Where do the Yangtze River Delta and the Pearl River Delta refer to?

The Yangtze River Delta is a concept with triple significance.

Geographical concept: where the Yangtze River enters the sea, a flat and roughly triangular land is formed due to the continuous deposition of sediment contained in the river. The Wanli Yangtze River flows into the sea from west to east, and the river surges down, and the sediment it carries is constantly deposited in the estuary. After thousands of years, it finally formed an open and broad triangular land.

Concept of industrial economy: the industrial economic belt in southern Jiangsu and northeastern Zhejiang with Shanghai as the leader. This is an economic field with the fastest economic development, the largest economic aggregate and the greatest development potential in China. Statistics in 2004 show that the Yangtze River Delta region accounts for 1% of the national land and 5.8% of the national population, creating 18.7% of GDP, 22% of national fiscal revenue and 18.4% of foreign trade exports.

The Yangtze River Delta Metropolitan Area refers to the urban belt with Shanghai as the leader, which consists of Jiaxing, Hangzhou, Shaoxing, Ningbo, Zhoushan in Zhejiang and Suzhou, Wuxi, Zhenjiang and Nanjing in Jiangsu.

Pearl River Delta

The concept of "Pearl River Delta" originated in the early 1990s. At the end of 1990s, the concept of "Greater Pearl River Delta" appeared on the basis of "Little Pearl River Delta". In 2003, the concept of "Pan-Pearl River Delta" was put forward. Up to now, the "Pearl River Delta" actually includes three concepts: small Pearl River Delta, big Pearl River Delta and pan-Pearl River Delta, which are different from each other but closely related.

(A) "Little Pearl River Delta"

1994 10. On October 8th, the concept of "Pearl River Delta" was formally put forward for the first time, and the Guangdong Provincial Party Committee proposed to build the Pearl River Delta Economic Zone at the Third Plenary Session of the Seventh Congress. The "Pearl River Delta" was originally composed of seven cities including Guangzhou, Shenzhen, Foshan, Zhuhai, Dongguan, Zhongshan and Huizhou, and a part of Huizhou, Qingyuan and Zhaoqing, commonly known as the Guangdong Pearl River Delta. Later, the scope of the "Pearl River Delta" was adjusted to an area consisting of nine cities along the Pearl River, namely Guangzhou, Shenzhen, Foshan, Zhuhai, Dongguan, Zhongshan, Huizhou, Jiangmen and Zhaoqing, which is commonly known as the "Pearl River Delta" or "Little Pearl River Delta". The "Little Pearl River Delta" covers an area of 24,437 square kilometers, less than 14% of the land area of Guangdong Province, with a population of 42.83 million, accounting for 6 1% of the population of Guangdong Province. In 2003, the total GDP of the "Little Pearl River Delta" reached11450.9 billion yuan (1383.5 billion US dollars), accounting for 10% of the national GDP.

(2) "Greater Pearl River Delta"

"Greater Pearl River Delta" has two different concepts, one refers to "Little Pearl River Delta" and Hong Kong and Macao, and the other refers to Guangdong, Hong Kong and Macao. At present, the so-called "Greater Pearl River Delta" refers to the region composed of Guangdong, Hong Kong and Macao. The "Greater Pearl River Delta" covers an area of 18 1 10,000 square kilometers, with a total registered population of 86.79 million and a total GDP of $328.7 billion in 2003. From the perspective of economic scale, the "Greater Pearl River Delta" is equivalent to 1.2 times that of the Yangtze River Delta.

(3) Pan-Pearl River Delta

"Pan-Pearl River Delta" includes nine provinces of Fujian, Jiangxi, Guangxi, Hainan, Hunan, Sichuan, Yunnan, Guizhou and Guangdong, and two special administrative regions of Hong Kong and Macao, with close economic and trade relations. The Pan-Pearl River Delta covers an area of 2.006 million square kilometers, with a total registered population of 456.98 million and a total GDP of 5,260.57 billion yuan (US$ 635.6 billion). Among them, 9 provinces and autonomous regions account for 20.9% of the country's total area, 34.8% of the country's population and 33.3% of the country's total GDP.
