Abstract:
Objective/Meaning The rebound effect of agricultural water use was introduced to quantify the rating of various regions in Xinjiang, and the influence of agricultural technological progress on the total amount of agricultural water use and water-saving effect in Xinjiang was studied, so as to provide the basis for improving the water saving of agricultural technology in Xinjiang.
Methods/Procedures Based on the panel data of various prefectures in Xinjiang from 2005 to 2020, the DEA model was used to measure the rate of agricultural technological progress in Xinjiang. Through the rebound effect of agricultural water use with the rate of agricultural technological progress, combined with the actual situation, the relationship among the agricultural water-saving technological progress, the rebound effect of agricultural water use and the total amount of agricultural water use was explored.
Results/Conclusions The results showed that: (1) The rate of agricultural technological progress in Xinjiang and its various prefectures was positive and the mean value was greater than 0.9. (2) The mean value of the rebound effect of water use in Xinjiang was 0.96. The agricultural water-saving technology increased the utilization efficiency of water resources and reduced the total amount of agricultural water use, but the effect was not obvious. (3) The rebound effect of agricultural water use was different in different states and there were different degrees of rebound effect of agricultural water use, among which the rebound effect in southern Xinjiang was the most average and the total rebound was the lowest. The distribution of rebound effect in northern Xinjiang was discrete and there was a phenomenon of “tempering”, while the rebound effect in eastern Xinjiang was relatively average. (4) The progress in agricultural technology had a significant impact on the rebound effect of agricultural water consumption in various regions and prefectures of Xinjiang. Accordingly, the corresponding improvement measures were put forward, including strengthening the adjustment of planting structure, implementing the differentiated implementation and supervision measures to “define land based on water”, accelerating the construction of water conservancy projects, promoting the policy of graded subsidy for water use, and introducing the water-saving policies according to the local conditions.
