In the urban agglomeration in the middle reaches of the Yangtze River, the three major cities of Wuhan, Changsha and Nanchang are distributed in the shape of "product", which are the provincial capitals and central cities of the three provinces respectively, and are the "first cities" and "core forces" (for the "three cores") of the three metropolitan areas; And with the three cores as the center, Wuhan metropolitan area, Changsha metropolitan area, Nanchang metropolitan area, a total of three major metropolitan areas (for the "three circles"); The three major metropolitan areas, accounting for more than 60% of the total economic output of each province, are the driving force for the economic development of the surrounding regions, the engine for promoting the economy of the three provinces, and the growth pole of the "rise of the central region" (the "four poles").
The main shaft is in a ring, and the city is in the same belt.
The railway, high-speed railway, expressway and part of the Yangtze River waterway between Wuhan, Yueyang, Changsha, Nanchang, Jiujiang and Wuhan constitute a "ring" fast track across Hunan, Hubei and Jiangxi provinces, and become the main axis of the productive force layout, urbanization and regional economy of the three provinces.

Anonymous users2024-02-09The central belt includes nine provinces and regions: Heilongjiang, Jilin, Inner Mongolia, Shanxi, Anhui, Jiangxi, Henan, Hubei and Hunan. This belt is located in the inland hinterland of China, between the eastern coastal economic belt and the western economic belt. Therefore, the most important feature of this belt is that it is a transitional economic belt.
On the whole, it has a better foundation than the western zone, but it is not as good as the eastern coastal zone. The central belt is relatively rich in resources, such as coal, oil, copper, aluminum, lead, etc
The proven reserves of zinc, tungsten, antimony and other minerals occupy an important position in the country. Hydro and forest resources are also abundant, and many industrial sectors, especially the production of raw materials, occupy a prominent position in the country. The economic foundation is relatively strong, and the transportation is transported.
The transmission is relatively developed, the scientific and technological strength is relatively strong, the historical development is relatively early, and the transmission of information is relatively fast. The economic development of this belt is mainly to speed up the construction of energy and raw material industry, and give play to the role of a national energy and raw material base.
Cities and regions with a relatively high level of economic development should actively develop knowledge- and technology-intensive industries. Vigorously develop agriculture and promote the steady growth of grain and other cash crops. Vigorously develop horizontal economic ties with the eastern and western regions.
It is necessary to receive in a planned way the industries and products that consume energy and raw materials transferred from the eastern belt, actively support the development of the local mining industry, and strengthen the construction of transportation corridors from west to east, so as to make it an important link to promote the gradual transfer of China's economic layout from east to west.
