Sphere of influence

"The sphere of influence is the area surrounding a settlement that is affected by the settlement's activities." From http://www.bbc.co.uk

The sphere of influence of a shop is how far people will be prepared to go to make use of that shop. For example if people decide to travel a long distances for a shop that shop will have a big sphere of influence. But if a people didn't feel it was necessary to travel long distances to go there shop has a small sphere of influence.

The corner shops particularly has a small sphere of influence because as explained earlier in shopping hierarchy people travel by foot only talking a few minutes so meaning the person travelled a very short distance therefore a very small sphere of influence because it sells low order goods.

Department stores have quite a large sphere of influence of because department stores are in the CBD area and that is found in to city area which have many tourist's there. So if tourists come from long distance for example other countries it must have a large sphere of influence because it sells high order goods.
