ABSTRACT
E-commerce is creating growth opportunities for e-retailers, especially during the Covid-19 outbreak. It increases the perceptions of both providers and customers toward their shopping convenience. In 2021, Vietnam became one of the fastest-growing countries among Southeast Asia's Internet economies. However, both scholars and management practitioners have argued the inconsistent assessments of the factors affecting customer purchase behavior in online settings. Thus, this study aims to identify the critical factors influencing customer behavioral intention toward e-commerce websites that were adopted from well-established models and relevant literature. The online survey was the data collection method. All items were measured through a 5-point Likert scale. This study proposed and analyzed a conceptual framework using existing survey data from 312 samples in the context of online buying via e-commerce websites. Data were analyzed by using the statistical tool SPSS. The results indicated that factors including perceived usefulness, transaction security, perceived ease of use, trust, and subjective norm positively influence customer shopping intention. The results revealed the most prominent impact of the transaction security on customer purchase intention. Besides, perceived risk is a significant barrier in online shopping through e-commerce websites. The researchers have brought practical insights and made conceptual contributions by extending existing research on the technology acceptance model (TAM) and theory of planned behavior (TPB) regarding online shopping on the e-commerce website. The paper helps to validate and strengthen the importance of customer purchase intention in an e-shopping environment. The findings would help e-commerce providers be able to formulate specific strategies to increase customer usage significantly. Moreover, managers can focus their attention and resources on the greatest significant factors regarding their effects on behavioral intention.
