Abstract: With global population growth and economic development, the sustainable utilization of arable land resources has become the key to guaranteeing food security and ecological balance. Eco-efficiency in cultivated land use (ECLU)has been increasingly emphasized as an important indicator of the coordinated development of agricultural production and the ecological environment. Studying ECLU in main grain-producing areas (MGPAs) is of great significance for realizing China’s food security guarantee, formulating and implementing scientific land use policies and measures, and safeguarding the long-term healthy development of agriculture. Based on provincial panel data of MGPA from 2008–2021, ECLU is calculated by the super-efficiency slacks-based measure model based on non-desired outputs (SSBM) and non-parametric kernel density estimation. The Dagum Gini coefficient decomposition model was used to explore the spatial non-equilibrium characteristics of ECLU in China, and the geographical and temporal weighted regression (GTWR) model was used to analyze the influencing factors of ECLU. The results showed the following: (1) ECLU in the MGPA showed a fluctuating upward trend, but the overall level was low. (2) In terms of regional disparity, the absolute difference in the development of ECLU among provinces showed a trend of “small-scale expansion followed by reduction”. (3) ECLU showed significant spatial imbalances, with notable internal disparities within the three basins. (4) The effects of economic development level and agricultural irrigation index on ECLU in the MGPA were positively correlated. Based on these findings, this paper suggests implementing region-specific and phased policies tailored to the natural resources and socio-economic conditions of different areas. The aim is to enhance the ecological environment, promote coordinated agricultural development, optimize regional growth, reduce agricultural disparities, and achieve sustainable development for both people and arable land.
