Which metropolitan areas will have opportunities in the future?

65438 +0 Shanghai Metropolitan Area: the "strong core" of the Yangtze River Delta urban agglomeration, radiating the surrounding metropolitan areas. 1) The GDP of Shanghai metropolitan area reached 9 1 trillion yuan in 20 18, which was higher than that of nine cities in the Pearl River Delta. The industrial layout was basically optimized with the idea of "R&D in Shanghai and production outside". 2) From "one core, five circles and four belts" to Shanghai metropolitan area, it is a "strong core" to give full play to Shanghai's role as a central city, build the Yangtze River Delta urban agglomeration and radiate the surrounding metropolitan areas. Shanghai metropolitan area has included most metropolitan areas of Suzhou, Wuxi, Changzhou and Ningbo, and Jiaxing and Huzhou in Hangzhou metropolitan area. 3) Shanghai Metropolitan Area actively breaks down the barriers of administrative divisions and builds a multi-level rail transit of "trunk line+intercity+city area+urban rail" to lay the foundation for an integrated metropolitan area.

No.2 Beijing metropolitan area: from single center to deconstructing non-capital function, are the three northern counties expected to be placed under Beijing? 1) Relieve the function of Beijing's non-capital, and change from a single-center radiation with a big pie to a dense multi-group pattern. Beijing metropolitan area can be roughly divided into three layers of gradient radiation: one is six central cities, the other is several new cities in sub-centers and urban development zones, and the third is ecological conservation areas and areas around Beijing to the east and south of Beijing. 2) Beijing has high-tech industries represented by scientific and technological innovation and modern service industry, but the problem of job-residence balance is the most prominent in the country. 3) The area around Beijing needs to make up for the lack of undertaking industries and the commuting efficiency is low. There are endless rumors about the coordinated development of the three northern counties in Langfang and Tongzhou, the sub-center of Beijing, and the transfer to Beijing.

Third place Shenzhen-Guan Hui metropolitan area: a paradise for young immigrants to start businesses. Is it possible for Shenzhen, a city with big economy and small land, to annex Dongguan? 1) With the rapid growth of population and economy in Guan Hui metropolitan area, the "front shop and back factory" industry is shifting step by step, which is a paradise for young immigrants to start businesses. 2) The (3+2) mechanism of Shenzhen-Guangzhou-Huizhou Economic Circle promotes the integrated development of Shenzhen-Guangzhou-Huizhou, and the integration of "enclave economy" and rail transit enhances Shenzhen's radiation-driven capacity. 3) Shenzhen is a city with a large economic population and a small land area, with a total area of only 1.997 square kilometers, namely 1/8, 1/3 and 1/4 in Beijing, Shanghai and Guangzhou respectively. It is possible to solve the shortage of development space through the adjustment of administrative divisions for a long time, but it is subject to the overall development of Guangdong Province.

The Fourth Guangzhou-Foshan-Zhaocheng Metropolitan Area: Greater Bay Area Modern Manufacturing Center in Guangzhou-Foshan-Zhaocheng. 1) The total economic output of Guangfo is similar, with "IAB (new generation information technology, artificial intelligence, biomedicine) +NEM (new energy, new materials)" innovative industries and advanced manufacturing industries as the main industries, and Zhaoqing undertakes the industrial transfer of Guangfo. 2) It will take time for Zhaoqing and Guangfo to integrate into the economic circle of Guangfo and Zhao from the same city as Guangfo. Zhaoqing's GDP in 20 18 was 220.2 billion yuan, which was110 in Guangzhou. Per capita GDP is only 35% of Guangzhou's and 42% of Foshan's. 3) The urbanization of Guangzhou and Buddhism has been basically realized, and the cost of living and industrial transfer have spawned a large number of cross-city commuting needs. From 2065438 to July 2008, the number of people living across cities in Guangzhou, Foshan and Zhaoqing reached 744 1 10,000, of which Guangzhou and Foshan accounted for 60.6% of the total size of the four cities.

No.5 Nanjing metropolitan area: the economy is strong in the east and weak in the west, and the eastern city of Anhui benefits. 1) The economy of Nanjing metropolitan area is strong in the east and weak in the west, and Nanjing leads the industrial chain from high to low. Nanjing's GDP in 20 18 is GDP10.3 trillion yuan; Yangzhou, Zhenjiang, Huai 'an and Wuhu are all building advanced manufacturing centers at 300-600 billion yuan; Maanshan, Chuzhou and Xuancheng are all below 200 billion yuan, mainly undertaking industrial transfer in the east. 2) Nanjing metropolitan area is the first planned inter-provincial metropolitan area in China, and the eastern cities of Anhui benefit from the development of urbanization with Nanjing. Nanjing is closer to the four cities of Anhui in the metropolitan area than Hefei, the capital of Anhui. 3) Forward-looking layout of the rail transit system in Nanjing metropolitan area, together with roads, airports and port groups, to build a comprehensive transportation hub demonstration area.

