Abstract:

Taking the nine provinces and autonomous regions within the Yellow River Basin as research focus， we constructed an evaluation framework for ecological environment and common prosperity. Employing a coupling coordination model， we quantified the coupling coordination between these two systems for the period spanning from 2000 to 2019. We classified and delineated the various types of coupling coordination and examined their spatiotemporal evolution characteristics. The findings reveal that the ecological environment and common prosperity within the Yellow River Basin exhibited an overall upward trend from 2000 to 2019. Notably， the downstream ecological environment in the Yellow River Basin remained relatively stable， while the ecological conditions in the upstream and middle reaches generally improved. A distinctive "hook-shaped" trend was observed in shared prosperity， characterized by an initial decrease followed by an upswing in the upper， middle， and lower reaches. Furthermore， the coupling coordination in the upper， middle， and lower reaches displayed a "concave" development pattern with varying degrees of stability. While the coupling coordination development in the upper and lower reaches was promising but marked by instability， the middle reaches exhibited lower but consistent coupling coordination development. Since 2000， various provinces within the Yellow River Basin experienced periods when the coupling coordination between ecological environment and common prosperity teetered on the brink of imbalance. However， with the exception of Gansu Province， most provinces witnessed a significant acceleration in coupling coordination between ecological environment and common prosperity over the past two decades. This trend reflects a geographical distribution pattern characterized by "higher in the north and south， and lower in the central regions." This research serves as a basis for providing policy recommendations to facilitate the integrated development of the ecological environment and common prosperity within the Yellow River Basin.
