摘要：

Transportation is an important link in natural gas import and export trade, and a systematic evaluation on the transportation safety of imported natural gas is of great significance to ensure the continuous and effective supply of natural gas energy. China's evaluation index system of transportation safety of imported natural gas was constructed by selecting 14 indexes in terms of supply side safety, transportation process safety and receiving side safety. A safety evaluation model was established using principal component analysis (PCA) and K-means clustering analysis. The transportation safety situation of China's imported natural gas was analyzed. The transportation safety of China's imported natural gas was influenced more by 14 indexes, including political stability of gas source countries, number of major gas source countries, diplomatic relations with gas source countries, length of overseas gas pipelines, annual transportation of pipeline gas, number of LNG terminals, receiving and unloading capacity of LNG terminals, natural gas external dependence, annual LNG transportation, number of maritime accidents, transport capacity supply of self-owned fleet, natural gas reserve/production ratio, import price of natural gas, and number of pirate and armed robbery attacks. The transportation safety of China's imported natural gas experienced four states during 2006-2020, i.e., unsafe state (2006-2008), less safe state (2009-2011), relatively safe state (2012-2016) and safe state (2017-2020).
