Abstract: At the convergence of a new wave of technological and industrial transformation with unprecedented global changes, technology security has emerged as a central concern for major economies in global technology competition. This study examines global technology development and competitive dynamics through three dimensions: global technology development trends, global technology security landscape, and technology strategies of major powers. The global technology architecture is transitioning from a unipolar-multipolar structure to a “2+N” configuration, characterized by active interdisciplinary innovation and large-scale centralized innovation, alongside a restructuring of the global technology division of labor. Leading nations have positioned technology security as a core national interest, marking a new era in geopolitical contests among major economies over technology security. China should adopt a strategic framework emphasizing global landscape changing, internal capacity building, and measured countermeasures, developing high-quality policy systems across institutional design, management frameworks, and international cooperation to stimulate technological vitality and address technological challenges.
