Based on the theoretical analysis of digital economy unblocking the domestic circulation,and by using the panel data of 30 provinces in China from 2012 to 2020,this paper adopts the entropy weight method to measure the development level of the digital economy in each province,and empirically test the mechanism,heterogeneity characteristics and spatial spillover ef-fects of the digital economy unblocking the domestic circulation,as well as the threshold effect of digital inclusive finance.The re-sults show that digital economy has a significant impact on the construction of the domestic circulation,this conclusion remaining valid after a series of robustness and endogenous tests.Heterogeneity analysis shows that the impact of digital economy on the do-mestic circulation is stronger in southern regions and at low levels of digital inclusive finance.The mechanism analysis results show that digital economy can unblock the domestic circulation through the real economy development and regional innovation.In addition,the spatial econometric analysis results show that digital economy can not only unblock the domestic circulation in the re-gion,but also facilitate the domestic circulation in neighboring regions.
