The purpose of this study is to analyze architectural designers' aesthetic valuation for alternative selection of Sewoon shopping complex at Seoul through binary logistic regression analysis based on aesthetic value and attractiveness value. The results of this study showed that: first, we defined the value of architectural aesthetic as attractiveness value; second, psychological value and political value had an influence on architectural designers' aesthetic valuation. Social value had a relatively less influence on architectural designers' aesthetic valuation but did not meet the significance level; third, variables in Model Ⅱ(M2) had an influence on architectural designers' aesthetic valuation. Each Exp(β) value of them is 1.393(bequest value), 1.332(inherent value), 1.281(option value), and 0.669(quasi-option value) at the significance level of 0.05 (P<0.05); fourth, each Exp(β) value of aesthetic value as a factor of alternative selection is 1.577(bequest value), 1.313(use value-attraction value), and 1.264(use value-shopping) at the significance level of 0.05 (P<0.05).
