Spatiotemporal characteristics of the coupling coordination between high-quality economic development and residents' quality of life in the Yellow River Basin

Improving residents' life and enhancing the quality of economic development are the important goals and specific embodiments of high-quality development. We formulate a theoretical framework to facilitate the high-quality development of residents' life and economy, empirically analyze the spatial and temporal patterns of facilitating coupling coordination among 78 cities from 2011 to 2020 by using the coupling coordination model, Kernel Density estimation, ESDM method, and the obstacle degree model, and explore their influencing factors and driving mechanisms. The results show that: ① The coupling degree of cities in the Yellow River Basin is at a high level, and the interactions between the systems are closely linked. ② The coordination degree of the Yellow River Basin as a whole has steadily risen from a mildly dislocated state in 2011 to a state on the brink of dislocation, and the degree of coupling and coordination of each city has fewer extremely high and extremely low values, and more intermediate values. The spatial polarization and agglomeration of the coordination degree is obvious, generally showing the pattern of "high in the east and low in the west", the provincial capital cities are also the agglomeration area of the high value of the coordination degree, while the coordination degree of the other prefectural-level cities is relatively low and balanced in distribution. The coupling and coordination of residents' life and economic high-quality development are affected by many factors, among which the openness dimension of economic high-quality development is the main obstacle, and urban public services and infrastructure construction also affect the coupling and coordinated development of the two to a considerable extent. Therefore, in the future high-quality development, it is necessary to focus on the openness of the economy, improve urban infrastructure and improve public services.
