The standard rule of thumb in the business being one department store for every 200,000 people, Taipei, with a population of 3 million, should be able to support only two thirds of them. Driven by the fierce competition, department stores have generally turned to Japanese firms for technical or financial help in moving upmarket.
一般以廿萬人口設立一家百貨公司來估計，台北市三百萬人口數，只夠支持三分之二的百貨公司生存。在面臨過飽和的激烈競爭下，與日商技術或合資合作，便成了國內百貨業突破經營瓶頸的不二法門。
