    As one of the most widely accepted adoption models in information systems research, the technology acceptance model (TAM) focuses exclusively on cognition-oriented constructs such as perceived usefulness and perceived ease of use. This perspective may have limited the explanatory power of TAM when it is utilized in studying consumers' adoption intentions of online shopping. Based on the contrasts between e-commerce systems and traditional workplace information systems as well as empirical findings from a variety of recent e-commerce research works, this paper analyzes an extended model which integrates three additional constructs: trust, social presence, and perceived enjoyment. The interrelationship between these constructs is also explained. Empirical validations of this extended model are expected in future research. View full abstract»

    The technology acceptance model (TAM) is an important tool in information technology research. Many scholars have applied the classical TAM to various research domains. However, the relationships between variables in these TAM models are not strongly desired. Thirty-four articles selected from international journals were analyzed to show that most of the relationships in the classical TAM are significant, but the stabilities of these relationships differ. The significant positive relationships between perceived ease of use and its independent variables are more stable than the others. Various factors can strengthen or weaken these relationships.

    Lack of trust is one of the most important obstructions to consumers' acceptance of e-commerce. With the increase of companies going online from offline, trust transfer has been found between offline presence and online presence. By applying the entitativity theories, this study empirically tested the trust transference from offline presence to online presence and addressed the underlying reasons through a questionnaire investigation on the customers of Lianhua supermarkets and Lianhua OK online supermarkets. Process integration was used as a useful means to promote this transfer process. For a click-and-mortar company such as Lianhua Group, its established offline trust is one of the major sources contributing to its initial online trust building. The results from this study suggest a new way to enhance e-commerce acceptance. View full abstract»

    Electronic commerce is becoming increasingly important in business, but lack of intention to purchase has become a main barrier in the development of electronic commerce. Thus, effective measures are needed to promote consumers' intentions to purchase in online consumer to consumer (C2C) stores. This paper postulates that five factors, the perceived ease of use of the website, perceived usefulness of the website, vendor competence, introduction and recommendations of third parties, and vendors' attitude toward customers, influence consumers' intentions to purchase in online C2C stores and this intention directly leads to their action to purchase from online C2C stores. The structural equation modeling (SEM) method was used to analyze empirical data, supporting these hypotheses except for the effect of vendor competence. View full abstract»

    Publication Year: 2008 , Page(s): 306 - 311
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (215 KB)  

    Two classical theories, the technology acceptance model (TAM) and the innovation diffusion theory (lOT), were integrated into a model for analyzing individual information technology (IT) adoption behavior. In this IDT-TAM framework, the perceived characteristics of innovation are categorized as subjective evaluation, objective conditions, and interaction factors. The cognitive mechanisms that drive user IT acceptance are analyzed based on the patterns through which these characteristics influence individual user IT adoption behavior. The model was tested using an empirical survey regarding the adoption and use of e-mail in China. Results from a structural equation model analysis illustrate that the model provides meaningful insights for understanding, explaining, and predicting the IT adoption behavior of Chinese users.

    The increased use of information technologies has led to more research on information technology/information system (IT/IS) adoption and decision-making behavior in small businesses to improve information utilization. This paper presents an extensive review of the literature on IT/IS adoption to identify the key factors affecting small businesses based on comparison analysis. The review identifies the current interest in the adoption of Internet based IT and points out that the factors affecting different stages of the business lifecycle and research variables should be selected in terms of the different technology types. Especially, the review emphasizes the characteristics of external openings on the network in the research on e-commerce adoption. Future studies should focus on IT/IS adoption and implementation in small and medium-sized businesses during the development of small and medium-sized industrial clusters and specialty towns.

