Abstract
Background：The high-quality development in the Yellow River Basin has to be fostered by the coordination of resources, environment, and economy. Therefore, conducting an analysis on the coupling level of resources, environment, and economy in the Yellow River Basin is of major significance to the research on its high-quality development path. Methods：Based on the data of the nine provinces in the Yellow River Basin from 2004 to 2017, a coupling development model is constructed for an analysis of the coupling level in this area and a modeling prediction. A comprehensive evaluation of the development level of Resources-Environment-Economy system and the subsystems in the Yellow River Basin is performed by combining the range change method and entropy weight method. Results：The result shows that despite the rising coupling level of resources, environment, and economy in the Yellow River Basin, the comprehensive evaluation value of the environment subsystem is low, which was merely 0.109 in 2017 and has remained unchanged between 2009 and 2017, resulting in a low coupling coordination degree of Resources-Environment-Economy. In 2017, the coupling coordination degree was only 0.454. The development was on the verge of imbalance and the high-quality coordinated development of the Yellow River Basin has been restricted. The simulated prediction indicates that the coordinated development of Resources-Environment-Economy in the Yellow River Basin can only be realized by overcoming the disadvantages of the ecological and economic systems. Conclusions：When the comprehensive evaluation value of environmental subsystem increases by 0.2 and that of economic subsystem increases by 0.1, all the systems are just coordinated; when the comprehensive evaluation value of each subsystem reaches 0.65, the development of the systems of Resources-Environment-Economy in the Yellow River Basin are well coordinated.
