【 摘 要 】

As an industrial power, China has become increasingly problematic in terms of resource consumption and serious environmental pollution. Encouraging the utilization of industrial solid waste resources is a necessary way to achieve economic and environmental sustainability. Based on the new improved DEA model, this paper studies the utilization efficiency and influencing factors of industrial solid waste resource utilization in 31 regions of China in 2017. The research results show that the average efficiency of China's industrial solid waste resource utilization is at a relatively high level, which is significantly higher than that in 2010; the investment amount of industrial waste treatment in most areas is rationally utilized; nearly half of the areas have excessive storage of industrial solid waste; there is little difference in scale efficiency between the remaining 30 regions except Tibet, but there is a significant difference in pure technical efficiency. Finally, this paper proposes suggestions for improvement from the perspective of coordinating economic, social and environmental sustainability.
