Textiles, silk, and chemical fibers are traditional industries in Hai'an, and their output value accounts for more than 40 percent of the city's total industrial output. In recent years, Hai'an has been insisting on encouraging enterprises to increase investment in science and technology to improve products, enhance market competitiveness, and promote the high-quality development of traditional industries.
