Abstract:In the new era of digital economy, digital currency is an inevitable trend in the development of human currency, and the digitization of RMB is an inevitable trend in the development of my country's currency system. The digital development of the RMB will definitely have a certain impact on the RMB exchange rate. By establishing the Markov regional system transfer model of the three-region system, this paper uses the exchange rate data of RMB to USD from June 25, 2019 to April 30, 2021, and takes May 29, 2020 as the node of RMB digitization. An empirical analysis of the regional transfer characteristics of the exchange rate in the two periods before and after is conducted to analyze the impact of the development of the digital renminbi on the renminbi exchange rate. The results show that the digital development of the RMB does have an impact on the RMB exchange rate, and the Markov regional system transfer model has undergone a state transfer after the RMB digitization, which further verifies the effectiveness of the regional system transfer model for analyzing long-term series data, which makes up for it. Limitations of Simple Time Series Models.
