Introduction Driven by the rapidly evolving media landscape, firms extensively use social media to engage with their customers (Avery et al., 2010). Today, social media is an integral part of an individual’s daily life, which makes a vital venue through which companies connect with customers (Men & Tsai, 2011; Utz, 2009). Given the increased use of social media, recent studies have investigated how social media cultivates customer relationships with celebrities and/or media personalities (e.g., Smith, 2010). In light of the effectiveness of social media as a marketing tool, it is noteworthy to analyze the source power of celebrities and social relationships and consider how to take advantage of the power. The parasocial relationship is founded upon the communication process, which is an important factor in understanding the relationship between media and users. Parasocial relationships differ according to the motives for using social network service (SNS), while connection and attachment to celebrities, such as having empathy for a particular celebrity, is affected by celebrity source credibility. (Ohanian, 1990). The purpose of this study is to clarify the relation between parasocial relationships and customer equity in the social media context. The study investigates effects of motivations to use SNS and source credibility on parasocial relationships, as well as the effects of parasocial relationships on attitude and customer equity, and customer lifetime value. Theoretical Frameworks In this study, parasocial relationship refers to a virtual intimacy between a media personality and the media users, in other words, it is a psychological, interpersonal relationship unilaterally formed by users based on proximity, similarity, and attraction to the media personalities (Rubin & Step, 2000). When a parasocial relationship is formed, the media consumer appreciates the values and motives of the media character, often viewing him or her as a counselor, comforter, and model (Horton & Wohl, 1956). When using an SNS, users’ communication habits and their selection of social network services vary according to their motives, which in turn affect the parasocial relationships with celebrities via SNS. Motives for using SNS, specifically, information seeking, entertainment, and social connection may have a positive relationship with parasocial relationships. Source credibility, the positive characteristics of a communicator that affect the receiver’s acceptance of a message, positively influences parasocial relationships (Ohanian, 1990; McCracken, 1989) based on expertise, trustworthiness, and attractiveness of the media celebrities. In the social media context, a parasocial relationship has positive influence on attitude toward using an SNS. Social media users engage in finding people with whom they have an offline connection (Ellison, Steinfield, & Lampe, 2007). Social media enables individuals to connect with others all around the world easily, it is not surprising that parasocial relationships influence users’ attitude toward using social media, offering environments to enhance connections (Byod & Ellison, 2008). Further, it is worthwhile to note that parasocial relationships may have a positive influence on customer equity. The key to customer equity lies in understanding the customer lifetime value concept, which refers to the net present value of a customer’s profit stream (Rust, Lemon, & Zeithaml, 2004). Parasocial relationships positively influence brand, value and relationship equity, with the emergence of brands as one of the key organizational assets (Gummesson, 2004). Parasocial relationships explain relationships between individuals and brands, product, symbols, objects, and corporate identities. Such relationships allow individuals to have bonds with brands, trademarks and other symbols, politicians, sportsmen or even actors (Gummesson, 2004). Thus, they positively influence customer equity including brand equity, value equity, and relationship equity. Focused on effects of motivations to use SNS and source credibility on parasocial relationship as well as the effects of parasocial relationship on attitude, customer equity, and customer lifetime value, this study tests the following hypotheses: H1: Motivations to use SNS will have a positive influence on parasocial relationship. H2: Source credibility will have a positive influence on parasocial relationship. H3: Parasocial relationship will have a positive influence on attitude toward using SNS. H4: Attitude toward using SNS will have a positive influence on customer equity. H5: Parasocial relationship will have a positive influence on customer equity. Methods This study used a survey to investigate key questions about the associations between parasocial relationships and customer equity. A total of 350 social media users recruited from Hong Kong and Macau in China participated in the survey. Of the 350 participants, 129 were men (36.9%) and 221 were women (63.1%), with ages ranging from 21 and 35 years old (mean = 25.6 years). This study measured motivations for using SNS on a five-point Likert scale (1 = strongly disagree; 7 = strongly agree), which was adapted from an existing motivation scale (Leung, 2009; Leung & Wei, 1998; Sheldon 2008). To measure source credibility, this study used a five-point Likert scale, which was also adapted from an existing source credibility scale (Eisend & Langner, 2010; Priester & Petty 2003). Parasocial relationships were measured on the basis of user responses to 17 items on an existing five-point scale that assessed parasocial relationships (Koeppel et al., 1993). This study measured attitude toward using SNS through an existing scale (Venkatesh, Morris, Davis, & Davis, 2003). Customer equity was measured using an existing five-point scale (Keller, 2003; Rust et al., 2004) that elicited user responses to 13 items. Customer lifetime value (CLV) was calculated only for the customers in the sample, and CLVs were calculated separately before the average was taken by using the equation below: The CLVij of customer i to brand j, is given as: Tij= Frequency of purchases by customer i for a specific period of time dj= The rate of discount offered by company j fi= Annual average frequency of purchases by customer i for a certain period of time Vijt= The amount of purchase of brand j by customer i for a period of time t πijt= Expected profits by purchase unit of brand j by customer i for a period of time t Bijt= Probability that customer i buys brand j in purchase t Results The overall goodness-of-fit for this measurement model was acceptable (Chi-square = 8.218, df = 5, p = 0.145, GFI = 0.992, CFI = 0.991, RMR = 0.095, RMSEA = 0.043). The reliability coefficients of all 20 motivation measures were 0.885, and they were based on three factors of information seeking, entertainment, and building relationships. The reliability coefficients of all 16 source credibility measures were 0.924 with three factors of attractiveness, expertise, and trustworthiness. The reliability coefficients of all 17 parasocial relationship measures were 0.866 with three factors: proximity, similarity, and attachments. The reliability coefficients of all 13 customer equity measures were 0.838 with three factors of value equity, brand equity, and relationship equity. Cronbach’s alpha for attitude was 0.792. The coefficients indicate the acceptable reliability of the measures. Motivations to use SNS showed statistically positive effects on parasocial relationship (β = 0.151, p < 0.001). Specifically, entertainment (β = 0.148, p < 0.01) and building relationships (β = 0.093, p < 0.05) motivations showed significant positive effects on parasocial relationships while information seeking motivation did not show significant effects on parasocial relationships (β = 0.074). Source credibility showed statistically positive effects on parasocial relationship (β = 0.316, p < 0.001). Thus, the results supported H1 and H2. Parasocial relationships showed statistically positive effects on attitude (β = 0.295, p < 0.001) and customer equity (β = 0.272, p < 0.001). Attitude showed statistically positive effects on customer equity (β = 0.172, p < 0.001). Thus, the results supported H3 and H4. Customer equity showed statistically positive effects on customer lifetime value (β = 3.452, p < 0.001). Thus, the results supported H5 (see Table 1, Figure 1). Discussion This study contributes to clarifying parasocial relationships in the social media context and determining the relationships between parasocial relationship and customer equity. This study contributes to the theoretical foundation and implications of parasocial relationships and customer equity. Specifically, motivations to use SNS and source credibility positively influence parasocial relationship. Parasocial relationships have positive effects on attitude and customer equity. Customer equity, in turn, has positive effects on customer lifetime value. The study is the first of its kind on the effects of parasocial relationships on customer equity in the social media context. The study finds that motivations and source credibility are important antecedents of consumers’ parasocial relationships formed via social media. Parasocial relationships have a positive effect on attitude and customer equity, and customer equity leads to increased customer lifetime value. This study suggests that parasocial relationship is one of the strong influential variables on customer equity as it improves customer lifetime value. Thus, marketers should definitely consider parasocial relationship management in the social media context while tailoring their brand communications to their most profitable customers and enhance their customer lifetime value.

