ABSTRACT: In order to study the nodes importance and its evolution process of the railway network of SREB
(Silk Road Economic Belt), we construct the network (RNSREB) based on Graph Theory, which focuses
on the time intervals according to actually railway network, railway project under construction
and the national railway network of medium-and long-term plan. The algorithms for vital
nodes evaluation are analyzed, the evaluation method on nodes importance of RNSREB is proposed,
the quantized values of each node are calculated with Pajek, and TOP20 core nodes of the
network with different coefficients and time intervals are determined respectively. Then the evolution
process of TOP20 critical nodes with 4 periods is contrasted and analyzed. It is indicated
that some vital nodes newly discovered (Geermu, Maduo, Ruoqiang) should be concerned.
