摘　　要：基于海南省18个市(县)2012—2022年县域行政单元农业面板数据,运用非期望产出超效率SBM模型,结合空间相关性分析方法,分析海南省农业生态效率时空演变特征,并利用Tobit回归模型探究其影响因素。结果表明:(1)2012—2022年,海南省农业生态效率均值呈现中部地区>西部地区>东部地区的明显分级特征;海南省市(县)域尺度农业生态效率逐年明显改善,农业生态效率均值为0.541,达到均值以上的市(县)数为7个。(2)空间变化上,总体呈现中部向东西部扩散的空间分布特征,同时完全有效和效率较高呈现块状和链条式分布特征,效率中等类型市(县)围绕着完全有效和效率较高市(县)分布;南北方向和东西方向的投影趋势线均呈现倒“U”型特征。(3)在省域尺度下,农民收入水平、农业机械化强度、农业化学投入品使用强度和城镇化率是对海南省农业生态效率时空演变产生影响的主要因素;在不同区域尺度下,农民收入水平是对东部地区农业生态效率产生影响的主要因素,城镇化率、农业化学投入品使用强度和农田灌溉率是对中部地区农业生态效率产生影响的主要因素,城镇化率、农民收入水平、农业产业结构、农业化学投入品使用强度和农田灌溉率是对西部地区农业生态效率产生影响的主要因素。总体而言,海南省各市(县)农业生态效率整体呈上升趋势,各区域农业生态效率存在一定差异。未来应因地制宜探索不同地区农业发展重点,切实提升农业生态效率。Based on the panel data of 18 cities(counties)in Hainan,China from 2012 to 2022,combining the non-expected output super efficiency SBM model and Tobit regression mode,this paper analyzed the spatial and tem-poral evolution characteristics of agricultural eco-efficiency and influencing factors of agricultural ecological efficiency in cities(counties)of Hainan.From 2012 to 2022,the average agricultural eco-efficiency in Hainan showed obvious grading characteristics of central region>western region>eastern region.The agricultural eco-efficiency at the county scale of Hainan improved significantly year by year.The average agricultural eco-efficiency was 0.541,and the number of cities(counties)above the average value was 7.In terms of spatial change,the overall distribution characteristics of agricultural eco-efficiency were“spreading from the middle to the east and west”,and the distribution characteristics of full efficiency and high efficiency were block and chain.The cities(counties)with medium efficiency were distributed around the cities and counties with full efficiency and high efficiency.The trend lines in the north-south direction and the east-west direction showed the characteristics of inverted U-shape.The temporal and spatial evolution of agricultural eco-efficiency in Hainan at the provincial scale was influenced by several key factors,including the level of farmers’income,intensity of agricultural mechanization,use of agricultural chemicals,and urbanization rate.At different re-gional scales,farmers’income level was the main factor affecting agricultural eco-efficiency in the eastern region,while urbanization rate,intensity of agricultural chemical input use and farmland irrigation rate were the main factors affecting agricultural eco-efficiency in the central region.Urbanization rate,farmers’income level,agricultural industrial structure,intensity of use of agricultural chemical inputs and farmland irrigation rate were the main factors affecting agricultural eco-efficiency in the western regi
