Why did cities replace ancient countries and governments?

There are several reasons why cities replace ancient countries and governments as administrative divisions:

Changes of political system: In ancient China, counties were the administrative organization form of local political power. With the changes of history, the political system has also undergone many changes. After the founding of People's Republic of China (PRC), the socialist system was established in China, and the administrative divisions were also adjusted and reformed, and a three-level administrative division system of city, county and township was gradually established.

The need of economic development: since the reform and opening up, China's economy has developed rapidly, the process of urbanization has accelerated, and the economic importance of large and medium-sized cities has gradually increased. In order to adapt to the new economic situation and market demand, upgrading some areas into cities is conducive to strengthening the management and development of cities.

Improvement of administrative efficiency: upgrading some areas to cities will help improve administrative efficiency and service capacity. Municipal administrative units are larger than the government and the state, and can better undertake the responsibilities of administrative management and public services.

Regional development differences: the economic, social and population development of various regions in China is unbalanced, and the economic strength and population size of some regions have surpassed those of traditional state and government administrative units. In order to better meet the needs of local development, some areas have adjusted their administrative divisions and upgraded to cities.

It should be noted that the adjustment and reform of administrative divisions in China is a dynamic process, and there may be differences in administrative divisions in different regions. In addition, the adjustment of administrative divisions is also carried out according to the local actual situation and development needs, in order to better meet the needs of social and economic development and administrative management.
