中国の低炭素都市パイロット（LCCP）制度が都市の炭素排出量に与える影響を、2011〜2023年の中部地域都市パネルデータと多期間DIDモデルで検証した。LCCPは排出量を有意に削減し、その効果は非資源都市と中小都市で顕著だが、資源都市・大都市では確認されなかった。エネルギー強度と財政自主性が競合的な媒介効果を示し、空間依存性はあるものの都市間の政策スピルオーバーは確認されなかった。
English
Using panel data from Central Chinese cities (2011–2023) and a multi-period DID model, this study finds that the Low-Carbon City Pilot (LCCP) program significantly reduces urban carbon emissions. Effects are stronger in non-resource-based and small/medium cities, while energy intensity and fiscal autonomy show competitive mediation. Spatial dependence exists, but no robust cross-city policy spillovers are found.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の低炭素都市政策の実証評価は、日本の自治体・地域脱炭素政策（地域脱炭素ロードマップ、再エネ促進区域）の設計に示唆を与える。特に、政策効果が都市の属性（資源依存度・規模）で異なる点は、日本国内の地域差を踏まえた政策立案に参考となる。
In the global GX context
This paper adds to the global empirical literature on subnational climate policy evaluation, relevant to debates on the effectiveness of city-level decarbonization programs. It highlights heterogeneous treatment effects and the role of fiscal capacity, offering lessons for policy design in other countries pursuing coordinated low-carbon transitions.

📄 Abstract（原文）
Against the backdrop of China’s “dual-carbon” goals, the low-carbon city pilot (LCCP) program has become an important policy instrument for promoting urban green and low-carbon transformation. Using panel data from cities in Central China over the period 2011–2023, this study employs a multi-period difference-in-differences (DID) model to examine the impact of the LCCP program on urban carbon emissions and its underlying mechanisms. The results show that the LCCP program significantly reduces urban carbon emissions, and this finding remains robust to a series of robustness checks. Mechanism analysis indicates that the LCCP program significantly increases technological innovation, although the corresponding indirect effect on carbon emissions is not statistically significant. By contrast, energy intensity and fiscal autonomy exhibit significant competitive mediation effects, suggesting that the policy’s direct emission reduction effect interacts with indirect transmission channels associated with energy efficiency and local fiscal resource allocation. Furthermore, the emission reduction effect of the LCCP program is more pronounced in non-resource-based cities and small- and medium-sized cities, while no statistically significant effect is observed in resource-based or large cities. Spatial econometric analysis reveals significant spatial dependence in urban carbon emissions. Although the LCCP policy generates a significant local emission reduction effect, no robust evidence of cross-city policy spillovers is identified. These findings provide empirical evidence for understanding the effectiveness and transmission mechanisms of low-carbon policies and offer useful insights for advancing differentiated and coordinated low-carbon development in Central China.
