On the afternoon of September 22, 2025, Tracking the Cutting-edge Hotspots in Key Scientific and Technological Fields (2025) Released at the 18th Pujiang Innovation Forum, a joint research outcome of the Institute of Scientific and Technical Information of China (ISTIC) and the Shanghai Institute for Science of Science (SISS), was officially released at the Outcomes Release Conference of the 18th Pujiang Innovation Forum. Zheng Jia, Director of the Regional Development and Enterprise Innovation Research Center at ISTIC, and Fu Cuixiao, Research Fellow at the Industrial Innovation Research Office of our Institute, jointly presented and interpreted the report.　　

　　Currently, five key sci-tech fields—energy, health, information, materials, and manufacturing—have become the main battlegrounds of international sci-tech competition. Focusing on sub-fields such as wind energy, antibody drugs, extended reality (XR), high-performance membrane materials, and advanced sensors, the research adopts methods including literature review, expert interviews, bibliometrics, patentometrics, and knowledge mapping. It conducts an in-depth analysis of development trends in these fields from the perspectives of policy planning, basic research, technological R&D, talent pools, and industrial status.　　

　　Additionally, leveraging the Institute's "Technology Foresight Platform," the study released the "Sci-Tech Star Map 2025." Focusing on cutting-edge directions such as brain-inspired intelligence, perovskite batteries, metamaterials, and AI-assisted healthcare, the report carries out annual dynamic tracking to identify domain hotspots and significant technological progress, providing a reference for decision-making in the innovative development of key sci-tech fields in Shanghai.
