Strategy & Policy Decision Research
Mineral resources are fundamental materials for economic and social development. Irrational exploration, utilization and consumption not only undermine the security of industrial chain and supply chain, but also seriously damage ecosystem. A new round of technological revolution and carbon neutral strategy is reshaping the global innovation distribution and technical structure. As China's economic and social development advances into post-epidemic stage, the supply and demand structure of strategic metal resources has experienced profound changes. The security challenges extend from traditional security of access to resource to the entire chains, including extraction, processing, use and recycling. China's solid waste generation has grown rapidly along with economic development, but its recycling rate is still low, leading to the loss of a large scale of resources. In the future, the collection and recycling system of secondary metals should be enhanced, management systems for classification and grading of resources and reserves of secondary resources should be established, and national systems and standards for efficient resources utilization should be developed. The above measures are designed to guarantee the optimal internal circularity and self-sufficiency of strategic metals resources, which helps alleviate the dependence on other countries.
