稀有矿产资源经济重要性评估

稀有矿产资源作为现代工业,尤其是战略性新兴产业的关键原材料,在国民经济中扮演着越来越重要的角色。本文在对18种稀有矿产资源界定的基础上,独立于矿种市场规模的大小、价格的高低,采用价值增值链的方法,根据稀有矿产资源的最终用途以及它们所流动部门的增加值来评估其对经济的重要性,同时,将资源替代纳入经济重要性的计算。计算结果表明:2016年我国稀有矿产锗、锆、铟、铍、稀土金属以及镉对经济重要性排序较为靠前,钴、石墨、钽、锂等次之,铌、铼则较为靠后。

Economic importance assessment of rare minerals

As a key raw material of modern industry, especially strategic emerging industries, rare mineral resources play an increasingly important role in the modern national economy. Based upon the classification on 18 kinds of rare minerals, this paper avoids the market scale and price of rare minerals, the value-added chain method is used to evaluate the economic importance of rare mineral resources according to the final use of mineral resources and the added value of the corresponding departments, at the same time, resource substitution is included in the calculation of economic importance. The results show that in 2016, the economic importance of germanium, zirconium, indium, beryllium, rare earth metals and cadmium ranked higher, followed by cobalt, graphite, tantalum and lithium, while niobium and rhenium ranked lower.
