The construction of China's digital healthcare system faces multiple challenges, such as the interest coordination dilemma within the "tripartite synergy of doctors" mechanism, uneven resource allocation, and incomplete policies and regulations. Based on the perspectives of organizational optimization and economic resource allocation, and combined with digital transformation scenarios, this paper proposes reconstructing the synergy mechanism among government, industry, academia, research, and medical institutions. It also suggests optimizing health insurance payment and data sharing models, and strengthening the integration of information technology into primary healthcare, among other pathways, to enhance the system's effectiveness. The study emphasizes that innovating the digital governance structure should be the core focus, promoting synergy between technology and institutional systems to achieve efficient allocation and equitable distribution of medical resources, thereby providing theoretical support for the Healthy China strategy.
