Shēnzhèn is a major city in the south of Southern China's Guangdong Province, situated immediately north of Hong Kong. The area became China's first—and one of the most successful—Special Economic Zones (SEZs). It currently also holds sub-provincial administrative status, with powers slightly less than a province.
Shenzhen's modern cityscape is the result of the vibrant economy made possible by rapid foreign investment since the institution of the policy of "reform and opening" establishment of the SEZ in the late 1979, before which it was only a small village. Both Chinese and foreign nationals have invested enormous amounts of money in the Shenzhen SEZ. More than US$30 billion in foreign investment has gone into both foreign-owned and joint ventures, at first mainly in manufacturing but more recently in the service industries as well. Shenzhen is now considered one of the fastest-growing cities in the world.
Being southern mainland China's major financial centre, Shenzhen is home to the Shenzhen Stock Exchange as well as the headquarters of numerous high-tech companies. Shenzhen is also one of the busiest container ports in China.
Shenzhen was recently named as one of the 13 emerging megalopolises in China in a July 2012 report by the Economist Intelligence Unit; Supersized cities: China’s 13 megalopolises. The report pinpoints and highlights the demographic and income trends that are shaping these cities' development
