The flow of international oil trade from 2002—2010 is selected as sample data. The binary and weighted international oil trade network which include 180 nodes,regard oil trade relations as edges and trade flow as weight are built based on the theory of complex network.This paper studies the evolution of node degree,centrality,degree correlation,node strength and clustering coefficient.In particular,we find that:the capacity of international oil trade system is increasing and the oil trade links between countries become more closely. United States,France,Canada,Germany and the Netherlands have strong ability in controling the oil trade,but the war in Iraq and the financial crisis significantly decrease the United States ability in controling the oil trade.International oil trade network is a disassortative network.The globalization of trade and the appearance of regional organizations is gradually strengthen.More and more oil is needed,but with the decrease in reserves,aging in oil fields and other reasons the world's major oil-producing countries were unable to supply more oil to the international oil market.The war in Iraq and the financial crisis have strong effect on the strength of oil trade relations,but the impact of the financial crisis is less than the war in Iraq.In all,the research displays the overall oil trade development trend and provides our country a new way of choosing suitable partners,making oil policies and reducing trade risks.
