| 中文摘要: |
| 为研究我国2010—2017年农业资源投入产出效率及时序演化特征，采用数据包络分析（DEA）方法，以中国内地31个省份为研究对象，基于农业生产中的水-能源-粮食纽带关系，构建了以农业用水量、能源产品使用量、排灌耗能量、能源产品生产用水量作为输入变量，以主要农产品生产总量、第一产业国内生产总值（第一产业GDP）为输出变量的评价指标体系。结果表明，我国有19个省份尚未达到DEA有效状态，大部分省份的农业资源投入产出效率有较大上升空间。研究表明，我国大部分省份（20个）的综合效率主要受纯技术效率的影响，其中最典型的宁夏、甘肃、新疆三个西北省份的纯技术效率明显落后，资源利用效率和管理水平有待提高。 |

| Taking 31 provinces of China as the research target, an evaluation index system with agricultural water consumption, agricultural energy consumption, energy consumption of irrigation and drainage, and water consumption of energy production as the input variables and total production of the main agricultural products and gross domestic product of the first industry as the output variables was established based on the water-energy-food nexus in agricultural production. Data envelopment analysis(DEA)was used to calculate the input-output efficiency of agricultural resources in China from 2010 to 2017, and its temporal evolution characteristics were analyzed. The results showed that 19 provinces in China had not yet reached the DEA effective state, and the input-output efficiency of agricultural resources in most regions had large room for growth. The comprehensive efficiency of 20 regions was mainly affected by the pure technical efficiency, while the pure technical efficiency of Ningxia, Gansu, and Xinjiang was clearly backward and the resource utilization efficiency and management level need to be improved. |
