The concept of "multi-tier cities" has long been deeply rooted in the hearts of the people and has become a common indicator for people to measure the level of urban development. However, there have been different opinions on the criteria for dividing "several tier cities".
1.Official Standards: Vague Guidelines
Officially, there is no clear standard for dividing "several tiers of cities". The National Bureau of Statistics (NBS) has issued the "City Size Classification Standard", which mainly divides cities according to indicators such as urban population size, proportion of non-agricultural population, and economic development level, but does not clearly correspond to "multi-tier cities".
2.Market standard: multi-dimensional consideration
In practice, some research institutions and ** classify cities according to multi-dimensional indicators such as economic development level, population size, science and education culture, transportation convenience, quality of life, etc., forming a more common concept of "first-tier city", "new first-tier city" and "second-tier city".
3.Typical features: Comparison of first-, second-, and third-tier cities
First-tier cities: highly developed economy, huge population, gathering a large number of high-quality resources, and having national and international influence in the fields of finance, science and technology, culture and other fields. Typical representatives: Beijing, Shanghai, Guangzhou, Shenzhen.
Second-tier cities: ** Rapid economic development, strong scientific, educational and cultural strength, playing an important leading role in regional economic development. Typical representatives: Hangzhou, Nanjing, Tianjin, Wuhan, Chengdu, etc.
Third-tier cities: ** The economic development is relatively backward, but it has certain development potential and is an important support for regional economic development. Typical representatives: Shenyang, Xi'an, Qingdao, Changsha, Zhengzhou, etc.
4.Significance of grading: reference value and limitations
The division of "several tier cities" has a certain reference value, which can help people understand the level and characteristics of urban development, but it also has certain limitations.
The indicator system is not perfect: **The existing classification criteria for "several tier cities" mainly focus on indicators such as economic development level and population size, and do not take into account factors such as science, education, culture, and quality of life.
Development dynamic changes: The economic and social development of a city is a process of dynamic change, and the division of "several tier cities" is often relatively static, which is difficult to reflect the new changes in urban development in a timely manner.
5.Future prospects: a more scientific urban classification system
In the future, a more scientific and perfect urban classification system should be established to reflect the level and characteristics of urban development more objectively and comprehensively.
Improvement of the indicator system: On the basis of the existing indicator system, add indicators such as science, education, culture, and quality of life to more comprehensively reflect the level of urban development.
Dynamic monitoring and evaluation: Establish a dynamic monitoring and evaluation mechanism, regularly classify cities, and reflect new changes in urban development in a timely manner.
The division of "several tier cities" is not only a tool to understand the level of urban development, but also an important reference to promote the balanced development of cities. The establishment of a more scientific and perfect urban classification system is of great significance for promoting high-quality urban development.
