摘要(Abstract)：

针对我国农业水价偏低、调价困难、现有承受能力方法评估不完善等问题，且地方政府调价需系统科学的依据，明确各区域农业水价承受能力底数，研究改进了以往水费支出系数的经验性取值，筛选各区域现状高水费支出系数作为承受能力水费支出系数平均值，结合指数分析法和计量经济学法，综合考虑降水量、单位面积产值等影响因素，构建其与水费支出系数关系模型，最终计算给出分区域分不同作物的农业水价承受能力和调价空间。结果表明：粮食作物水费支出系数在2.620%～12.950%之间，水价承受能力在0.058～0.521元/m~3之间，经济作物水费支出系数在5%左右，水价承受能力在0.178～4.329元/m~3之间。研究表明：东北、西北和华北地区的水费支出系数和农业水价承受能力总体高于西南和华南地区；黄河流域粮食作物和经济作物水价承受能力要高于长江流域，但该流域调价空间较长江流域略低，尤其粮食作物，调价空间有限，各区域经济作物均具有充分的调价空间。

关键词(KeyWords)： 农业水价承受能力;水费支出系数;单位面积产值;降水量;调价空间
