摘　　要：采用全局超效率SBM模型测算2001—2015年中国30个省市自治区的农业生态效率,并考察了中国农业生态效率的空间分异与提升潜力。研究发现:中国的农业生态效率普遍偏低,但整体呈持续上升趋势;各地区的农业生态效率呈"东西高、中部低"的空间格局和"高高集聚、低低集聚"的分布形态;三大地区分层方式对于农业生态效率空间分异的解释程度不足30%,要素效率等级分层方式对于空间分异的解释程度超过了60%;过多的农机动力、播种面积投入以及过量的农业碳排放是农业生态低效率的重要原因。因此,可以通过避免农机动力浪费、推进土地轮作休耕、加强农业碳排放管控等方式,协同提升区域农业生态效率。The global super-efficient SBM model was used to measure the agricultural ecological efficiency of 30 provinces in China from 2001 to 2015,and to examine the spatial differentiation and potential for improvement of agricultural ecological efficiency in China. The results show that the agricultural eco-efficiency in China is generally low,but it is on the rise on the whole;the agricultural eco-efficiency of the eastern and western regions is higher than that of the central region,and the polarization characteristics become more obvious;the degree of the stratification of the three regions for the spatial differentiation of agricultural eco-efficiency is less than 30%,and the degree of the stratification of factor efficiency hierarchy for the spatial differentiation is more than 60%;excessive input of agricultural machinery power and planting area,and excessive agricultural carbon emissions are the important causes for agricultural ecological inefficiency. Therefore,regional agricultural eco-efficiency can be synergically enhanced by avoiding waste of agricultural machinery power,promoting land rotation and fallowing,and strengthening the control of agricultural carbon emission.
