日本語

中国の炭素排出権取引パイロット政策を自然実験とみなし、30省のパネルデータを用いた多期間DIDモデルで政策の炭素削減効果を検証。結果、政策は有意に排出を削減（係数-0.1701）し、東部・中部地域や人的資本の高い地域で効果が大きい。メカニズムとして市場・政府介入、技術革新投資、エネルギー消費削減・構造最適化を確認し、空間スピルオーバー効果も示した。

English

Using a quasi-natural experiment of China's carbon emissions trading pilot policy since 2013, this study employs a multi-period DID model on 30-province panel data. It finds significant emission reductions (coefficient -0.1701), with stronger effects in eastern/central regions and high human capital areas. Mechanisms include market and government intervention, technological innovation, and energy consumption optimization. Spatial spillover effects are also identified.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

中国ETSの実証分析は、日本におけるカーボンプライシング導入やGXリーグ等の政策設計に示唆を与える。特に、地域間の不均一な効果や空間スピルオーバーは、国内の地域別排出削減策を検討する際の参考となる。

In the global GX context

This empirical evidence from China's ETS pilots contributes to global carbon pricing literature, offering insights for countries designing or refining emissions trading systems. The heterogeneity and spillover findings are relevant for policy evaluation and international cooperation on carbon markets.

👥 読者別の含意

🔬研究者:Provides robust causal evidence on ETS effectiveness and mechanisms, useful for comparative carbon pricing research.

🏢実務担当者:Highlights how carbon pricing can drive innovation and energy optimization, informing corporate strategy under emerging carbon constraints.

🏛政策担当者:Offers empirical support for ETS as a mitigation tool, with insights on regional and human capital factors for policy design.

📄 Abstract（原文）

Carbon emissions trading market is an important institutional innovation to promote green and low-carbon transformation of economic development and sustainable economic and social development. With the quasi-natural experiment of China’s carbon emissions trading pilot policy since 2013, this paper constructs a multi-period double-difference model based on the panel data of 30 provinces and systematically evaluates the effectiveness as well as the heterogeneous performance of the carbon emissions trading policy on carbon emissions. The results show that the implementation of carbon emissions trading policy significantly reduces regional carbon emissions, with a significant impact coefficient of −0.1701 at the 1% level, and the finding passes a series of robustness tests. Heterogeneity analysis shows that the impact effect of carbon emissions trading policies is more significant in the eastern and central regions and more significant in regions with high levels of human capital. Mechanism analysis indicates that the carbon emissions trading policies achieve carbon emission reduction through the market mechanism and government intervention mechanism, and promote regional investment in scientific and technological innovation, reduce the total amount of energy consumption, and optimize the structure of energy consumption. Further analysis indicates that the carbon trading policy exerts a significant spatial spillover effect on carbon emission reduction.
