对中国、美国、日本、欧洲等的稀土在各领域内消费量的长时间序列数据变化,进行了定量分析,研究了世界稀土需求的变化趋势.对稀土新材料领域和传统领域中的应用进行了定性研究分析.通过定量定性研究得出了世界稀土消费量变化趋势和稀土应用的重点增长领域.由于稀土在不同领域的需求量变化,世界稀土终端消费领域不平衡格局将加剧,将导致稀土元素应用的进一步不平衡.
In this paper the varieties of global rare earth consumption were quantitatively studied and analyzed.And the varieties of applications of rare earth in both the new materials field and traditional application domain were also qualitatively analyzed.The global rare earth consumption trend and the major increasing consumption flled were obtained based on the quantitative and qualitative analysis.The consumption imbalance of different rare earth elements in different terminal consumption areas will be becoming greater for the varying of the rare earth demand.
