Purchase Intention of e-Payment: The Substitute or Complementary Role of Brand, Sales Promotions, and Information Quality

What is it about?

e-payment is becoming more relevant in the era of the revolution industry 4.0 despite the corona health crisis. This study aims to determine the impact of brand equity, information quality, sales promotions, and the interaction effect between the three aforementioned antecedents to purchase intention of e-payment. The research used structural equation modeling, hierarchical moderated regression, and simple slope analysis to a sample of 241 respondents selected using proportionate sampling. Constructs were adapted from past studies, but only constructs passed the validity, reliability, and model fitness were subsequently used. This research affirms previous studies proving that information quality, brand equity, and sales promotions are positively associated with purchase intention. This study contributes to the literature when it finds the simultaneous significant positive effect of these three factors to purchase intention given the fact that past studies only tested separate effects. The study also confirms preceding discoveries that acquire a stronger effect once the interaction effect of overall determinants is considered. Yet, the interaction effect separately tends to substitute rather than a complementary role, although not significant. Therefore, theoretically, this study does not corroborate the new concepts of the isolated interaction effects. This study suggests new predictors and the various context in subsequent studies for the benefits of theories and practices.
