Abstract: By analyzing the connotation of technological power and establishing an analytical framework for technological leadership, this paper explores the competitive situation of the United States in Artificial Intelligence(AI) leadership from three dimensions: innovation capability, industrial capability, and innovation ecological competitiveness, and provides targeted suggestions for China. Adopting processtracking research to analyze AI competition of the United States, and using the data of AI research and industry from European and American universities and think tanks to support relevant competitiveness comparison and analysis. The paper considers that ,the AI strategy of the United States presents practicality ,efficiency and competition oriented. With the upgrading of competition in AI technological leadership, the United States recognized that a single export control on AI chips was ineffective. It began to shift its focus to innovative research, industrial development, and ecological construction as a whole. Through a series of measures such as R&D decoupling, security verification, chip deterrence, supply dismantling, standard dominance, and narrative confrontation, the United States aimed to gain technological leadership by competition. China can actively respond by jointly building highlevel domestic innovation system, AI+independent industry system and global AI governance system.
