Abstract: Waste produced in the process of exploitation and utilization of mineral resources will have a certain effect on the ecological environment.This paper uses C2 R model of data envelopment analysis(DEA),a DEAP-2.1platforms to calculate the eco-efficiency value of exploitation and utilization of mineral resources,which takes the 11cities in Hebei province as examples.And it concludes that five cities are DEA efficient and six cities are DEA inefficient.Eco-efficiency inefficient areas are mainly located in southern Handan,Xingtai and east of Tangshan.We have made eco-efficiency optimization design of exploitation and utilization of mineral resources basing on the DEA inefficient areas.And have concluded that to improve the eco-efficiency of exploitation and utilization of mineral resources we can either reduce labor force,capital investment,or improve the technology input efficiency of mineral mining.And it also can be optimized by selecting output path of reducing waste emissions.