Driven by the consumer demand for companies to be socially responsible, companies are increasingly relating their brands to causes and charities in order to accomplish nonprofit objectives and corporate sustainability. In a social marketing campaign, the consumers’ choice of the cause can influence their reactions through the processes of choice. Allowing the consumers to choose the cause may also reinforce their personal role in the donation process, which may result in a better outcome. Further, advertisers are paying increasing attention to the launch of social marketing campaigns via social media, since social media has recently become an essential part of daily life and therefore an imperative venue through which companies connect with consumers. Focusing on the rapidly evolving social media landscape, this study primarily clarifies (1) how choice influences consumers’ perceived interactivity with a social marketing campaign in the social media context, and (2) consumer involvement, as consumers’ individual differences can enhance or limit the effects of a social marketing campaign with choice. Using field experiments, this study investigates the relationships between the consumers’ choice, perceived interactivity, attitude, and purchase intention, and considers the moderating effects of involvement on those relationships. This study’s contributions are that it illuminates (1) the effects of choice on the perceived interactivity of social marketing campaigns in social media contexts, (2) the role of involvement in social marketing campaigns as a moderator, and (3) attitude and purchase intention as outcomes that can facilitate the construction of a theoretical model for social marketing campaigns with choice in the social media context and offer possible implications for advertising practitioners.

