摘　　要：研究目的:揭示区域耕地利用效率的空间非均衡性及其影响因素,为区域耕地资源的优化配置及高效利用,推进农业高质量发展提供科学依据。研究方法:Super-SBM模型、Dagum基尼系数和地理探测器。研究结果:(1)从时间序列看,2009—2019年广东省耕地利用效率总体呈现微弱下降趋势,研究期内均值为0.783;区域上,珠三角地区耕地利用效率持续提升,西翼、东翼和山区则呈不同幅度降低趋势。(2)从空间维度看,广东省耕地利用效率具有显著的空间特征,呈高—低效率区多核心成片集中分布格局。(3)广东省耕地利用效率存在明显空间非均衡性,整体呈现波动上升态势,且区域间差距为空间非均衡性的主要来源,其次是超变密度,区域内差距的贡献率最小。(4)整体而言,自然禀赋、社会经济和农业生产技术影响广东省耕地利用效率空间格局分异,其中水田面积占比、农村居民人均可支配收入和人均耕地面积为主导影响因子,但四大区域主导影响因子及其作用力存在显著差异。研究结论:不同区域应因地制宜、因城施策,科学配置资源以推进耕地利用效率的区域协调发展,同时注重耕地利用的非期望产出效应,优化农业生产结构,促进耕地利用效率的提升。The purposes of this paper are to reveal the spatial imbalance of regional cultivated land utilization efficiency and its influencing factors,and to provide a scientific basis for the optimal allocation and efficient use of regional cultivated land resources,and to promote the high-quality development of agriculture.The research methods are Super-SBM model,Dagum Gini coefficient and geodetector.The results show that:1)in terms of time series,the overall cultivated land use efficiency of Guangdong Province showed a slight downward trend from 2009 to 2019,with an average value of 0.783 during the study period.Regionally,the utilization efficiency of cultivated land in the Pearl River Delta region has continued to increase,while the west wing,east wing and mountainous areas have shown varying degrees of decline.2)In terms of spatial dimensions,the utilization efficiency of cultivated land in Guangdong Province has significant spatial characteristics,showing a concentrated distribution pattern of multiple cores in high-low efficiency areas.3)There is obvious spatial imbalance in the utilization efficiency of cultivated land in Guangdong Province,and the overall volatility is increasing.The regional gap is the main source of spatial imbalance,followed by the hypervariable density,and the contribution rate of the regional gap is the smallest.4)Generally,natural endowment,social economy and agricultural production technology affect the spatial pattern of cultivated land use efficiency in Guangdong Province.The proportion of paddy field area,the per capita disposable income of rural residents and the per capita cultivated land area are the dominant factors.However,there are significant differences in dominant factors of the four major regions and their forces.In conclusion,different regions should adopt the context-specific measures and policies,and scientifically allocate resources to promote the coordinated development of cultivated land use efficiency.At the same time,the undesired output effects of cultivated land us
