摘要
采用动态规划法,研究2014—2020年中国稀土战略储备的最佳储存量。结果表明,若中国国内市场上有稀土采集行为,随着时间的变化,我国的稀土最优储备规模在不断增加,但增加的速度是不一致的;稀土供应中断比例会影响稀土的储备量,随着稀土供给中断比例的增加,最佳存储速度也相应增加;稀土需求弹性值会影响稀土的最佳储存规模。针对以上结论提出了构建稀土资源储备法律制度,对不同稀土品种确立合理的储备方式,为稀土资源储备提供资金保障,加强稀土的研究与技术开发等实现路径。
This paper uses dynamic planning to study China's rare-earth metal strategic reserve in 2012--2020. Mining rare-earth metal in China's market leads to an increased rare-earth metal reserve, but at variable rate as time goes by. An interrupt of rare-earth metal supply will cast impacts on rare-earth metal reserve, which shall be raised at rate with a rising interrupt. A flexible demand of rare-earth metal also is related to the optimal rare-earth metal reserve. This paper proposes to set up laws on rare-earth metal reserve, different rare-earth metal with different reserve means, to provide a capital guarantee and to intensify technical research and development.
