How did Qinghai’s economy change after the communists took control in 1949?

Following the communist takeover in 1949, Qinghai experienced rapid industrial growth and significantly increased attention toward economic development compared to the preceding Republican period.12

Before 1949, the province’s economy was limited, relying primarily on food and animal by-products in centers like Xining and small-scale salt mining in the Qaidam Basin. After 1949, the economy diversified significantly:1

• Industrialization: The government established chemical, machinery, iron, steel, and electrical equipment plants in Xining and other cities.1
• Resource Exploitation: Development focused heavily on the Qaidam Basin, which contains the majority of the province's mineral reserves, including petroleum, natural gas, lithium, and various salts.12
• Infrastructure: Growth was facilitated by the expansion of transportation networks, most notably the 1959 opening of the rail line connecting Xining to Lanzhou, which integrated Qinghai into the national rail system.3
• Energy: The province harnessed its water resources by constructing large hydroelectric-power stations on the upper Huang He, such as those at Longyangxia and Lijiaxia.1
• Agriculture: The region transitioned toward a mixed farming-livestock economy, with vast pastoral lands opened for cultivation.4
