Rare earth is an important strategic mineral resource for national economy and national security. As the largest producer and exporter of rare earth, China's rare earth industry has problems associated with excessive production, mismatched pricing power and environmental pollution. Therefore, an in-depth study of the rare earth industry security is necessary. Based on proposed definition for mineral resource security, this paper established a rare earth resource security evaluation model based on the "driver-pressure-state-impact-response" conceptual model using an extended TODIM (an acronym in Portuguese for interactive and multi-criteria decision-making) method combined with the E-DEMATEL (entropy and decision-making trial and evaluation laboratory) method. The model was then applied to Chinese rare earth data from 2006-2015 to assess the security, from which it was found that while the security level was not high, the overall trend was improving. Moreover, some critical response factors affecting REEs (rare earth elements) security are identified, including tariffs, research investment, etc. This paper not only introduces a new evaluation of REEs security but also explores the crucial indicators and the response mechanism.
稀土是国民经济和国家安全的重要战略矿产资源。作为全球最大的稀土生产国和出口国，中国的稀土产业存在产能过剩、定价权不匹配和环境污染等问题。因此，深入研究稀土产业安全问题十分必要。本文基于矿产资源安全的定义，提出了一个基于“驱动力-压力-状态-影响-响应”概念模型的稀土资源安全评价模型，采用扩展的 TODIM（葡萄牙语“交互多准则决策”的缩写）方法与 E-DEMATEL（熵和决策试验与评价实验室）方法相结合，对中国 2006-2015 年的稀土数据进行了安全性评估，结果表明，虽然安全水平不高，但总体呈上升趋势。此外，还确定了一些影响稀土安全的关键响应因素，包括关税、研究投资等。本文不仅介绍了一种新的稀土安全评估方法，还探讨了关键指标和响应机制。
