中国260都市の2012〜2022年パネルデータを用い、都市拡散（US）が炭素排出強度（CEI）に与える影響と機序をパネル・調整効果・閾値効果モデルで検証。USのCEIへの効果は「U」字型で頑健であり、経済・生態レジリエンスと技術水準が高いほど抑制効果が強まる。経済レジリエンスは単一閾値、生態レジリエンスと技術水準は二重閾値を持ち、地域・都市規模で効果の形が異なる。
English
Using panel data from 260 Chinese cities (2012–2022), this study examines how urban sprawl (US) affects carbon emission intensity (CEI) via panel, moderation, and threshold models. The US–CEI relationship is U-shaped and robust; higher economic resilience, ecological resilience, and technological level strengthen the inhibitory effect. Single thresholds appear for economic resilience and dual thresholds for ecological resilience and technology, with heterogeneous effects across regions and city sizes.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の「双炭」目標下の都市政策研究であり、日本のGX文脈では都市計画・コンパクトシティ政策や自治体の脱炭素計画（地域脱炭素ロードマップ）との比較材料として参考になる。SSBJや有報開示とは直接の接点は薄い。
In the global GX context
Adds city-level empirical evidence on how urban form and resilience moderate carbon intensity, relevant to global debates on urban decarbonization pathways and just transition planning. It complements disclosure-focused work (TCFD/ISSB) by informing the physical and policy context in which corporate transition plans operate.

📄 Abstract（原文）
Urban sprawl (US) is an inevitable trend in the process of economic development, and achieving carbon neutrality is also an essential aspect of production reform. Therefore, reducing carbon emission intensity (CEI) in the US has become an urgent issue that needs to be addressed. Based on panel data from 260 Chinese cities between 2012 and 2022, this paper uses panel models, moderation effect models, and threshold effect models to examine the effect and mechanism of the US on CEI. The empirical results show that the effect of the US on CEI follows a “U” shape, which remains robust after various tests. The moderation effect indicates that the higher the urban economic resilience, ecological resilience, and technological level, the stronger the inhibitory effect of the US on CEI. The threshold effect analysis reveals that there is a single threshold for urban economic resilience, while dual thresholds exist for urban ecological resilience and technological level. Heterogeneity analysis shows that in the central-western regions and small and medium-sized cities, the effect of the US on CEI is “U” shaped, whereas in the eastern region and large cities, the effect follows an inverted “U” shape. The article aims to explore the realization of low-carbon goals in the US, particularly how macro-level regulation can enhance urban economic, ecological resilience, and technological levels to reduce CEI.
