Agriculture Irrigation Efficiency Comparative Analysis under the Background of Drought ——the evidence from Hebei, Henan, Liaoning provinces
Abstract: In this paper, based on the technical efficiency perspective, the DEA method is used to study the irrigation efficiency of irrigated water under the background of drought, and the irrigation efficiency of Hebei, Henan and Liaoning provinces is compared and analyzed. The paper gets the following three conclusions: 1. All three provinces have a lot of room for improvement on the agricultural irrigation water efficiency. The irrigation efficiency under the variable scale hypothesis is generally higher than the efficiency value under the constraint of unchanged scale. Irrigation efficiency is better when the scale of agricultural management can be free to adjust. 2. When three provinces suffered from the drought in 2014, the irrigation efficiency of Henan Province was the least while the available water resources were also the least. The input of water resources to agricultural production was distorted and the market value could not be effectively reflected. 3. The minimum value of irrigation efficiency of farmers in three provinces all are zero. Farmers have irrigation inputs but no output, so inpidual irrigation investment may not be sufficient to cope with the drought, government investment is need for them. Finally, the paper makes some suggestions on the government and farmers for their irrigation water-saving behaviors.
