The advent of fintech is blowing a new wind into the financial industry. New business models have been created and consumers’ access to financial services is higher than ever. Internet-only banks based on advanced information technologies have emerged as a leader in the fintech industry, and these banks are fiercely competing with large banks using internet banking as a weapon to attract new customers. The purpose of this study is to explore the factors that influence customers’ intention to switch to internet-only banking services from traditional internet banking services in Korea. To this end, a research model was developed based on the push-pull-mooring model (PPM), which is a migration theory. The research model was analyzed using partial least squares structural equation modeling (PLS-SEM). The findings will provide the practitioners of the new internet-only bank with strategic guidance for attracting new customers and help practitioners of traditional banks to retain current customers.

Although numerous studies have been conducted on the use of self-service technology (SST), little is known about the importance of the situation for individuals’ acceptance of SSTs. This study proposed the situational dependency construct and analyzed the role of the construct in the use of SSTs. To conduct an empirical analysis, a research model combining the situational dependency variable with the perceived usefulness and perceived ease of use of the technology acceptance model variables, which are the most frequently used in studies related to SSTs, was developed. A total of 213 valid data were collected through questionnaires and analyzed using confirmatory factor analysis and path analysis through structural equation modeling. The results showed that situational dependence influenced attitude toward using along with perceived ease of use and perceived usefulness and that situational dependence had a strong influence on intention to use. This study provides strategic insight for practitioners to lead acceptance of SSTs.

The smart farm, a future-oriented farm operation that integrates information and communications technologies, is an emerging trend in agriculture. This study investigates the factors affecting the adoption of the smart farm in Korea and analyzes them empirically. The research model is based on Rogers' innovation diffusion theory and existing models of adoption of information technology in organizations. The model proposes that adoption of innovative technology is influenced by relative advantages, complexity, and compatibility of the technology, the innovativeness and IT knowledge characteristics of the CEOs, financial costs, human resource vulnerability and lack of skills, competitive pressure, government support and the change to the digital environment. These factors were categorized according to TOE framework, investigated, and empirically tested using survey data to determine their influence on the adoption of smart farms. The results showed that the compatibility of technology, financial costs for the organization, and the digital environment change influence the adoption of smart farms. This study suggests practical implications for the adoption of smart farm technology based on the results.

Use of mobile instant messaging has grown tremendously in the last few years, and is positioned as a platform for mobile business. This study aims to explore how an individual’s intention to use mobile instant messaging is influenced by technical and individual characteristics as well as social influence factors. A research model based on perceived usefulness and perceived enjoyment, including technical characteristics (ease of use and convenience), individual characteristics (computer playfulness and personal innovativeness), and social influence factors (perceived critical mass and identification) was developed. The model was empirically analyzed using structural equation modeling with data from mobile instant messaging service users in Korea. The results indicate that most of the proposed technical characteristics, individual characteristics, and social influence factors have impacts on perceived usefulness and/or perceived enjoyment, which form the intention to use mobile instant messaging. Our findings provide strategic guidelines for service providers with respect to the development and operations of mobile instant messaging.

Although the role of motivation has been emphasised in knowledge-sharing literature, traditional motivation theories, such as self-determination theory (SDT), have not been actively used as a research framework in knowledge-sharing research. The purposes of this study are twofold. The first objective is to propose a model, based on SDT, to test the effect of the three basic psychological needs – perceived competence, perceived autonomy and perceived relatedness – on knowledge-sharing behaviours in virtual communities. The second objective is to explore the effects of familiarity and anonymity on the basic psychological needs to better understand individuals’ knowledge-sharing behaviours in virtual communities. The results show that perceived competence and perceived relatedness influence knowledge-sharing behaviours in virtual communities; however, perceived autonomy does not influence knowledge-sharing behaviours; familiarity influences positively perceived competence and perceived relatedness, and anonymity influences negatively perceived autonomy and perceived relatedness.

Since digital piracy has posed a significant threat to the development of the software industry and the growth of the digital media industry, it has, for the last decade, held considerable interest for researchers and practitioners. This article will propose an integrated model that combines the theory of planned behavior (TPB) and ethics theory, the two theories that are most often used in digital piracy studies. Data were obtained from university students in China, and the model was examined using the structural equation model (SEM). The results show that moral obligation and justice, derived from ethics theories and TPB variables, such as attitude, subjective norms, and perceived behavioral control, influence the behavioral intentions of individuals to commit digital piracy. The attitude of individuals toward digital piracy is also found to be influenced by perceived benefits, perceived risk, and habit.

This article introduces an Online Store Success Model (OSM) that reflects the characteristics of information systems, marketing, and e-commerce, and then empirically test the model. The OSM has five dimensions: system quality, information quality, service quality, trust, and customer loyalty. The model posits the causal relationships between the dimensions. In order to empirically test the model, a research model is developed and empirically analyzed by structural equation modeling using data from 244 customers on 69 online store websites. The results show that system quality significantly influences service quality and trust; information quality significantly influences service quality and customer loyalty; service quality also significantly influences trust and customer loyalty; and trust has a significant influence on customer loyalty.

Although the research on organizational citizenship behaviors (OCBs) has increased dramatically in diverse fields during the past decade, little is known about the OCBs in the information systems area. The purpose of this study was to explore the effect of OCBs on enterprise resource planning (ERP) system success. In order to perform empirical analyses, measurements on the OCBs constructs based on the five dimensions of [Organ, D.W. (1988). Organizational citizenship behavior: The “Good Soldier” syndrome. MA: Lexington Books]: altruism, conscientiousness, courtesy, civic virtue, and sportsmanship were developed, and the research model including the relationships between the OCBs constructs and ERP system success variables of information quality, work efficiency, and intention of IT innovation was proposed and empirically analyzed using structural equation modeling. The contribution of this study is to provide strategic insights for successfully managing ERP systems by identifying the effects of organizational citizenship behaviors in ERP context.