    Conflicting results from previous research relating information technology (IT) investments and firm performance suggest that there is no direct relationship between IT investments and firm performance. The resource-based view (RBV) of the firm is introduced as a research tool to examine how IT resources and capabilities affect firm performance. A theoretical rationale model is then used to investigate the relationship between IT investment and firm performance. The IT capability is assumed to be an important moderator variable rather than a mediator variable linking IT investments to firm performance, while the time period, the firm size, and the industry type, all recognized as factors influencing performance, are treated as control variables. The model and hypotheses are verified by sample data from leading IT firms in China. The data confirms the moderating effect of the IT capability. View full abstract»

    In order to examine the problem of how to improve the use of information technology (IT) in enterprises, this paper makes an exploration from the perspective of organizational absorptive capacity. We propose the concept of IT absorptive capacity from an organizational level. A dynamic process model is developed to further analyze IT absorption. IT absorptive capacity of this process is embodied as six forms: identification, adoption, adaptation, acceptance, infusion, and knowledge management. By means of questionnaire surveys of 76 Chinese enterprises, the main factors that favor or disable the capacity of each stage are discovered. Using the method of system dynamics, a conceptual model of IT absorptive capacity is developed to analyze the action mechanism of the factors in detail. The model indicates that the critical factors are embodied in the aspect of management. Furthermore, it demonstrates that IT absorption is a spiral process, during which IT absorptive capacity evolves dynamically and, consequently, promotes IT use. View full abstract»

    Investigators seek ways to effectively raise the response rate of surveys. Incentives have a great influence on response rate, retention rate, and response quality in traditional surveys. The purpose of this paper is to investigate what kinds of incentives are effective in web-based surveys. This study summarizes the research framework of previous studies on the effect of incentives in web-based surveys to show that material incentives have a significant effect on web-based surveys with prepaid incentives having a moderate influence on raising the response rate. Contingent incentives significantly reduce the response rate. These findings provide guidance for web-based investigations. View full abstract»

    The alignment between information systems (IS) and business strategy along with its implications for perceived IS effectiveness and business performance is an important question, which is rarely studied in China. Based on an empirical study, this paper summarized the significance of IS strategic alignment and its impact on business performance. This study also measured business strategy, information system strategy, and information system strategic alignment, built a conceptual model to describe the relationship between these factors, and investigated their implications for information system performance and business performance. A structural equation model was employed to test the conceptual model. Analyses of data gathered in a survey indicate that information system strategic alignment is a better predictor of business performance than business strategy or information system strategy alone, although business strategy can significantly influence business performance.

    Retailing is an important component of every country's economic system. The current status and developments in the informization of Chinese retail industry were investigated by using questionnaires and interviews to survey 139 retailers throughout China. The investigation shows that Chinese retailers are in the initial informization stage, and can be classified into different types with corresponding informization characteristics. In addition, the survey identified the key problems faced by retailers in the initial stage. Developments in the information technology field were analyzed to identify the key technologies that Chinese retailers should focus on during the informization process. The investigation also shows that the retailers have not arrived at a consensus about information technology adoption, and thus hesitate to use new information technologies, such as the radio frequency identification.

    Web sites are very important and companies can attract customers by promoting various features of the web site. This paper presents an analysis of the relationship between web site functions and firm performance. A research model based on the DeLone and McLean (D&M) model and customer service life cycle (CSlC) theory was used to investigate the impact of web site functions on e-business success. The research model considers web site functions, web site use, customer satisfaction, and firm performance. According to the CSlC theory, there are three stages in a customer service life cycle. Therefore, the web site functions are divided into three stages: requirements, acquisition, and ownership. The functions in each stage serve to encourage usage and thus, enhance customer satisfaction and firm performance. The theoretical model and hypotheses were tested using data collected from 72 wholesale and retail firms in China using the partial least squares (PLS) method. The results suggest that web site functions in the acquisition stage have the strongest impact on web site use and that the improvement of customer satisfaction can significantly increase firm performance.

    Web services use an emerging service-oriented architecture for distributed computing. Many organizations are either in the process of adopting web services technology or evaluating this option for incorporation into their enterprise information architectures. Implementation of this new technology requires careful assessment of the needs and capabilities of an organization to formulate adoption strategies. This paper presents a methodology for web services adoption based on technology adoption theory and business process analyses. The methodology suggests that strategies, business areas, and functions within an organization should be considered based on the existing organizational information technology status during the process of adopting web services to support the business needs and requirements.
