Exploring the efficiency and technology related driving factors of China's industrial sulfur dioxide (SO) emission intensity change from a staged perspective is significant for reducing emissions in an efficient way. This study shows how efficiency and technology related factors at two stages, cleaner production and end-of-pipe treatment, influence changes in China's industrial SO emission intensity, by implementing a two-stage production-theoretical decomposition analysis (PDA) approach. The empirical research was conducted by decomposing changes in China's industrial SO emission intensity during 2011-2015. The results show that potential pollution intensity and treatment technological change substantially benefited the industrial SO emission intensity reduction, while changes in the treatment technical efficiency largely inhibited decreases in the industrial SO emission intensity. At the regional level, the decrease in industrial SO emission intensity created by production technological change occurred in the eastern and north-eastern regions, while this factor increased industrial SO emission intensity in the western and central regions. This study also found that changes in treatment technological change reduced industrial SO emission intensity in all four regions. Based on the decomposition results, this paper makes targeted policy recommendations for different levels of governments.
从分阶段的视角探讨中国工业二氧化硫（SO）排放强度变化的效率和技术相关驱动因素，对于以高效的方式减排具有重要意义。本研究通过实施两阶段生产理论分解分析（PDA）方法，展示了清洁生产和末端治理这两个阶段的效率和技术相关因素如何影响中国工业 SO 排放强度的变化。通过对 2011-2015 年中国工业 SO 排放强度变化进行分解，进行了实证研究。结果表明，潜在污染强度和处理技术变革极大地促进了工业 SO 排放强度的降低，而处理技术效率的变化则在很大程度上抑制了工业 SO 排放强度的降低。在区域层面上，生产技术变革导致了东部和东北地区工业 SO 排放强度的降低，而这一因素增加了西部地区和中部地区的工业 SO 排放强度。本研究还发现，处理技术变革的变化降低了所有四个地区的工业 SO 排放强度。基于分解结果，本文为不同级别的政府提出了有针对性的政策建议。
