Why can't the Pearl River Delta or Beijing-Tianjin-Hebei build a world-class urban agglomeration?

The Pearl River Delta is called "Pearl River Delta" and "Greater Pearl River Delta". In recent years, the concept of "Pan-Pearl River Delta" has been put forward, including nine provinces of Guangdong, Fujian, Jiangxi, Hunan, Guangxi, Hainan, Sichuan, Guizhou and Yunnan, and two special administrative regions of Hong Kong and Macao, referred to as "9+2" for short. This shows that the rapid rise of the Pearl River Delta and its huge expansion space are expected to become a world-famous giant economic zone. The development characteristics of the Pearl River Delta are: the rapid urbanization of rich areas has been realized; Formed an "export-oriented" development model; It presents an "explosive" urbanization dominated by rural urbanization; It presents a multi-center, high-intensity and agglomeration urban agglomeration development form; Outline the "circle" economy and urban development characteristics of the inner, middle and outer circles; There is a special spatial structure of "non-city and non-countryside" in the urban-rural fringe.

The Yangtze River Delta, near the East China Sea, is the largest estuary of the Yangtze River in China. The Yangtze River Delta urban agglomeration is the region with the highest degree of urbanization, the densest urban distribution and the highest level of economic development in China. The Yangtze River Delta includes 15 cities, including Shanghai, eight cities in Jiangsu Province and six cities in Zhejiang Province. Later, Taizhou City, Zhejiang Province joined the Yangtze River Delta Urban Economic Coordination Committee, which was called "15+ 1". It takes Shanghai as the center, Nanjing and Hangzhou as the sub-centers, including Yangzhou, Taizhou, Nantong, Zhenjiang, Changzhou, Wuxi and Suzhou in Jiangsu, Jiaxing, Huzhou, Shaoxing, Ningbo and Zhoushan in Zhejiang, *** 15. It has jurisdiction over 74 counties and cities, and is linked by Shanghai-Hangzhou, Shanghai-Nanjing Expressway and several railways, forming an organic whole. The Yangtze River Golden Passage flows through 29 major cities, leading the Yangtze River Delta to the inland hinterland, and is an important gateway for Chinese mainland to connect with the world. The Yangtze River Delta has made full use of international and domestic resources and markets, making it one of the most dynamic areas in China. The development characteristics of the Yangtze River Delta are: forming a comprehensive industrial base; Urbanization presents structural development; The comprehensive strength of the city leads the whole country, and the characteristics of the circle are obvious; The level of urban industrialization is relatively high; Urban logistics conditions have been formed; The strength of urban education science and technology is strong and high-level talents are intensive; The living standard of urban and rural residents is relatively affluent, leading the country.

The Bohai Rim region is located in the northern part of the eastern coast of China, and leads to the northern hinterland of China through the Beijing-Tianjin-Tangshan urban belt. With its special geographical location, dense industries and cities, it is an important gateway to the world in the northern coastal areas of the mainland. 1986, Bohai Bay Economic Zone led by Beijing and Tianjin came into being. Generally speaking, in a narrow sense, it refers to the coastal economic zones around the Bohai Sea, mainly Liaodong Peninsula, Shandong Peninsula and Beijing-Tianjin-Hebei. Its goal is to build a world-class city with Beijing and Tianjin as its dual cores. On a larger scale, the framework of "5+2" strategic cooperation pattern has been formed, namely, Hebei, Shanxi, Liaoning, Shandong and central and eastern Inner Mongolia, and Beijing and Tianjin. The development characteristics of the Bohai Rim region mainly include: the formation of important industrial intensive areas and large urban agglomerations in China; The development of regional planning started late, and the regional economic development is obviously backward compared with the Pearl River Delta and Yangtze River Delta. Make every effort to build a new platform for regional economic development in the Bohai Economic Circle and establish a new mechanism for "win-win" regional coordination and cooperation.

The advantages of the Yangtze River Delta are good business atmosphere, good business environment, high degree of internationalization, strong brand consumer market and strong private economy. At the same time, the structure of a song with two wings (with Shanghai, Nanjing and Hangzhou as the sub-centers) is the most reasonable, and domestic economists put forward two concepts: Wenzhou model and Sunan model. The advantage of the Pearl River Delta lies in its open mind, relatively easy communication with investors from Hong Kong and Taiwan, and convenient geographical location. It has established institutional and cultural conditions that match the market economy. Pearl River Delta enterprises, represented by some listed companies in Shenzhen, have become excellent blue-chip companies with the most investment value in China. The advantage of Bohai Rim is that it is rich in natural resources, closest to the national policy decision-making center, strong in heavy industry foundation and cheap in rent. Economists have analyzed that among the three economic circles, the Yangtze River Delta has the lowest growth rate and the Bohai Rim has the highest. However, according to purchasing power parity, in 2006, the Yangtze River Delta has surpassed kanto region, headed by Tokyo, and is the largest economic zone in Northeast Asia (Japan, South Korea, including Hong Kong, Macau and Singapore). By 2020, the economic scale of the Yangtze River Delta will be twice that of the Kanto Economic Circle, and the Pearl River Delta will surpass the Kanto area in the same year. Although the Yangtze River Delta is rich, it lacks inclusiveness. In Jiangsu, there are disputes between southern Jiangsu and northern Jiangsu, and in Zhejiang, there are disputes between eastern Zhejiang and western Zhejiang. Shanghai, the leading city, is "famous" for its xenophobia, so there are some difficulties in language communication between Jiangsu, Zhejiang and Shanghai. Relatively speaking, Shenzhen is much more tolerant, because many people in Shenzhen are immigrants, but language is also a big obstacle. Bohai Rim should be the most tolerant and the easiest to communicate in language. Now Bohai has become a new hotbed of entrepreneurship. As Shandong's GDP exceeds Jiangsu's, it has been suggested that the Bohai Sea is approaching the Pearl River Delta at an alarming rate. When China manufacturing began to transform to China, China was no longer the first choice for large foreign multinational companies, and China's cheap labor status was gradually replaced by India, so the investment fever of multinational companies gradually cooled down.
