There are also cities with relatively concentrated machinery industries such as Shijiazhuang, Jinan, Fuzhou and Guangzhou. Moreover, the mainland's machinery industry has also initially established a foundation, forming a number of machinery industry bases and cities with a certain scale, such as Sichuan machinery industry base centered on Chongqing and Chengdu, and machinery industry concentration areas centered on Guanzhong and Hanzhong in Shaanxi.
