The digital economy era has promoted the in-depth development of RMB digitization, changed the traditional financial service model, and had a significant impact on the competitiveness of private enterprises. Since 2014, the People's Bank of China(PBOC)has continued to promote the research and piloting of digital RMB, and by the end of 2022 its circulating stock had reached 13.61 billion yuan. The promotion of digital RMB improves payment efficiency, reduces the cost of traditional cash transactions, and provides private enterprises with convenient access to financing. In the new digital context, the application of fintech has improved innovation, financing efficiency and risk control, especially the implementation of cloud computing and blockchain technology, which significantly reduces operating costs and promotes competitiveness. Despite the opportunities brought by digital transformation, private enterprises still face multiple challenges such as technology integration, capital investment and risk management. This study aims to analyze the impact mechanism of RMB digitization on private enterprises in the field of fintech and to propose coping strategies to help private enterprises participate more effectively in the development of the digital economy.
