Abstract

The digital economy (DE) and real economy (RE) are dual pillars of the modern economic system. The deep integration of the digital economy and real economy (IDR) has emerged as a pivotal strategic trend. IDR not only can enhance international competitiveness but also contributes to sustainable development goals. This work collects DE and RE data from 30 provinces in China between 2012 and 2022. The entropy weight method and the coupling coordination degree (CCD) model are employed to measure the level of IDR. Furthermore, the Dagum Gini coefficient, Kernel density estimation, the spatial autocorrelation model, and the geographically and temporally weighted regression (GTWR) model are utilized to analyze the spatial–temporal evolution and influencing factors of CCD. The following conclusions are drawn: (1) During the study period, CCD shows an upward trend, but the value is relatively low. (2) There are significant spatial differences in CCD, and the inter-regional difference is the primary cause. (3) The regional differences in CCD are continuously widening. (4) CCD shows an obvious global spatial agglomeration feature, and the spatial agglomeration degree of CCD has been enhanced from 2012 to 2022. (5) The policy intensity, digital infrastructure, industrial structure, human capital, technological innovation, and market environment have significant impacts on CCD. The obtained findings provide important theoretical support for the coordinated development of DE and RE.
