A structural equation modeling of the Internet acceptance in Korea   总被引:1,自引:0,他引:1  
The objective of this study is to develop and test an integrated conceptual model of the Internet acceptance. Based on the two dominant theoretical paradigms – the theory of reasoned action (TRA) and the technology acceptance model (TAM) – we propose a model of the Internet acceptance to investigate the relationship between external variables such as individual differences, task characteristics and management support, and individual acceptance of the Internet. The model is tested using data gathered from 374 end users of the Internet in Korean firms and data analysis is conducted using a structural equation modeling with LISREL. Significant relationships are found between experience and usefulness, between experience and ease of use, and between ease of use and usefulness. Organizational support is found to influence usefulness, ease of use and subjective norm. We also observe that actual usage is not influenced by subjective norm, but significantly influenced by experience, usefulness and ease of use. This result implies that individual acceptance of the Internet is significantly related to external factors such as experience, task characteristics and organizational characteristics rather than beliefs.  相似文献

We conducted a quantitative meta-analysis of previous research on the technology acceptance model (TAM) in an attempt to make well-grounded statements on the role of subjective norm. Furthermore, we compared TAM results by taking into account moderating effects of one individual-related factor (type of respondents), one technology-related factor (type of technology), and one contingent factor (culture). Results indicated a significant influence of subjective norm on perceived usefulness and behavioral intention to use. Moderating effects were found for all three factors. The findings yielded managerial implications for both intra-company and market-based settings.  相似文献

The success of a virtual learning environment (VLE) depends to a considerable extent on student acceptance and use of such an e-learning system. After critically assessing models of technology adoption, including the Technology Acceptance Model (TAM), TAM2, and the Unified Theory of Acceptance and Usage of Technology (UTAUT), we build a conceptual model to explain the differences between individual students in the level of acceptance and use of a VLE. This model extends TAM2 and includes subjective norm, personal innovativeness in the domain of information technology, and computer anxiety. Data were collected from 45 Chinese participants in an Executive MBA program. After performing satisfactory reliability and validity checks, the structural model was tested with the use of PLS. Results indicate that perceived usefulness has a direct effect on VLE use. Perceived ease of use and subjective norm have only indirect effects via perceived usefulness. Both personal innovativeness and computer anxiety have direct effects on perceived ease of use only. Implications are that program managers in education should not only concern themselves with basic system design but also explicitly address individual differences between VLE users.  相似文献

Understanding processes underlying technology adoption or non-adoption is an important research theme often addressed using the technology acceptance model (TAM) approach. The objective of this research was to investigate most influential user experiences in successful and unsuccessful technology adoptions using user experience related concepts and methods in conjunction with the TAM. Participants (N = 76) described their most influential user experiences related to one successful and one unsuccessful technology adoption process and evaluated both experiences using rating scales, including the central TAM related scales and user experience related scales probing emotions, psychological needs, user values, task load, and the impact of technology on the user’s well-being.The results suggested that user experience and technology acceptance related viewpoints can complement each other in order to gain a more holistic understanding of the factors affecting the success or failure of technology adoptions, and the results showed how these variables typically behave in both contexts. The overall valence of user experience was significantly affected by perceived usefulness, the fulfillment of psychological needs, and the salience of negative emotions in the most influential user experiences of successful adoptions, and by perceived usefulness, output quality, and the salience of negative emotions in the unsuccessful adoptions.  相似文献

This study examines the factors that influence employees’ adoption and use of e-learning systems and tests the applicability of the technology acceptance model (TAM) in the organizational context. We examined the relationship of employees’ perceptions of their behavioral intention to use e-learning systems in terms of four determinants (individual, organizational, task characteristics, and subjective norm), to further explore the effects of management and organizational support on the subjective norm. Data were 357 valid questionnaires from four industries in Taiwan. The findings indicate that organizational support and management support significantly affected perceived usefulness and intention to use. Individuals’ experience with computers and computer self-efficacy had significantly positive effects on perceived ease of use. Task equivocality significantly influenced perceived usefulness. Organizational and management supports significantly impacted the subjective norm, perceived usefulness, perceived ease of use, and intention to use. Additionally, the results suggest that external variables that affect perceived usefulness, perceived ease of use, and intention to use, need to be considered as important factors in the process of designing, implementing, and operating e-learning systems. The results provided a more comprehensive insight of individual, organizational, and task characteristics in predicting e-learning acceptance behavior in the organizational contexts, rarely tested in previous studies. By considering these identified factors, practitioners can take corresponding measures to predict or promote organizational employees’ e-learning systems acceptance more effectively and efficiently. Furthermore, by explaining employees’ acceptance behavior, the findings of this research help to develop more user-friendly e-learning systems and provide insight into the best way to promote e-learning systems for employees.  相似文献

