The vigorous development of the digital economy provides a new research perspective for alleviating local financial pressure. Based on the provincial panel data from 2013 to 2020, the mediating effect model and threshold regression model were used to explore the effect and mechanism of the digital economy on local fiscal pressure. The research shows that the digital economy has a significant alleviating effect on local financial pressure by increasing fiscal revenue, and this alleviating effect has a threshold effect on entrepreneurial activity. From the perspective of dimension, the alleviating effect of the digital economy development environment on local financial pressure is better than that of digital industrialization and industrial digitization. From a regional perspective, the digital economy has the most apparent impact on the western region. In addition, the quantile regression results show that with the increase in financial pressure, the easing effect of the digital economy shows an inverted U-shaped change. Therefore, in order to effectively alleviate the financial pressure on local governments, China should continue to promote the development of the digital economy, take multiple measures to increase entrepreneurial activity, and encourage various regions to implement differentiated digital economy development strategies according to local conditions.
