| With the deepening of global economic integration,the strength of transnational economic connection has been increasing,international trade becomes one of the important forces to promote economic growth in the world.International trade of goods has increased the degree of economic dependence between countries,if one country's economic changes,other countries will be affected through international commodity trading and capital transactions,the country's influence cannot be ignored.Especially in recent years,with the "One Belt and One Road" construction,the trade contacts between China and other countries are becoming more frequent.China is gradually entering the center of the world stage and playing an irreplaceable role in global trade.In this environment,it is very significant to calculate China's position and influence in the global trade chain.At present,the study of China's trade situation mostly from the view of Chinese trade structure,the international division of labor,the international status,while the research from the quantitative analysis of China's trade influence is very few.On the basis of previous studies,this paper analyzes the pattern of global commodity trade from the perspective of global trade network,and analyzes the structure and evolution of China's global commodity trade pattern in recent ten years,and then measures China's global trade status and influence from a quantitative perspective.First,this paper based on the bilateral trade data published by the United Nations Department of Trade,selected the top 20 countries(regions)of global trade flows,and compiled the Global Commodity Flow Matrix(G-CFM).Secondly,based on G-CFM,The paper analyzes the structural characteristics of the global commodity trade network by using the social network analysis method,and analyzes the status of China in the global trade network.The paper analyzes the structure of the global commodity trade network by using the social network analysis method.Finally,based on the basic idea of the input-output table multiplier model,the trade import-pull effect,export-promotion effect and comprehensive influence effect index are compiledaccording to G-CFM,and the trade pull,promotion and comprehensive effect of China on a country and the whole world are analyzed And analyzes the influence and evolution of China's commodity trade in the world through the comparison of the effects of trade between countries.Based on the above research,we get the following conclusions: The overall pattern of the major countries in the global trade network is relatively stable.China,the United States and Germany are the core members of the world trade,but the global trade flows are not completely concentrated in the core countries.To participate in the global commodity trade chain.China's trade position in the world has steadily increased year by year,China,United States,Germany,has become the world's core trade country.China's trade import and export changes on the United States,Germany,Japan and other countries of the import and export promotion effect is very obvious.From the perspective of global trade,China's trade impact has steadily increased year by year,has become the world's largest export-driven effect of the country,the second largest import effect of the country,the overall impact on global trade has became the world's second. |
