The synergistic abatement of air pollutants and CO emission in the industrial sector is crucial for China to achieve its energy conservation and emission reduction goals. However, none of the literature has conducted a systematic and in-depth research on assessing the synergistic abatement effect and identification of its driving factors for the industrial sector in China. Therefore, based on 36 industrial sub-sectors in China, we assess the synergistic effect of air pollutants on CO and examine the expansion mechanism of the synergistic effect. Furthermore, we explore how three driving factors, namely environmental regulation, technological progress and energy structure, affect the synergistic effect of abatement. The results indicate that, for the whole industrial sector, the synergistic effect of air pollutant abatement on CO reduction is significant, positively moderated by the enhancement of R&D investment, fixed asset investment and market openness. Strengthening environmental regulation, improving technological progress and optimizing energy structure could effectively promote the synergistic abatement effect. For three industrial subdivisions, the synergistic effect exists in three industrial categories, increasing R&D investment and fixed asset investment could positively moderate the synergistic effect. The three driving factors, environmental regulation, technological progress, and energy structure, could boost synergistic abatement for capital-intensive industries, but hardly for resource- and labor-intensive industries. In technology-intensive industries, only environmental regulation and technological progress could promote synergistic abatement. The findings could offer scientific support for the policymaking of the synergistic control of air pollutants emission and CO emission in China's industrial sector.
协同减少工业部门的空气污染物和 CO 排放对于中国实现节能减排目标至关重要。然而，目前尚无文献对中国工业部门协同减排效果进行系统深入的评估，也未识别其驱动因素。因此，本研究基于中国的 36 个工业子行业，评估了空气污染物对 CO 减排的协同效应，并检验了协同效应的扩展机制。此外，还探讨了环境规制、技术进步和能源结构这三个驱动因素如何影响减排协同效应。结果表明，对于整个工业部门而言，空气污染物减排对 CO 减排的协同效应显著，研发投入、固定资产投资和市场开放度的提高正向调节协同效应。加强环境规制、提高技术进步和优化能源结构可以有效促进协同减排效果。对于三个工业细分行业，协同效应存在于三个工业类别中，增加研发投入和固定资产投资可以正向调节协同效应。三个驱动因素，环境规制、技术进步和能源结构，可以促进资本密集型产业的协同减排，但对资源和劳动密集型产业的影响较小。在技术密集型产业中，只有环境规制和技术进步可以促进协同减排。研究结果可为中国工业部门协同控制空气污染物排放和 CO 排放的政策制定提供科学支持。
