Evaluation And Optimization Of The Investment Environment Of Nickel Resources In Overseas Market Based On Entropy Weight-TOPSIS Method

At present,China is facing a major change that has not been seen in a century,and the countries headed by the United States in the world have begun to promote "De-Sinicization".The original model of sourcing raw materials and energy globally before exporting to the world urgently needs to be changed.Novel Coronavirus Pneumonia has accelerated the development of anti-globalization,which is very harmful to the traditional development model.Once the supply chain is cut off,China's related industries will be hit hard.Under the background that domestic nickel resources are far from meeting the demand,it is particularly important to enhance the right to speak,enrich resource acquisition methods,and change the concept of overseas layout.This article takes the research on the overseas investment environment of mineral resources as the core,and on the basis of the domestic and foreign investment environment research,uses the entropy weight TOPSIS method to make a detailed evaluation of nickel resources overseas investment optimization.The main research contents and conclusions are as follows:From the perspective of supply and demand,the conclusion is that the global nickel resources are abundant,but the pattern of supply and demand is unbalanced,and China's domestic supply is far from meeting demand.The global nickel resource reserves,production,consumption and demand have been sorted out and analyzed from time and space,and the global supply and demand situation of nickel resources are fully held in hand.Using literature reading and expert survey methods to screen evaluation indicators,an evaluation index system for nickel resources overseas investment was constructed.From two perspectives of scholars and research institute,this article systematically analyzes the factors affecting nickel resources' overseas investmentenvironment,and identifies reasonable evaluation indicators,which are five first-level indicators including resource environment,infrastructure,politics and law,economic environment and international relations,as well as 20 second-level indicators such as reserves,Railway mileage,GDP growth rate and geographic distance.From the three dimensions of resource reserves,production and exports,seven countries with excellent investment environment were selected.Through the established entropy weight TOPSIS evaluation model,this article analyzes the weight of the index in detail at first,then evaluates the five sub-environments of each country,and finally evaluates comprehensive investment environment of the seven country.The results show that: resources and political law at the first-level indicators have the highest proportion.Exporting resources,reserves,and government administrative efficiency at the second-level indicators are the main factors affecting the overseas investment of nickel resources;the overall investment environment of various countries is generally developing well,but the spatial and temporal differences are significant;different countries have different advantages in sub-environment.Finally,the comprehensive priority of overseas investment of nickel resources in China is as follows: Indonesia,Australia,Philippines,Russia,South Africa,Cuba and Brazil.
