Abstract: Aiming at the problem of how to evaluate the international petroleum trade relationship more accurately, a network and structural characteristic index quantitative analysis of the relationship is carried out. In this study, the complex network theory was used for network modeling, the structural balance theory was used for quantitative analysis, and the key indexes such as calculated clustering coefficient and degree of balance were used for annual benchmark comparison. The conclusion is that with the increase of the number of traders, especially the number of importing countries, the clustering coefficient of the network becomes larger, the balance degree value increases, the balance of the entire trade network becomes worse, and the trade relationship becomes more tense. This research adopts network and structured way to evaluate the relationship, which is a beneficial attempt to advance the research of oil trade relationship from qualitative to quantitative.

Key words: complex network, structural balance, degree of balance, growing scale-free networks, international petroleum trade relations