The empirical study at hand explores the relationship between traditional and social media, and shows that media coverage and different forms of corporate communications do have an impact on social media chatter. Moreover online advertising is capable of taking advantage of awareness aroused by media coverage.

The main purpose of this study is to introduce and examine a multidimensional model of almost all relevant social media characteristics and their impact on brand perception and brand behavior. In order to incorporate social media’s high complexity we introduce our concept of SMURF and its related outcomes. Therefore we follow the original idea of Muniz and O’Guinn (2001) that define a brand community as a customer-customer-brand triad. Furthermore, we suggest an extension of their model that includes four dimensions covering all SMURF of a social media brand presence (SMBP), namely (1) customer-brand relation, (2) customer-customer relation, (3) customer-community relation and (4) customer-channel relation. For our defined core constituents of brand perception as well as for the essential elements of brand behavior already existing and tested reflective measures were used. Regarding the multidimensional construct of SMURF, the measurement instrument by Wiedmann, et al. (2013) was used. In detail, any SMURF core element was captured with one global item. Furthermore, any reflective and formative measures were specified to those brand and Facebook fan page which has been tracked most frequently by the respondent. The first contribution is to provide a multidimensional framework of value-based drivers of SMURF with special focus on an overall brand presence context. Second, the findings contribute to explain the consequences of social media attractiveness such as unique relevance features which provide a great brand appeal. In this study, customers who are strongly attracted to a brand fan page experience a high positive brand perception as well as a high positive brand behavior. Third, the empirical findings of the applied PLS-SEM approach indicate that customers have a specific motivation of being attracted and connected to a brand in a social media context.

This paper focuses on the social implication of new media art, which has evolved with the advance of technology. To understand the notion of human- computer interactivity in media art, it examines the meaning of “cybernetics” theory invented by Norbert Wiener just after WWII, who provided “control and communication” as central components of his theory of messages. It goes on to investigate the application of cybernetics theory onto art since the 1960s, to which Roy Ascott made a significant contribution by developing telematic art, utilizing the network of telecommunication. This paper underlines the significance of the relationship between human and machine, art and technology in transforming the work of art as a site of communication and experience. The interactivity in new media art transforms the viewer into the user of the work, who is now provided free will to make decisions on his or her action with the work. The artist is no longer a god-like figure who determines the meaning of the work, yet becomes another user of his or her own work, with which to interact. This paper believes that the interaction between man and machine, art and technology can lead to various ways of interaction between humans, thereby restoring a sense of community while liberating humans from conventional limitations on their creativity. This paper considers the development of new media art more than a mere invention of new aesthetic styles employing advanced technology. Rather, new media art provides a critical shift in subverting the modernist autonomy that advocates the medium specificity. New media art envisions a new art, which would embrace impurity into art, allowing the coexistence of autonomy and heteronomy, embracing a technological other, thereby expanding human relations. By enabling the birth of the user in experiencing the work, interactive new media art produces an open arena, in which the user can create the work while communicating with the work and other users. The user now has freedom to visit the work, to take a journey on his or her own, and to make decisions on what to choose and what to do with the work. This paper contends that there is a significant parallel between new media artists’ interest in creating new experiences of the art and Jacques Rancière’s concept of the aesthetic regime of art. In his argument for eliminating hierarchy in art and for embracing impurity, Rancière provides a vision for art, which is related to life and ultimately reshapes life. Rancière’s critique of both formalist modernism and Jean-François Lyotard’s postmodern view underlines the social implication of new media art practices, which seek to form “the common of a community.”

동시대 사회적 변혁에 있어서 디지털 미디어의 역할에 대한 도구적 관점은 정치 적으로 조망되고 있다. 방송미디어의 가치는 평가 절상되었고 시민들이 사적으로 소통하는 미디어는 가치 평가 절하되었다. 그러나 중동사태, 영국폭동, 일본 쓰나미 와 후쿠시마 원전 폭발사전, 한국에서의 시장선거(2011)에서처럼, 소셜미디어는 기 득권 미디어의 대안으로서의 역할을 분명히 하고 있으며 의제설정의 힘을 획득하 고 있다. 본 연구는 소셜 미디어가 사람들로 하여금 인식을 공유케 하는 역할을 점 검하고 보수적인 권력이 소셜 미디어와 네트워킹 현상에 대해 대처하는 방식을 검 토하고 있다. 또한 본 연구는 소셜 미디어가 사회적 합리성을 증진시키는 도구로서 의 역할을 수행함에도 불구하고 소수의 엘리트에 의해 과점적으로 지배되어 권력 의 면역시스템 기능을 수행할 수 있다는 점에 우려를 표명하고 있다.

