摘要:

为推动循环经济加快转型升级,评估钢铁产业链“资源-经济-环境”耦合对实现可持续发展具有积极意义。本文基于生命周期评估和能值核算构建了耦合系统模型,从产品、企业、行业层面分析了中国钢铁产业链耦合机制,结合废钢回收率讨论并识别了影响各层面主体耦合的关键驱动政策,以期为行业管理者提供参考依据。结果表明:①中国钢铁产业链主体的耦合协调度具有明显差异,总体呈现下游>中游>上游的分布规律;②资源-经济-环境系统中影响产业链耦合的主导因素是资源-经济维度;③随着废钢回收率的显著提高,“去产能”“技术进步”“提高资源利用率”政策可对钢铁产业链不同类别主体的耦合产生积极影响。为提高中国钢铁产业链韧性及抗风险能力,本研究从多类别主体角度为产业链综合发展提出有针对性的政策建议。

Abstract:

To accelerate the transformation and upgrading of industries and promote circular economy, evaluating the sustainability of steel industrial chain has a positive significance for the development of the industry. This study constructed a resource-economic-environment system coupling model based on life cycle assessment and energy accounting. It analyzed the coupling mechanism of China’s steel industrial chain at the product, enterprise, and industry levels, and identified the key driving policies affecting the coupling at different levels by considering the scrap steel recycling rate, which could provide a reference for industry managers. The results show that: The coupling coordination degree of China’s steel industrial chain subjects is significantly different, and generally presents the pattern of downstream > midstream > upstream. The resource-economic dimensions are the dominant factors affecting the coupling of industrial chain in the resource-economic-environment systems. With the significant increase of scrap steel recycling rate, the policies of “reducing capacity”, “technological progress”, and “improving resource utilization” can have a positive impact on the coupling of different types of subjects in the steel industrial chain. To improve the resilience and risk-resistance ability of China’s steel industrial chain, this study put forward targeted policy recommendations for the comprehensive development of the industrial chain from the perspective of different types of subjects.
