Determinants affecting online shopping consumers’ satisfaction and repurchase intention: Evidence from Vietnam

In the digital age and technological advancements, short video platforms have become essential tools for online sales and marketing. In addition, shopping through short video marketing has gained significant attention, especially among Generation Z, as it brings unique and novel shopping experiences. The primary goal of this study is to explore the factors of short video marketing that influence the purchase intentions of Generation Z consumers in Vietnam. To conduct this study, a quantitative approach was employed, utilizing a 5-point Likert scale questionnaire administered online through a non-probability sampling method. The sample comprised 350 respondents aged between 16 and 26 from Vietnam, representing Generation Z, who made purchases through short video marketing. The relationships among various variables were analyzed using Structural Equation Modeling (SEM). The study’s results demonstrated a positive, significant, and direct relationship between all factors of short video marketing, including interesting content, perceived usefulness, scenario-based experience, user interaction, perceived enjoyment, and involvement of celebrities and consumer brand attitude. Among these factors, perceived usefulness is the most influential factor on customer brand attitude. In addition, the study revealed that consumer brand attitude, acting as a mediating variable, had a positive and significant impact on consumers’ purchase intentions. Based on the findings, the study suggested strategies for businesses to enhance the quality and content on short video platforms, thereby improving the effectiveness of their marketing strategies.

Flash sale (FS) is a marketing strategy that is widely used and developed in sales through e-commerce. The implementation of the FS strategy is to provide discounts or special propositions on products offered within a certain time limit. Time restrictions aim to encourage consumers’ emotions to make impulse buying (IB). This study examines the effect of consumer emotions as a mediating variable on IB among Shoppee consumers in Indonesia caused by FS activities that are not carried out on certain important days. The required data were collected through the distribution of online questionnaires to respondents who, in the last three months, had made transactions through Shoppee e-commerce platform. A total of 150 questionnaires are analyzed using PLS-SEM. The results of the analysis show that the flash sale strategy carried out by the Shoppee e-commerce platform in Indonesia has a direct effect on increasing consumer emotions. This means that the higher the intensity of the FS promotion, the stronger the influence on consumer emotions. Emotions increase IB. FS has no significant effect on increasing IB. Subsequent findings show that FS indirectly has a positive and significant effect on IB through emotions. In other words, this study proves that the emotions are a mediating variable in online IB. This study is helpful for companies in developing appropriate strategies for their promotions in utilizing consumers’ impulse buying behavior by using strategies that trigger consumers’ emotions.

This article investigates the effect of firm size on the performance of Vietnamese private enterprises. Based on the data from the Annual Enterprise Survey from 2009 to 2018, this study uses an ordinary least-squares regression model (OLS) to point out the effects of firm size (growth rate, total assets, and total labor) on the performance of Vietnamese private enterprises in both static and dynamic states. According to the results of the quantitative model, total assets are the biggest factor for determining firm performance, followed by total labor and growth rate. The results highlight the issue in Vietnamese private enterprises development in terms of scale, despite the fact that their number is growing, as the scale of enterprises decreases (the proportion of micro and small enterprises increases, but the proportion of medium and big enterprises decreases). Besides, the disadvantages of scale also negatively affect the development process of Vietnamese private enterprises, including accessing capital, increase in production or productivity, business expansion, and improving competitiveness.
