2000–2020), this study finds that carbon pricing only reduces emissions above a GDP per capita threshold, technology adoption paradoxically increases emissions, while urbanization and biodiversity conservation consistently lower emissions. It calls for differentiated policy frameworks tailored to national income levels and institutional capacity rather than uniform regional approaches.

📄 Abstract（原文）
Environmental tax effectiveness in Africa is neither universal nor linear. It operates only above a critical income threshold, technology adoption paradoxically raises rather than reduces emissions, and policy responsiveness varies so dramatically across countries and emission levels that uniform regional frameworks prove inadequate. Drawing on panel data from 18 African nations over 2000–2020, this study deploys complementary multi-method estimation to capture structural breaks, cross-national heterogeneity, and distributional variation in emissions dynamics. The results establish that carbon pricing generates meaningful emission reductions exclusively among economies surpassing an identifiable GDP per capita threshold, where institutional prerequisites for effective tax enforcement are sufficiently developed. Technological adoption consistently increases emissions across the sample, driven by dependence on imported carbon-intensive industrial equipment, weak indigenous innovation systems, and inadequate complementary infrastructure rather than green technological progress. Urbanization, by contrast, emerges as a robust and broadly effective mitigation lever, with emission-reducing effects that deepen as urban systems mature. Biodiversity conservation demonstrates the most consistent suppressive effect on emissions across all estimation approaches and country contexts. These findings collectively call for differentiated policy frameworks calibrated to national income levels, institutional capacity, and emission profiles rather than continent-wide prescriptions.
