Question 1

What is the main principle of Weber's Least Cost Theory?

Accepted Answer

The main principle of Weber's Least Cost Theory is that industries choose locations that minimize total production costs, considering three primary factors: transportation costs (for raw materials and finished goods), labor costs, and agglomeration economies. The optimal location balances these cost components.

Question 2

What are isodapanes in Weber's theory?

Accepted Answer

Isodapanes are lines drawn on a map connecting points of equal additional transportation cost relative to the least-transport-cost location. They define the critical boundary within which labor cost savings can justify relocating away from the transport-optimal point. If wage savings exceed the isodapane cost, the industry moves toward cheaper labor.

Question 3

How does Weber's theory apply to India's steel industry?

Accepted Answer

India's integrated steel plants (Bhilai, Rourkela, Bokaro, Jamshedpur, Durgapur) locate in the Chotanagpur Plateau because steel production uses gross (weight-losing) materials — iron ore, coking coal, limestone — with a material index of ~4:1. Per Weber's theory, weight-losing industries minimize costs by locating near raw material sources, which is exactly what we observe.
