Finding Global Liquefied Natural Gas Potential Trade Relations Based on Improved Link Prediction

Unstable factors such as international relations, geopolitics, and transportation routes make natural gas trade complex changeable. Diversified flexible sources of liquefied (LNG) can guarantee the energy supply security gas-consuming countries. Therefore, it is very important to find potential links help government partners prepare strategically in advance. In this paper, global LNG network taken research object. order fully consider importance nodes influence economic political factors, “centrality degree” “node attraction are added into link prediction algorithm, multifactor coupling carried out. The reliability improved algorithm verified using area under curve (AUC) evaluation index, results analyzed. follows: Trinidad, Russia, Algeria, Nigeria, Angola, Equatorial Guinea (Eq. Guinea) more likely establish new trading relationships with other For all relationships, relations involving above countries be realized within 5 years, while China, India, Japan, South Korea 2 years. import from Taiwan Province Eq. Guinea, America. On basis study, states governments give priority regions when dealing possible crisis.
