Based on the data of 30 provinces in China from 2010 to 2020,this paper uses entropy weight method to statisti-cally measure the development level of digital economy in each province,and constructs panel fixed effect model,intermediary ef-fect model and threshold regression model to test the influence effect,transmission mechanism and nonlinear characteristics of digital economy on regional innovation and entrepreneurship.The results are shown as follows:(1)Digital economy has a signifi-cant boosting effect on regional innovation and entrepreneurship,and this effect is more obvious in the western and northern re-gions.(2)Innovation resource allocation and transaction costs play a positive mediating effect in the process of digital economy driving regional innovation and entrepreneurship.(3)The impact of digital economy on regional innovation and entrepreneurship is characterized by marginal decline under the role of green innovation and marginal increase under the role of business environ-ment and human capital investment.
