[Spatial-temporal Distribution Pattern and Dynamic Evolution of the Coupling Coordination Degree Between High-quality...

With the construction industry's continuous progress in high-quality development and ecological resilience enhancement， the coupling and coordination between these two dimensions have emerged as a critical issue for achieving sustainable development. Leveraging panel data from 30 Chinese provinces spanning 2014 to 2023， this study employs an integrated methodology combining the weighting-TOPSIS approach， a coupling coordination degree model， kernel density estimation， the Dagum Gini coefficient， and Markov chain analysis to systematically investigate the spatiotemporal coupling characteristics and regional disparities in the high-quality development of the construction industry and ecological resilience. The results indicate that： ①During the study period， the coupling coordination degree between high-quality development and ecological resilience exhibited an overall upward trend， albeit with significant regional heterogeneity. ②The eastern region demonstrated the highest level of coupling coordination， coupled with the most rapid growth rate， while the northeastern region experienced pronounced growth fluctuations. In contrast， the central and western regions lagged behind the national average in terms of growth. ③Intra-regional disparities gradually narrowed， whereas inter-regional differences remained a persistent challenge for the coupling coordination of the two systems. ④The coupling coordination degree displayed a tendency to maintain its existing state， with spatial proximity effects playing a significant role in enhancing coordination levels. This study advances the theoretical understanding of the coupling coordination mechanism between high-quality development and ecological resilience in the construction sector， offering strategic insights and policy recommendations for fostering regional coordinated development and sustainable transformation.
