Its full line operation has further improved the road network structure in Gansu, Ningxia and other western regions, greatly facilitating the travel of people along the line, and is of great significance in promoting regional coordinated development and comprehensively promoting rural revitalization. The Yinchuan Lanzhou high-speed railway connects Yinchuan, the capital of Ningxia Hui Autonomous Region, and Lanzhou, the capital of Gansu Province.
