Spatiotemporal Evolution and Driving Factors of Synergistic Development Between Urban Resilience and Urban Land Use Efficiency in the Yangtze River Economic Belt

Promoting the coordinated development of urban resilience (Ur) and urban land use efficiency (Ulue) is key to solving regional sustainable development challenges. Based on panel data of relevant indicators from the Yangtze River Economic Belt (YREB) for the period 2011–2024, this study employs the coupling coordination degree model, kernel density estimation, and exploratory spatial analysis tools to analyze the spatiotemporal differentiation characteristics and spatial correlation of the coupling coordination degree between Ur and Ulue (Uucc). And the spatial patterns of Uucc driving factors are investigated using the Geographically Weighted Regression (GWR) method. The results indicate: (1) In terms of the temporal dimension, the Uucc in the YREB shows an upward trend, with its level continuously improving. The number of cities with higher Uucc levels gradually increases, exhibiting multi-center and multi-layered characteristics. (2) In the dimension of space, Uucc exhibits strong spatial correlation. LISA high-value clusters are concentrated in the downstream region of the YREB, while low-value clusters are found in the upstream and midstream regions. The spatial clustering presents a pattern of “large dispersion, small agglomeration”. (3) The driving factors of Uucc display significant spatial heterogeneity. Urbanization, government regulation capacity and technological innovation are the dominant drivers in the downstream region. Urbanization has a significantly positive effect on Uucc, while its impact gradually weakens from the downstream to the midstream and upstream regions. Urbanization and openness level are the dominant drivers in the midstream region. This study provides references for governments to formulate differentiated policy for different regions.
