沿黄九省（区）农业用水效率与农业经济发展耦合协调关系研究
Coupling and coordination relationship between agricultural water use efficiency and agricultural economic development in the nine provinces (autonomous regions) along the Yellow River
The coordinated development of agricultural water use efficiency and agricultural economy has become an important part of the high quality development of the Yellow River Basin. The undesired output super efficiency SBM model and the comprehensive evaluation model are used to measure the agricultural water use efficiency and the level of agricultural economic development in the nine provinces (autonomous regions) along the Yellow River, then the coupling coordination degree model and the coefficient of variation method are used to analyze their coupling coordination relationships and spatial differences. The results show that the agricultural water use efficiency and agricultural economic development level of the nine provinces (autonomous regions) along the Yellow River have witnessed overall progress from 2011 to 2019; their coupling degrees are in the primary coupling stage, and the coupling coordination degree has transitioned from the moderate coupling stage to the high coupling stage; the spatial differences of coupling degree are constantly narrowing, and the coefficient of variation of the coupling coordination degree shows the general trend of initial falling and subsequent rising; the degrees of coupling and coordination in different provinces (autonomous regions) are at different stages. Therefore, all regions should adopt development strategies tailored to local conditions, and also pay attention to the coordination between water resources utilization and economic development.
