Abstract:A detailed analysis of the United States' development trajectory and effective strategies in the field of artificial intelligence (AI) provides significant guidance for China in constructing its AI ecosystem. This study adopts a methodology combining policy interpretation and case analysis across three dimensions: institutional setup, policy formulation and practical implementation, to comprehensively examine how the U.S. federal government plans and facilitates AI development. The U.S. federal government agencies involved in AI are categorized into three levels: decision-making, promotion and execution. The decision-making level includes the President’s Council of Advisors on Science and Technology, the Office of Science and Technology Policy, and the National Science and Technology Council. These agencies play crucial roles in proposing policy recommendations, determining policy directions and formulating relevant plans within the U.S. AI strategic framework. The promotion level mainly consists of entities like the National Science Foundation and various federal departments such as the Department of Energy, the Department of Commerce and the Department of Defense, which are responsible for implementing the decisions, initiating numerous projects to advance AI. The execution layer primarily involves U.S. national laboratories, top university labs and leading technology companies. Moreover, the U.S. continuously updates its National AI R&D Strategic Plan and implements initiatives such as the “AI Bridges” program to promote practical applications of AI.Considering the specific situation of AI development in China, the paper suggests strategies to accelerate China’s progress in AI and secure a technological innovation advantage. These include establishing specialized AI institutions, creating AI research centers and building a comprehensive and diversified AI talent development system.
