CONCLUSION AND IMPLICATIONS ............16 3 ABSTRACT In todays media landscape, the young generation, especially Genz prefer using social media channels (social networks) like Facebook, Instagram, Tiktok over traditional communication channels, such as television stations, newspapers to exchange information and build relationships (Hair, Clark and Shapiro, 2010). According to a survey the research team conducted, the impact of Influencer Marketing on GenZ in Ho Chi Minh City on the FnB industry has reached 65%. Several studies have also demonstrated how easily social media influencers can affect peoples eating decisions, especially young people and adolescents. This paper aims to analyse the factors of influencers that affect Gen Z consumers decision to purchase food and beverage products in Ho Chi Minh City. Then, apply and offer some recommendations for firms in the FB sector in Vietnam to increase the efficiency of brandpromotion efforts utilizing social media influencers. I. INTRODUCTION 1.1. The reason for choosing the topic Vietnam is making economic strides and has accomplished certain goals. As peoples living circumstances rise, eating well and wearing beautiful clothes has progressively replaced eating well and wearing warm clothes for quite a period of years. With a population of more than 97 million people, the majority of whom are young, this is a very promising market for the food and beverage (FnB) industry to quickly establish itself. FnB refers to the food and beverage sector. As a result, we may conclude that the FnB service industry is the business of food, beverage, and food goods, as well as the business of the dividends that comprise the brand. In the past few years, social media influencers have had a significant and overwhelming impact on the marketing of products, services, and corporate brands, especially in the FnB industry. Brands and their relationships with customers changed because of this major impact. Since every business, regardless of size, specialty, or category, finds 4 social media to be a valuable medium for reaching out to clients and potential customers with the least number of problems, the influence will not fade within the next year. 1.2. Overview of the research situation In todays world, traditional marketing channels become less important because of social media presence in more ways than one. While all traditional media and advertising options are expensive and usually out of reach for small businesses, social media has emerged as a potential lowcost and highly successful option for them. FnB businesses, which are now one of market leaders, may significantly reduce their advertising and marketing expenditures by utilizing social networking platforms. According to a Vietnam Briefing, accounting for 35% of monthly spending and 15% of the countrys GDP for the majority share of Vietnamese spending expenditure by FB accounts; this figure is likely to rise in the future years. After the Covid19 epidemic, the FB business had been rapidly expanding, owing to a confluence of favorable trends such as population expansion, rising household incomes, and changes in consumer behavior, especially Gen Z, through social media influencers. As shown by research examining Gen Z behavior, influencers have the capacity to impact their purchasing patterns. According to research by Kantar M.Brown (2020), 44% of GenZers have made a purchasing choice based on the suggestion of an influencer. In another Survey Monkey study, more than half of Gen Z (58%) have bought based on a suggestion from a social media influencer or content creator.

Influencer There appears to be a lack of concurrence about defining an influencer According to Keller & Berry (2003), an influencer is described as a person who has an active mind and creates activities that impact various networks To put it differently, an influencer is not required to be famous but whoever influences their own communities In the marketer world, the influencer of social media is defined in the definition of Duncan & Hayes (2008) that people mostly agree with: An influencer is a third party who has a considerable impact on a customer's purchase choice These influencers vary in different kinds and influence in different levels 2.1.2 Influencer marketing "Influencer marketing" is the practice of leveraging individuals with influence towards potential consumers, orienting marketing campaigns around these people to promote a business message and products to the global market via social networking platforms and partnerships with opinion leaders (Bijen, 2017; Levin, 2019) Thus, influencer marketing is remarkably effective This marketing form works in tandem with the creation of messages delivered by influencers to intensify brand awareness extent toward consumer segmentations in both cognition and emotion Although celebrities have always been used in marketing efforts to capitalize on their celebrity in order to promote enterprises (Cheah, Ting, Cham, & Memon, 2019), influencers on social media are a distinct and more modern use of this strategy Influencers and celebs are conceptually separate because influencers "natively" create their major activity on social media, whereas celebrities are known for their non-social media undertakings (Dhanesh & Duthler, 2019) (like sports, music, etc) 2021 (Tafesse and Wood) (Schouten et al., 2019) The reputation of influencers is thus solely based on the content they give and their social media involvement, which is often done in collaboration with their fans (Hu et al., 2020, Schouten et al., 2019) As a type of virtual friend, they typically target a more narrow audience with whom they have like interests Because they appear to be more in touch with their potential audiences, influencers frequently appear more trustworthy or reputable than traditional superstars (Lou & Yuan, 2019; Sokolova & Kefi, 2019) The fact that social media influencers become thought leaders or authority among their followers in their specialized domains reveals their importance and potential consequences (Rahman, Saleem, Akhtar, Ali, & Khan, 2014) As a result, when making purchasing decisions, followers