6th Chengdu Metropolitan Area: A land of abundance, Chengdu has a high concentration of population and economy, low urbanization rate and large space around it. 1) Chengdu is still in the stage of becoming bigger and stronger and attracting surrounding resources, with a high concentration of population and economy. The resident population of Chengdu in 20 18 accounts for 6 1% of the five cities in the metropolitan area, and the GDP in 20 18 accounts for 75%. The number of listed companies with A+H shares and the number of invention patents granted account for 94% and 93% respectively. 2) The four cities around Chengdu have low urbanization rate and large urbanization space, and are expected to develop with Chengdu in the future. The urbanization rates of Deyang, Meishan, Ziyang and Ya 'an in 20 17 were all between 4 1%-5 1%, far below the national average of 58.5%. The population of metropolitan area has great urbanization potential. 3) The high-speed railway between Chengdu and surrounding cities will reach 1 hour in half an hour, and it is expected to form an intercity railway loop in the future, but the current traffic connectivity still needs to be improved.

No.7 Hangzhou metropolitan area: private economic paradise, internet economic highland, hinterland expansion to the west. 1) The private economy of Hangzhou, Jiahu and Shaosi in Hangzhou metropolitan area is developed, and the Internet economy is leading. New members Quzhou and Huangshan are expected to undertake related industries. 2) The eastern part of Hangzhou metropolitan area lacks development space, and the western part expands its economic hinterland. Facing the squeeze of Shanghai metropolitan area and the competition of Nanjing metropolitan area, Hangzhou metropolitan area chose to move westward, and Quzhou and Huangshan formally entered the circle. Xuancheng, Shangrao and Jingdezhen are also candidate cities, among which Xuancheng has been included in Nanjing metropolitan area. 3) Hangzhou, Jiaxing and Huzhou have realized the "half-hour high-speed rail circle" and "1 hour traffic circle", and the high-speed rail will help Quzhou and Huangshan integrate into the metropolitan area.

No.8 Chongqing metropolitan area: the inland open highland, the population growth rate of the new district is close to the main city, and the industrial homogenization and innovation are insufficient. 1) Chongqing Metropolitan Area has gathered 65% of the population, and created 72% of GDP with 35% of Chongqing's area. Both the main urban area and the new urban development area have strong population industrial agglomeration ability. The average annual growth rate of resident population in Xincheng Development Zone from 20 1 1 to 20 17 is 1.9%, which is close to 2. 1% of the main urban area. 2) Chongqing metropolitan area is an inland open highland, and its industrial homogeneity and lack of innovation ability are shortcomings. There is homogeneous competition within the high-end development platform systems in Chongqing, Chengdu and Chongqing. 3) The interconnection level of rail transit in Chongqing metropolitan area needs to be improved urgently. At present, the regional railways are far from meeting the commuting needs of the main city and the periphery.

No.9 Wuhan Metropolitan Area: It is more pragmatic to narrow the "circle" and the industrial chain extends outward. 1) From "1+8" Wuhan metropolitan area with a radius of150km to Wuhan metropolitan area with a radius of 80km, the planning of a smaller metropolitan area is more feasible. 2) Wuhan industrial chain extends to surrounding cities along the development corridors of Huang Huang, Wuxian, Wuxian and Hanxiao, and improves the functional layout and industrial system of the metropolitan area. 3) The construction of high-speed rail and Ezhou Airport will strengthen the water, land and air transportation hub, and the intercity railway network will be connected in series with Wuhan metropolitan area.

10 Changsha-Zhuzhou-Xiangtan metropolitan area: the central part rises, the urban areas are adjacent, and the "half-hour traffic circle" develops in an integrated way. 1) The three cities of Changsha, Zhuzhou and Xiangtan have strong industrial complementarities and good industrial synergy, and are one of the important strategic fulcrums for the rise of Central China. The three cities jointly have national policy platforms such as the Changsha-Zhuzhou-Xiangtan "two-oriented society" comprehensive supporting reform pilot zone and the Changsha-Zhuzhou-Xiangtan national independent innovation demonstration zone. 2) The urban areas of the three cities of Changsha, Zhuzhou and Xiangtan are not more than 40 kilometers apart, and the geographical integration is convenient, and the voice of merger has never been cut off. In recent years, the proposal that Changsha, Zhuzhou and Xiangtan merge to apply for a national central city has been widely circulated, but the possibility of realization is extremely small. 3) High-speed rail, intercity railway, expressway and urban trunk roads are connected in series to form the "half-hour traffic circle" of Changsha-Zhuzhou-Xiangtan metropolitan area.