본 연구는 대학생들의 일상생활에서의 사회 및 정치에 대한 인식이 대학생들의 정치의식에 미치는 영향을 경험적으로 분석하였다는 것이다. 기존연구와의 차이점은 청소년기의 생활환경의 요소들을 중심으로 이러한 것들이 청소년 정치의식에 미치는 영향을 살펴보았다는 것이다. 본 연구는 2009년 청소년정책연구원에서 조사한 실태자료를 참고하였으며 대학생 1363명을 대상으로 분석한 것이다. 본 연구를 위한 분석방법으로는 SPSS 13.0을 통한 기술통계와 회귀분석을 사용하였으며, 연구결과는 다음과 같다. 첫째, 대학생들의 정치에 대한 관심도는 정치의식에 유의미한 영향을 미칠 가능성이 있다. 둘째, 본인과 형제, 자매, 부모, 이웃과의 사회 정치 대화정도는 청소년 정치의식에 긍정적인 영향을 미칠 수 있다. 셋째, 대학생들의 매체 즉, TV, 라디오, 신문, 잡지, 인터넷 등을 통한 사회 및 정치에 대한 접촉정도는 그들의 정치의식과 유의미한 상관관계가 있을 가능성이 있다. 이러한 결과는 대학생들의 사회 및 정치에 대한 관심 및 담론의 기회를 넓히고, 다양한 매체를 통한 사회 정치의 참여의 경험이 필요하다는 것을 알 수 있게 한다. 또한 실생활을 통한 청소년들의 사회 정치의식에 대한 교육의 접근방법에도 도움이 될 수 있을 것이다.

This study examines the relationship between social media marketing and brand loyalty through brand trust. Respondents were drawn from customers of McDonald’s, Malang City, East Java Province, Indonesia. For this study, 130 questionnaires were distributed and data were analyzed using the Structure Equation Model (SEM) version 22 of the AMOS (Analysis of Moment Structure) application. The results showed that social media marketing had an impact on increasing McDonald’s brand trust and brand loyalty. Brand trust influences brand loyalty and brand trust can mediate the influence of social media marketing on McDonald’s brand loyalty. The findings prove that brand trust can mediate the effect of social media marketing on customer loyalty to McDonald’s brand. These results can be explained by the fact that marketing strategies through social media marketing, such as making it easy for customers to get information related to McDonald’s on social media, can contribute to customer trust and that trust is formed because McDonald’s always pays attention to the quality of the products offered. Brand trust can mediate the influence of social media marketing on customer loyalty to McDonald’s brand. This means that information related to McDonald’s on social media is proportional to the quality of the product offered.

The implementation of physical or social distancing during the Covid-19 pandemic has an implication on the shifting of conventional to online business activities. This study aims to explore how financial support, perceived benefits, external pressure determine social media marketing as well as understanding the role of internet and e-business technology (IEBT) that occurs in this relationship. This study adopted a quantitative study with Structural Equation Modeling (SEM)-based variance Partial Least Square (PLS), which aims to enhance understanding of the relationship between variables. The surveyed population of this study came from 123 small- and medium-sized enterprise (SME) owners in East Java of Indonesia, using an online survey and selected with the convenience random sampling method. The findings of this study indicated that the perceived benefits and external pressure have a positive effect on the adoption of IEBT. However, financial support failed in explaining SMEs’ adoption of IEBT. This study confirmed that the adoption of IEBT has successfully mediated the influence of financial support, perceived benefits, and external pressure on social media marketing. Despite the samples solely collected from East Java, this study is the first step in research related to the social media marketing in SMEs in Indonesia.

