摘要

As the global renewable energy industry (REI) undergoes rapid expansion, the conflict between its land requirements and the scarcity of land resources has become increasingly pronounced. There is an urgent need to explore synergistic pathways for enhancing land use efficacy (LUE). However, existing literature has largely overlooked the relationship between LUE and REI. This study integrates grey relational analysis and the TOPSIS method, a coupling coordination model, the Dagum Gini coefficient, and panel vector autoregression to investigate the spatiotemporal evolution, regional disparity drivers, and bidirectional feedback mechanisms in the coordinated development of these two systems. Key findings indicate that coordination levels have shifted from a near-dysfunctional state to preliminary coordination, forming a pattern characterized by steady development in western regions and accelerated progress in central and eastern areas. Regional disparities in coupling coordination have gradually narrowed, with interregional differences being the primary source of overall imbalance. In terms of interactive effects, the renewable energy industry exerts a stronger positive influence on land use efficiency, exhibiting lagged and asymmetric dynamics. A bidirectional causal relationship exists between LUE and REI across eastern, central, and western regions. Policy interventions should emphasize spatially-guided planning and context-specific promotion of integrated renewable energy applications to foster synergistic development between land resources and clean energy. This study offers a Chinese case study for global energy transition and provides a new pathway for harmonizing LUE with REI.
