In Okazaki city, some blocks of city center were occupied by public offices. As these offices are the obstacle to the extension of shopping district with the city center, they have been removed to suburbs and their old sites have been redeveloped since 1970. This redevelopment is fairly large scale for a local city and the newly constructed center has multiple functions such as department stores, parking buildings, high-class speciality stores and hotels.<BR>In this paper, we consider the influence of redevelopment of the city center on the urban system in terms of the following three levels.<BR>(1) The influence on surrounding cities.<BR>Okazaki city is located in Nishimikawa region within Nagoya metropolitan area. The redevelopment of city center in Okazaki, therefore, have the influence not only on surrounding cities but also on Nagoya city. In analyzing the changing patterns of trade areas in Nishimikawa region before and after the period of the redevelopment, three types of areas can be recognized; (i) the areas in which the dependence-ratio on Okazaki increases and that on Nagoya decreases, (ii) the areas in which the dependence-ratios on both Okazaki and Nagoya increase, (iii) the areas in which the dependence-ratio on Okazaki decreases and those on surrounding cities or Nagoya increase. As the types of (i) and (ii) are observed in most of the areas, we come to the conclusion that the redevelopment of city center in Okazaki has led to enlarge and strengthen Okazaki trade area.<BR>(2) The influence on shopping streets in Okazaki city.<BR>Okazaki city are divided into four areas; central area in which the redevelopment has been proceeding, transitional area which is surrounding the central area in the buildup area of the city, fringe area I where population is growing, and fringe area II which is hilly region. By comparing the change of sales of shops within each area, before and after redevelopment period, we can recognize that the growth of sales in central area is over 150%. While there is little growth in the fringe areas and the decrease of growth rate in the transitional area.<BR>(3) The influence on the management of stores in the city.<BR>To sum up the conclusion of enquete method about its influence, the redevelopment lead to “the rise of pay to employees” and “the opportunity to the rationalization of store management” in central area. In transitional area, it resulted in “a diminution of customers and profits”, which means the largest damage among the three. The fringe area have little influence on the management.<BR>As mentioned above, the redevelopment of city center in Okazaki gave rise to various influence on the urban system. At the stage of the planning on redevelopment it may be necessary to investigate such influence beforehand.
