Identification of Global Oil Trade Patterns:An Empirical Research Based on Complex Network Theory
Due to the impact of contradictions between supply and demand of oil resources,geopolitical risk and oil price fluctuation,etc.global oil trade patterns become increasingly complex,which has become one of the most important factor affecting every countrys energy strategy and economic development.In this paper,a global oil trade core network is constructed to analyze the overall features,regional characteristics and stability of the oil trade using complex network theory.The results indicate that:(1)The global oil export core network displays a scale-free behaviour,in which the trade position of nodes presents obvious heterogeneity and the hub nodes play a bridge role in the formation process of the trade network.However,the trade position of nodes in the import network is relatively balanced.(2)The current global oil trade network can be divided into three trading blocs which correspond,respectively,to three main oil-consuming areas,including the South America-West Africa-North America trading bloc,the Middle East-Asian-Pacific region trading bloc,and the former Soviet Union-North Africa-Europe trading bloc.Geopolitics and diplomatic relations are the two main reasons for this regional oil trade structure.The stability of the South America-West Africa-North America trading bloc is highest compared with the other two trading blocs.(3)The global oil trade network presents a robust and yet fragile characteristic,and the impacts of trade interruption always tend to spread throughout the whole network even if the occurrence of export disruptions is localised.
