The purpose of this study was to verify the effect of mobile fashion shopping characteristics and perceived interactivity on perceived usefulness, and the effect of perceived usefulness on purchase attitude and purchase intention based on TAM (Technology Acceptance Model). We conducted the survey targeting smartphone users in their 20s~30s living in Seoul and metropolitan area. Among 483 data collected, we used 452 samples except 31 unreliable respondents for the analysis. To analyze the structural equation model, we did factor analysis, reliability analysis, and structural equation model analysis using SPSS 18.0 and AMOS 16.0. The results were as follows: We confirmed 5 mobile fashion shopping characteristics (enjoyment, credibility, instant connectivity, security, and personalization) and 3 perceived interactivity factors (control, responsiveness and two-way communication, and contextual offer) as results of confirmative factor analysis. Mobile fashion shopping characteristics and perceived interactivity had positive effects on perceived usefulness. Mobile fashion shopping characteristics affected perceived interactivity and also had indirect effect on perceived usefulness via perceived interactivity. In other words, mobile fashion shopping characteristics had direct and indirect effect on perceived usefulness. Perceived usefulness influenced purchase attitude and purchase attitude influenced purchase intention. Perceived usefulness had direct effect on purchase intention and the indirect effect through purchase attitude was significant.

In this study, we identified the factors of perceived interactivity and verified the path model of effects of these factors on mobile fashion shopping purchase intention through perceived usefulness and perceived ease of use. To develop the conceptual model, we consulted the related precedent studies and searched various kinds of literatures. To verify the conceptual model, we conducted the survey targeting smartphone users in their 20s~30s and analyzed the structural equation model using AMOS 16.0. The results were as follows. Control, responsiveness and two-way communication, and contextual offer were identified as the factors of perceived interactivity. Perceived interactivity and perceived ease of use had positive effect on perceived usefulness. Perceived usefulness affected attitude toward purchase, and attitude toward purchase influenced positively on purchase intention. Perceived usefulness affected purchase intention directly as well as indirectly through attitude toward purchase. Based on the results, we proposed the marketing strategies for mobile fashion shopping businesses.
