Geographical concept: where the Yangtze River enters the sea, the flat and roughly triangular land is formed due to the continuous sedimentation of the silt contained in the river. Wanli Yangtze River rushes to the sea from west to east, and the river is surging down, and the sediment it carries is constantly silting up at the estuary. After thousands of years, it finally forms an open and broad triangular land.
concept of industrial economy: Jiangsu and Zhejiang economic belts with Shanghai as the leading factor. This is the economic sector with the fastest economic development, the largest economic aggregate and the most development potential in China. The GDP in 28 was 5,395.291 billion RMB. US$ 787,712.49 billion. Statistics in 24 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 rapid accumulation of international capital and private capital in the Yangtze River Delta is not only growing in scale, but also strongly promoting the rapid economic development in this region with its unique vitality. According to statistics, from January to September, 23, the GDP of Suzhou, Hangzhou, Wuxi and Ningbo all exceeded 1 billion yuan, with an increase of more than 12% in the same period. The GDP of Shanghai has exceeded 39 billion yuan, with a year-on-year increase of more than 1%. This rapid economic growth, which is 3 to 5 percentage points higher than the national growth rate, has been maintained in the Yangtze River Delta for many years.
On this most fertile land in China, large and dynamic urban agglomerations are constantly rising: Shanghai, a "super giant", ranks first in the country with an annual GDP of over 1, billion yuan; "Heavyweight giants" Suzhou, Hangzhou, Wuxi, Ningbo and Nanjing have an annual GDP of 2-5 billion yuan; "Little Giants" Shaoxing, Nantong, Changzhou, Taizhou, Jiaxing, Xuzhou and Wenzhou have an annual GDP of more than 2 billion yuan. The county economy, which brings richness and layering to the "Yangtze River Delta" metropolitan area, is very competitive. In the ranking of the top 1 counties and cities in China announced in November 28, seven counties and cities (districts) in the Yangtze River Delta entered the top ten. The rise of county economy makes it possible for the cities in the Yangtze River Delta to be contiguous and urbanized.
This group of economic giants has directly attracted the attention of many world-class economic giants. At present, more than 4 Fortune 5 companies have settled in this area, among which more than 2 have set up regional headquarters and China headquarters in Shanghai, and 81 have invested in Suzhou alone, with 188 investment projects. According to incomplete statistics, the contracted utilization of foreign capital in this area has reached nearly 15 billion US dollars. The Yangtze River Delta has become a powerful magnetic field to attract international capital and technology.
In the metropolitan area of "Yangtze River Delta", enterprises, as the main force of economic development, lead the way. There are nearly half of the top 1 counties in the national economy, nearly 1 industrial parks with annual industrial output value exceeding 1 billion yuan, and thousands of giant enterprises including Wanxiang Group, Jinshan Petrochemical, Yangzi Ethylene, Volkswagen, Shanghai Bell and Dongfang Communication. Most of these enterprises are large in scale, strong in strength, and their product market share ranks among the best in the country, and occupy a place in the international market.
Shanghai is one of the international economic, financial, trade and shipping centers, which drives the development of the Yangtze River Delta region and the whole Yangtze River basin. The 21 World Expo has brought Shanghai a good opportunity in all aspects, and Shanghai is striving to become a "world city". Shanghai's powerful radiation and the rapid development of its neighboring "water-advantaged" cities have made all cities in Jiangsu and Zhejiang provinces aware of the importance of regional cooperation. All other cities are trying to find their own urban positioning and find opportunities for urban rise in the flow of funds, information, talents and commodities.
connecting with Shanghai, realizing * * * and promoting economic integration in the Yangtze River Delta have become the knowledge of local governments in the Yangtze River Delta region. Suzhou: near the water tower, with four-sided layout; Wuxi: integrate into integration and seek new development; Nanjing: echoing Shanghai and radiating the surrounding area; Hangzhou: connecting with Shanghai, dislocation development. Cities around the "Yangtze River Delta" invariably regard the linkage with Shanghai as an important strategy. Taking the planning and construction of road and bridge transportation network as an opportunity, the Yangtze River Delta is building a "three-hour economic circle".
the trend of great integration has already begun. The projects in Jiangsu, Zhejiang and Shanghai have involved many fields, such as transportation, tourism, exhibition, talents, science and technology, information, trademark, credit, quality inspection, environmental protection, etc., and high-level cooperation and linkage such as industrial planning, policies and regulations, and financial services are being discussed from simple to profound. And "connecting with Shanghai" has gone beyond the meaning of a simple investment platform.
The integration of the Yangtze River Delta is a microcosm of China's economic globalization after China's entry into WTO. The existence of a large number of foreign companies has greatly enhanced the degree of economic internationalization in the Yangtze River Delta region, and the whole Yangtze River Delta is becoming a "world factory", and products made in China are constantly moving from here to the world.
The Yangtze River Delta is the largest region in China's opening to the outside world. It has a solid industrial base, developed commodity economy and convenient land and water transportation, and is the largest foreign trade export base in China.
the Yangtze river is one of the economic open areas in China. The delta basement is a part of the Yangtze paraplatform, and the Himalayan tectonic movement interrupted the settlement. During the Quaternary neotectonic movement, the crust and sea level frequently rose and fell. After the last transgression, the sediment carried by the Yangtze River continued to deposit and began to develop deltas in the estuary.
due to coriolis force, the main river keeps turning to the right, which makes the estuary sand group merge into the north bank in turn. The sandbars and sandbars formed in Hongqiao period, Huangqiao period, Jinsha period, Haimen period and Beisha period formed Yancheng, the largest alluvial plain city on the north bank of the Yangtze River today, and the counties of Hanjiang, Taixing, Jingjiang, Rugao, Rudong, Nantong, Haimen and Qidong. Now Chongming, Changxing, Hengsha and other sand islands near the estuary will also be merged into the north bank according to this law. Jiangkou sand mouth also extends synchronously.
the north bank sand mouth extends to the northern boundary of the present delta, with a ground elevation of 6-8m.
The south bank sand mouth extends eastward through Jiangyin, Taicang, Waigang and Maqiao, with a ground elevation of about 4.5-6 meters, and reaches Hangzhou Bay after connecting with the north bank of Qiantang River. The shallow water bay inside the sand mouth was silted up and became the predecessor of the ancient Taihu Lake. Since then, the shallow bay has been silted up and gradually evolved into a low plain with lakes and rivers crisscrossing. The coastal area outside the south bank sand mouth has been continuously silted into a coastal plain.
There are a series of residual hills scattered in the delta with an altitude of 1-3m, most of which are composed of Devonian sandstone and Carboniferous and Permian limestone, and a few are composed of Yanshanian granite and trachyte.
