Node importance is a key factor affecting the overall operation efficiency of a railway freight transportation network (RFTN) that can be measured with the indicators of Hub and PageRank.
Based on complex network theory and the national railway cargo exchange data of China’s provinces, this study constructs an RFTN model with the 31 provinces as the nodes and measures the values of Hub and PageRank for the 31 provinces.
Then, the time evolution law of the importance of the provincial nodes is analyzed comprehensively, and, using a regression model, the influencing factors of the importance of the provincial nodes are identified.
The results show the following.
(1) The uneven distribution of natural resources will affect the spatial changes in the importance of RFTN nodes.
The Hub values tended to cluster around the average, and the economic structure of the output-oriented provinces improved as a whole.
At the same time, the PageRank values of many provinces in the central and western regions significantly increased, and those provinces exhibited more frequent exchanges of goods with other provinces and closer economic ties with other regions.
(2) The traffic fixed asset investments and the population density have the most obvious influences on the importance of the provincial nodes with a positive effect.
In contrast, the railway freight concentration (RFC) coefficient, geographical location (longitude and latitude), and coastal region all have negative effects on the importance of provincial nodes.
The results of this study provide scientific decision-making support for the reasonable establishment and distribution of RFTN hubs in China.
