From the perspective of overall economic strength, the Yangtze River Delta region accounts for 10 of the 35 cities with the strongest economic strength in the country; this region accounts for half of the top 100 counties with comprehensive strength in the country. The scale, technical level, brand advantages, etc. of steel, petrochemicals, automobiles, textiles and other products in the Yangtze River Delta region are higher than those in the Pearl River Delta region. More than 400 of the world's top 500 companies have settled here, and the total number of contracted foreign investments has exceeded US$150 billion. In recent years, there has been a striking phenomenon in the economic development of the Yangtze River Delta region, that is, the region is gradually forming economic integration. All regions have consciously recognized Shanghai's leading position and begun to integrate and allocate their own resources. Taking the initiative to integrate with Shanghai, different urban positioning and division of labor have been formed. In terms of foreign investment, the current reality is: manufacturing goes to Jiangsu and Zhejiang, commercial services go to Shanghai; small and medium-sized enterprises go to Jiangsu and Zhejiang, and large enterprises go to Shanghai. This kind of urban cluster with different functions and positioning provides a very good choice and market for foreign investors. From the perspective of urbanization development level, the Yangtze River Delta region is not only higher than the Pearl River Delta region, but also formed an urban belt with Shanghai as the center and Nanjing, Suzhou, Hangzhou, and Ningbo as sub-centers. The urban system is complete in levels and the quality of urban planning is high. , the city positioning is relatively accurate, and the planning and development of provincial capital cities and cities, counties, districts and towns are relatively coordinated. Hangzhou Mayor Mao Linsheng once painted such a blueprint: "The future transportation plan will connect the Yangtze River Delta region into a large metropolitan area. You can live in the Jiuxi Rose Garden in Hangzhou at night and take the high-speed train or maglev train the next morning. Go to work in Shanghai Jin Mao Tower." It's hard to say that this is a joke, but no matter what, it reveals that "Paradise City" is also willing to be a sub-central city in the southern wing of the Yangtze River Delta. In comparison, there is still a certain gap in the Pearl River Delta in terms of the quality of urban planning, the rationality of layout, and the development of urban functions, and the market is not as radiant as the Yangtze River Delta. Compared with the aggressive upward momentum of Zhejiang and Jiangsu, the Guangdong Provincial Bureau of Statistics summarized Guangdong's current economic development trend as "leading in total volume and narrowing the gap." This conclusion is reached after a horizontal comparison of the statistics in the first half of last year between Guangdong and four economically developed provinces and cities: Shanghai, Jiangsu, Zhejiang and Shandong. The so-called "leading in total volume" means that Guangdong still has a scale advantage and its economic aggregate still ranks first in the country. In particular, its foreign trade exports increased by 20.9% over the same period last year, taking the lead; the so-called "narrowing of the gap" means that Guangdong's economy The growth rate is in the middle range, the growth rate of some economic indicators is too low, and the gap with latecomers is gradually narrowing. After more than ten years of rapid growth in the Pearl River Delta region, the original conditions for rapid economic growth have gradually weakened, and it is urgent to create new conditions to promote its own development - this may be the biggest challenge the Pearl River Delta faces today. At the same time, there are more and more signs that the Yangtze River Delta region has become one of the most dynamic and promising economic regions not only in China but also in the world, and is recognized as one of the most dynamic and promising economic regions in the world after London and Paris. The sixth metropolitan agglomeration.
