Ten key industrial chains in North China's Shanxi province saw revenues totaling 475.17 billion yuan ($65.72 billion) in 2023, with an annual revenue growth of 22.3 percent year-on-year. 

Among them, eight industrial chains achieved double-digit high-speed growth, including the photovoltaic, wind power equipment, and special steel materials chains. 

Last year, Shanxi added six key provincial-level industrial chains concerning new energy storage, waste resources, copper-based new materials, carbon-based new materials, information technology integration applications, and prefabricated construction. Additionally, 17 new "chain-leading" enterprises and 77 core enterprises in the industrial chains were selected.

"Chain-leading" enterprises play a vital role in driving the coordinated development of industry chains. 

For example, Dayun Auto Co based in Yuncheng city has driven the coordinated development of the province's new energy vehicle industry chain, attracting and cooperating with more than 40 suppliers last year. It established the "Dayun-Bosch" joint R&D center and formed strategic partnerships with Bosch to explore the global market.

Taiyuan Heavy Machinery Group based in Taiyuan city entered into strategic cooperation with five major energy companies in 2023, including China Datang Corp and China Resources (Holdings) Co. Its investment scale, about 6 billion yuan, is estimated to drive the heavy machinery industry chain to achieve revenue of 20 billion yuan.
