Why Does the U.S. Dominate the Digital Economy? A Strategic Analysis Based on the Policy–Coordination–Talent Framework and the Policy Implications for China

The digital economy is a key area for nurturing new productivity and a strategic high ground for innovative development and international competitiveness. This paper innovatively constructs the PCT (Policy–Coordination–Talent) analysis framework to systematically analyze the U.S. digital economy development model from three core dimensions: policy guidance, coordination mechanisms, and talent strategy. Through empirical analysis, the research develops three matrices: a leading policy intensity strategy matrix, a coordination mechanism intensity strategy matrix, and a digital talent cultivation strategy matrix. The findings reveal that the U.S. government has formed a resilient digital economy development paradigm through forward-looking policy guidance, precise coordination mechanisms, and systematic talent strategies. The theoretical contributions include developing a multi-dimensional PCT framework for understanding digital economy development models and constructing three strategy matrices based on real data. The research provides theoretical insights and policy implications for China to improve its digital economy governance system and promote high-quality development.
