Mapping the literature on Gen Z purchasing behavior: A bibliometric analysis using VOSviewer

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.

Halal food production is a crucial sector for Muslims, especially Generation Z, who spend time eating in stalls and restaurants instead of eating homemade food. This tendency is higher than in the previous generation. Thus, this study aims to estimate the factors influencing the purchase intention of halal food for Generation Z Muslims in Indonesia. This quantitative study uses a questionnaire distributed randomly online to 352 respondents. Data analysis and hypotheses were examined using the structural equation model (SEM) approach. The results show that religious belief, exposure, and health reasons are essential in increasing halal awareness. Meanwhile, halal awareness and knowledge positively contributed to increasing interest in buying halal food. On the other hand, Islamic brands do not affect the buying interest of Generation Z Muslims in halal products. This shows that Islamic brands in the food sector have no impact on Generation Z Muslims in a Muslim-majority country like Indonesia. This also confirms previous studies conducted in Muslim-majority countries such as Saudi Arabia that Islamic brands do not increase interest in buying halal food. This is because they are used to buying food without seeing the Islamic brand as long as it is halal. However, this result may be different if Muslims live in a non-Islamic country since Islamic branding can provide a comfortable feeling for Muslims in a non-Islamic country.

Integrated marketing communication (IMC) is an effective marketing practice in the age of social media. IMC builds customer relationships and enhances brand value by integrating information from multiple channels and strengthening user interaction. The purpose of this study is to present the development process, current hotspots, and future trends of IMC research. Moreover, it explores the characteristics and patterns of IMC research. First, this paper shows the annual literature volume, leading countries, journals, and authors in IMC research through bibliometrics. Then, five hot research topics are identified through keyword co-occurrence analysis, namely IMC theory and models, brand communication, media research, customer research, and marketing strategy. From 1991 to 2020, IMC research is divided into five phases, each of which is related to the enhancement of user interaction. Future IMC research will continue to be user-centered, and IMC research will continue with social media and branding, as well as research on other topics that can further enhance user interactions. This paper also finds that the characteristics of the concept of IMC itself lead to a constant renewal of its connotations, which is one of the reasons why scholars cannot reach a consensus on the concept of IMC.
