Research On Trade Network Evolution Trend Of Arctic Route Economic Circle

Global warming has led to accelerated melting of Arctic sea ice,thus setting off a new round of exploration of the Arctic route.The Arctic route connecting Northeast Asia and Northwest Europe and eastern North America as potential shortest route possible sharing by the traditional route of the flow of goods by sea,has huge potential economic value.In the context of the Arctic route opening,the Arctic route will become the new gathering place for international shipping,it is impetus to change the pattern of world seaborne,the opening of the Arctic routes would have grievous impact on the trade business of the areas the Arctic routes affected.China’s foreign trade is very dependent on maritime transport,and China and the Arctic route economic circle in many countries is an important partner to study the Arctic route economic circle trade network evolution for China to develop the Arctic route development strategy to provide a reference.This paper first elaborates the background and significance of the research,the research progress at home and abroad,and the research methods and framework of this paper.Then,this paper introduces the opening of the Arctic route and the Arctic route,gives the definition of the economic circle of the Arctic route,selects 30 countries as the research object,the state as the node,the trade link between the countries,the country Import and export trade volume as the weight,build the Arctic route economic circle trade network,study the Arctic route economic circle in 2002-2015 trade pattern of evolution.We mainly analyze the degree of centrality,the center of the important countries in the 14 years,and the centrality of the important countries.Then we analyze the agglomeration subgroups in 30 countries,observe which countries are closer and trade relations are closer.Finally,we calculate the core degree of the countries in the economic circle of the Arctic route,divide them into core countries,semi-marginal countries and marginal countries,and then analyze the trends of the core countries in the core countries.Through the above analysis,the Arctic route economic circle trade trend is finally obtained.The results show that with the continuous development of the economy,the trade relationship between the countries of the Arctic route economic circle is closer,the trade between countries still does not get rid of the influence of the geopolitical factors,the core of the United States is declining year by year,and China has long been the core country And the core degree is on the rise,but still have a certain gap with the United States,the need to further strengthen foreign trade,enhance their core position.
