        This study aims to help companies with efficient investment and marketing strategies by empirically verifying the impact on satisfaction and purchase intention for artificial intelligence-based digital technology supported shopping assistants introduced in e-commerce. Frequency, factor, SEM, and multiple group analysises were conducted using SPSS 26.0 and Amos 26.0. As a result, first, motivated consumer innovativeness elements of AI shopping assistant were derived into a total of four categories: functional, hedonic, rational, and reliable. Second, in the order of hedonic and rational, satisfaction with the AI shopping assistant was significantly affected, and in the order of rational and functional, purchase intention was significantly affected. The satisfaction with the AI shopping assistant did not affect the purchase intention. Third, in the case of hedonic, the AI-preferred group had a more significant effect on satisfaction than the human-preferred group, and in the case of rational, there was no difference by group in purchase intention. Thus, it was found that consumers prefer AI shopping helpers for e-commerce because they can shop reasonably and are functionally convenient. Therefore, when introducing AI shopping assistants, it is essential to include content that can compare and analyze fundamental information, such as product prices, as well as search functions and payment system compatibility that facilitate shopping.

        This study analyzed the effects of fashion creators’ innovativeness and attractiveness on consumer response and orientation toward a sustainable relationship in personal media. A survey was conducted with consumers aged in their 20s and 30s who had experience in sharing video content or writing comments and participating in fashion creators’ real-time broadcasting of personal media. The results show that the innovativeness of fashion creators was classified into originality, opinion leadership, variety, and adventurous spirit, while attractiveness was classified into physical, social, and professional attractiveness. Consumer responses were classified into either emotional or cognitive responses, and sustainable relationship orientation was classified into communication, sharing, and relationship sustainability. The originality and variety of the fashion creators positively affected the emotional and cognitive responses of consumers. Adventurous spirit positively affected emotional response, whereas opinion leadership positively affected cognitive response. In addition, the social and professional attractiveness of fashion creators positively affected consumers’ emotional and cognitive responses. Emotional and cognitive responses positively affected consumers’ sustainable relationship orientation. The originality and opinion leadership of the fashion creators positively affected the three factors of sustainable relationship orientation, while variety positively affected communication and relationship sustainability. Fashion creators' social and professional attractiveness positively affected the three factors of sustainable relationship orientation, and physical attractiveness positively affected relationship sustainability. The results of this study are expected to provide useful data on the direction of fashion startups using personal media and marketing as well as distribution strategies in the fashion industry.

        The study proposed a dual-path model to examine the relationship between customer perceived hotel innovativeness and customers’ interactivity, building the signaling theory. The model was tested with hotel customers from China. The findings suggest that customers’ perceived hotel innovativeness not only has a positive and direct impact on their interactivity, it also indirectly contributes to customers’ interactivity via two indirect paths, one featuring a cognitive-economic motivation pathway and the other featuring an affective-motivation pathway.

        Smart healthcare clothing combines IoT, new technology, and clothing construction to perform specific care functions, and its utility has been expanding rapidly within aging and diversified societies. However, the related market remains at an early stage of development due to limited regulation, lack of consumer awareness, and the need for not only technical development but promotion plans for potential users. This paper aims to analyze factors influencing purchase intention for smart healthcare clothing with biosignal monitoring, including variables in the Technology Acceptance Model (TAM), clothing attributes, health-related lifestyle factors, and fashion innovativeness. A survey was conducted on a sample of 300 males and 300 females ranging in age from 20 to 50 years, and data were analyzed using SPSS 21.0. The results show that perceived usefulness, perceived aesthetic attributes, health responsibility, and fashion innovativeness were overall significant predictors of using smart healthcare clothing. Additionally, perceived ease of use and physical activity in the male subsample, and perceived compatibility within the female group, also had significant effects. Furthermore, age was a determining factor; for subjects in the 30s age group, perceived usefulness, compatibility, and health responsibility had significant positive associations. The results of this study can provide basic guidelines for designing merchandising plans to expand user acceptance of smart healthcare clothing.

        This study investigates the effects of the type of advertisement, brand extension, and consumer innovativeness on the credibility of fashion advertisements. The factorial design is constructed as a 2(type of fashion advertisement: general vs. cross-media) × 2(consumer innovativeness: high vs. low) × 2(the type of fashion brand extension: similar vs. dissimilar) three-way mixed design in which consumer innovativeness is the between-subjects variable. Subjects of this study included 210 men and women in their 20s and 30s who resid in Seoul and had SNS experiences. Frequency analysis, credibility analysis, three-way ANOVA, and simple interaction analysis were conducted using the SPSS 20.0 statistics package. The results are as follows: First, the type of fashion advertisement had a significant effect on advertising credibility. Cross-media advertisements had a more positive effect than general advertisements on all of the dependent variables. Also, the type of brand extension and consumer innovativeness showed significant effect on advertising credibility and the interaction effect between the type of fashion advertisement and consumer innovativeness was significant. Lastly, the effect of different types of brand extensions on advertising credibility showed a significant difference according to consumer innovativeness. Thus, a marketing strategy using cross-media advertising is proven to be effective in gaining consumer trust for a fashion brand.

