城市人口疏散可能适得其反

Urban Population Evacuation Maybe Counterproductive

随着收入水平不断提高,人们对于服务消费的数量、质量和多样性的需求也进一步提高,这使得中心城区的区位优势日渐加强。自从20世纪80年代以来,发达国家的大城市就逐渐出现了人口重新回到中心城区的现象,逆转了之前所谓“郊区化”的趋势。研究发现,在人口众多的特大超大城市建造高楼,提高人口密度,反而能够缓解拥堵,原因恰恰在于,人口密度的提高其实减少了服务生产者和消费者之间的距离。不仅如此,高人口密度还可以提高公共交通的利用率,减少人们对于私家车的依赖。

With the increasing income,people's demand for quantity,quality and diversity of service consumption has been further increasing,which makes the location advantage of the central city more and more obvious.Since the 1980s,large cities in developed countries have seen a gradual return of the population to central urban areas,reversing the previous trend of so-called"sub-urbanization".Studies have found that constructing tall buildings in mega-cities with large population and increasing population density can alleviate congestion,because coincidentally the increase in population density actually shortens the distance between service producers and consumers.Moreover,high population density can also increase the use of public transportation and reduce people's dependence on private cars.
