Abstract:      The rapid development and application of digital technology is weakening the traditional national advantage and reconstructing the world′s competition landscape, which urges countries to develop digital development strategies to seize the high ground of digital technological innovation and form the digital competitive advantage. By sorting out and summarizing the digital development strategic path models of major developed countries, and exploring the internal relationship mechanism and theoretical framework of digital economy, digital government and digital social development, it will provide theoretical support and model mirror for China′s current digital development. However, the existing literature on digital development mostly discusses its development path and construction logic from of digital government, digital economy, and digital society respectively, few literatures analyze the development logic and theoretical framework from an overall perspective. Based on the analysis of the evolution law and practical experience in digital development strategies of major developed countries such as the United States, the United Kingdom, Germany and Japan, this paper constructs a theoretical framework of national digital development based on digital economy, digital government and digital society. 
     The results found that: (1) The origin of digital development in various countries is different, but its content focuses on three aspects: digital economy, government and social development; (2) The digital development strategy evolution of the four countries, the United States, the United Kingdom, Germany and Japan, has formed different digital economy development modes, such as "technology-system" double-wheel driving, "government-policy" pulling, industrial upgrading promoting, social demand pulling, but all development focus of the evolution process has turned to the digital economy as the center of gravity; (3) The digital development strategy should take the digital economy as the main body, the digital government and the digital society as the two wings. The three aspects support each other, penetrate and blend with each other, and advance together. 
     Based on this, the study puts forward the logic and countermeasures of digital development in the Chinese context. The development logic is the development of the digital economy continues to provide technical and service support for the constructions of digital government and digital society, the digital government empowers the digital economy and digital society to deepen development through top-level design and system reshaping; and the digital society provides long-term growth momentum for the digital economy and help the overall improvement of the effect of digital government governance. 
    The policy implications include: reconstructing the top-level design of the digital background, giving full play to the leading role of the government, guiding the participation of multiple parties, cultivating the digital literacy of the whole society, building a digital ecology, and activating data productivity. In addition, it puts forward the prospect of the future path of China further digital development in the three aspects of digital economy, digital government and digital society.
