Urban areas are composed of various urban functions, the structure of which shapes spatial influences of the area. The structure of urban functions can be viewed in three different ways; Quantitative, dimensional, qualitative aspects. Lots of researches have been made into spatial influence of the central areas in the cities, but most of them were focused mainly on the quantitative and dimensional features of central areas, not on the qualitative features being increasingly significant in the present cities. To present a basis to quality-oriented approaches, this paper focuses on establishing an index to measure how much qualified an urban function is. We investigated on the basic concept of qualitative difference shown in Berry's theories, and as a result of this, 'Functional Quality Index' was proposed to measure spatial influence of each urban function. Based on the responsiveness of increasing trend of functions as the market size became large, this index was considered to be appropriate in measuring qualitative difference between urban functions and was applied to major 90 major urban functions in Korean cities. The result was also used in some investigations on the functional characteristics and structure of major centers of Seoul, thus we could find some usefulness of this index in related studies and researches.
