中国の低炭素都市パイロット政策（LCCPP）が都市の炭素生産性に与える影響を、2007〜2023年の276都市のパネルデータと多重期間差分の差（DID）モデルで検証。政策は炭素生産性を有意に向上させ、その経路としてグリーン技術革新と経済集積の促進が示唆される。先進都市・革新都市・高排出都市・環境重視都市で効果が顕著であり、環境規制の厳格さが効果を強化する。
English
This study evaluates China's Low-Carbon City Pilot Policy (LCCPP) using a multi-period difference-in-differences model covering 276 Chinese cities from 2007 to 2023. The results show that LCCPP significantly improves urban carbon productivity, with green innovation and economic agglomeration as key mechanisms. Effects are stronger in developed, innovation-active, high-emission, and environmentally prioritized cities, and stricter environmental regulations amplify the policy's effectiveness.

日本のGX文脈において
本稿は中国の政策評価だが、DIDによる因果推論と、都市レベルでの脱炭素政策の効果条件（都市特性・規制環境）を示す点で、日本のGX推進や地域脱炭素戦略の設計に参考になる。特にSSBJ開示や投資家対応で必要となる政策効果の実証的知見を提供する。
In the global GX context
This paper contributes to global GX scholarship by providing causal evidence on place-based low-carbon policies. It offers insights for countries designing urban decarbonization strategies, emphasizing the roles of green innovation and economic agglomeration, and how policy effectiveness varies with local conditions and regulatory stringency.
👥 読者別の含意
🔬研究者:Useful for understanding causal evaluation methods (multi-period DID) and mechanisms of low-carbon city policies at the urban scale.
🏢実務担当者:Local governments and urban planners can leverage insights on which city types benefit most from low-carbon pilots and how to tailor strategies.
🏛政策担当者:Provides evidence that low-carbon city policies improve carbon productivity, with heterogeneous effects that support differentiated policy design and stricter regulation.
📄 Abstract（原文）
To advance its green and low-carbon transition, China has implemented the Low-Carbon City Pilot Policy (LCCPP) as a strategic initiative. A critical question remains unanswered on whether this policy effectively improves urban carbon productivity and facilitates the decoupling of economic growth from carbon emissions. Using the phased expansion of the LCCPP across Chinese cities as a quasi-natural experiment, this study constructs a multi-period difference-in-differences (DID) model based on a panel dataset of 276 prefecture-level and above cities from 2007 to 2023. The empirical results show that the LCCPP significantly enhances urban carbon productivity in pilot cities relative to non-pilot counterparts. This finding remains robust across a series of sensitivity checks. Mechanism analysis provides suggestive evidence that the policy may operate through two primary channels: fostering green technological innovation and promoting economic agglomeration. Heterogeneity analysis indicates that the policy’s positive effects are more marked in developed cities, innovation-active cities, high-carbon-emission cities, and environmentally prioritized cities. Furthermore, moderation analysis demonstrates that stricter environmental regulations strengthen the policy’s effectiveness. These findings provide empirical evidence for optimizing the design of low-carbon policies and offer actionable insights for tailoring green urban transformation strategies to local conditions.
