Ecological protection and high-quality development in the Yellow River Basin has become a major national strategy, and the coupling coordination of economic growth, industrial development and ecology in this area is becoming a research hot spot. This paper analyzed the coupling coordination mechanism of economic growth, industrial development and ecology in the Yellow River Basin and constructed an evaluation index system of coupling coordination degree. Using the coupling coordination model, the spatial autocorrelation model and grey relational model, this paper analyzed the space differences and time differences of the coupling coordination degree of 62 cities in the Yellow River Basin and their driving factors from 2012 to 2018, And the GM (1, 1) gray prediction method was used to predict the coupling coordination degree in the short term. The results showed that：① The overall level of economic growth, industrial development and ecology in the Yellow River Basin had shown a steady trend, and there were no significant differences in the speed of development. However, the coupling coordination of them was seriously out of coordination, and the coupling coordination of ecological protection and high-quality development in the Yellow River Basin had not yet reached a coordinated level,② The coupling coordination degree demonstrated significant global and local spatial autocorrelation features. The global spatial auto-correlation was positive and the convergence features were obvious. (3) The forecast results showed that the coupling coordination degree remained generally stable and coordination had not been reached during the forecast period in this area. The rate of improvement was relatively slow. Finally, a support system incorporating organizational guarantee, spatial governance, policy guarantee and institutional mechanism was established for economic growth and ecological protection in the Yellow River Basin. It is expected that this paper can provide a theoretical basis and lay a certain scientific decision-making foundation for the ecological protection and high-quality development in the Yellow River Basin, [ABSTRACT FROM AUTHOR]

In order to explore the coupling degree and interactive stress between ecological environment and economic development of the Yellow River basin and provide reference for the ecological protection and high-quality development decision-making of the basin, This paper analyzed the relationship between the ecological environment and economic development of nine provinces (regions) in the basin from 2007 to 2017 by using coupling coordination and interactive stress model. The results show that in terms of time series, the coupling coordination between the ecological environment and economic development of the Yellow River basin is in a serious maladjustment state in the early stage, and in a good coordination state in the late stage, and it is more and more coordinated in the whole researched period; in terms of spatial pattern, the coordination degree between the ecological environment and economic development of the upper and middle reaches of the Yellow River is higher than that of the lower reaches of the Yellow River in the early stage, and the coordination degree of the upper and lower reaches of the Yellow River is higher than that of the middle reaches of the Yellow River, the relationship between ecological environment and economic development in the middle reaches of the Yellow River needs further adjustment; through the verification of the stress relationship, there is a certain interactive stress relationship between ecological environment and economic development in the Yellow River basin. In the early stage of the study period, the comprehensive index of ecological environment is larger than that of economic development, in the later stage, the comprehensive index of economic development is larger than that of ecological environment and the improvement of ecological environment has a certain lag.
