Abstract

The role of energy for the developmental process of nations is a known fact due to being crucial input for any phase of production of goods and services. That’s the reason why countries that are rich in energy resources also have strategic power in terms of the international trade of these resources. On the other hand, it becomes important to provide energy security for countries that are resource-poor. Although green energy has become preferred one, fossil fuel energy keeps its place as one of the most used energy resources. That's why in this study it is aimed to determine major providers and users of coal as a type of fossil fuel energy resources. It is vital to investigate the structure of global coal trade structure to determine the weaknesses and strength of supply and use of coal. Network approach provides a holistic view to the system analyzed and presents more realistic (high-degree) indicators to analyze it. In this study, global trade network of coal is analyzed from 2000 to 2017 via network analysis. Changing structure and evolution of global coal trade has been revealed via some topological parameters which are specific to complex networks such as density, clustering, assortativity/disassortativity, centrality and degree distribution.