The purpose of the research is to analyze the behavioral intention to adopt social media in SMEs affected by the COVID-19 crisis, based on the TOE Model. This study uses the TOE framework as a theoretical basis. This research is important because COVID-19 has destroyed most of the SMEs, and SMEs are exposed to social media technology to market their products. The success of social media adoption has helped SMEs to be able to rise from adversity. Respondents in this study were 250 SMEs in the Special Region of Yogyakarta, Indonesia. The data analysis technique used is structural equation modeling with AMOS. The results of this study indicate that SMEs affected by the COVID-19 crisis have a high awareness of social media and have a high intention to adopt social media as a way to market their products and connect with customers. The intention to adopt social media is significantly influenced by the technological context, organizational context, environmental context, and social media awareness. The findings of this study suggest that in times of crisis due to the COVID-19 pandemic, the Government support is needed. The Government needs to open services for SMEs whose businesses are affected by the pandemic.

This research article investigates the way eWOM in social media influences the formation of destination image through development of trust and satisfaction for the potential tourist. The research involved administering an 18-point questionnaire taking online reviews, tourist involvement, and eWOM, destination image components of trust and satisfaction as variables. Data was collected from 554 individuals forming a cross-section of social media users and analyzed using multi-variate techniques (Reliability, CFA, and SEM). Results indicate a positive and significant relationship between all except online review and destination trust and satisfaction. Indirect and direct effects indicate that eWOM fully mediates the relationship between destination satisfaction and involvement and partially mediates the relationship between destination trust and involvement. In the case of online reviews, eWOM acts as a full mediator between destination trust and destination satisfaction for the future traveler using social media. The study proposes that components of image vary depending upon the degree of involvement, volume online reviews and eWOM generated also termed as ‘virality’ and these in turn influence the intention to revisit or recommend a destination. The study highlights its utility for National Tourist Organizations (NTOs) and online travel intermediaries to enhance destination marketing efforts.

Electronic commerce is becoming a significant hub for sourcing products/services which helps organizations to connect with potential customers and gain competitive advantages, though little empirical work focuses on small businesses operating in developing countries to date. Increasingly, companies are looking to utilize social media to connect with stakeholders and pursue several benefits. This study aims to investigate the technological, organizational, and environmental (TOE) factors that influence small- and medium-sized enterprises’ (SMEs) social media (SM) adoption in developing countries. This study used a closed-ended questionnaire to collect data from randomlyselected respondents (owners, executives, and managers) from SMEs in Pakistan. SMART PLS version 3.2.8 was used for path analysis of 316 responses and for structural equation modeling. The research findings include the direct influence of TOE factors (relative advantage, interactivity, visibility, top management support, and institutional pressure) on SMEs’ SM adoption, and in turn SM adoption also has a positive influence on SMEs performance. Moreover, the coefficient of determination of the study showed that 77.7% of the variation in SM adoption occurs because of TOE factors and 29.8% variation in SMEs occurred because of SM adoption. This paper has implications for practitioners and scholars interested in exploring the SM adoption and usage by SMEs.

As more consumers are interested in sustainability issues and evaluate brands based on their social responsibility issues involved, firms are using social media platforms in order to communicate with consumers about Corporate Social Responsibility (CSR) activities. However, the current literature focuses mostly on factors drive engagement of promotional messages, while little evidence was found in the literature on how to design effective CSR messages on social media to engage consumers. Using over 3,000 branded posts on Facebook and Twitter, this research explores factors that help CSR messages become more engaging in social media. The results show that, on average, CSR messages had a negative significant effect on consumer engagement. However, CSR messages became more engaging when designed with emotional appeals, longer texts, and a hashtag. While marginal, CSR messages with informational appeals and humor undermined the effect of CSR messages on engagement. Finally, we explore different types of CSR messages by their beneficiary scope and the role of brands in the message and discuss what message contents drive more engagement in social media. This research contributes to the academic literature and managers by providing new insights on how to design CSR messages for effective communications in social media.

In the information age, the relationship between customers and companies is not just about the relationship between consumers and products provided. In the online shopping context, customers are connected to the companies through the Internet before and after the purchase. The concept of "customer engagement" is also formed during the process. In short, customer engagement is the connection that an enterprise establishes with customers through marketing activities. Specifically, customer engagement refers to a series of transactions or non-dealing behaviors of the enterprise, including the interaction between enterprise and the customer, customer's participation behavior and other related behavior, which affects the customer's enthusiasm, social interaction, and conscious participation. Based on the emerging concept of customer engagement, this research keeps up with latest dynamics of online environment and tries to explore the role of customer engagement in the context of social media. Since there are a variety of social media platforms existing, we choose one of the most popular social media platforms in China, WeChat, to investigate the impact of customer engagement on brand loyalty to help companies improve customer's brand loyalty through social media marketing.

