Abstract

Interregional trade significantly drives PM2.5 pollution in regions exceeding China's air quality standards. While production‐based accounting ignores pollution transfers embodied in trade, conventional consumption‐based accounting (CBA) overlooks regional disparities in emission control. Using a Multi‐Regional Input‐Output model, this study applies a technology‐adjusted CBA (TCBA) to reassess China's air pollutant footprint and environmental‐economic inequality. Under TCBA, most of the affluent eastern provinces show notable footprint reductions, shifting from net emission importers to exporters due to their efforts on emission control. Conversely, less‐developed regions with lax controls show increased footprints. Regional inequality weakens under TCBA, with trade pairs showing absolute inequality dropping from 37% to 28%. Our study emphasizes the importance of acknowledging regional efforts on green production in future environment and climate governance.

对中国富裕省份空气污染泄漏的过度指责

区域间贸易显著推动了超过中国空气质量标准地区的PM2.5污染。以生产为基础的核算忽略了体现在贸易中的污染转移，而传统的以消费为基础的核算（CBA）忽略了排放控制方面的区域差异。本研究采用多区域投入产出模型，采用技术调整CBA （TCBA）重新评估中国的空气污染物足迹和环境经济不平等。在TCBA下，大多数富裕的东部省份表现出显著的碳足迹减少，由于他们在排放控制方面的努力，从净排放进口国转变为出口国。相反，管制宽松的欠发达地区的碳足迹增加。区域不平等在TCBA下减弱，贸易对显示绝对不平等的比例从37%降至28%。我们的研究强调了在未来环境和气候治理中承认区域绿色生产努力的重要性。
