First of all, the acceleration of urbanization has promoted cities to replace national capital. With the rapid development of industrialization and urbanization, cities have become economic centers, and the population and wealth potential are concentrated in cities. A city is an important political, cultural, scientific, artistic and entertainment center, and also an important tourist destination. State capitals are usually historical and traditional towns, lacking modern facilities and market characteristics, which limits the development of economy and population.

Second, political and management perspectives need to change. The state capital is a temporary administrative organization managed by the state government. Its duty is to coordinate all government agencies and services of the country, and to manage and maintain the political, economic and social stability of the country. However, with the unique nature and characteristics of each city, the municipal government can better meet the local needs and management, thus realizing the development and progress of the city. By cooperating with local business, cultural and community stakeholders, municipal government leaders can better implement policies and plans according to local needs and different stages of development.

Finally, the democratic system has also promoted the development and growth of the municipal government. Under the modern democratic system, the government should be closer to the people. This means that the municipal government plays a more important role, because the municipal government has closer ties with the people. It is easy for people to reflect their concerns and questions to the municipal government and get faster answers, while it may take longer for the state government to solve these problems. Therefore, the city replaces the state government in order to better reflect and meet the needs of the people and further develop to the bottom government.

In a word, it is a historical necessity for cities to replace the national capital. The modern urban system is becoming more and more complex. The scale and population growth of the city force the municipal government to take on more responsibilities, meet various challenges and provide people with needs. From the economic and political point of view, the municipal government can better manage and develop urban life and economy. In addition, with the development of democratic system, the municipal government, which is closer to the requirements, plays a more important role and is superior to the state government in management and service.
