ABSTRACT
In the context of global sustainable development goals and heightened environmental awareness,
the imperative to evaluate the eco-efficiency of mining becomes paramount. However, the escalated
mining activities result in the generation of wastewater, exhaust gas, and solid waste, posing a threat
to the environment. This study endeavors to assess the mining eco-efficiency across Chinese provinces
by introducing a pioneering assessment index system and framework. The framework incorporates the
non-desired output SBM-DEA model and the Malmquist-Luenberger total factor productivity index
model. To validate the reliability of the model, it is applied to 27 provinces in China. The findings unveil
significant insights: (1) The mining eco-efficiency of Chinese provinces exhibits an overall positive
trend but displays notable spatial variations; (2) East China demonstrates superior technical progress
and overall technical efficiency, while North, Northeast, and Northwest China lag in technical progress
but excel in overall technical efficiency. Notably, non-desired outputs exert an influence on China’s level
of green mining development, particularly in Northeast and Central China. The study recommends that
enterprises shoulder the responsibility of environmental management and mine restoration, enhance
their capacity for innovation in green technology, and expedite the construction of green mines to
augment mining eco-efficiency. These results furnish valuable perspectives and pertinent information
for decision-making related to green mining development, energy structure transformation, and the
implementation of large-scale mining projects.
