Why should we transfer a lot of money to build a mountainous Chongqing?

At present, the central government has given great support to the western region. On the one hand, this is the continuity of policy; On the other hand, it is really necessary. China is a whole with a vast depth. Even if there is no threat of war, we must achieve coordinated development. In the next few decades, the population in the west and north will be less and less, and will gradually shift to big cities. Moreover, the better the infrastructure such as transportation and education in the western region, the faster the brain drain will be (this is an interesting paradox). In the end, investment in these areas will be idle and abandoned.

Chongqing is rich in water resources. The two big rivers and golden waterways in Chongqing, not to mention the abundant water resources, are very important to modern cities. Cities with the theme of Zhengzhou and Hefei are short of water, and the scale of cities is bound to be limited by water resources. Moreover, Chongqing belongs to the upper reaches of the Yangtze River, and there is basically no major flood. Even if the two rivers rise to historical extremes, the losses to Chongqing will not be particularly great.

Topographically, although Chongqing has complex terrain, its geology is stable and its stratum is hard. The stable rock stratum makes the construction cost of Chongqing very low. The so-called cost is 100 times that of plain cities, but the construction cost is lower than that of soft alluvial plains, which is a wrong proposition. Especially in the construction of high-rise buildings and subway facilities, it is easier to reflect.

Geographically speaking, Chongqing is the throat of the whole Sichuan Basin. The Sichuan Basin where Chongqing is located is a very unique geographical unit in the traditional Han Dynasty. It is closed and rich. Although there are abundant products around, it is difficult to walk around the mountain. Because land transportation is very difficult, water transportation is particularly important to Sichuan Basin. The water system of Sichuan Basin is centered on Chuanjiang River, and three tributaries cover the whole Sichuan Basin. At the intersection of the three tributaries and the Yangtze River, Yibin, Luzhou, Guojiao and Chongqing, the first cities of the Yangtze River, were born respectively. Chongqing, located downstream, is the throat of this passage. The whole Tianfu Sichuan has a population of more than 100 million, which is its hinterland. It is the bridgehead connecting Sichuan Basin with the Central Plains, and the only place where waterways pass. It is natural to build a city here.

Summarize; The rise of Chongqing is due to the port development brought by geographical advantages and the leap-forward development achieved by occupying the natural danger of the basin during World War II. As for the disadvantages of inconvenient urban transportation, it has gradually faded in modern industrial civilization. On the contrary, for modern building engineering, stable rock structure will reduce the difficulty of construction design.
