Because the cost of attracting new customers is much higher than the cost of retaining old customers, keeping customers loyal is a crucial issue for service firms. This research explores how relationship quality and switching barriers influence customer loyalty. Relationship quality consists of two aspects: satisfaction and trust. Antecedents of satisfaction and trust are explored. To test the proposed research model, a survey research methodology was used. Paper survey was distributed to mobile phone users in Taiwan. A total of 311 valid questionnaires were returned. Structural equation modeling was used to test hypotheses. Satisfaction, trust, and switching barriers have positive effects on loyalty. In terms of antecedents, it was found that playfulness and service quality impact satisfaction while service quality and intimacy affect trust. From a managerial perspective, this research suggests that practitioner should not only keep improving service quality, but also provide playfulness to ensure customer satisfaction. Service providers should also build relationship quality and switching barriers to reduce the possibility of defection and enhance customer loyalty. 相似文献

The concept of the regional innovation system (RIS) has been developed into an important framework for evaluating innovation performance. The study reported in this paper explores the relationship between the RIS and the firm's innovation system (FIS) according to the basic premise that firms that better utilize sources of information (SI) available within their regional innovation system (RIS) perform better due effect this has in enhancing the firm's technological innovation capabilities (TICs). The different innovation capabilities of a firm are regarded as the key components of the firm's innovation system. The sources of information available within an RIS include external sources (EXT) and external expert organizations, the latter of which are referred to as knowledge-intensive business services (KIBS). This study also explores the dual role of KIBS as both sources of and bridges for innovation in the RIS. Data were obtained through a mailed survey using a self-administered questionnaire. The utilization concept and the dual role of KIBS were verified. The results show that externally available information affects all innovation capabilities of the firm, while external expert organizations affect only the firm's R&D and resources allocation capabilities. This study contributes to the RIS literature by providing empirical evidence on how firms can interact with the RIS by utilizing SI to enhance their TICs and achieve global competitiveness. 相似文献

Our aim is to shed light on the consequences of knowledge management (KM) strategies on firm's innovation and corporate performance. Organisations are not aware of the real implications that KM may have. Based on an empirical study consisted of 310 Spanish organisations and structural equations modelling, results show that both KM strategies (codification and personalisation) impacts on innovation and organisational performance directly and indirectly (through an increase on innovation capability). Also, findings demonstrate a different effect of KM strategies on diverse dimensions of organisational performance. Our conclusions may help academics and managers in designing KM strategic programs in order to achieve higher innovation, effectiveness, efficiency and profitability. 相似文献

Using a case study of the Indian Tobacco Company's (ITC) e-Choupal initiative, the paper empirically analyses the role of information delivery through information and communication technology (ICT) in enhancing decision-making capabilities of Indian farmers. Users of e-Choupal show significantly better decision-making aptitudes, as compared to non-users, on various agricultural practices across the agricultural supply chain. Further, socio-demographic background's of the users such as education levels, the social category they belong to, income level's, and landholding size also play a significant role in impacting decision-making aptitudes. The impact is particularly prominent in production planning and post-harvest and marketing related decisions. Policy implications of these findings are discussed. The study emphasizes the importance of designing ICT enabled information systems to suit the socio-demographic profile of the user groups. 相似文献

Research has identified numerous factors that influence initial technology adoption decisions. However, extant studies consider beliefs to be static rather than dynamic over the adoption time-span. Various models have been employed to identify adoption behavior, pre- and post-adoption, however, there is little research on the dynamics of users’ belief structures over time and the inter-relationships among them. This study aims to investigate the dynamic nature of users’ beliefs and the relationships among their dynamics, i.e., rates of change. We test our research model based on data obtained at three time-windows using a parallel-growth process model. The results reveal that self-efficacy, usefulness and intention to use are likely to be dynamic, and increase with time. The rate of change in self-efficacy influences the rate of change in usefulness, which in turn affects the rate of change in intention to use. This study theoretically contributes to expanding the extant cross-sectional TAM research to include time-phased TAM studies, and highlights the role of self-efficacy as an important determinant of the dynamics. 相似文献

Web portals act as a single point of access to information and services relevant to person's work or personal interests. Market research findings related to Croatian web context report that nowadays horizontal information portals are the most visited sites. Whether they reach their aim of facilitating users’ access to diverse resources and to which extent, remains an open question. In this paper, this issue is addressed by two case studies conducted for summative assessment of Croatian horizontal information portals. Approach assembled expert inspection and user assessment that integrated a number of empirical methods into laboratory-based testing. We report that the results of inspection method were not in agreement with the ones obtained from user test methods. Although differences of this kind have been reported elsewhere, these were not as evident as in these studies. What is very interesting and represents a main contribution of the research is that in both rounds of evaluations this outcome is very sharp and clear. This suggests that we should conduct both kinds of assessments as they seem to be complementary. Evaluation provided some general findings and know-how from the experience and we believe that many readers, both practitioners and researchers, can learn from it. 相似文献

Cost of middle mile bandwidth is declining, but the bandwidth required to meet the needs of broadband subscribers is increasing. The Federal Communications Commission (FCC) has set a Broadband Availability Target of 4 Mbps downstream speed, but average speeds provided to customers in rural areas fall short of this target, indicating a need for more investment in bandwidth capacity. The cost of these upgrades will be substantial and may prove to be a barrier to providing greater speeds to subscribers. We also find that higher capacity and packet technology provide cost savings for the middle mile connections. Population density and geography alone do not explain differences in middle mile costs. 相似文献

This paper deals with the problem of the instability regions of a free-free flexible jointed bipartite beam under the follower and transversal forces as a realistic simulation of a two-stage aerospace structure. The aim of this study is to analyze the effects of the characteristics of a flexible joint on the beam instability to use maximum bearable propulsion force. A parametric study is conducted to investigate the effects of the stiffness and the location of the joint on the critical follower force by the Ritz method and the Newmark method, then to research the vibrational properties of the structure. It has been shown that the nature of instability is quite unpredictable and dependent on the stiffness and the location of the joint. The increase of the follower force or the transversal force will increase the vibration of the model and consequently cause a destructive phenomenon in the control system of the aerospace structure. Furthermore, this paper introduces a new concept of the parametric approach to analyze the characteristics effects of a flexible two-stage aerospace structure joint design. 相似文献

Personal mobile devices such as cellular phones, smart phones and PMPs have advanced incredibly in the past decade. The mobile technologies make research on the life log and user-context awareness feasible. In other words, sensors in mobile devices can collect the variety of user’s information, and various works have been conducted using that information. Most of works used a user’s location information as the most useful clue to recognize the user context. However, the location information in the conventional works usually depends on a GPS receiver that has limited function, because it cannot localize a person in a building and thus lowers the performance of the user-context awareness. This paper develops a system to solve such problems and to infer a user’s hidden information more accurately using Bayesian network and indoor-location information. Also, this paper presents a new technique for localization in a building using a decision tree and signals for the Wireless LAN because the decision tree has many advantages which outweigh other localization techniques. 相似文献
