    The material industry provides a material basis for national economic development, social progress, and national defense security. Materials are particularly important for China as it now enters the middle and late stage of industrialization. Conducting strategic research on new materials will help strengthen China’s manufacturing sector. In this article, we systematically analyze the development status, trend, and problems regarding the new material industry in China and abroad and summarize the domestic and foreign policies for the industry. After analyzing the future strategic demands for the new materials, we propose the overall idea, characteristics, and goals of the new material power strategy. The key direction of the strategy need to focus on fields such as advanced basic materials, key strategic materials, and frontier materials. An evaluation–characterization–standards platform should be established for new materials. Furthermore, we propose some policy suggestions to facilitate the development of China’s new material industry and provide a reference for the decision making by relevant government departments. Specifically, an independent innovation system for new materials should be constructed; platforms for digital R & D, production application demonstration, and resource sharing should also be established; the quality and technology infrastructure should be improved; and talent teams dedicated for the development of the new material industry should be created.

    Electronic ceramics are a type of new materials of strategic significance. They are the core materials of passive electronic components and an important technology frontier in the electronic information technology field. As the electronic information technology develops toward integration, intelligence, and miniaturization, passive electronic components have become a bottleneck restraining the development of electronic component technology. Therefore, the strategic position of electronic ceramic materials and their processing technologies is increasingly prominent. The field of electronic ceramic materials and components has formed a good industrial technology foundation in China. However, its competitiveness is still insufficient in high-end materials and components, and some key material, process, and equipment technologies are controlled by other countries. Facing the new situation, it is urgent to increase R & D investment, rationalize the system and mechanism, and strengthen the independence and innovation of the industrial chain.

    The quality infrastructure—with evaluation, characterization, and standards as its basic elements—plays an important role in supporting industrial transformation and upgrade, promoting technological innovation, improving production efficiency, ensuring product quality, and enhancing industrial international competitiveness. Meanwhile, the acceleration of new material innovations has expanded the scale of the industry and increased the types and supply of new materials, which proposes new requirements for the industrial quality infrastructure. In this article, we analyze the importance of evaluation, characterization, and standards for the development of the new materials industry and summarize the development status of the quality infrastructure in China. Currently, a technical system has been primarily formed for the new material industry in China and has greatly supported industrial innovation. China has also made progresses in internationalization in terms of assessment, characterization, and standardization of the new material industry. However, China’s quality infrastructure for new materials is still underdeveloped in terms of overall level and technological innovative ability in key areas; and its internationalization progress can hardly meet industrial requirements. Therefore, an assessment–characterization–standards platform is demonstrated and analyzed for the new material industry in China. Correspondingly, we suggest that the top-level design of the quality infrastructure should be strengthened, an “evaluation–characterization–standards” one-stop service mode promoted, independent brands developed regarding certification, testing, and standards, and administrative agencies encouraged to adopt the evaluation results.
