Changzhou's economy, with a GDP exceeding one trillion yuan, is anchored by three pillar industries: new energy, rail transit equipment, and intelligent manufacturing.
The new energy sector is the city's most dynamic growth driver. Trina Solar, headquartered here since 1997, has shipped over 100 GW of solar modules globally. The Changzhou Photovoltaic Industrial Park hosts a complete supply chain from silicon ingot production to module assembly. The city also manufactures lithium batteries and electric vehicle components.
Rail transit equipment manufacturing is the second pillar. CRRC Changzhou produces electric locomotives, high-speed train carriages, and subway cars for domestic and international markets. The facility has supplied trains to over 20 countries including Australia, Argentina, and Ethiopia.
Robotics and intelligent manufacturing represent Changzhou's future. The Changzhou Robotics Park houses over 100 companies specializing in industrial robots, collaborative robots, and automation equipment. New materials, particularly carbon fiber and advanced composites, form a growing sector.
The traditional textile and garment industry, while smaller than before, has upgraded to technical textiles and functional fabrics. Tourism centered on Dinosaur Park and Tianmu Lake adds billions to the local economy.
