Evaluation of Ecological Efficiency of Coal Industry Under Resource and Environment Constraints and Its Influencing Factors

HUANG Wan-hua;LU Ying;School of Management,Wuhan Institute of Technology;  
Through the review of relevant literature and theoretical analysis,this paper constructed the eco-efficiency evaluation system of coal industry composed of resource efficiency index and environmental efficiency index,using the DEA method to measure the ecological efficiency,resource efficiency and environmental efficiency of the coal industry respectively. And then the Tobit model was constructed to study the influencing factors of the ecological efficiency of the coal industry. The results showed that the resource efficiency,environmental efficiency and ecological efficiency of the coal industry were generally low,especially resource efficiency was the main factor restricting the ecological development of coal industry. RD investment intensity,the use of foreign capital and ownership structure of the coal industry could improve the ecological efficiency,while the external supervision was negatively correlated with ecological efficiency,and the impact of energy consumption structure on ecological efficiency was not significant.
