In order to explore the current status of sustainable development of mining enterprises in China in recent years, static and dynamic analysis was performed for ecological efficiency of mining enterprises in 11 different sub-sectors in China from 2012 to 2020, in which SBM-DEA model with undesirable output taken into consideration was adopted in combination with GML index. And regression testing was also conducted in combination with Tobit model for the influencing factors for ecological efficiency. Results show that during the sampling period, the ecological efficiency of mining enterprises was generally trending up, but there was some difference in the efficient frontier, and great difference between each sub-sector. It is found that the technological advancement is the main driving factor for improving ecological efficiency, which is also positively correlated with high degree of interaction with outside world, but negatively correlated with environmental regulations. At last, as for improving ecological efficiency of mining enterprises, some recommendations are proposed for the state, mining sector and mining enterprises.

为探究近几年我国矿业企业的可持续发展现状,采用考虑非期望产出的全局SBM-DEA模型和GML指数对2012-2020年我国矿业企业11个细分行业的生态效率进行静态和动态分析,并结合Tobit模型对生态效率的影响因素进行回归检验。结果显示,样本期内矿业企业生态效率总体呈波动上升态势,且较有效前沿面存在一定差距,不同行业之间差距显著;技术进步是提升生态效率的主要驱动因素;对外开放程度与矿业企业生态效率显著正相关,环境规制与矿业企业生态效率呈显著负相关。最后,从国家、矿业行业以及矿业企业三个视角给出提升矿业企业生态效率的政策建议。
