This study examines the factors affecting millennials and generation Z’s purchase intention in online shopping. The variables under investigation, namely, impulse purchase orientation, quality orientation, brand orientation, online trust, and online purchase experience, were tested. The data collection approach used a web-based questionnaire that was created and distributed to 584 university students in Malaysia. Data were analyzed via the Partial Least Squares-Structural Equation Modeling (PLS-SEM) approach to examine the posited research hypotheses. The results revealed that impulse purchase orientation was the strongest predictor of consumers’ online purchase intention in Malaysia. This is followed by online trust, and the online purchase experience and quality orientation. Meanwhile, brand orientation did not affect customers’ intention to purchase online. The results contribute new and extensive inputs into the marketing theory and expand the emergent literature on consumer intention to shop online in Malaysia, whereby rich multi-ethnic cultures should be fully exploited. Future directions are offered.

This study examines the factors influencing customers' online purchasing intentions. A questionnaire was administered to a group of 584 respondents through the purposive sampling method. Data were analyzed via the Partial Least Squares-Structural Equation Modeling (PLS-SEM) approach to examine the posited research hypotheses. The PLS-SEM approach revealed that impulse purchase orientation was the strongest predictor of customers' online purchase intention in Malaysia. This was followed by an online purchase experience, and then online trust and quality orientation. It is also discovered that brand orientation does not significantly influence customers' online purchase intention in Malaysia. This research is helpful to online retailers in the development of business strategies and also the academicians to conduct further research by adding a new variable in the mix for generation and evolution of the concept. The originality of the paper is its investigation of the determinants as the predictors in the proposed theoretical framework and the Decomposed Theory of Planned Behavior (DTPB) as the underpinning theory for this study, something that has been overlooked in prior studies. The results underpin new and extensive inputs into marketing theory and enlarge the emergent literature related to customers' purchase intention in online shopping in Malaysia. Directions for future research are offered.
