Metal resources are critical materials for Chinese economic development,and their security is closely related to national security. Here we systemically review the connotation and mechanisms,driving factors,evaluation methods,national strategies and policies of national metal resource security(NMRS). The content of NMRS covers the security of supply,price and environment. The key factors that influence the security status of NMRS are resource endowment,economic development,technical progress,and ecological environment. In principle,existing studies apply three approaches to assess the criticality of metals,criticality matrices,criticality indices and quantitative future supply and demand analysis. The most used approaches in metal demand forecasting are the trend extrapolation method,bottom-up approach and mathematical statistics. The market power and pricing of metals are estimated by the Herfindahl-Hirschman index,Lerner index,and equilibrium game models. Different strategies and policy tools for metal security are adopted by countries or regions depending on their national circumstances. Based on these findings and the needs of social development,future study in NMRS should focus mainly on the following four areas:(1)comprehensive research on the mechanism of NMRS;(2)the influence of new technological revolution on NMRS;(3)impacts of changing international trade rules and pricing mechanism on NMRS;and (4)evaluation of the impact of international significant strategies on NMRS.

Key words: national resource security, metal resources, content and mechanism, evaluation methods, strategy and policy
