- W2363088886 abstract "This study explored an approach to assess the efficiency of the iron ore resources development and utilization based on the generalized DEA,which uses a sample unit,generated from the decision-making unit,as reference standard to evaluate the efficiency of decision-making unit,to ensure the consistency of the external environment in the evaluation process.This study selected the investment as the input indicator and the total amount of profit of the mining enterprises as the output indicators,and carried out an empirical study based on the iron ore resources related data of year 2013 of Hebei province,thus obtaining iron mine resources development efficiency differences between parts of the city of Hebei province in 2013,as well as a summary description and assessment of the reasons for the differences.This study provides a scientific approach to regional zoning based on the efficiency.The empirical results show that the method in theory and practice are feasible.This method can effectively meet the estimation and assessment of the iron ore resources development and utilization of zoning based on efficiency,thus providing decision support and reference for enhancing the development and utilization efficiency of the iron ore resources and the development of relevant policies." @default.
