Abstract：Under the global trend of green and low-carbon transition,China's mining enterprises face dual pressures of economic growth and ecological protection,which necessitates in-depth research on their green transition efficiency and spatial imbalance.This study takes listed mining enterprises from 2008 to 2024 as samples,constructs a Super-SBM mod-el incorporating desirable and undesirable outputs to measure green transition efficiency,and analyzes regional disparities based on spatial economics.The results show:Policy cycles significantly influence transition efficiency and exhibit a fluc-tuating pattern of"policy-driven—technology lag—institutional restructuring",with comprehensive efficiency ranging between 0.35 and 0.39.Leading enterprises,such as PetroChina(601857),achieved efficiency leaps through clean energy substitution;A"dual paradox"exists between technical efficiency(mean 0.82)and scale efficiency(mean 0.46).While 90%of enterprises are in increasing returns to scale,fragmented resource allocation persists regionally.Spatial heterogen-eity is prominent,with core regions(e.g.,Beijing-Tianjin-Hebei,Yangtze River Delta)driving efficiency improvements in neighboring areas through technology spillovers,while western resource-rich regions lag by over 30%due to technologic-al bottlenecks and insufficient ecological compensation.Policy recommendations include enhancing technical collabora-tion standards,optimizing regional compensation mechanisms,and promoting industrial chain integration to foster bal-anced green transition in the mining sector.
