In order to explore the impact of the urbanization process on the efficiency of cultivated land, this study focuses on the analyses of the spatiotemporal pattern, spatial autocorrelations and impact mechanism of the development of urbanization on the cultivated land use efficiency of 108 counties by using the method of Entropy Method, Comprehensive Score Method, Coefficient of Variation Method, Super-efficiency DEA Model, Exploratory Spatial Data Analysis (ESDA) and Geographically Weighted Regression (GWR) in He’nan Province from 2000 to 2014 based on the index system for coordinated development of urbanization and the cultivated land use efficiency index from the input-output angle. Results indicate that:the total number of counties with effective land use efficiency in the frontier of production decreases, the DEA efficiency value is always valid in 10 counties and 51.85% of the counties with decreasing land use efficiency during the study period; the urbanization coordination degree and land urbanization shows a certain spatial negative correlation with cultivated land use efficiency, while the spatial correlation of economic urbanization, population urbanization and social urbanization with cultivated land use efficiency is not obvious; The explanatory variables of the subsystems of urbanization have different results for the estimation of the parameters of each county level unit in He’nan Province, and positive and negative regression results both exist, which demonstrates significant spatial differences, economic urbanization exhibits a significant positive spatial correlation.
