The Coupling Relationship and Driving Factors between Water Resources Utilization and High-quality Economic Development in the Yellow River Basin

Abstract

Taking the Yellow River Basin from 2008 to 2019 as the research object, this paper constructs the index system of water resources utilization efficiency and high-quality economic development, makes a comprehensive evaluation and coupling analysis of them by using entropy method and coupling coordination degree model, and uses geographic detectors to detect the influencing factors driving coupling coordination scheduling. The results show that: (1) The comprehensive evaluation index of water resources utilization rate in the Yellow River Basin shows a fluctuating upward trend as a whole. The water resources utilization rate of the nine provinces of the Yellow River has obvious differences in different years. The water resources utilization efficiency of Gansu is the highest in 2008 and Sichuan is the highest in 2019. (2) The comprehensive evaluation index of high-quality economic development in the Yellow River Basin is increasing year by year, with significant regional differences. The high-quality economic development of Shanxi and Shaanxi was the highest in 2008, and the high-quality economic development level of Henan and Ningxia was the highest in 2019. (3) The coupling degree and coupling coordination degree of the Yellow River Basin and all provinces show an increasing trend. The coupling coordination degree of the whole basin has increased from being on the verge of imbalance to good coordination, especially after 2015. (4) Socio economic factors are the leading factors affecting the coupling and coordination between water resources utilization efficiency and high-quality economic development. Water resources conditions and government financial support also play an important role.
