Abstract: Public services play an important role in the development of digital economy.Digital transformation is not only the need of the times for the high-quality development of public services,but also a key measure to promote the high-quality development of public services.By constructing the evaluation index system for the digital economy and high-quality development of public services,using the provincial panel data from 2011 to 2023,this paper uses entropy method,coupling coordination model,spatial autocorrelation model and spatial Dubin model to explore the spatiotemporal pattern and influencing factors of the coupling coordinated development of the two.The results show that:In the time dimension,the coupling coordination degree of digital economy and high-quality development of public services is generally on the rise.In the spatial dimension,the coupling coordination degree of the two shows the decreasing laws of the eastern-central-western ladder.From the perspective of the type of coupling coordinated development,“mild imbalance-digital economy lag type” accounts for the highest proportion,“moderate imbalance-digital economy lag type” takes the second place,and “mild coordination-digital economy lag type” ranks third.From the perspective of spatial correlation of coupling coordination degree,there are significant positive spatial autocorrelation characteristics in the whole region,and the local spatial autocorrelation is dominated by “high-high” and “low-low” agglomeration.From the perspective of the influencing factors of coupling coordination degree,technological innovation,economic development,industrial structure,fiscal expenditure,urbanization and infrastructure all play a positive role in promoting the coupling coordinated development of the two systems.Therefore,it is necessary to strengthen the innovation-driven engine,innovate the integrated development paradigm,build a cross-regional coordinated development mechanism,improve the institutional guarantee system,and promote the mutual development of digital economy and public services.

Key words: digital economy, public services, coupling coordination, spatiotemporal evolution
