钢铁行业是我国主要的能源消费及CO₂排放行业,推动钢铁行业低碳绿色发展已成为实现我国碳达峰、碳中和的重要环节。为此,研究围绕能源结构调整、工艺结构优化、节能减排技术推广和CCUS技术应用4方面,通过设置基础情景、稳定发展情景和强化减排情景3类情景,利用边际减排成本曲线对我国钢铁行业34项减排技术的减排成本和减排潜力进行分析。结果表明:在稳定发展情景下,我国钢铁行业平均减排成本为433元/tCO₂,所有技术的总减排成本为2100亿元,总减排潜力为4.9亿t。在各项减排技术中,废铁-电弧炉炼钢具有较高的减排经济效益,其以较低的单位减排成本贡献了钢铁行业近50%的碳减排量。未来,我国应加快推进长流程炼钢向短流程炼钢的发展,推动钢铁行业生产工艺的结构性调整。     

Low-carbon transition of iron and steel industry in China: Carbon intensity,economic growth and policy intervention

As the biggest iron and steel producer in the world and one of the highest CO2 emission sectors, China’s iron and steel industry is undergoing a low-carbon transition accompanied by remarkable technological progress and investment adjustment, in response to the macroeconomic climate and policy intervention. Many drivers of the CO2 emissions of the iron and steel industry have been explored, but the relationships between CO2 abatement,investment and technological expenditure, and their connections with the economic growth and governmental policies in China, have not been conjointly and empirically examined. We proposed a concise conceptual model and an econometric model to investigate this crucial question. The results of regression, Granger causality test and impulse response analysis indicated that technological expenditure can significantly reduce CO2 emissions, and that investment expansion showed a negative impact on CO2 emission reduction. It was also argued with empirical evidence that a good economic situation favored CO2 abatement in China’s iron and steel industry, while achieving CO2 emission reduction in this industrial sector did not necessarily threaten economic growth.This shed light on the dispute over balancing emission cutting and economic growth.Regarding the policy aspects, the year 2000 was found to be an important turning point for policy evolution and the development of the iron and steel industry in China. The subsequent command and control policies had a significant, positive effect on CO2 abatement.

基于情景分析的钢铁工业物质流与价值流协调性研究

本文基于情景分析理论和方法,建立了钢铁工业物质流与价值流协调度模型,对未来一段时期钢铁工业的协调发展状况进行研究.在维持现有发展模式的基准情景下,我国钢铁工业协调发展度将持续下降,2020年将下降到0.73.在环境恶化和经济效益相对脱钩的情景下,直到2020年我国钢铁工业协调发展度将维持在0.85的水平.而在经济与环境出现绝对脱钩的情景下,我国钢铁工业协调发展度将持续上升,2020年将达到0.95的高水平.因此,近期我国钢铁工业应遵循“基准相对脱钩绝对脱钩”的发展路径,降低总物质投入和污染物排放总量,提升经济产出效益,可持续发展才有可能实现.
