EU30カ国・2000〜2020年のパネルデータを用い、環境政策の厳格性指数（EPSI）が気候緩和技術（CMM）への公的R&Dとベンチャーキャピタル投資をどう媒介するかを分位点回帰で分析。EPSIは公的R&Dを通じ全分位で正の媒介効果を持つ一方、VC経由では10〜80分位で負の媒介効果が観察された。COP28目標に整合し、持続可能技術へのVC投資を促す政策枠組み拡充の必要性を示す。
English
Using panel quantile regression on 30 EU countries (2000-2020), the study examines how environmental policy stringency (EPSI) mediates public R&D and venture capital investment in climate mitigation technologies. EPSI shows a positive mediating effect via public R&D across all quantiles, but a negative mediating effect via venture capital from the 10th to 80th quantiles. The authors argue for expanded policy frameworks to incentivize VC investment in sustainable technologies, aligning with COP28 goals.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
EUの環境政策と気候技術投資の関係を実証する点は、日本でもグリーンイノベーション基金やGX経済移行債による公的R&D・民間投資の設計を考える上で示唆に富む。政策の厳格化がVC投資をむしろ抑制しうるという知見は、日本版GX政策のインセンティブ設計に一考の余地を与える。
In the global GX context
The paper contributes to global climate-finance scholarship by empirically testing how policy stringency shapes both public R&D and private venture capital for mitigation—directly relevant to debates on transition finance and blended finance under COP28/Paris alignment. Its finding that stringent policy can crowd out VC offers a cautionary counterpoint to assumptions that regulation automatically mobilizes private capital.
👥 読者別の含意
🔬研究者:政策厳格性が公的R&DとVCに非対称に作用する媒介構造を、分位点回帰で示した実証手法と結果が参考になる。
🏢実務担当者:環境規制の強化が調達・投資環境に与える影響を読み解く材料となり、気候技術投資の資金調達戦略検討に資する。
🏛政策担当者:政策厳格化がVC投資を抑制しうる点を踏まえ、公的R&Dと民間資金のインセンティブ設計を分けて考える必要がある。
📄 Abstract（原文）
ABSTRACT The integration between economic development and climate change holds significant importance for European Union (EU) countries due to their stage in the development process and the climate challenges they encounter. This study examines the intermediating role of environmental policies in climate change mitigation within the context of COP28's global climate objectives. Specifically, the study investigates the environmental policy stringency index (EPSI) as a mediator in promoting climate change mitigation technologies (CMM), focusing on public sector research and development (R&D) and venture capital investments. This study also considers economic growth, trade openness, FDI, and green technology diffusion (GTD), analyzing data from 30 EU countries between 2000 and 2020. Utilizing the panel quantile regression method, the findings reveal a positive intermediating effect of EPS on public R&D across all quantiles, while a negative intermediating effect of EPS on climate change mitigation through venture capital is observed from the 10th to the 80th quantiles. These results underscore the necessity of expanding environmental policies to foster incentives and supportive frameworks that encourage venture capital investments in sustainable technologies while increasing public R&D funding. Aligning with COP28 goals, this study highlights the pivotal role of robust environmental policies in accelerating the EU's transition toward climate neutrality.
