A Study on Purchase Behavior of Bio Cosmetics Applying the Theory of Planned Behavior(TPB): Mediating Effect of Brand Image

Abstract

The purpose of this study is to examine the TPB(Theory of Planned Behavior) factors that affect the purchasing behavior of bio cosmetics consumers and to examine the mediating effect of brand image in the relationship between them. In this survey, cosmetics consumers aged 20 or older residing nationwide were selected as the population. Bio-cosmetics consumers in their 20s or older living in the Seoul metropolitan area were selected as a sample group, and an online survey was conducted for about 4 weeks in October 2022. For statistical processing of the collected data, multi-regression analysis and bootstrapping were performed using SPSS 28.0 and SPSS Macro 3.4 to verify the hypothesis. As a result of the study, Attitude, Subjective Norm, and Perceived Behavioral Control had a significant effect on purchase behavior, and the mediating effect of brand image was confirmed. Therefore, in order to increase consumers' purchasing behavior, it seems to be very important in terms of marketing to build an image such as awareness and trust in the brand as well as the functional efficacy of bio-cosmetics. These research results will have great implications for the bio-cosmetics industry preparing for the post-corona era.
