Coal resources have an important strategic position in China's energy production and consumption process,"rich in the north and poor in the south,more in the west and fewer in the east",the phenomenon of mismatched allocation of coal resources,resulting in the mobilization of coal re-sources.Based on the coal transportation data of 31 provinces(Hong Kong,Macao and Taiwan are not included due to the lack of data)from 2011 to 2020,the paper firstly adopts the complex network theory to construct the coal transportation network in China,and then analyzes the node degree,cluster-ing coefficient and other indexes of the network.On this ba-sis,the network efficiency and average clustering coefficient are used to study the network's resistance to destruction,and it is found that the domestic coal transportation network is gradually stabilizing,the"Three Wests"have a strong control over coal,Shandong and other places are gradually becoming the coal transhipment places,and the resistance to destruction of the whole transportation network is gradually increasing.The results of the study can provide reference for the subse-quent network optimization.
