National Economic Security Evaluation Of Chinese Lead And Zinc Mine

Aiming at national economic security evaluation of lead and zinc mine, it gives a comprehensive study on national economic security evaluation of lead and zinc mine qualitatively and quantitatively on the basis of detailed overview of domestic and foreign research on national economic security and risk assessment. The main contents and conclusions are as follows:First, this paper summarizes the research achievements of domestic and foreign scholars on national economic security evaluation and risk assessment as well in detail.Secondly, it probes the supply and demand of lead and zinc resource in the market, and establishes a model based on BP artificial neural network to predict the consumption of refined lead and zinc from 2019 to 2031. The result shows that although we have abundant lead and zinc resources, the demand for lead and zinc will increase gradually in the coming years and sustainable development of lead and zinc resources is definitely necessary.Thirdly, this paper evaluates the national economic security of lead and zinc rensouces by the method of the variable weight principle and builds a index system which contains 6 level indicators and 15 secondary indicators.
