China is currently the largest CO emitter in the world. Within China, more than 60% of CO emissions originate from high energy-intensive (HEI) industries. Therefore, controlling and reducing CO emissions from HEI industries is crucial if China is to achieve its 2030 emission reduction targets. This study aims to investigate regional differences in the impact of HEI industries on CO emissions in China. This paper presents an analysis of the impact of HEI industries on CO emissions at the national and regional levels using a modified STIRPAT model and provincial panel data from 2000 to 2015 in China. The results show that HEI industries are significant contributors to China's CO emissions owing to the growth in industries, coal-based energy structure, low level of technology, and outstanding conduction effects. The impact intensity of HEI industries on CO emissions decreases from the western to the central and eastern regions in China because of a huge regional difference in industrial structure, energy structure, R&D investment, and industrial transfer. Our findings have important implications for policymakers in China by indicating that regional policies concerning HEI industries should be differentiated to successfully reduce CO emissions and meet national targets.
中国目前是世界上最大的二氧化碳排放国。在中国，超过 60%的二氧化碳排放来自高能源密集型（HEI）产业。因此，如果中国要实现其 2030 年减排目标，控制和减少 HEI 产业的二氧化碳排放至关重要。本研究旨在调查中国 HEI 产业对二氧化碳排放的区域差异。本文利用改进的 STIRPAT 模型和中国 2000 年至 2015 年的省级面板数据，分析了 HEI 产业对中国国家和地区 CO 排放的影响。结果表明，由于工业增长、煤炭为主的能源结构、技术水平低和突出的传导效应，HEI 产业是中国 CO 排放的重要贡献者。由于产业结构、能源结构、研发投入和产业转移方面存在巨大的区域差异，HEI 产业对 CO 排放的影响强度从中国西部向中部和东部地区递减。我们的研究结果对中国政策制定者具有重要意义，表明针对 HEI 产业的区域政策应该有所区别，以成功减少 CO 排放并实现国家目标。
