본 연구는 혁신확산이론과 관련 선행연구를 기반으로 사용자의 핀테크 결제 서비스 사용 영향요인을 서비스와 사용자 측면으로 분류하여 파악하고 인과관계를 실증 검증하였다. 사용자 수용에 영향을 미치는 서비스 특성으로 복잡성, 혜택, 서비스 제공자 신뢰와 인지된 위험을 서비스 특성으로, 개인 혁신성과 보안사고 경험을 사용자 특성으로 분류하여 연구모형을 구성하였다. 이항 로지스틱 회귀분석 결과 인지된 위험과 사용의 복잡성, 보안사고 경험은 사용자의 핀테크 수용에 부정적인 영향을 미치며 개인혁신성은 긍정적인 영향을 미치는 것으로 나타났다. 추가로 인지된 위험이 핀테크 서비스 수용에 미치는 부정적인 영향을 강화하는 보안사고 경험의 조절효과 역시 유의미하게 나타났다. This study aims to understand crucial factors affecting user's Fintech payment service adoption. On the basis of innovation diffusion theory and prior Fintech literature, this study classifies the influence factors of users' adoption of Fintech payment service into two dimensions - service dimension containing complexity, perceived benefit, trust in service provider and user dimension containing personal innovativeness and security breach experience. The data analysis results using binary logistic regression shows the negative direct effects of perceived risk, complexity, security accident experience on user's service adoption are statistically significant. Personal innovativeness has a positive effect on user's Fintech payment service adoption. The moderation effect of security accident experience is also significant at p<0.05.

Purpose Global fintech industry is proliferating. Although domestic investment in fintech service is also increasing fast, user acceptance of fintech payment service seems slower than expected. Previous fintech literature mainly focuses on overall characteristics and technical aspects of fintech including security issues and explores factors affecting the service adoption. This study aims to examine crucial factors affecting user’s resistance intention to fintech payment service adoption. The research model was formulated based on innovation diffusion theory and status quo bias theory and validated empirically. Design/methodology/approach The proposed research model was empirically validated with 149 responses from college students who have used fintech payment service. The component-based SEM was employed for data analysis. Findings The significant findings are as follow. First, compatibility has significant negative effect and complexity, and perceived risk has a positive effect on user resistance. Second, institutional trust does not show a significant effect on user resistance but has an indirect effect through the mediation of trust in service provider. Finally, trust in service provider shows the significant negative effect on user resistance.

This study explores the factors influencing user satisfaction of mobile IPTV and their relationship. We formulate the research model based on characteristics of mobile device and IPTV. Responsiveness, contents satisfaction, price satisfaction, aesthetic simplicity, network quality are proposed as essential antecedents of mobile IPTV satisfaction. We also suggest network quality and gender as moderators. Our data analysis with 297 mobile IPTV users shows contents and price have significant positive effect on mobile IPTV satisfaction. Network quality shows positive moderation effect on the relationship between responsiveness and satisfaction.

Although e-commerce is growing fast, e-commerce consumers are still under higher risk and uncertainty in the comparison of the traditional commerce`s. Consumer review boards of online shopping malls are good measures to help buyer`s decision making, and should be managed effectively by sellers. We formulate the research model on consumer trust formation on seller managed web review boards on the background of previous literatures on e-WOM and trust. Our data analysis with 368 samples shows seller`s reputation, e-service quality, perceived reviewer`s benevolence and ability have significant positive effect on the trustworthiness of the board. Product involvement shows weak negative moderation effect on the relationship between perceived reviewer`s benevolence and trustworthiness of review boards.

Purpose Although companies occupied the network market take the advantageous position first and can be successful in securing users over a certain size, it is important to satisfy the customers' demand and prevent the outflow of users toward a new alternative SNS. What is more, there are frequent changes in the flow of users toward new SNSs. Despite these dynamic market circumstances, there is a lack of research to explain the switching behaviors of SNS users. Design/methodology/approach The objective of this study is to explain and verify a specified migration theory(Push-Pull-Mooring model) focused on SNS fatigue in the psychological point of view, as well as reviewing previous studies on functional and technical characteristics of SNSs themselves. Moreover, this study tried to highlight factors affecting users actual SNS switch rather than their switching intention. Findings According to the statistical analysis, the most influenced pull factor to switch SNS was the alternative attractiveness. On the other hand, undesired relationship burden, service innovation and important mooring factors to prevent users' SNS switch. This study has a significant contribution to the theory, which analyzed users' actual SNS switch, and examined SNS users' psychological factors(SNS fatigue), reviewing the characteristics of existing services. To secure more users and to keep them, companies providing social network service need to develop differentiated strategies by analyzing psychological characteristics of various users.

온라인 후기 유용성 영향요인 연구

온라인 후기는 전자상거래에서 소비자의 불확실성을 감소시키는 중요한 수단이다. 온라인 소비자는 구매 결정을 위하여 다른 소비자의 구매 후기에 많이 의존하고 있다. 온라인 후기를 효과적으로 활용하는 것은 소비자의 구매 위험을 감소시킬 뿐만 아니라 전자상거래 업체의 성과에도 중요한 영향을 미친다. 따라서 소비자의 온라인 후기 유용성 인식에 영향을 미치는 요인을 파악하는 것이 중요하다. 본 연구는 전자상거래에서 후기 수용자의 인지적 특성과 제품 속성을 중심으로 소 비자가 인식하는 후기 유용성에 미치는 영향을 파악하였다. 228명의 설문 응답을 분석하여 연구모형을 실증 검증하였다. 자료 분석 결과, 구매자의 후기 유용성 인지에 평판을 제외한 인지욕구, 후기의 신뢰성과 후기 작성자 역량의 유의한 영향을 미치는 것으로 나타났다. 이 중 후기 신뢰성이 가장 큰 영향을 미치는 것으로 나타났다. 또한 인지욕구가 높은 수용자일수록 온라인 후기를 더 유용하게 인식하였다. 제품의 속성에 따른 조절 효과는 유의하지 않은 것으로 나타났지만, 후기 유용성에 미치는 직접적인 영향을 유의하게 나타나 구매하려는 제품이 경험재일 때 수용자는 후기의 유용성을 더 크게 인식함을 확인할 수 있었다. Online buyers increasingly rely on online reviews of previous purchasers. Using online review, customers are able to reduce uncertainty related purchases. Therefore, EC companies need to understand and take advantage of customer’s online review acceptance mechanism. To identify the antecedents of usefulness perception of online review and assess the strength of their effect size, the research model is proposed on the perspective of need for cognition and product characteristics theory. In adition, the research model is empirically tested using PLS analysis with 228 samples. The research results show the most significant antecedents were perceived review credibility and reviewer’s ability. The direct effect of product characteristics on perceived review usefulness is statistically significant, but moderation effect on the relationship between perceived reviewer’s ability and review usefulness is not statistically significant.
