The deep integration of the digital economy and the real economy serves as a new driving force for achieving new-type urbanization and rural modernization in China and constitutes a critical impetus for urban-rural integrated development.Based on panel data covering 280 prefecture-level cities from 2011 to 2022，this study empirically examines the impact of digital-real integration on urban-rural integrated development.The research findings reveal that digital-real integration significantly promotes urban-rural integration.Mechanism analysis indicates that this effect operates through economic agglomeration，employment expansion，infrastructure improvement，and ecological pressure alleviation.Heterogeneity analysis shows that the promoting effect of digital-real integration on urban-rural integrated development is more pronounced in eastern and southern regions，large/medium-sized cities and cities with higher economic scale，national e-commerce demonstration cities，smart cities，and non-primary grain-producing areas.Further analysis demonstrates that the promoting effect of digital–real integration on urban–rural integrated development is nonlinear，exhibiting a single-threshold effect，and that urban-rural integrated development further enhances urban resilience.
