Based on the construction of a theoretical framework for the impact of digital village construction on county-level in-situ urbanization，this study matches county-level digital rural indices with county panel data to examine the impact of digital rural construction on county-level in-situ urbanization and its mechanisms.The findings indicate that the implementation of digital villages construction can effectively facilitate in-situ urbanization in counties，with digital infrastructure，economic digitization，governance digitization，and daily-life digitization all demonstrating positive effects，though governance digitization exhibits relatively weaker influence.Furthermore，the digital rural construction generates a positive spatial spillover effect on in-situ urbanization in counties.The equalization of public services and the upgrading of the industrial structure are identified as dual transmission pathways through which digital rural construction drives county-level in-situ urbanization，though their spatial spillovers currently show contrasting directions （positive vs. negative， respectively）.Direct effects are observed for all control variables except human capital，with foreign capital utilization and transportation accessibility exhibiting positive and negative spatial spillovers correspondingly.Therefore，to advance high-quality in-situ urbanization，we propose integrated strategies：promoting digital rural construction combined with public service equalization，coupling agricultural production services with industrial development and enhancing cross-county multi-tier collaboration and human capital investment.
