• There are different types of land
use such as
• Commercial land use
• Residential land use
• Industrial land use
• Institutional land use
• Transportation land use

together because of
• Similar locational requirements and
• External economies of scale
• different types activities are
separated from each other because
• Different locational requirements
• Different rent-paying ability
• Conflicts amongst them
Bid Rent Mechanism
• Land rent decreases with increasing
distance from city centre
• competition for land and accessibility
push up the land value/rent
• different land use has different rent
curve
• because they have different demand
for accessibility and space
Commercial land use
• needs large number of people to
support their business
• Greater market threshold
• highest demand for accessibility
• require less space
• Can afford higher rent
Residential land use
• Accessibility is not important
• require more space (especially high
class residential area)
• cannot afford high rent
Industrial land use
• Accessibility is not very important
– require large area of space
• cannot afford high unit rent
• There is great difference between
light and heavy industry