Abstract   Computers are increasingly widespread, influencing many aspects of our social and work lives, As we move into a technology-based society, it is important that classroom experiences with computers are made available for all students. The purpose of this study is to examine pre-service teachers' attitudes towards computers. This study extends the technology acceptance model (TAM) framework, with subjective norm and facilitating conditions acting as external variables. Results shows that perceived usefulness, perceived ease of use and subjective norm were significant determinants of pre-service computer attitudes. Facilitating conditions did not influence computer attitude directly but through perceived ease of use. These findings demonstrate that social norm and facilitating conditions are potential variables that may be used to extend the TAM for research on computer attitudes.  相似文献

Social networking websites (SNSs) have become popular among younger adults, but internet-using older adults have not adopted this communication medium nearly as quickly ( and ). This study seeks to understand what factors encourage or discourage older adults from using SNS, like Facebook, to help understand what may be done to ensure both generations have communication media over which they enjoy and feel comfortable communicating. Using the Technology Acceptance Model (TAM;  and ) as a framework, 124 internet-using older adults aged 60–90, completed attitudinal measures of perceived usefulness of SNS, perceived ease of use of websites, social pressures to use SNS, and trust in SNS, as well as behavioral measures of current internet use, SNS use, and intention to use SNS in the future. Regression analyses revealed significant predictors of SNS include perceived usefulness, trust in SNS, and frequency of internet use. Unexpectedly, factors of ease of use and social pressures were not significant predictors. Implications for the TAM and for individuals with an interest in getting older adults to use SNS are discussed.  相似文献

In the past, most studies used the technology acceptance model (TAM) to survey the subjective perception of users in using information technology. The usability test was also used to assess the ease of use of user interfaces. This study introduces a conceptual framework to explore the relationship between user’s beliefs of TAM and usability testing attributes. Usability testing was conducted on an eCampus learning system with a mobile device. TAM data was collected from the participants for analyzing a possible relationship. The findings of this study reveal that TAM results contradict the usability test results in certain areas. The focus of our proposed research model is supported from the causality between perceived ease of use and usability; however, the correlation between perceived usefulness and usability remains unclear.  相似文献

This paper compared two versions of technology acceptance model (TAM) in understanding the determinants of user intention to use wireless technology in the workplace. The first model is derived from original TAM that includes perceived usefulness, perceived ease of use, attitude and behavioral intention, while the alternative model is a parsimonious version in which the attitude was taken out. The results indicated that TAM, either original or parsimonious, is successful in explaining user intention to use wireless technology in organizations. In addition, the parsimonious model showed a better model fit than that of the original model.  相似文献

The purpose of this paper is to discuss how various factors intertwine to affect Chinese older adults’ decisions to adopt the Internet by applying the expanded technology acceptance model (TAM). Perceived usefulness (PU), perceived ease of use (PEU), subjective norm (SN), and facilitating conditions (FC) were four key predictors. Gender and age were included in the proposed model as factors to moderate the effect of two key TAM components (PU and PEU) on adoption behaviors. The results indicate that PU, PEU, and SN were significant predictors of Internet adoption among Chinese older adults, while PU, SN, and FC were significant predictors of Internet use intention. The effect of PEU on Internet use intention was also found to be stronger for older seniors than younger seniors. Implications for future research and practices are discussed.  相似文献

Guided by Davis’ (1986) technology acceptance model (TAM) and Brehm’s (1989) reactance theory, this study sought to explore the determinants of college students’ adoption of mobile-based text alert short message service (SMS). The findings of the study supported the primary argument of the model that individuals’ adoption of text alert SMS for emergency preparedness and response should be largely determined by social psychological factors, such as attitude toward, subjective norm associated with, and perceived intrusiveness of the SMS. In addition, the findings demonstrated that subjective norm of and attitude toward the service prompted individuals’ actual adoption whereas intrusiveness of the service served as a distinctive barrier to the actual adoption behavior. Finally, the findings also showed that the probability of adopting the text alert SMS was not directly increased by perceived ease of use and perceived usefulness of the service, but was indirectly affected by the two antecedents through ones’ attitude toward the use of the SMS. Theoretical and practical implications of the findings are discussed.  相似文献

This paper reported the results of a survey study and provided evidences of empirically testing a model that integrates both technology acceptance model (TAM) and task-technology fit (TTF) model in understanding the determinants of users’ intention to use wireless technology in organizations. Questionnaires were distributed to organizations that bring mobile commerce into practice through the wireless handheld devices. The results indicated that both technology acceptance model and task-technology fit model are robust models by themselves. First, both perceived usefulness and ease of use significantly influence users’ behavior intention to utilize wireless technology. Perceived ease of use has significant effect on perceived usefulness. Second, characteristics of technology and task significantly predict the fit between these two constructs. Significant effect of characteristics of technology on perceived ease of use and usefulness were observed. Finally, significant relationships between TAM and TTF model were also observed. Task-technology fit is a significant direct predictor of technology adoption intention. Overall, users’ intention to adopt wireless technology in organizations was determined directly by fit between characteristics of task and technology as well as users’ perceived ease of use and usefulness.  相似文献