        Judging by the volume of marketplace failures, it seems that consumer innovators make biased assessments about the value of the innovativeness of new products (Gourville, 2006; Mugge & Dahl, 2013). Research suggests that consumer evaluate offerings based on form (i.e. visual appeal) and function (i.e. utilitarian appeal) (Gourville, 2006; Talke, Salomo, Weiringa & Lutz, 2009; Mugge & Dahl, 2013). In relation to innovative new products, the consumer decision-making path is unclear and the optimal mix of continuity and discontinuity across form and function is unknown. The lack of information regarding how marketers should appropriate resources to maximise returns thus, is an issue that requires resolution. To help resolve this gap, we seek to address two important practical marketing questions in the context of innovative new product introductions: (Q1) What is the impact that discontinuity and continuity across form and function have on new product adoption, and (Q2) What if any, are the underlying mediating mechanisms for different markets? To address these, we collected data from participants based in the United States of America through an online experiment. The participants were presented with four products, comprising variations of a digital camera based of continuity and discontinuity across form and function. The findings revealed that the same product could lead to differing perception of value based on the participant being an innovator or an adapter. The differing perceptions were explained by differences in assessments of potential costs and benefits from the product. Based on the findings of the study managerial recommendations on targeting the right segment for the right product were offered.

        Prior research found a firm’s strategic orientation has a key impact on product innovativeness performance (Ozkaya et al., 2015). Both marketing orientation and learning orientation help firms to develop new product designs, generate innovative ideas, and achieve a better business performance (Narver & Stanley, 1990; Chuang, Morgan & Robson, 2015; Calantone et al, 2002). In line with prior studies, the purpose of this research is to investigate the mediating role of absorptive capacity (ACAP) (Cohen & Levinthal, 1990) on the effect of a firm’s strategic orientation (i.e., marketing orientation and learning orientation) on product innovativeness. We further investigated how environmental uncertainty moderates the effects of market orientation and learning orientation on product innovativeness. Survey method is adopted to collect data from Chinese manufacturer SMEs in the IT industry. 318 questionnaires were collected and analysed. CFA result shows that all constructs meet minimum requirements for reliability and discriminant validity test. Structural Equation Model (SEM) test reveals that both learning orientation and competitor orientation have significant impacts on product innovativeness, and ACAP plays partial meditation roles to effects from learning orientation to product innovativeness, and competitor orientation to product innovativeness. Customer orientation does not show a direct effect on product innovativeness, but is fully mediated by ACAP. We further tested whether the model is moderated by environmental uncertainty (EU) and result shows that EU only moderates the impact from learning orientation to product innovativeness. By developing a model of strategic orientation– absorptive capacity- product innovativeness, we contribute to the extant literature in strategic marketing.

        기업이 지속적인 경쟁우위를유지하기 위해서는 환경특성의 변화에 적절하게 대응할 수 있는 혁신역 량이 수반되어야 한다. 기업의 혁신역량은 어떠한 환경의 변화에도 적극적으로 대처할 수 있어야 하며 이는 탐험이나 활용의 특정한 한 가지 혁신전략이 아닌 두 가지 혁신역량 전략을 적절하게 균형을 유지하 며 동시에 추구하는 양면성 혁신을 선택하게끔 하고 있다. 이것이 요즘 기업경영의 화두로 작용하고 있는 조직의 양면성(ambidexterity)이며 조직에 경영관리방식에 새로운 혁신적인 방법으로 채택하고 있다. 조직 양면성에 대한 연구는 March(1991)의 연구이후 선행요인 및 결과요인들에 많은 후속 연구가 있 어왔다. 이와 같은 중요성에도 불구하고 한국기업을 대상으로 한 조직양면성의 선행요인들과 경영성과 및 이들의 매개관계에 대한 실증적 연구는 부족한 편이다. 본 연구에서는 기존문헌고찰을 통해 조직 양면성의 중요한 상황요인으로 환경의 동태성과 혁신성을 고려하고자 한다. 그리고 조직 양면성의 선행요인인 환경동태성과 혁신성이 기업성과에 미치는 직접효과 및 조직 양면성의 매개효과를 파악하기 위하여 실증적 연구를 실시하였다. 본 연구는 국내 혁신형 중소기업 108개 기업을 대상으로 실증적 연구를 분석한 결과 환경의 동태성과 혁신성은 조직의 양면성에 긍정적인 영향을 주고 있으며, 또한 조직 양면성은 환경의 동태성과 혁신성이 기업성과에 미치는 인과관계에서 중요한 매개역할을 하고 있다는 사실을 확인할 수 있었다.

        Customers are regarded as the key intangible assets of a company. It is necessary to have the capability to anticipate customer value. The study discusses the relationship among customer value anticipation, product innovativeness, and customer lifetime value from customer perspective. 178 MBA students were surveyed by questionnaire in this study. The results show that customer perceived customer value anticipation can significantly influence product innovativeness. Product innovativeness not only positively affects customer lifetime value, but also plays a partial mediating role between customer value anticipation and customer lifetime value. Both functional and emotional advertising can play a moderating role on the relationship between product innovativeness and customer lifetime value. At the end, managerial implications are discussed.

