The digital economy is the economic foundation for humanity to move from industrial civilization to digital civilization. Especially due to its basic attributes of “linking” and “sharing”, the digital economy can provide strong impetus for accelerating the formation of new productive forces and leading the high-quality development of the Chinese economy through extensive empowerment. At present, the digital economy has become the main field of global technological competition and industrial competition. Enhancing the international competitiveness of the digital economy is an inevitable choice and path to accelerate the construction of a new development pattern and move towards “digital China”.　Based on the research of enhancing the competitiveness of digital economy countries, the first route focuses on the empirical research on digital technology, data elements, and the consequences of the digital economy; the second route focuses on measuring the scale and competitiveness of the digital economy, as well as country analysis, believing that the scale and international competitiveness of China’s digital economy have improved to varying degrees; the third route focuses on the promotion path and development idea of the digital economy, believing that the digital economy will not only present a new development path and mode, but also inevitably need to be coordinated with important national strategies. This paper is based on the perspective of a promising government from an international view, systematically studies the government’s functional positioning and main policy deployments in enhancing the international competitiveness of the digital economy, and diagnoses the core barriers and breakthrough paths for China’s digital economy to enhance its international competitiveness.　The results indicate that there is common experience between the US and the EU in enhancing the international competitiveness of the digital economy. At the level of strategic deployment, it is reflected in focusing on technological competition and digital ecosystem construction to carry out strategic deployment; at the level of talent element, it is focused on the cultivation and introduction of digital talents to carry out multi-level digital-talent policy deployment; at the level of subject selection, large digital enterprises have become key innovative entities for enhancing the competitiveness of the digital economy; at the level of institutional support, tax system reform should be carried out based on our own digital economy endowment and development demands. At present, China’s digital economy is developing rapidly in the process of industrial digitization, digital technology innovation, and digital trade. In the future, it is urgent to build a policy system for open digital economy development strategy deployment and key digital technology tackling, a policy system for multi-level digital talents, and a digital tax system suitable for the development of the digital economy.
