Customer acceptance of IPTV service quality 总被引：1，自引：0，他引：1

The purpose of this article is to provide insights into the effects of Internet Protocol Television (IPTV) service quality and reveal mediation effects in the process of forming the repurchase intention. This study incorporates additional theoretical construct, perceived enjoyment, to reflect IPTV characteristics using extended technology acceptance model (TAM). This study empirically investigated a research model and conducted a survey of IPTV service users. The results of this study are as follows. First, IPTV service quality is summarized as design, security, and customer service, which is supported by second-order factor analysis. Service quality had an influence on perceived usefulness, perceived ease of use, and perceived enjoyment. Second, perceived ease of use had a significant effect on perceived enjoyment, and perceived usefulness also had an effect on repurchase intention. Third, attitude, trust, and satisfaction had a positive effect on repurchase intention. To reveal the impact on repurchase intention of the IPTV service quality, this study proposes customer acceptance on IPTV service based on a modified TAM. 相似文献

This paper examines empirically the factors that affect the adoption of Internet banking by Tunisian bank customers. As base model, we use the technology acceptance model (TAM) and theory of planned behavior (TPB). The model employs security and privacy, self efficacy, government support, and technology support, in addition to perceived usefulness, perceived ease of use, attitude, social norm, perceived behavior control and intention to use Internet banking. Structural equation modeling is employed to examine the inter-correlations among the proposed constructs. A survey involving a total of 284 respondents is conducted and confirmatory factor analysis was used to determine the measurement efficacies. Theoretically, this study confirms the applicability of the TAM model and TPB in predicting Internet banking adoption by Tunisian bank customers. The results allow banks' decision makers to develop strategies that can encourage the adoption of Internet banking. Banks should improve the security and privacy to protect consumers' personal and financial information, which will increase the trust of users. Government should also play a role to support bank industry by having a clear and solid law on this will ensure that customers are more confident for using Internet banking, ensuring a better Internet infrastructure and helps them to encourage users to use Internet banking. Lastly, Tunisian Banks should focus on those clients who already have a home PC, access Internet and more educated and younger since they are the most likely to adopt Internet banking. 相似文献

作为一项为企业带来巨大价值的信息技术,RFID在我国企业中的采纳受哪些因素影响是一个重要的研究问题。本文以技术接受模型为基础,结合RFID的特征,建立了包含技术、组织和制度与外部环境三方面因素的企业RFID技术采纳模型。实证研究发现:我国目前企业RFID的应用水平还很低;有用性认知、易用性认知、强制性压力、相互信任和客户对隐私的关注都对企业采纳RFID的行为意向产生了显著影响;同时,易用性认知和高级管理层的支持还通过有用性认知对行为意向产生了间接影响;然而,高级管理层的支持、信息系统基础设施、正规化压力和模仿竞争力对企业采纳RFID的行为意向影响不显著。 相似文献

This study enhances the existing literature on online trust by integrating the consumers’ product evaluations model and technology adoption model in e-commerce environments. In this study, we investigate how perceived value influences the perceptions of online trust among online buyers and their willingness to repurchase from the same website. This study proposes a research model that compares the relative importance of perceived value and online trust to perceived usefulness in influencing consumers’ repurchase intention. The proposed model is tested using data collected from online consumers of e-commerce. The findings show that although trust and e-commerce adoption components are critical in influencing repurchase intention, product evaluation factors are also important in determining repurchase intention. Perceived quality is influenced by the perceptions of competitive price and website reputation, which in turn influences perceived value; and perceived value, website reputation, and perceived risk influence online trust, which in turn influence repurchase intention. The findings also indicate that the effect of perceived usefulness on repurchase intention is not significant whereas perceived value and online trust are the major determinants of repurchase intention. Major theoretical contributions and practical implications are discussed. 相似文献

An empirical investigation of mobile banking adoption: The effect of innovation attributes and knowledge-based trust 总被引：5，自引：0，他引：5

Rapid advances in mobile technologies and devices have made mobile banking increasingly important in mobile commerce and financial services. Using innovation diffusion theory and knowledge-based trust literature, this study develops a research model to examine the effect of innovation attributes (perceived relative advantage, ease of use and compatibility) and knowledge-based trust (perceived competence, benevolence and integrity) on attitude and behavioral intention about adopting (or continuing to use) mobile banking across potential and repeat customers. Based on a survey of 368 participants (177 for potential customers and 191 for repeat customers), this study uses a structural equation modeling approach to investigate the research model. The results indicate that perceived relative advantage, ease of use, compatibility, competence and integrity significantly influence attitude, which in turn lead to behavioral intention to adopt (or continue-to-use) mobile banking. Additionally, by using multi-group analysis with t-statistics, the results found that the antecedents of attitude toward mobile banking differ between potential and repeat customers. The implications for research and practice and future research directions are discussed. 相似文献

随着云计算的不断发展,云企业信息系统(EIS)显示出其优势,愈来愈多企业愿意考虑从传统EIS转换到云EIS系统。然而,却很少研究探讨企业在EIS的转换议题,本研究整合信息系统成功模型和技术接受模型,发展一个多理论框架去探索企业向云ERP转换的意愿。我们从企业管理者收集了199份调查问卷,通过结构方程模型验证本研究模型与假设,结果发现有用性和易用性是影响转换意愿重要因素,易用性、信息质量和系统质量则正向影响认知有用性,这些结论,给未来转换意愿研究提供了参考,我们建议云服务供应商应重视系统本身的易用性和有用性,提高系统质量并关注信息质量,以帮助他们提供企业需求的产品,吸引更多企业从传统EIS转换到云EIS。 相似文献
