Since its opening, the Qinghai-Xizang Railway has tightly connected Xizang's market with the unified national market, reducing the cost of production and living materials in Xizang, allowing the vast farming and pastoral population on the plateau to benefit directly. A large number of unique plateau products have been continuously exported through the Qinghai-Xizang Railway. At the same time, building materials and daily necessities have been delivered to Xizang, not only meeting the needs of Xizang's social and economic development but also enriching the material needs of the local people.