The present study addresses two basic determinants of technology utilization: the attitude towards a certain technology and the performance when using it. According to the technology acceptance model (TAM), perceived ease of use and usefulness are assumed to be strong determinants of the actual and successful utilization of technology. However, the relationship between the acceptance of technical devices and their successful utilization (i.e. performance) is not completely understood. In this study, users’ attitudes towards technology and their performance when interacting with a computer simulated PDA device were examined. Moreover, the moderating role of individual variables like age, gender, subjective technical confidence, and computer expertise in the relationship between technical performance and acceptance was analyzed. The results showed significant associations between performance and TAM factors. However, this interrelation was much stronger for the older group, especially between performance and the ease of use. The factors computer expertise and technical self-confidence played a minor role. Gender effects on technical self-confidence and TAM factors were identified, although they did not affect performance. Future research should focus on training formats for the older age group, which facilitate a successful interaction with technical devices.  相似文献

This study explores the factors influencing the adoption of IPTV, and tests the applicability of the technology acceptance model (TAM) in a new convergent technology. The behavioural constructs from TAM were tested for predicting user acceptance of IPTV. Structural equation modelling was used to analyse data and to design a theoretical model predicting the individual's intention to adopt IPTV. A modified TAM for IPTV proposes that new constructs determine user-perceived usefulness and enjoyment of using IPTV. Although this study confirms the impact of information quality and system quality on consumers' technology experience, it specifically shows that the perceived quality of content and system were found to have a significant effect on users' perceived usefulness and perceived enjoyment. In addition, social influences had a positive effect on the intention to use IPTV. These findings suggest an extension of the TAM model for convergence technologies. This research advances theory and contributes to the foundation for future research aimed at improving the understanding of users' adoption behaviour of convergence technologies. Implications of these findings for practice and research are examined.  相似文献

With their heavy traffic and technological capabilities, social networking sites (SNS) introduced a new means of building and maintaining perceived social capital. This study aims to identify underlying factors and causal relationships that affect behavioral intention to use SNS. For this purpose, this research developed an extended technology acceptance model, incorporating subjective norm and perceived social capital for predicting SNS acceptance and usage. Exploratory correlation and path analyses were conducted to identify the relationships between five constructs: perceived usefulness, perceived ease of use, subjective norm, perceived social capital, and intention to use. The results showed that perceived usefulness and perceived ease of use had robust effects on the user's intention to use SNS. The research findings also demonstrated that subjective norm and perceived social capital were significant predictors of both perceived usefulness and perceived ease of use and therefore should be considered as potential variables for extending the technology acceptance model.  相似文献

Research on elderly people's ICT acceptance and use often relies on the technology acceptance model (TAM) framework, but has been mostly limited to task-oriented uses. This article expands approaches in technology acceptance and use by developing a model to explain entertainment-related uses of new media technology by elderly people. On a theoretical level, we expand the TAM perspective by adding concepts that act as barriers and/or facilitators of technology acceptance, namely technophobia, self-efficacy and previous experience and expertise with technology. We develop an expanded TAM by testing the role of these concepts in two studies on entertainment media technology. In Study 1, we investigate behavioural intention to use 3D cinema among N?=?125 German elderly media users (Age 50+). In Study 2, we focus the actual use of a computer game simulation by N?=?115 German and US elderly media users (Age 50+). Findings in both studies point towards the central role of perceived usefulness, here modelled as enjoyment, as the reason for elderly people's use and acceptance of entertainment media technology. Perceived ease of use is seen as a precondition for enjoyment, particularly for interactive media.  相似文献

Sponsored advertising has generated strong advertising revenues for Facebook in recent years. As sponsored ads are built on an interactive platform that could be seen as invasive to user privacy, the growth of this advertising platform has important implications for consumers, and advertisers alike. As little research is available on consumer response to sponsored advertising as an interactive technology innovation, the current study assesses the effects of user perceptions of privacy risk, intrusiveness concerns and utilities of sponsored advertising on consumer attitudes and purchase intent. Testing a model derived form the technology acceptance model (TAM), the study found that privacy and intrusiveness concerns are both valid antecedent variables to perceived usefulness but not perceived ease of use of sponsored advertising. While both antecedent variables also influence consumer attitudes toward sponsored advertising, only privacy concerns have an impact product purchase intentions. The hypothesized relations between perceived usefulness, ease of use, attitudes and purchase intentions were also validated.  相似文献

Using electronic-reverse auction (e-reverse auction) offers many advantages to companies such as price reduction, decrease in cycle time, standardization, and transparency in purchasing process. Despite its great advantages, some users do not want to use e-reverse auction technology for the procurement of products or services. This study aims to understand factors affecting e-reverse auction usage in companies by integrating three important theories. Key constructs of technology acceptance model (TAM), theory of planned behavior (TPB), and innovation diffusion theory (IDT) are integrated to explain behavioral intention to use and actual use of e-reverse auction. Using LISREL 8.54, data collected from 156 employees working in the procurement department of companies in 40 different countries were used to test the proposed research model. Results indicated that, 76% of employees’ intention to use e-reverse auction is explained by subjective norms, perceived behavioral control, and perceived usefulness. Among them, subjective norms have the strongest effect. Besides, actual use of e-reverse auction is directly predicted by behavioral intention to use. We conclude with managerial implications and recommendations for possible future research.  相似文献
