Rare earth elements are essential raw materials that underpin strategic emerging industries,including those focused on new energy,advanced materials,and high-end technological innovation.Consequently,they have emerged as vital strategic mineral resources subject to global competition.In the context of the current wave of technological revolution and industrial transformation,the security of the rare earth supply chain is encountering unprecedented and complex challenges,largely due to its significant international geopolitical implications.A scholarly assessment of the resilience of the rare earth industrial chain aids in elucidating the existing impediments to the development of China’s rare earth industry and facilitates a comprehensive and precise understanding of its current resilience status.Utilizing pertinent data spanning from 2000 to 2022,this thesis develops an indicator system to measure the resilience of the rare earth industrial chain across four dimensions:Resistance,recovery,reorganization,and renewal capabilities.The entropy weight method was utilized for evaluation,and a subsequent analysis of the comprehensive resilience score was performed using the index obstacle degree model,the index contribution model,and the coupling coordination degree model.The results indicate that:(1) The resilience of China’s rare earth industrial chain exhibited an upward fluctuation from 2000 to 2022.(2) Prior to 2016,the primary impediment to resilience in the rare earth industry chain was the renewal capability,whereas post-2016,the resistance capability emerged as the predominant constraint.(3) The enhancement of resilience within the rare earth industrial chain is predominantly influenced by recovery and renewal capabilities.(4) Between 2000 and 2022,the coupling coordination level among various resilience indicators of the rare earth industrial chain has shown an upward trend,albeit remaining imbalanced.The findings of this study offer policy insights for strengthening the resilience of China’s rare earth industry chain,with recommendations for countermeasures at the enterprise,industry,and government levels.
中国稀土已形成从开采选矿、冶炼分离、材料制备、终端应用到循环回收的稳定产业链(方文龙等,2024)。作为金属矿产资源中的优势矿产,中国在稀土产业链上游的国际市场地位短期内虽然很难撼动,但是产业链下游企业开展技术“去稀土化”与美西方“去中国化”的产业链布局导向相互加持,共同推动形成全球稀土资源“双链”格局(杨丹辉等,2024)。稀土产业链各环节先进的开采、冶炼和应用技术,能够促进稀土上下游产业的绿色转型和应用升级,是推动稀土产业升级和可持续发展的关键(李文龙等,2018;赖丹等,2019;吴一丁等,2021;Zuo et al.,2021;赖丹等,2022;张琳等,2022)。周美静等(2023)从敏捷性、稳健性和依赖度3个维度构建了稀土供应链韧性评估指标体系,评估了境外国家(地区)的稀土供应链韧性。
