Coupling coordination and influencing factors analysis of high-quality development of "resource-population-industry" in the Yellow River Basin

Ecological protection and high-quality development in the Yellow River Basin has become a major national strategy. Coupling resources, population and industries systems to coordinate high-quality development is an important way to achieve this strategic goal. The paper analyzes the connotation of high-quality development of "resource-population-industry", and builds an evaluation index system on this basis. The entropy weight method, coupling coordination model, spatial autocorrelation model, decision laboratory method and interpretive structural model method were used to explore the comprehensive level, quality development of resources, population and industry in 55 prefecture-level cities along the Yellow River Basin from 2015 to 2021. Coupling coordinates the spatiotemporal evolution process and its fundamental influencing factors. Research shows: ① The comprehensive development level of resources, population and industries systems in the Yellow River Basin has shown a steady upward trend; ② The degree of coupling and coordination among the three is generally low, but the overall development trend is benign, at the same time, the spatial characteristics of "high in the east and low in the west" are present; ③ The coupling coordination degree of "resource-population-industry" system in the Yellow River Basin shows a strong positive spatial correlation, "high-high" agglomeration areas are mainly concentrated in the downstream areas of the basin, and "low-low" agglomeration areas are mainly located in the upstream areas of the river basin; ④ Among the evaluation indicators, the proportion of education expenditures in fiscal expenditures, the intensity of environmental regulation, the proportion of secondary and tertiary industries in GDP and the proportion of science and technology expenditures in fiscal expenditures are fundamental indicators that affect the high-quality development of "resource-population-industry" in the Yellow River Basin factor. Based on the coupling relationship of the high-quality development of the "resource-population-industry" system and the identified key influencing factors, corresponding strategic suggestions are put forward, in order to provide scientific theoretical support and decision-making basis for the high-quality development of the Yellow River Basin.
