RESUMEN
With the acceleration of urbanization and industrialization, the increasingly prominent contradiction between urban industrial development and urban land supply and demand highlights the need to explore the intricate interplay between the green transformation of urban construction land (GTUCL) and industrial transformation and upgrading (ITU). This exploration carries significant practical implications for fostering the harmonious development of industry and land use and achieving sustainable urban growth. In this study, we constructed evaluation indicator systems for GTUCL and ITU, drawing on the analytical frameworks of "dominant-recessive" transformation theory and "dynamic structure benefit" theory, respectively. We employed an enhanced entropy method, an improved coupling coordination model, and a geographic detector to unveil the coupling coordination relationship, the spatiotemporal evolution patterns, and the driving mechanisms of GTUCL and ITU within the urban agglomeration of the mid-Yangtze River region. The results are as follows: (1) during the research period, the comprehensive index of ITU exhibited substantial growth, increasing from 0.159 to 0.408, reflecting a remarkable 157% surge. Simultaneously, the comprehensive index of GTUCL witnessed an increase from 0.171 to 0.285, signifying a 66.66% upswing, lagging behind that of ITU. (2) The degree of coupling coordination between ITU and GTUCL demonstrated a consistent upward trajectory. It rose from 0.402 to 0.579 by 2020, marking a significant 44.2% increase. The overall development now resides within the stage of coordinated progress, although it remains at a relatively modest level, and the pace of development has moderated somewhat. Regional disparities within the urban agglomeration consistently manifest a trend of initial reduction followed by amplification, accentuating the polarization effect of internal coupling relationships. (3) The spatial differentiation pattern centered around "Wuhan, Changsha, and Nanchang" has become increasingly pronounced. The radiation linkage model following the "core-periphery" paradigm has stabilized further. Nevertheless, the relatively loose spatial connection structure has led to a more conspicuous inadequacy in radiation impact. (4) The core driving factors have transitioned from emphasizing economic development to focusing on technological support. The composition structure has shifted from the initial stage of an "economically sensitive" driving model, which centers on economic development, to the second stage of an "ecologically sensitive" driving model, which prioritizes ecological development.
