中国都市の2011〜2023年パネルデータを用い、正式環境規制（FER）と非正式環境規制（IER）がグリーンイノベーション（GI）に与える異質な効果を比較した研究。FERはGIを促進する一方、IERはU字関係を示す。気候政策不確実性はFERの正効果を弱めIERの抑制効果を強め、物理的気候リスクが閾値を超えるとFERの正効果は減衰する。地域・発展段階・資源賦存により効果は異なる。
English
Using Chinese city panel data (2011–2023), this study compares how formal (FER) and informal (IER) environmental regulation affect green innovation (GI). FER promotes GI while IER shows a U-shaped relationship. Climate policy uncertainty weakens FER's positive effect and strengthens IER's inhibitory effect, and FER's benefit declines once physical climate risk exceeds a threshold. Effects vary by region, development level, and resource endowment.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の都市レベル実証だが、規制の形式差と気候政策不確実性がイノベーション誘因をどう変えるかは、日本企業の脱炭素投資判断や政策設計（カーボンプライシング導入議論）にも示唆を与える。SSBJ開示とは直接の接点は薄い。
In the global GX context
Adds empirical nuance to the policy-mix literature by showing that climate policy uncertainty and physical risk condition the innovation response to regulation—relevant to debates on carbon pricing design and transition policy credibility under TCFD/ISSB-aligned risk disclosure.
👥 読者別の含意
🔬研究者:Provides a unified framework comparing formal vs. informal regulation with moderation and threshold effects of climate policy uncertainty and physical risk.
🏢実務担当者:Suggests that policy uncertainty can blunt the innovation upside of compliance-driven regulation, informing scenario planning for green capex.
🏛政策担当者:Highlights the need for stable, credible climate policy to preserve the innovation incentives of formal regulation, especially under rising physical risk.
📄 Abstract（原文）
As global carbon neutrality targets continue to advance, countries are increasingly investing in green technology innovation to balance economic development and environmental protection. Green innovation (GI) has therefore become a key priority for regions pursuing sustainable development. While existing studies have examined individual environmental regulations in isolation, few studies have compared their heterogeneous effects within a unified analytical framework. Furthermore, the moderating and threshold effects of climate-related external shocks remain insufficiently explored. To address these gaps, this study uses panel data from Chinese cities between 2011 and 2023 to examine the differential effects of formal environmental regulation (FER) and informal environmental regulation (IER) on GI. Moderation and threshold models are employed to investigate the roles of climate policy uncertainty(CPU) and physical climate risk. The results show that: (1) FER significantly promotes GI, whereas IER exhibits a U-shaped relationship with GI; (2) climate policy uncertainty weakens the positive effect of FER on GI and strengthens the inhibitory effect of IER on GI; (3) the positive effect of FER on GI declines after physical climate risk exceeds the identified threshold values; and (4) the effects of FER and IER vary across regions, development levels, and resource availability.