The paper aims to investigate the relationship between firm size and organizational actions on adopting social media for corporate reputation management. The sample group of 198 companies is selected with a simple random sample method from the New York Stock Exchange (NYSE) listings: Sixty nine companies were from the Fortune 500 listings, seventy one companies from the NYSE midsize capitalization and fifty eight companies from the NYSE small capitalization listings. This study employs cross tabulations and Chi-square analysis, and the Kruskal-Wallis that enables the comparison of three samples that are independent. The results of the study show that (1) large firms have more social media ownership than small firms, (2) large firms respond to social media posts at a greater frequency and quickly than small firms, and (3) firm size is less likely associated with response styles to social media for online reputation management. The results show that reply time and response styles of organizations to social media customers in the 2015 survey has no significant change compared to that of 2011. There appears to be a pervasive lack strategic framework as most firms in the study were found not to be adequately monitoring or leveraging social media communication for their reputation management.

Purpose - This study aimed to identify the sub-dimensions of fashion social media quality (information quality, social quality, service quality, system quality) and investigate how they affect purchase intention through fashion information use behavior (information acceptance, information diffusion). Research design, data, and methodology – Data collection was carried out twice for systematic verification of the research model. In the first data collection, the reliability and validity of research variables were verified through 238 respondents and questionnaires were revised and supplemented based on their responses. In March 2018, the final survey was conducted from 755 respondents the age of 20 to 49. Using SPSS 23.0, descriptive statistics, exploratory factor analysis, correlation analysis were performed. In order to test hypotheses, structural equational modeling technique was employed using AMOS 23.0. Results - First of all, fashion Social media quality consists of four factors including information quality, social quality , service quality and system quality. Second, fashion Social media information quality, social quality , and system quality were shown to have a positive(+) effect on information acceptance behavior, and social quality , service quality and system quality were shown to have a positive(+) effect on information diffusion behavior. It was also determined that the acceptance and diffusion behaviors of fashion information through fashion Social media had positive(+) influence on purchase intention. Conclusions - This study holds academic significance in its identification of the components of fashion Social media quality and for conducting an empirical analysis on the causal relationship between fashion information acceptance and diffusion behaviors, and purchase intention. The results of this study indicate that fashion involvement is the key factors in determining the quality of Social media, the acceptance of information through Social media, and, by extension, the purchase of fashion products. Practitioners in the fashion industry may use the findings of this study in order to build more effective Social media strategy.

Purpose – The research aimed to reveal real decisional behavioral of management institutes in India for social media marketing usage, and analyses of empirical elements of social media consumption pattern. Research design, data, and methodology – The investigation was based around a research methodology using quantitative analysis with appropriate statistical techniques on random surveys of consumers, detailed exploratory and confirmatory factor analyses are applied to assess the empirical validity of the model and multiple regression employed using R studio edition to validate the reliability of the developed models. Results – A new conceptual framework is proposed – the management institutions decision model, providing a tool for effective and more focused decision-making strategies for developing better utilization techniques for social media. Management institutions have different requirements based upon objectives and resources available. The evidence suggests that the administrators need to be more aware of consumer indicators when targeting and designing social media marketing strategy. Conclusions – The research was based on samples and not the entire population of target consumers, providing limitations. As an inferential statistical method was chosen, the results might be susceptible to inaccuracy. The model developed from different age users, thereby providing rich perspectives into social media usage pattern.

This study developed and tested the impact of hallyu 4.0, social media, and consumer ethnocentrism on the decision to purchase Korean products of Generation C in Vietnam. Both qualitative and quantitative methodologies were utilized in this study. Qualitative research was first carried out with in-depth interview, conducted to derive measurement items for the interested constructs. Quantitative research used cross-sectional field design by pilot study and official study. The model was tested and developed using data collected by questionnaires, from a sample of 575 respondents, by both electronic and paper surveys with non-probability and convenience sampling techniques. SPSS 20 and AMOS 20 software were employed to analyze the data. The results of structural equation modeling showed that hallyu 4.0, social media, and consumer ethnocentrism influenced the intermediates variables: subject norms, trust, attitude and behavioral intention and influenced purchase decision. The hallyu 4.0, social media, and consumer ethnocentrism are independent variables. They impact purchase decision through mediating variables such as trust, subjective norms, attitude and behavioral intention. Social media influences not only to trust but also to subjective norms. Subjective norms influence on purchase decision. This study also discovers an interesting fact that trust and attitude variables have an impact on behavioral intention and purchase decision.
