基于系统动力学的钼资源战略储备规模研究

基于《中国矿产资源报告(2017)》的要求,为保证钼资源安全可持续地供应,对未来14a我国钼资源战略储备规模运用系统动力学模型进行模拟分析。主要选取供应和消费数据,综合考虑钼资源价格、钼资源供给量、钼资源需求量、储备成本以及出口收益对钼资源战略储备的影响,通过设定不同的经济发展情况,模拟计算钼资源入库量、累计入库量和储备量。结果表明:我国钼资源战略储备最大规模在经济高速增长时为847.60万t;经济平稳发展时为849.34万t;经济低速发展时为854.58万t。其次,不论经济形势如何变化,我国钼资源储备量总体来看呈先增多后减小的趋势,其峰值出现在2020年、2021年这2个时间点,并且政府部门都会进行收储或释放调节,以保证钼资源市场的稳定。
