本研究は、経済・人口・空間の3次元の都市化を組み込んだ修正カーボンバランス（MCB）枠組みを構築し、中国366都市のカーボンバランスを分析。20年間で人為的排出と生態系吸収のギャップが拡大し、排出量の年平均増加率15.4%に対し吸収量は1%にとどまった。カーボンクォータ配分に補償的規制を導入すると、MCBを満たす都市が207から231に増加することを示した。
English
This study constructs a multi-dimensional modified carbon balance (MCB) framework incorporating economic, population, and spatial urbanization, analyzing 366 Chinese cities over 20 years. Results show a widening gap between anthropogenic emissions (15.4% annual growth) and ecological sequestration (1% growth). Introducing compensatory carbon quota allocation increases the number of cities meeting MCB from 207 to 231, providing a fairer assessment of low-carbon development.

📄 Abstract（原文）
Abstract Low‐carbon sustainable development has become essential for China to achieve its carbon neutrality goals. However, most existing carbon balance (CB) studies overlook carbon quota allocation that reflects development needs during urbanization, leading to assessments of urban low‐carbon development that may lack scientific rigour and fairness. This study integrates the three dimensions of economic urbanization, population urbanization, and spatial urbanization to construct a multi‐dimensional urban modified carbon balance (MCB) assessment framework and systematically calculates the CB and MCB of 366 cities in China. The results show that over the past 20 years, the gap between anthropogenic carbon emissions and ecological sequestration has continued to widen. Urban areas, accounting for the majority of emissions, exhibited an average annual emission growth rate of 15.4%, which contrasts sharply with the mere 1% average annual expansion observed in natural carbon sequestration capacity. The number of cities achieving CB decreased from 146 to 64. In addition, urban carbon quota demand was significantly correlated with multi‐dimensional urbanization levels. Under a carbon quota allocation mechanism that incorporates compensatory regulation, the number of cities meeting the MCB standard will increase significantly from 207 to 231. This study provides a fairer reference for assessing low‐carbon development in cities.
