  The rapid development of the digital economy has had a profound impact on the
implementation of the rural revitalization strategy. Based on this, this study
takes Hainan Province as the research object to deeply explore the impact of
digital economic development on rural revitalization. The study collected panel
data from 2003 to 2022 to construct an evaluation index system for the digital
economy and rural revitalization and used panel regression analysis and other
methods to explore the promotion effect of the digital economy on rural
revitalization. Research results show that the digital economy has a
significant positive impact on rural revitalization, and this impact increases
as the level of fiscal expenditure increases. The issuance of digital RMB has
further exerted a regulatory effect and promoted the development of the digital
economy and the process of rural revitalization. At the same time, the
establishment of the Hainan Free Trade Port has also played a positive role in
promoting the development of the digital economy and rural revitalization. In
the prediction of the optimal strategy for rural revitalization based on the
development levels of the primary, secondary, and tertiary industries (Rate1,
Rate2, and Rate3), it was found that rate1 can encourage Hainan Province to
implement digital economic innovation, encourage rate3 to implement promotion
behaviors, and increase rate2 can At the level of sustainable development when
rate3 promotes rate2's digital economic innovation behavior, it can standardize
rate2's production behavior to the greatest extent, accelerate the faster
application of the digital economy to the rural revitalization industry, and
promote the technological advancement of enterprises.