        Vertical alliances for collaborative new product development in interfirm relationship have been an ongoing theme of strategy and marketing research to cope with fast changing environments, and to continuously innovate in the marketplace. However, no study has yet examind both direct and indirect effects of vertical alliances on new product performance under high technology turbulence. As alliance partners seek to enhance their collaboration and performance, the relational nature of business relationships and structural network positions can influence firm innovativeness and subsequent new product performance. Using survey data of 146 firms collected in Turkey, this study shows that while firms form stronger cooperation under conditions of high technology turbulence, the impact on firm innovativeness and new product performance is contingent upon network positions and information exchange. The findings indicate that indirect effects of vertical alliance portfolio and information exchange enhance new product performance through firm innovativeness. Vertical relationship structures facilitate firm innovativeness with enhanced exploration but may not have a positive direct effect on new product performance. Furthermore, the effect of information exchange on new product performance is contingent upon information exchange which enhances firm innovativeness.

        Ethical consumption, including ethical tourist behavior, is of growing importance to governments, companies and consumers and consumers increasingly act accordingly (Sheth, Sethia, & Srinivas, 2010). Most ethical tourist behaviors conform to service industry characteristics, being intangible, heterogeneous and fusing production and consumption. Adopting ethical tourist behaviors (ETBs) requires activities, practices or ideas that consumers perceive as new, components that are key characteristics of innovations (Goldsmith, d’Hauteville, & Flynn, 1998; Rogers & Shoemaker, 1971). Studies frequently explore environmentally friendly behavior of a specific tourist segment - existing eco-tourists (Dolnicar, Laesser, & Matus, 2010) and limit their focus to environmental issues. In line with the World Tourism Organization’s conceptualization that highlights the importance of environmental, cultural and sociological aspects (http://ethics.unwto.org/en/content/global-code-ethics-tourism), this research uses the term ethical tourist behavior and investigates the concept using a sample of ordinary tourists. Consumer innovativeness has been defined as the “degree to which an individual is relatively earlier in adopting an innovation than other members of his system” (Rogers and Shoemaker, 1971, p. 27). Innovativeness, the propensity to adopt, is focusing on an individual’s behavior relative to other people in a population (Goldsmith & Hofacker, 1991; Im, Bayus, & Mason, 2003). Diffusion of innovation, investigating the spread of an innovation through the population, is frequently modeled using an S-curve (Rogers, 1995). ETB includes a wide range of activities with the behavior expected to be cumulative; for example somebody who chooses to stay in tourist accommodations with environmental certification is also likely to recycle. Cumulative patterns fit the Rasch Model (RM) (Rasch 1960/80). Well established in education and psychology, the model gains increasing attention in marketing (for example Ewing, Salzberger, & Sinkovics, 2005; Ganglmair-Wooliscroft & Wooliscroft, 2013; Salzberger & Koller, 2013; Wooliscroft, Ganglmair-Wooliscroft, & Noone, 2014). The probabilistic RM is based on a mathematically elegant equation (Bond & Fox, 2007), specifying that people who undertake more extreme ethical tourist behavior will also have a higher probability of engaging in (and subsequently agreeing to or endorsing a) comparably easier ethical tourist behavior. Item Characteristic Curves (Bond & Fox, 2007) embody the theoretical curve for an item’s endorsability. If empirical answer patterns follow the theoretical curve (and a number of other fit statistics are satisfactory) the item fits requirements of the Rasch Model. This study develops an ETB hierarchy and explores parallels between characteristics of Rasch Modelling (Rasch, 1960/80) and the Adoption of Innovation (Rogers, 1995). Additionally, the study explores variables influencing the level of ETB, representing actualized ethical tourist innovativeness. The final ETB hierarchy contains of 27 ethical tourist behaviors that relate to a wide range of holidays. Using a cross-sectional sample of 322 respondents, representative of the population, the research finds that ethical tourist behavior diffuses through the population in a structured, ordered sequence, providing support for parallels between the Diffusion of Innovation Model (Rogers, 1995) and Rasch Model’s ICC characteristics. Most respondents undertake only a small range of ethical tourist behaviors, indicating that many ethical issues are at a very early stage of the diffusion process. The level of ethical tourist behavior adaption – operationalized through respondent’s position on the ETB hierarchy is influenced by high importance of universalism, age and gender.

        Referral marketing plays an important role in promoting new products. When it comes to innovative agricultural products, early adopter’s review or recommendation has a more critical impact on follower’s purchase decision making. Hence, understanding of consumer’s characteristics and needs play more important role in success of innovation. More particularly, other researchers pay attention to the role of consumer innovativeness. This study attempts to fill this gap in knowledge between innovative propensity of consumer and her/his intention to generate positive word of mouth about new agricultural products. Furthermore, in this paper, we adopt Vandecasteele and Geunes’ motivated consumer innovativeness model to investigate consumer innovativeness in extrinsic motive and intrinsic motive level, and examine the moderating role of referral efficacy. For empirical verification, survey method is used for data collection. Partial least square (PLS) is adopted to analyze the data. Finally, several theoretical contributions and practical implications are discussed.
