This paper investigates the cointegration and causal relationships between Information and Communication Technology (ICT) and economic output in Australia using data for about five decades. The framework used in this paper is the single-sector aggregate production function, which is the first comprehensive approach of this kind to include ICT and non-ICT capital and other factors to examine long-run Granger causality. The empirical evidence points to a cointegration relationship between ICT capital and output, and implies that ICT capital Granger causes economic output and multifactor productivity, as does non-ICT capital.  相似文献

In this paper we describe our investigation of the role of investment in information technology (IT) on economic output and productivity in Australia over a period of about four decades. The framework used in this paper is the aggregate production function, where IT capital is considered as a separate input of production along with non-IT capital and labour. The empirical results from the study indicate the evidence of robust technical progress in the Australian economy in the 1990s. IT capital had a significant impact on output, labour productivity and technical progress in the 1990s. In recent years, however, the contribution of IT capital on output and labour productivity has slowed down. Regaining the IT capital productivity therefore remains as a key challenge for Australia, especially in the context of greater IT investment in the future.  相似文献

In the primary context of the USA, the authors discuss technological possibilities compatible with present equipment, which offer some limited improvements in audio broadcasting. They then analyse more radical possibilities which may greatly increase the number of audio delivery channels. Anticipating a substantially different audio broadcasting system by the year 2000, the authors outline the challenges presented by the various possibilities to public policy makers.  相似文献

Attention is turning increasingly to the social problems associated with information societies. Most studies conclude that minimizing the side effects (invasion of privacy, information inequity, information control and misuse of information) of information technology is the task of policy makers. By developing models of the US and Japanese information societies, the author argues that no two information societies will be the same since their character will depend on such variables as national ideology, government policy making organizations, information policy, technology, the marketplace, etc.  相似文献

The US television networks, so long the dominant force in US broadcasting, have seen their market shares and profits begin to fall as the new telecommunication services increase their penetration rates and fractionalize the viewing audience. In response to this competitive challenge, the networks have increased their offerings of news, bid high prices to retain the rights to professional sports, and decreased their reliance on theatrical movies. More importantly, the networks have themselves expanded into the new technologies in a number of different areas.  相似文献

Making decisions on strategic investments, such as early stage manufacturing technology (MT), is a complicated task. Early stage technologies are usually costly, and surrounded by uncertainty. The potential benefits are often hard to quantify prior to implementation. Thus, how could managers make good decisions in a high-risk, technically complex business when the information they need to make those decisions comes largely from the project champions who are competing against one another for resources? Traditionally, in this problem domain, decisions are made based upon gut-feeling and past experience, sometimes with the support of some multi-criteria decision-support tools. The criteria evaluation process is very subjective and relies heavily on managers’ experience, knowledge, as well as intuition. Thus, the evaluation approach is often not effectively carried out as there is lack of visibility and traceability in the decision making process. The impact of this scenario is that managers are not confident that resources are being optimised and applied to a mixed portfolio of projects to maximise benefits. This paper proposes a marginal analysis directed branch and bound approach for evaluating and selecting early stage manufacturing technology (MT) projects. A case study is used to demonstrate the application of the proposed approach. Implications of the proposed approach to practitioners and academia are discussed and future research outlined.  相似文献

This study develops and tests a model of information search in complex buying. We incorporate three categories of influences of organizational, personal and situational factors that affect information searching efforts. A sample of 96 of the largest Brazilian firms reported their use of the various influences in the decision to purchase integrated business management systems. Findings show that formalization of the organization is a key driver of information search efforts. Situational characteristics of importance, novelty and bargaining power increased the level of information search. Also, conformity of the purchasing agent and organizational centralization reduce information search efforts among the sampled Brazilian firms.  相似文献

  总被引:1,自引:0,他引:1  
The rate of market and technological changes has accelerated in the last years. This turbulent environment requires new methods and techniques to bring successful new products to the marketplace. Much attention has focused on new development techniques, but little empirical research has been conducted to validate these techniques. In this study, the relationship between popular new development techniques and new product success is examined. Our findings suggest that only a subset of these popular techniques is significantly related with new product success in Spanish firms. The study also identifies the main contributors to new product development (NPD) effectiveness in Spanish firms.  相似文献

