Urban concentration and rural growth: a two-sector analysis

Area of Science:

• Economics
• Urban Studies
• Economic Geography

Background:

• Urban concentration is a significant global phenomenon.
• Understanding the drivers of urbanization is crucial for policy and planning.
• Existing models may not fully capture the dynamics of urban economic growth.

Purpose of the Study:

• To investigate the underlying mechanisms driving urban concentration.
• To analyze the role of urban scale economies in economic development.
• To model the transition of labor supply dynamics during urbanization.

Main Methods:

• Development of a two-sector economic growth model.
• Analysis of temporary production decisions and optimal labor inputs.
• Modeling of profit reinvestment based on relative profitability.

Main Results:

• The model demonstrates a persistent tendency towards urban concentration.
• Economic transition from unlimited to limited labor supply is shown.
• Urban concentration is indicated as more probable than rural contraction.

Conclusions:

• Urban scale economies are a key factor in persistent urbanization.
• The model provides insights into labor market shifts during economic development.
• Findings suggest a tendency for economic activity to centralize in urban areas.