commonly seek out or depend on their advise (Casaló et al., 2020; Schaefer, 2012) According to some past research (Choi and Rifon, 2012; Casaló et al., 2020), the resemblance between an influencer's appearance and followers' interests is a potential motivator De Veirman, Cauberghe, and Hudders (2017), Erz, Marder, and Osadchaya (2018), as well as other influencer studies have shown impacts related to their followers, hashtags usage, or activity metrics (Arora, Bansal, Kandpal, Aswani, & Dwivedi, 2019) Another area of research investigates the consequences of certain communication characteristics, such as how influencers expose the commercial origin of advice (Boerman, 2020, De Veirman and Hudders, 2020, Jin and Muqaddam, 2019, Sokolova and Kefi, 2019) Control the product-influencer fit and indicate that a great match leads to buyers having more positive feelings about the product and lowers their perceptions that the promo is advertisement (Kim and Kim, 2020) Instead of recommendations from the brand or company itself, customers are more likely to believe those from third sources This is especially true if you consider it in a personal context: it's difficult to trust someone you don't know at a coffee shop to start a conversation and then talk about themselves entice you to join their social network But if you and the person who shared those things were friends, you would be more likely to trust it Influencers, who connect companies with their target audience, are buddies with similar interests Influencers provide their followers resources for knowledge and creativity The best results for influencer marketing efforts are achieved when there is a high degree of congruence between the customer and the product This leads to greater positive sentiments of the item as well as improved purchase and referral intentions 2.1.3 Vietnam's F&B industry: The food service sector in Vietnam is expected to grow at an 8.50 percent CAGR between 2022 and 2027 A significant proportion of monthly earnings is spent on eating out, indicating that the sector is thriving The country now has 550,000 F&B outlets, including 430,000 conventional meals and 82,000 chain restaurants From 2022 to 2027, Vietnam's food service sector is predicted to grow at an 8.50 percent CAGR A third of monthly income goes on eating out, showing that the industry is rapidly expanding There are presently 550,000 food and beverage establishments in the country, including 82,000 fast-food restaurants and 430,000 typical restaurants Social influence comprises endorsements and promotion from celebrities, key opinion leaders (KOLs), and influencers as well as suggestions from their social network They can become devoted clients or occasional guests depending on whether they receive satisfactory services and rates that correspond to their impressions and the caliber of the meal The social networking sites that consumers use for social media influencers may be seen in the survey analysis's findings on the traits of consumers' practices of doing so in Vietnam The most popular social media platforms for following influencers are Facebook (93.5%), Instagram (87.1%), and YouTube (75.3%) The majority of consumers (94.6%) seek advice from influencers in the culinary industry who are qualified, skilled, and informed, such chefs, blogs, The majority of customers said they want to speak with influencers because they offer a lot of relevant information (63.5%), expertise and skills (56.8%), and there are lots of appealing product photographs (50%) All of the survey participants had considered and purchased the influential food items listed in the article 48.4% of participants sporadically view influencer postings, and 37.6% frequently so When consumers see social media influencers post about food and drink goods, they choose videos with 73.6% of the vote, followed by images with 66.7% 2.2 Conceptual model and hypothesis development Expertise Expertise level is defined as the extent to which the influencer is perceived as having knowledge or skill in a particular field (Ratchel et al., 2014) While expertise is highlighted to have a positive impact on both attitude and purchase intention (Till and Busler, 2000) Silvera and Austad (2004) highlighted that target groups' purchase intention is at a higher level when the influencers are more reliable since his/her higher expertise, trustworthiness and attractiveness When influencers post about particular products or promote brands on social media platforms using their own expertise, the message of the products or brands can be seen as more trustworthy to their followers rather than sponsored commercials (Kassoway, 2015) As a result, the following hypothesis is proposed: H1: The expertise of the influencer has a positive effect on consumers’ purchase intention Influencer Credibility Influencers are considered as more credible and trustworthy than typical celebrities, and this has a substantial influence on the purchase intentions of their followers Sen & Lerman (2007) back up Deatara et al (2019) findings by claiming that highly credible communicators are more convincing than those with poor credibility Jiang's (2018) study also stated that a credible celebrity has a favorable influence on marketing effectiveness, such as enhancing customers' perceptions toward the brand and purchase intention Based on this, it is proposed: H2: The influencer credibility has a positive effect on consumers’ purchase intention Likability Likability is described as the affection of an information receiver for the information source's appearance and character attributes (Kiecker & Cowles 2001; Teng et al., 2014) One of the most significant variables affecting a consumer's attitude is their opinion of an influencer (Li et al., 2014) In current study, likability is defined to be an individual’s tendency to be driven to the communicator’s charm or persona, or his/her level of sociability or approachability (Xiao et al., 2018) Therefore, likability of an influencer is positively shown to increase credibility, consumer attitudes and buying intention (Kumar, 2011) Thus, we extend our hypothesis as follow: 10 H3 = Likeability of the