Knowing why consumers choose their favorite products can help enterprises to stay ahead of market trends and thereby increase profits and reduce losses. There are various theories which attempt to explain what happens in the minds of consumers when they purchase a product. However, methods of applying these theories to an enterprise are needed but are rarely discussed in the literature even though having a practical method of understanding consumer thinking would help enterprises understand those proposed theories easily. In this study, we propose a Product Common Attribute (PCA) model and provide quantified values to help enterprises to apply consumption value theory to their products. Because it is difficult to quantify each value index of a consumption value theory, the PCA model is proposed to correspond to the five value indices of consumption value theory, incorporating a questionnaire survey to verify the corresponding relationships. Consequently, this study quantifies and applies the relationship between the PCA model and consumption value theory.
