  "New Lenba" and "Beijing -Shanghai", if these global cities are divided into two categories, how to divide?Lu Ming, a well -known economist, threw a concept of "inclined city" to his colleagues at home and abroad on the 20th.The more typical "inclined city", the skyscrapers in the city center are lined up. The "average height" from the urban area to the suburbs is significantly reduced, just like New York and Shanghai;Beijing.Interestingly, the Lu Ming team looked at the problem of congestion from the perspective of "inclined cities" and the space structure from the large city.

  Regardless of altitude, from the city to the countryside, it is usually "middle height and low surroundings", like a righteous waist triangle.Under the influence of multiple factors including history, culture, war, etc., the layout and form of some urban buildings are a blunt corner triangle, and the "slope" of the two beams is relatively small and closer to flat.In other cities such as Shanghai, this triangle is relatively large, and it is fast to form the gradient distribution of population density, showing the appearance of "sharp -horn triangle".

[Urban congestion is not related to population density]

  在国际城市排名中,2008年起每年发布一次的最新“全球实力城市指数(GPCI)”方面,2023排名靠前城市分别是breaking news website:伦敦、纽约、东京、巴黎、新加坡、阿姆斯特丹、首尔、breaking news website迪拜、墨尔本, Berlin, Shanghai, Beijing, and Hong Kong followed closely.On the same day, experts at home and abroad conducted international academic discussions at Shanghai Normal University, focusing on "new challenges and opportunities for high -quality development in global cities in the world."This was disclosed by Shikawa Hiroshi, a director of the Institute of Strategic Research of the Mori Memorial Consortium and Honorary Professor of the Meiji University in the GPCI index.

  Jiefang Daily · Shangguan News reporter learned that the index consists of six major parameters including economy, research and development, cultural interaction, livability, environment and accessibility, forming a "hexagonal" radar map.The six "horns" in Shanghai are very balanced, without obvious short boards and long boards.Among them, the "average driving speed" and "the convenience of taking a taxi or cycling" have declined.

  From the perspective of blockage alone, the "tilt city" is a compact city, and the population of population is very significant. Will it be more prone to "urban diseases" such as congestion?As a special professor -appointed professor of the Shanghai Jiaotong University of Communications and Executive Dean of the China Development Research Institute, Lu Ming did not think so.

  Its team uses trafficShowing the development pattern of urban agglomerations and central cities, it is found that every time the urban population is doubled, the commuting time is only 10.54%, which is only 2.23 minutes more, which has changed people's usual cognition.In fact, in the super metropolis, which is based on the service industry, its productivity and consumer service industry, regardless of quantity, quality and diversity, must always gather towards the central urban area. Naturally"Pull up.In his opinion, there is not much positive correlation between urban congestion and population density, and the "separation of vocational and residential", especially the model of living in the suburbs and work in the city, is one of the biggest reasons for the traffic jam of traffic peaks.

[Accelerate the return to the "most metropolitan city in the city"]

  Stones from other hills, can learn."New York's" Silicon Lane 'is on Manhattan Island, only one or two kilometers from Wall Street; the same is true of the science and technology city in East London, and it is a step away from the London Financial City. "Professor Liu Jianghui, dean of Shanghai Normal University, bluntly said thatThe layout of the scientific and technological resources of the city is returning to the "most urban metropolitan city" from the "urban suburbs".

  It can be said that in the global city index overall downward, scientific and technological innovation has become the core driving force of the current and future global cities that has shaped its international competitiveness and enhance its global resource allocation energy.At present, the Shanghai Global Urban Research Institute has conducted systematic research on the global urban index, and is signed with international colleagues to jointly build a "Globalization and World Urban Research Network" China Office and the European Branch of the European Institute of Comparison.It is worth mentioning that the excellent business environment has also become standard in global cities. The global cities in China represented by Shanghai and Beijing are particularly dazzling. The business environment score is higher than that of old European and American cities such as New York and Paris.

  Perhaps many people are worried that the population is getting more and more and the city is getting bigger, but the slowdown in urbanization growth is even more worried about urban scholars.Data show that in 2022, the urbanization rate of the permanent population in the country reached 65.22%, but only 0.5 percentage points increased from the level of 64.72%in 2021, and the growth rate in 2021 was 0.83 percentage points."The growth rate of urbanization reached a new low, showing the characteristics of cliff -like decline." Professor Zhang Lei, School of Public Management of Renmin University of China, said that in the high -quality development of cities, tolerance cities update must ensure low -cost living space.
