The distribution of global rare earth elements (REEs) resources and comparative advantages in exploitation and utilization of REEs are analyzed based on literature research and empirical research. It is pointed out that the global rare earth sector is currently confronted with a competition pattern in which global industrial chains are dominated by China and the United States. The competitiveness of rare earth industrial chain lies not only in reserves, but more importantly in the production, processing and utilization of resources, as well as in its role in boosting the industry's added value in the national industrial system. In terms of resources, in consideration of heavy dependence on external import of medium and heavy REE resources, without advantages such as in light REEs, China should not only strengthen the security assurance of medium and heavy REEs, implement the strategic mineral reserve system, but also make good use of domestic and international medium and heavy REE resources and actively strive for the rights and interests of international mineral resources. In terms of industrial policies, China should continuously implement favorable policies for its domestic rare earth industry, to maintain the global competitive advantages in rare earth industrial chain and industrial clusters, and avoid shifts of its rare earth industry and transfer of related technologies abroad.
