Research on the dynamic evolution path of the rare earth key technology in China ：Based on the technology group similarity timing analysis method

摘要:

稀土是全球重要战略资源,识别稀土产业关键技术动态演进路径,对于提升我国产业链供应链安全具有深远的意义。本文基于1985-2023年间我国稀土专利数据,采用系统聚类法将稀土技术发展划分为四个关键阶段,并通过多重测量中心度识别各阶段的共性技术,观察共性技术的演变趋势,在此基础上结合技术群相似度时序分析法探测我国稀土关键技术动态演进路径。研究发现:(1)整体来看,我国稀土技术领域取得了显著进步,创新主体集中于国有企业、科研机构以及高等院校；(2)从共性技术分析上,合金技术、建筑材料及磁性技术作为稀土领域的核心共性技术,贯穿了技术发展的全过程,并持续推动产业升级；(3)从演进路径上,我国稀土技术具有较强的关联性,技术融合和分化路径明确,涉及稀土功能材料开发、稀土冶炼分离技术以及稀土终端应用领域三条路径。

Abstract:

Rare earth is an important strategic resource in the world. Identifying the dynamic evolution path of key technologies of the rare earth industry is of far-reaching significance for improving the security of China"s industrial chain and supply chain. This paper is based on 1985-2023, the system clustering method of rare earth technology development is divided into four key stages, and through multiple measurement center to identify the common technology of various stages, observe the evolution trend of generic technology, on the basis of the technology group similarity timing analysis detection of rare earth key technology dynamic evolution path in China. The study found: (1) on the whole, China has made rare earth technology, the innovation subjects concentrated in state-owned enterprises, scientific research institutions and colleges and universities; (2) from the analysis of alloy technology, building materials and magnetic technology, as the core generic technology in the field of rare earth, through the whole process of technology development, and continue to promote industrial upgrading; (3) from the evolution path, China"s rare earth technology has strong correlation, clear path of technology integration and differentiation, involving the development of rare earth functional materials, rare earth smelting and separation technology and rare earth terminal application field.
