This study focused on the effects of aesthetic taste, product purchase motivation (functional, hedonic), product attributes (design, function, pleasure, price, discount) and self-affirmation on purchase intention. By means of the application of Questionnaire Method, and based on the collected random samples aimed at the students in the colleges or universities in Southern Taiwan, 960 copies of questionnaires had been issued. The results showed that when consumers purchase products, aesthetic taste would influence their consideration of product attributes and then generate purchase intention. Consumer's self-affirmation was observed to have significant effects on his or her purchase decision. But product purchase motivation is irrelevant to choice of a highly aesthetic product.
