Dongguan[a] is a prefecture-level city in central Guangdong Province, China. An important industrial city in the Pearl River Delta, Dongguan borders the provincial capital of Guangzhou to the north, Huizhou to the northeast, Shenzhen to the south, and the Pearl River to the west. It is part of the Pearl River Delta built-up (or metro) area with more than 65.57 million inhabitants as of the 2020 census spread over nine municipalities across an area of 19,870 square kilometers (7,670 sq mi).[1] Dongguan's city administration is considered especially progressive in seeking foreign direct investment.[4][who?] Dongguan ranks behind only Shenzhen, Shanghai and Suzhou in exports among Chinese cities, with $65.54 billion in shipments. It is also home to one of the world's largest shopping malls, the New South China Mall,[5] which is seeing increased activity.[6] Although the city is geographically and thus culturally Cantonese in the Weitou form and as well as culturally Hakka in the prefectures of Fenggang and Qingxi, the majority of the modern-day population speaks Mandarin due to the large influx of economic migrants from other parts of China.[7] The city is home to several universities, including Guangdong University of Science and Technology, Guangdong Medical University and Dongguan University of Technology. In the Pearl River Delta region Dongguan was the first urban area where joint production was implemented between village collectives, local Chinese Communist Party cadre, and foreign investors. In the 1990s this type of enterprise accounted for around 20 percent of all foreign direct investments and approximately 50 percent of exports by the People's Republic of China (PRC).[8]
