Research on the Evolution Law of International Coke Trade Network——Based on Complex Network Theory
As an important industrial raw material,the international trade relationship of coke is closely related to the international economic situation.For the healthy and stable sustainable development of China's coke trade,this paper constructs a weighted international coke trade network with the help of international coke trade data between 2013-2022 using the complex network method,the nodes of the international coke trade network are the participating countries of coke trade,the edges of the network are the relations between the import and export coke trade,and the weight of the network is the volume of the import and export coke trade,so that we can study the evolution law of the international coke trade network with a macro outlook.The evolution law of international coke trade network is studied from a macro perspective.The results show that:the international coke trade network is getting more and more ambitious;the trade relationship between countries is getting closer and closer;China and Germany have stronger control over the coke trade;India,Germany and Brazil are the core coke trade importers;and Poland,China,the United States and the Czech Republic are the core coke trade exporters.