influencer has a positive effect on consumers' purchase intention Information Quality The quality of information is positively correlated with the reliability of authentication information (Cheung et al., 2012) The informative value of sponsored posts created by influencers positively influences consumers' trust towards those posts, and this ultimately shapes brand perception as well as consumer purchase intention (Arli, 2017; Taylor et al., 2011) Thus, the following hypothesis is projected: H4 = The quality of the influencers' information has a positive effect on consumers' purchase intention Entertainment Value Entertainment is crucial in forming customers' attitudes and affecting their buy intentions, according to previous research by Mustafi and Hosain (2020) Courtois et al., De Marez, and Verleye (2009) revealed that the major reasons for most consumers to load social media contents are enjoyment and escapism, which are the key indicators of entertainment fulfillment Organizations may enhance their value from consumers by successfully entertaining them and increasing their perspectives of brands through word-of-mouth and brand trust (Kang, 2005) As a result, an influencer's content having such perceived entertainment value is also likely to shape credibility and purchase intention Consequently, hypothesis is thus proposed: H5 = The influencer’s entertainment value has a positive effect on consumers' purchase intention Figure 1: Proposed research model 11 III METHODOLOGY 3.1 Measures This article uses the quantitative research method by comparing statistics from reputable sites and referencing related documents The questionnaire is

firmly anchored in how consumers change their behaviors to stay current with the latest trends Thus, this paper contributes to the model that investigates the influence on influencer marketing on social media on purchase intention of consumers toward food and beverages products in HCM City with five components, namely Expertise, Influencer credibility, Likability, Information quality, Entertainment value Based on research regarding how influencer marketing affects customer purchasing behavior, the authors stress the significant importance of all three factors of influencer's expertise, influencer's likability, influencer's entertainment value all have a positive impact on the intention to purchase food and beverage products at different levels of impact In which, the influencer's likeability has the strongest impact on the purchase intention, while the expertise factor affects the purchase intention Finally, the factors in the model have explained the variation of intention to purchase food and beverage products This study was conducted for FnB businesses when using influencers to promote their products, so it is important for businesses to understand these influencing factors In addition, this study also helps influencers on social networks to capture customer behavior so that they can learn from experience and create greater influence According to research results, businesses, communications, and marketers should recognize the influences and consequences of influencers on customer purchasing 16 decisions in order to develop marketing strategies that suit consumer behavior and effectively use influencer marketing Businesses identify influencers within the FnB industry and focus on individuals with common audiences Via their Personal Brand (life idea, fashion style, statement), demographic data (gender, age, marital status, field of activity), and content of postings on personal sites, companies can assess how relevant an influencer is to their brand Besides, businesses in the food and beverage field can select influencers with knowledge and skills in the culinary sector, such as chefs, culinary experts, food stylists, and food reviewers to strengthen the persuasiveness of their marketing campaigns Businesses should give influencers precise information and understanding about the product while dealing with them so that they can understand it and convey it to readers When selecting an influential face to represent their brand, businesses should consider this influencer reputation, especially regarding controversies, and negative information Moreover, if this influencer is advertising many brands at once, he may promote brands with contrasting images, which will cause negative reactions in consumers Customers will become irritated and believe that the influencer only writes about products because they are paid, which will damage their faith in the influencer Businesses also need to know whether the influencer can maintain the quality of their posts Customers will readily trust these influencers if the quality of their content is consistent, created with care, and enthusiastically shared Simple posts, influencer personal shares, and sponsored pieces ought to be distributed fairly Consumers would conclude that an influencer has only one goal to generate money if all of their articles are advertisements for brands rather than just offering information that will benefit the industry Taking advantage of these applications, developing influencer marketing will help reduce more commercial costs than traditional marketing activities, hence maximize company’s profits The study limitations include we excluded conference papers and theses due to quality concerns that could not be assured and only chose peer-reviewed journal articles and books As a consequence, it is not possible to generalize the relationships discovered in the research to all types of opinion leaders or social media platforms The second is that the sample size is not large and the objects of observation are concentrated in Ho Chi 17 Minh City Therefore, subsequent studies can be extended to the sample size and research space to improve the generalizability of the research model Therefore, one of the next research directions that the team wants to improve is to be able to go into the field to accurately record and find out if there is a difference in the questionnaires answered directly by the respondents consumers per region compared to an online survey 18 Reference Arli, D (2017) Does Social Media
