Abstract:At present, digital currency has increasingly become an important item in global financial competition. In the field of non-statutory digital currency, the issuance and transaction policies of the United States are relatively open; in the field of legal digital currency, China has made rapid progress in research and development, patent declaration, and currency trials. Deriving from the four scenarios of Sino-US digital currency competition, the confrontation between China and the United States in the field of digital currency has become a high probability event. China should adhere to an open and cooperative attitude in the international competition of digital currencies, while also deploying strategies to deal with extreme situations in advance. China should take the lead in issuing central bank digital currency and form a "Chinese sample" based on the advantages of complete infrastructure and rich application scenarios; it should improve the technical level of digital currency and strengthen the research and development of underlying algorithms and key technologies; it is recommended that China and the Belt and Road countries Share experience in this field, accelerate the construction of RMB cross-border payment system, and build a good cross-border payment ecology.
