The purpose of this paper is to investigate the spatial distribution, location characteristics of Taipei's USC's. Besides, in order to find out the characteristics and behavior of consumers in this special space, we observe the three USC's which have run over one year, collect questionnaires filled out by consumers. The results of this research can be summarized as follows: the spatial distributions of Taipei's USC's share four characteristics. First of all, they have close relation to the urban development plan. Next, the location of the highest USC density is situated in Zhong Zheng District (中正區), which is also the CBD of Taipei. Third, the proportion of the USC's "associated with MRTS" is higher than that of the USC'S "dissociated from MARTS." Forth, most of them are in the shape of ribbon development. When the managerial scale, traffic gathering and commercial environment are taken into consideration, the locations of Taipei's USC's fall into three categories: the main urban center, the secondary urban center and the community center. Basically, the location of a USC is closely related to its scale. However, the schemes of the completed USC's in Taipei didn't follow this principle. In addition, according to the USC consumer survey, we found: the mechandise had better to be youthful, fashionable and more suitable for women; the mechandise price shouldn't be too high; and there should be more stores for restaurants and teashops. That is what most of the consumer's want. But the supply of the USC's in Taipei at present isn't able to meet the demand. Therefore the rising consumptive space neither operates by its rule nor impacts the existent commercial space.
