科学与技术结构图谱视角下的国际科技创新中心比较研究OACHSSCD

[Purpose/Significance]International science and technology innovation hubs serve as crucial hubs and nodes within the global innovation network.By comparing the scientific structures,technological structure,and innovation-driven development modes of international science and technology innovation hubs at home and abroad,and integrating the specific context of domestic development,this study identifies future development directions and provides policy recommendations for the practical construction of China's inter-national science and technology innovation hubs.[Method/Process]Using the Essential Science Indicators database and patent families from the U.S.and Europe as data sources,this study applies deep learning models to construct scientific structure mapping and technological architecture maps.Through a comparative analysis of research hotspots and technological specialization patterns across international sci-tech innovation hubs,the study uncovers China's competitive advantages and developmental weaknesses.[Result/Conclusion]The study reveals three key findings:① From the perspective of scientific research,foreign sci-tech innovation hubs prioritize artificial intelligence,physics,biomedicine,and earth sciences,whereas Chinese hubs empha-size artificial intelligence,physics,chemistry,materials science,environmental and energy sciences;② From the perspective of technological innovation,Tokyo manifests comprehensive coverage across all technological domains,while California,Beijing,and Shenzhen demonstrate strategic concentration in digital communication and artificial intelligence technologies.Comparatively,New York,London,Paris,and Shanghai exhibit diversi-fied technological portfolios characterized by interdisciplinary integration and multi-sectoral synergy;③ From the perspective of innovation models,California and Paris are synergistic development-oriented science and technology innovation hubs.New York,London,Beijing,and Shanghai are knowledge-driven science and tech-nology innovation hubs.Tokyo and Shenzhen are technology-driven science and technology innovation hubs.This study proposes that China can build an international science and technology innovation hub by strengthen-ing fundamental research capabilities,fostering globally competitive leading science and technology enterpris-es,and technology innovation enterprises,and promoting collaborative innovation among multiple entities.
