本論文は、長江デルタ（YRD）地域統合が都市のグリーン低炭素発展（GLD）効率に与える影響を、マルチ期間DIDモデルを用いて実証分析した。結果、YRD地域統合はGLD効率を有意に向上させ、その効果はエネルギー消費構造の最適化、産業構造の再編、政府のGLDへの関心向上、グリーンイノベーションの促進を通じて発現する。大都市や核心都市では効果が顕著だが、中規模都市や安徽省の都市では短期的には効果が見られない。長江経済帯や中国全土のGLD促進に政策的示唆を与える。
English
This study empirically examines the impact of Yangtze River Delta (YRD) regional integration on the green and low-carbon development (GLD) efficiency of cities using a multi-period DID model. Results show that YRD integration significantly improves GLD efficiency, primarily through optimizing energy consumption structure, promoting industrial restructuring, increasing government attention to GLD, and enhancing green innovation. The effect is stronger for megacities and core cities like Shanghai, while medium-sized cities and Anhui Province show no short-term effects. Findings provide policy insights for leveraging integration to promote GLD in the Yangtze River Economic Belt and beyond.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも、関東圏・関西圏などの広域連携がカーボンニュートラルに与える影響が注目されている。本論文のDID分析手法とメカニズム検証は、日本の地域統合政策（例: 首都圏・近畿圏の連携）のGLD効果を評価する際の参考となる。ただし、中国固有の制度とデータに基づくため、直接適用には調整が必要。
In the global GX context
This paper provides a rigorous empirical framework for evaluating how regional integration policies affect city-level decarbonization. It is globally relevant as many regions (e.g., EU, US, Japan) pursue similar coordination. The mechanism analysis—energy mix, industrial structure, policy attention, innovation—is transferable. However, the context is China-specific, so extrapolation requires caution.

📄 Abstract（原文）
Regional integration is a foundation for coordinated regional development and an important pathway for promoting the green and low-carbon development (GLD) (In this paper, GLD refers to green and low-carbon development, while YRD refers to the Yangtze River Delta) of cities. Based on a systematic analysis of the theoretical mechanisms through which regional integration affects the GLD of cities, this study uses changes in the spatial scope of Yangtze River Delta (YRD) regional integration as a quasi-natural experiment and constructs a multi-period DID model to examine its impact. The results show that YRD regional integration significantly improves the GLD efficiency of cities. This conclusion remains valid after a series of robustness tests, including the parallel-trends test, year-by-year PSM-DID, and modern staggered DID estimators. The heterogeneity analysis shows that the promoting effect of regional integration is more significant for megacities, core cities, and especially Shanghai, while its effects on medium-sized cities and cities in Anhui Province have not yet emerged in the short term. The mechanism tests further show that YRD regional integration improves the GLD efficiency of cities mainly by optimizing the energy consumption structure, promoting industrial restructuring, enhancing government attention to GLD, and improving green innovation. The findings provide useful empirical insights for fully leveraging the green and low-carbon effects of YRD regional integration and for promoting GLD in the Yangtze River Economic Belt and even across China.
