The Baoshan area became a significant hub for Shanghai’s iron and steel industry starting in the late 1970s, when local iron and steel companies began constructing new facilities in that region north of the city.1

This development led to the establishment of the Shanghai Baosteel Group Corporation, which has grown to become one of the world’s largest enterprises since the beginning of the 21st century. This expansion was part of a broader evolution of Shanghai's manufacturing sector, which had previously focused on integrating iron and steel production with the city's machine-manufacturing industry.1
