Abstract
In this study, super efficiency SBM-DEA model was used to estimate the total water use efficiency of agricultural factors in the Beijing-Tianjin-Hebei region from 2000 to 2013, and on this basis, panel Tobit model was used to test the influence of natural conditions, water conservancy facilities, agricultural production conditions and social and economic conditions on the total water use efficiency of agricultural factors. The results show that although the overall water use efficiency of agriculture in Beijing-Tianjin-Hebei region is higher than the national level, there is still room for improvement. In the future, it should strengthen the protection and cooperation of agricultural water resources and water-saving technologies in the three regions. shared; The ratio of groundwater to water supply structure and the price index of agricultural production materials have a significant positive impact on the water efficiency of all-factory agriculture in Beijing-Tianjin-Hebei. The reservoir capacity, animal husbandry and fishery account for the proportion of total value of agricultural output the per capita cultivated land area, and the per capita net income of rural households. The quality of rural labor has a significant negative impact on the water efficiency of all-factory agriculture in Beijing, Tianjin and Hebei.
