摘要
文章采用数据包络分析方法,对朝阳市农业干旱用水效率进行测算。测算结果表明:当朝市农业产出和投入指标分别为0.45和0.56时,农业干旱用水效率一般<50%,应加强农业产出和投入指标的优化,从而提高农业干旱用水效率。
The data envelopment analysis method is used to calculate the water efficiency of agricultural drought in Chaoyang City.The calculation results show that when the agricultural output and input indicators of the Korean market are 0.45 and 0.56 respectively,the water efficiency of agricultural drought is generally lower than 50%.The optimization of agricultural output and input indicators should be strengthened to improve the water efficiency of agricultural drought.
