Evaluation And Analysis Of Rare Earth Safety In China Based On PSR Model

With the deepening of the reform and opening up, China in the international political and economic status of each show, are no longer just the military security, national security strategic mineral resources security has become an important part of national security. Rare earth as a kind of strategic mineral resources, the importance of constantly emerging, paper by building a model to analyze and evaluate the safety of the rare earth resources in our country. First reference to the international organization for economic cooperation and development (OPEC) proposed by the PSR model, established the safety assessment of PSR model of rare earths, causal analysis as the logical starting points, by rare earth safe pressure, state and response of three indicators, the indicators in the various relevant factors are analyzed. In rare earth pressure index of the safety evaluation is an important part of supply and demand analysis, so the paper using the grey forecasting GM (1.1) to predict the future supply and demand situation of rare earth; In pressure index, the paper using the reserve-production ratio, external dependency and scarcity index to analyze the status quo of China’s rare earth. Through analyzing the data of the indicators in model and forecasting, found that the scarcity of rare earth resources in China is more than one, and the next few years can not only meet our needs, but also a large number of exports. So the author believes that the protection of superior resources of rare earth point is:first of all, from the source control mining form and scale, secondly to improve the export policy, again is rare earth value return key to raise the level of technology of rare earth products.
