[Objective] The coupled and coordination relationship between the ecological efficiency of cultivated land use and the urbanization process in Shaanxi Province was explored in order to provide a theoretical basis for the formulation of policies related to urbanization development and cultivated land protection in Shaanxi Province. [Methods] Based on the panel data of each county in Shaanxi Province from 2005 to 2019, we established system of ecological efficiency of cultivated land use and the evaluation index system of urbanization process, the ecological efficiency and urbanization level of county-level unit farmland use were measured, the coupling coordination degree model was used to explore the coupling coordination relationship between the two, and the spatial autocorrelation method was used to analyze the spatial pattern evolution characteristics of each county-level unit farmland use ecological efficiency and urbanization development. [Results] The level of ecological efficiency of cultivated land use in Shaanxi Province decreased from 0.765 in 2005 to 0.684 in 2019, but the overall ecological efficiency value of cultivated land use was relatively high and there was spatial variability among counties. The ecological efficiency of cultivated land use in each district and county clustered in clusters, and the differences between northern Shaanxi, central Shaanxi and southern Shaanxi gradually decreased over time. The overall urbanization level in Shaanxi Province had increased by 198.24% from 2005 to 2019, with an overall distribution trend of ‘high in the central part and low in the north and south', with the central Shaanxi being the core area for population urbanization, economic urbanization and land urbanization, and the overall rate of change followed the order: economic urbanization>population urbanization>land urbanization. The level of coupling between the ecological efficiency of cultivated land use and urbanization in county units in Shaanxi Province was mainly in the transition stage from low-level coupling to antagonistic coupling from 2005 to 2019, with 25% of districts and counties increasing their coupling. The type of coupled coordination between urbanization and ecological efficiency of cultivated land use in Shaanxi Province from 2005 to 2019 was dominated by three grades: mildly dysfunctional, on the verge of dysfunctional and barely coordinated. The number of districts and counties with primary coordination and barely coordinated had been increasing during the study period, and the overall development trend had been improving. The degree of coupled coordination showed a strong positive correlation in space, but there were obvious internal differences in local spatial aggregation. [Conclusion] The coupled and coordinated relationship between urbanization and ecological efficiency of cultivated land use in Shaanxi Province from 2005 to 2019 showed an overall trend of becoming better. In the future, Shaanxi Province should formulate differentiated economic development policies to promote urbanization in an orderly manner, while optimising the spatial layout of regional development and accelerating the formation of a positive regional interaction pattern.
