中国の低炭素都市パイロット（LCCP）を外生的ショックとして、製造業企業の低炭素技術革新（LCTI）への因果効果を検証。結果はポーター仮説に反し、LCCPがLCTIを有意に抑制することを示す。LLMベースの二段階手法で気候政策不確実性指数を構築し、ボトムアップ型政策設計が不確実性を高め企業の革新意欲を削ぐことを確認。遵守コストがLCTI資金を圧迫する点も示す。
English
Using China's Low-carbon City Pilot (LCCP) as an exogenous shock, this study finds that voluntary carbon regulation significantly hinders corporate low-carbon technological innovation (LCTI), contradicting the Porter hypothesis. A two-stage LLM-based climate policy uncertainty index reveals that bottom-up policy design raises uncertainty and weakens firms' innovation incentives, while compliance costs crowd out LCTI funding.

日本のGX文脈において
日本ではSSBJ基準やカーボンプライシング議論が進む中、政策の予見可能性と企業の脱炭素投資インセンティブの関係を考える上で示唆的。特に自主的枠組みの設計次第でイノベーションが阻害され得る点は、国内のGX政策設計にも警鐘を鳴らす。
In the global GX context
This paper challenges the Porter hypothesis in the context of voluntary carbon regulation, offering critical evidence for global disclosure and climate policy design. It highlights how policy uncertainty and compliance costs can undermine corporate decarbonization innovation, relevant to ISSB/TCFD implementation and transition finance discussions.
👥 読者別の含意
🔬研究者:政策不確実性が企業の低炭素イノベーションに与える因果効果を、LLM活用の新指標で示した実証研究として参考になる。

🏛政策担当者:低炭素政策の設計において、安定した政策期待と強固な監督メカニズムの重要性を示す証拠として留意すべき。
📄 Abstract（原文）
Low-carbon technological innovation (LCTI) is crucial for decarbonization and global climate change mitigation. Taking China's Low-carbon City Pilot (LCCP)—a pioneering exploration for low-carbon development through policy innovation—as an exogenous policy shock, this study utilizes a staggered difference-in-difference-in-differences model and the data of China's manufacturing firms to examine the causality between the voluntary carbon regulation and LCTI. For the first time, the results indicate that the LCCP enactment significantly hinders corporate LCTI, contradicting the predictions of the Porter hypothesis. Mechanism analysis reveals that under the LCCP framework, local governments are authorized to design innovative policies tailored to their specific conditions and are responsible for their own assessment. Using a two-stage LLM-based approach to construct a climate policy uncertainty perception index, we confirm that this “bottom-up” approach introduces significant policy uncertainty faced by firms and weakens their motivation for LCTI involvement. Furthermore, the compliance costs associated with the policy crowd out the funds for LCTI, further hindering firms from engaging in LCTI. Heterogeneity analysis indicates that the adverse impact is more evident among firms exhibiting high risk aversion, ones with high artificial intelligence (AI) technology exposure, ones situated in non-resource-based cities, and state-owned ones, and that the adverse impact is significant for emission reduction technologies and zero-carbon technologies, but not for negative-carbon technologies. Additionally, all three pilot batches negatively impact corporate LCTI, suggesting that institutional modifications have not led to intended positive outcomes. This empirical research offers novel evidence regarding the efficacy of the LCCP and yields valuable policy insights—stable policy expectations and robust supervision mechanisms are crucial for achieving policy goals.
