China's second and third tier cities are challenged to build skyscrapers

towering skyscrapers are not worth mentioning in the eyes of most Europeans. "Even if the Empire State building is 10 times higher than today, it still cannot be compared with Florence cathedral" - perhaps the "high-rise fever" will still spread in the city, not because of economic strength, but because of an unspeakable preference. However, the history of urban development over the centuries has proved that the greatness of a city is never due to how high its skyscrapers are. It is only a long-term plan to fear every inch of urban living space. Recently, the news about the construction of skyscrapers in various places has been seen in the newspapers: the 301 meter high "Oriental gate" in Suzhou, which was given the name of "autumn pants tower" by friends, is still fermenting. It is reported that Changsha Wangcheng District, Hunan Province plans to build a 838 meter high skyscraper "sky city", which is 10 meters higher than the current "world's tallest building" Dubai Tower. Before that, it was said that Wuhan Greenland center, which was originally 606 meters high, was going to increase by 30 meters and become "the tallest building in China"... High buildings rose everywhere, with the posture of "the first floor is higher than the first floor". Statistics show that China may have thousands of skyscrapers in five years, four times more than the United States

of particular concern is that most of these skyscrapers under construction or planning are concentrated in second and third tier cities. Does China's urban development really need so many skyscrapers? Whether the speed control of the moving beam of the experimental machine is to set up a "symbol of urban development", or will the huge investment eventually become a flashy "waste"

so "to a higher level"

those huge objects soaring into the sky seem to be becoming "business cards" that urban development can't wait to show: the Guiyang Zhongtian future Ark Project, known as "Guiyang Dubai", is 540 meters high, while the huaxilong building in Huaxi Village and Chongqing International Financial Center in Jiangyin City, Jiangsu Province are 538 meters and 500 meters high respectively. In addition, the 660 meter high Ping'an financial center in Shenzhen is under construction. Zhuhai announced that it would build a 680 meter high Hengqin cross gate CBD landmark, and the 777 meter high Qingdao building has also entered the site selection stage...

according to incomplete statistics, taking the American "buildings over 152 meters as skyscrapers", Chinese Mainland has 350 skyscrapers, 287 skyscrapers under construction and 461 planned skyscrapers. If all goes well, the total number of skyscrapers in China will exceed 1000 in five years, four times that of the United States today

in addition to their height, they are also very "similar" in terms of function and cost: almost without exception, they cover super luxury five-star hotels, international 5A grade office buildings, luxury houses, large shopping centers and other comprehensive business types, with a construction area of millions of square meters and a total investment of billions of yuan... The advertising words are the same: "the landmark of the city", "the symbol of urban development" and so on

looking at the global skyscrapers, most of them are concentrated in international cities with dense population and highly prosperous economy, such as Manhattan, New York, which is full of tall buildings; For example, there are more than 200 buildings over 150 meters in Hong Kong. In contrast, the current round of high-rise fever in China is characterized by the transfer from the original first tier cities such as Beijing, Shanghai and Guangzhou to the second and third tier cities

one "high" conceals all the ugliness

there is no doubt that the construction of skyscrapers in various places has achieved remarkable results in attracting people's attention, but the question is, do these second - and third tier cities really need a "skyscraper"? Can huge investment be translated into practical benefits

it is understood that whether the skyscrapers can obtain income after completion depends on the occupancy rate. Generally speaking, it takes 15 years or more to repay the input cost by collecting rent. The rental rate is often closely related to the proportion of the tertiary industry in the GDP of the city. In Beijing, the proportion of the tertiary industry in GDP is as high as 75%, making the annual absorption of Grade A office buildings by businesses reach 600000 square meters. At the same time, the maintenance cost of super high-rise buildings is generally more than three times that of ordinary buildings, and the high maintenance cost further pushes up the rent

"under the condition that there is a huge gap between the economic development, commercial density and possible agglomeration effect and the first tier cities, it is questionable whether the local economic strength and consumption capacity can withstand the high rent, property and other operations when building high-rise buildings in the second and third tier cities." Zhangsong, Professor of the Department of urban planning of Tongji University, said that some second - and third tier cities are keen to build skyscrapers regardless of local economic conditions. This practice does not conform to market laws and business rules, and it is difficult to obtain benefits or even recover costs. It not only brings hidden worries to future economic development, but also causes huge waste

at the same time, the construction cycle of skyscrapers is long, and they are easily affected by the external economic environment. Once the construction funds fail to keep up in time, it is likely that the capital chain will be broken and finally shelved. Recently, it has been revealed that the "Oriental gate" project, which has attracted much attention, has not been completed for nearly 9 years since it was acquired in 2004. Since the pre-sale was launched in the second half of last year, the sales performance has also been mediocre; The "World Trade Building" in Wenzhou, which started construction in 2001 and was originally planned to be completed in 2008, has not yet been completed. The city landmark is facing the embarrassment of becoming a "uncompleted residential building"

in fact, skyscrapers are often an adventure in urban construction. If its design style and building materials are consistent with the overall tone of the city, it can add color to the unique image of a city. On the contrary, it may cause damage to it and be criticized for a long time. "Therefore, before making the plan for building skyscrapers, it is necessary to carefully demonstrate and repeatedly evaluate to avoid irreparable losses caused by mistakes that damage the overall style of the city. It is even more important to be cautious in the second and third tier cities in China where the economy is not highly developed." Zhang Song pointed out

"high" competition exposes blindness of development

an expert once said that there is no practical difficulty in building super high-rise buildings today. Whether to build skyscrapers or how to deal with them in cities is not an engineering problem, but a social problem

"as a city benchmark, skyscrapers can intuitively display the status and image of the city. In many cases, skyscrapers also attract investment by optimizing the urban environment through land commercial development, but they should match the level of urban development and market demand." According to Qinhui, vice president of the school of public administration of Renmin University of China, according to the measured load and the deformation of the sample, blindly seeking high makes the domestic cities lack characteristics. The skyscrapers in second - and third tier cities are more like a show off of a city's "local achievements" and "image project". They are inevitably reduced to flashy furnishings due to the lack of comprehensive consideration of the city's supporting traffic conditions and economic development level. "In other cases, the difference in building height between different cities and regions is only a few meters, which has become a bargaining chip for local comparison. In addition, it has strong adhesion with paper, metal, wood, cement board, brick wall plastic board, asphalt felt, etc. this phenomenon is very unhealthy." Qinhuimin believes that skyscrapers are blooming everywhere, exposing the blindness of the development of some second - and third tier cities

it should be noted that the temptation of skyscrapers is a common global problem, especially in regions with rapid economic rise, and is also seen as a means to highlight wealth and authority. In 2011, a billionaire in Saudi Arabia also claimed to build a 1000 meter high skyscraper; No one would doubt that the world trade center in the United States under reconstruction will be built higher than before

building skyscrapers is a controversial topic in the world. The focus of the controversy is safety and environment. Experts pointed out that high-rise buildings often have huge potential safety hazards. How to resist various disasters and sudden favorable conditions for China's extruder industry in terms of foreign trade export? Many events and even terrorist attacks are problems that high-rise buildings must face. It is reported that the smoke of a 100 meter high building can spread to the top floor along the vertical tube well in half a minute without obstruction, forming a three-dimensional fire. However, for skyscrapers with glass curtain walls, the reflected sunlight will affect the adjacent environment. The construction of skyscrapers in the city center has also increased the number of people entering and leaving the area and increased the traffic pressure in the area.
