Therefore lower level stores have more expensive rental fees, and the stores, which are located on the first floor, are influenced by accessibility more than other businesses. Also, they are willing to pay more rental fees relatively. However, the stores, those are located on upper level in the building, have less influenced by accessibility. The second, ratio of area for exclusive use is increased by upper level than lower level in the commercial buildings. It looks like the owner would like to make more tenant on the lower floor due to high rental fee, also there are more demand on the lower level than upper level stores. Thus, the study find out that the businesses located on lower level are not to demand large space, and the upper level stores are figured out the opposite phenomenon. The third, the floor is decided by the business' features. Each business has different importances for its business such as main factor, requirement of space to run business, and solvency of rent. It looks like these elements effects on decision of floor, and it shows the difference of distribution in the commercial buildings. 2.
