Shenyang is an important industrial center in China. It has been focused on heavy industry, particularly aerospace, machine tools, heavy equipment, and defence, and recently, on software, automotive, and electronics. During the first five-year plan (1951-1956), many factories were built in Tiexi district. At its peak (1970s), Shenyang is one of the top three industrial centers in China (the other two are Shanghai and Tianjin). However, after the 1980s, the heavy industry has declined gradually and Shenyang has become a rust belt city. The economy of the city has revived significantly in recent years, thanks to Chinese government's "Revitalize Northeast China" campaign and the rapid development of software and auto manufacture industries.
Shenyang
The city’s name, Shenyang, literally meaning "the city to the north of Shen River", comes from the Hun River on the city’s south side, which used to be called Shen River. Archaeological findings show that human beings resided in present day Shenyang as early as 7,200 years ago. The City of Shenyang was first established by Qin Kai, a general of Yan in the Warring States period about 300 B.C. It was named as Hou City at that time. It became known as Shen Prefecture in the Jin Dynasty and Shenyang Path in the Yuan Dynasty. During the Ming Dynasty, it became Shenyang Zhongwei.
