| Gold mineral resources are national strategic resources,but they are also non-renewable.However,the static guarantee years of the identified reserves and basic reserves of the mineral are decreasing year by year.While the demand for gold is far greater than the supply Through the analysis of the influence degree and efficiency of the influencing factors on the development and utilization of gold mineral resources,this study provides reasonable suggestions for enterprises with lower efficiency,so as to ensure the sustainable development of gold mines.Firstly,this study identifies the influencing factors from the whole industrial chain of gold mineral resources development and utilization.The influencing factors include resource reserves,gold price,development cost,development income,market demand,exploration technology,mining technology,production technology and development pollution.At the same time,corresponding indicators are selected for each influencing factor according to certain screening principles.Secondly,the original data of influencing factors indicators for the thirteen years from 2005 to 2017 are collected through four channels:China Mining Yearbook(2006-2013),Land and Resources Bulletin(2014-2017),National Bureau of Statisties and Hexin Gold.Then the comprehensive influence degree of each impact index is calculated by combining the entropy weight value and correlation analysis of the entropy weight method,and the influence degree of the influencing factors of gold mineral resources is expressed by the size of the comprehensive value.The top three variable indicators of impact degree are production cost,resource reserves,exploration investment.Because the production cost and exploration investment are both factors of development cost.Therefore,in the final efficiency evaluation of this study,the BCC model in DEA model and Malquist index model are mainly used to analyze the economic efficiency of 13 listed companies in 2013-2017,aiming at the development cost respectively.In DEA model,production cost and exploration input are seleeted as input indicators,while total assets,net profit,main business income and production output are selected as output indicators.Through the analysis,we can see that the ratio of companies with optimal development cost efficiency increases year by year.Among them,Zijin Mining,Chifeng Gold and Ronghua Industries have the best relative efficiency at the current level every year.Through the analysis of companies whose efficiency is not optimal at the current level,it is found that in order to improve the non-optimal situation of development cost efficiency,it is necessary to reduce production costs and increase profits at the same timeTherefore,in the first part of the proposal,from the perspective of the degree of impact,in order to promote development and utilization,it is neeessary to increase investment in exploration of various companies.Secondly,from the point of view of improving efficiency,we can reduce costs by setting up cost control group,improving material tracking management system construction and improving incentive and restraint mechanism.We can also increase profits by increasing the scale of assets and expanding the scope of main business mines.Finally,it will promote the sustainable development of gold mines.The above suggestions can be used as a reference for the 13 or more manufacturing enterprises studied. |
