In this paper, to study the static and dynamic structure features of Beijing metro network, complex network theory is used for the first time. Based on the structure of Beijing metro network in 2015, metro network sample is built. The paper analyzes the static structure features of metro network by computing characteristics like degree and degree distribution, betweenness centrality, average path length and so on. And, for the first time, section flows of Beijing metro is combined in static network topology. And it also analyzes the dynamic features of the network by computing characteristics like node strength and its distribution, weighted node betweenness centrality and node strength correlation and so on. Thus, the paper explains the interaction between the various factors and the impact of Beijing rail network structure, providing some guidance suggestions for the construction and operation of the rail transit in the future.
