　　The distribution and intensity of residential, employment, and recreation- shopping activities in Taipei metropolis has been influenced by the MRT system, which has opened in succession since 1996. To understand the development changes of corridor before and after the MRT opening is helpful to make development strategies in the MRT station areas. The traditional statistics methods which depend on crisp and subjective concepts, were usually used to study spatial structure in metropolis. Since the recognition of activity cores is hard to define, it would be more suitable to be analyzed by the methods, which can objectively deal with uncertainty. The case study on the MRT stations of blue line was concluded as follows: (1) the number of residential activity cores decreased while employment and recreation-shopping activity cores both increased; (2) the function of residential activity cores was becoming insignificant while the function of employment and recreation-shopping activity cores was becoming significant after MRT opening; (3) the residential activity cores backed away from the CBD while the employment activity cores expanded outward, and two major recreation-shopping activity cores were formed in the east and west area respectively after the MRT opening. The strategic sensitivity analysis on Panchiao Station was analyzed by increasing industry and business floor area under four scenarios. It was found that whether Panchiao Station area might develop into an employment activity core or should be an employment activity core depends on the extent of its floor area increase, i.e., either 175 ~ 500% or 250 ~ 700%.
