日本語

中国268都市を2001〜2021年にわたり、集約化と低炭素性能の二軸で評価する二段階super-SBM手法を提示。集約化効率は低水準で変動し、低炭素効率はU字型を描き、いずれも東部が優位。268都市中146都市(54.48%)が低-低モードに留まり、高-高は53都市(19.78%)のみ。人口規模の大きい都市ほど持続可能性が高いことを示す。

English

A two-stage super-SBM framework evaluates urban construction land use efficiency across 268 Chinese cities (2001-2021) along intensification and low-carbon dimensions. Intensification efficiency stays low and fluctuates, while low-carbon efficiency follows a U-shape, with the eastern region leading both. 146 cities (54.48%) fall in a Low-Low mode versus only 53 (19.78%) in High-High; larger-population cities show stronger sustainability.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

都市計画・土地利用規制と炭素削減の両立を測る指標設計は、日本のコンパクトシティ政策や自治体の脱炭素計画策定の参考になる。ただし開示制度や企業実務との直接接点は薄い。

In the global GX context

Offers a replicable efficiency framework linking land-use intensification to decarbonization, relevant to urban climate policy and city-level emissions accounting debates. It does not engage TCFD/ISSB disclosure infrastructure directly.

🏛政策担当者:都市拡張と炭素削減を調整する差別化された土地利用政策の設計に、地域別効率データを活用できる。

📄 Abstract（原文）

Evaluating urban construction land use efficiency (UCLUE) from the dual perspectives of intensification and low-carbon performance is critical for sustainable urban development. Previous studies often assess this efficiency from a single perspective, failing to capture potential conflicts and synergies between economic density and emission reduction goals. This study adopts a two-stage super-SBM approach to evaluate UCLUE of 268 Chinese cities from 2001 to 2021, systematically examining both intensification and low-carbon dimensions. Results show that (1) the average efficiency from an intensification perspective remains relatively low and exhibits a fluctuating pattern of initial increase, subsequent decline, and final rebound, with the eastern region ranking highest, followed by the western and central regions. (2) The low-carbon efficiency follows a U-shaped trajectory over the study period, with the eastern region again performing best, followed by the western and central regions. (3) Many cities exhibit relatively low efficiency in both dimensions, with 146 of the 268 cities (54.48%) falling into the Low–Low development mode and only 53 cities (19.78%) achieving the High–High development mode. Furthermore, cities with larger population sizes demonstrate stronger sustainable performance. These findings provide empirical evidence for identifying spatial heterogeneities and formulating differentiated, context-specific land use policies to coordinate urban expansion and carbon reduction.
