摘要(Abstract)：

基于全球稀土资源的供需形势和中国稀土资源减少的趋势,运用系统动力学的模型来预测未来17年我国稀土资源储备量。选取了2000²013的生产和消费数据,通过定量模拟计算中国稀土供需差波动系数,设计了稀土资源供需差波动范围分别为0%,20%的两个方案,模拟计算了两个方案的年储备量、累计储备量和储备量绝对值。方案一范围是(-0%,+0%),仿真预测出稀土未来17年累积储备量为720551 t,即战略储备规模达到720551 t,该方案下不论供需差发生如何波动,国家都会进行储备或释放调节;方案二范围是(-20%,+20%),预测出未来17年战略储备规模为461331 t,国家只需在这个范围外进行收储释放调节,从而调节市场供求,降低价格波动幅度。本文从不同供需差的波动系数来模拟计算储备量,目的是为国家相关部门在进行稀土储备决策时提供参考,可以根据我国经济景气状况和供需形势,以及稀土产业发展状况,进行不同规模的稀土储备。
