How to use push-pull theory to explain the urbanization process?

The urbanization process curve reflects the general law of urbanization development, that is, a flattened "S"-shaped curve (as shown below). This is the result of the simultaneous action of many dynamic mechanisms, of which push-pull theory is one. Therefore, it is inappropriate to use push-pull theory alone to explain the urbanization process curve.

Several dynamic mechanisms:

1. Push-pull theory - rural areas push people outward, while cities attract people to flow in.

2. Agglomeration theory-can be understood as a Matthew effect.

3. Capital circulation theory - This is a little complicated and can be understood like this: urban expansion is the result of the development of capitalism.

Background introduction

In the 1960s, American scholar E.S. Lee proposed a systematic theory of population migration - the "push-pull theory." He divided the factors affecting migration for the first time and divided it into two aspects: "push" and "pull". He believes that the former is a negative factor because these factors encourage immigrants to leave their original place of residence; the latter is a positive factor because these factors attract immigrants with the desire to improve their lives to move to new places of residence.

The particularity of my country’s national conditions determines the difficulty and urgency of transferring my country’s rural surplus labor force. Since the 1980s, with the continuous deepening of rural reform, especially the stabilization and improvement of the household contract responsibility system, the enthusiasm of farmers has been mobilized, and social production has been further liberated.
