Suzhou is one of China's foremost cities for foreign investment due to its proximity to Shanghai and lower operating costs. Major industries include iron and steel, IT and electronic equipment manufacturing, and textile products. After Shanghai, Suzhou possesses the second largest industrial city in China and is home to 27 listed companies. Further sign of its pro-business environment include the success of Kunshan, a county-level city in Suzhou, which manufactured half of the world's 170 million plus notebook PCs in 2009.
Substantial improvements in infrastructure will continue to benefit Suzhou; these include a high-speed railway between Suzhou and Shanghai, a light rail line linking the two cities' subway system, and a Suzhou metro line.
