High-speed railway (HSR) is an important carrier of China railway passenger transportation. It is of great significance to improve the performance of HSR network. This paper studies the optimization of HSR network with the goal of optimal global accessibility. Based on the degree of stations, clustering coefficient of stations, and other indicators, the topology characteristics of China's HSR network in 2030 are analyzed. The LeaderRank algorithm is used to identify the important stations of HSR network from the perspective of topology. Then the optimization model is established and solved with the goal of optimal accessibility of global network. The results show that Changsha is the most important station in China's HSR network in 2030. Considering the investment restrictions of railway construction, constructing HSR links between Tongliao and Yixian, Datong and Yulin, Wuhai and Wuwei, Mianzhu and Mianyang, and Huanghua and Zibo can maximize the global accessibility of China's HSR network in 2030. The optimization model can improve the performance of HSR network effectively, it also has certain reference significance to construction of HSR network.