Two conceptual approaches [Davis, F. D. (1989). Perceived usefulness, perceived ease of use, and user acceptance of information technology. MIS Quarterly, 13 (3), 319-340; DeLone, W. H., & McLean, E. R. (1992). Information systems success: The quest for the dependent variable. Information Systems Research, 3 (1), 60-95] are unified into a conceptual model that offers a comprehensive explanation of CRM acceptance antecedents and consequences in a sales force setting. Based upon responses from 240 salespersons that utilize a CRM system, the model is tested and explanations are offered for the system's acceptance. Specifically, the most prevailing influence on CRM acceptance comes from CRM perceived usefulness, followed by the setting of accurate expectations regarding system usage, the salesperson innovativeness towards new technological tools, the CRM perceived ease-of-use, and the supervisor encouragement and support. Surprisingly, the model does not adequately explicate salesperson performance. Sales managers are presented with a discussion and implications of the findings.  相似文献

Information acquisition and optimal project management   总被引:1,自引:0,他引:1  
This paper provides a rationale for why an organization often generates a bias in favor of a new project even after learning that its profitability will be certainly below more conventional ones. We analyze a principal–agent model with two alternative projects, one of which is to be chosen by the principal. In our model, the profitability of a project is determined by the cost of implementation. All parties are familiar with one of the projects (the known project), and thus the implementation cost of this project is common knowledge. Information on the other project (the new project), however, must be acquired by the agent. We find that the new project may be chosen in the optimal contract even when it turns out to be more costly to implement than the known project, if acquiring information is costly enough and the realized implementation cost of the new project is below a particular level. We also discuss distortion in the new project's output schedule when it is selected.  相似文献

Studies of the industrial adoption of innovatious have frequently concluded that managerial attitudes are a crucial determinant of adoption behavior. However, these studies have usually offered hypotheses rather than rigorous tests. Equally important, these studies have not specified the characteristics of those managers whose attitudes exert a particularly strong influence on the firm's adoption policy.  相似文献

This paper examines the role of information communication technology in enabling connections to home for work‐related travellers. Although digital connectivity for work‐related tasks are well researched, the use of digital technology for home communication is under‐researched. The study draws on a qualitative study of UK‐based organisations and business travellers to explore how these travellers use ICTs for personal use while ‘on the move’. The findings reveal that organisations are supportive of work‐life balance for employees, but fail to consider specific needs of those whose work takes them away from home. For business travellers, insights are gained into practices around connecting to home and the value of this virtual presence for relationships with family while absent and work‐life balance. The study identifies and discusses practice occurring around three activities; checking in, maintaining relationships with home and sharing experiences.  相似文献

To maximize customer value created by a supply chain system as a whole, one of the key issues in supply chain management is how to have profit and benefit properly shared between partners in an effective manner of the supply chain integration. In this regard, information sharing between partners plays a rather important role in business process and management integration of the supply chain. The paper focuses on analyzing the value created from information sharing by decreasing inventory level and on investigating the collaborative mechanism of providing incentive to retailer by upstream partner via sharing profit gained information sharing in the context of three-echelon supply chain system. The issue of dealing with the interest conflict between the supply chain as a whole and individual partners is addressed based on information sharing analysis by means of cooperative game approach, a graphic model with three-dimensions is developed to depict the possible cooperative solutions of profit allotment between partners, and a problem solving method addressing how the profit allotment between partners can effectively motivate the partners to be cooperative with each other is presented as well.  相似文献

Assessing the regional digital divide across the European Union-27   总被引:1,自引:0,他引:1  
Despite the efforts devoted to the analysis of the digital divide over the last years, the regional evidence on this issue is still scarce. Within this context, the goals of this paper are twofold: (1) measuring the digital divide across the regions of the 27 Member States and within each country and (2) explaining the observed regional disparities. The analysis leads to identify Dutch regions as the Top-10 in ICT, while Greece and Bulgaria occupy the Bottom-10. Therefore, results show that the regional digital divide reflects to some extent the income gap. However, regional policy seems to be having some positive implications for technology adoption. In particular, the rural-versus-urban dimension of the digital gap appears to be less important than it is usually claimed to. Likewise, some evidence is found of the role of cultural and institutional factors in ICT adoption, an issue that has not been previously analyzed at the regional level.  相似文献

This paper investigates linkages between information technology (IT) and firm performance. Although showing recent signs of advance, the existing IT literature still relies heavily on case studies, anecdotes, and consultants’ frameworks, with little solid empirical work or synthesis of findings. This paper examines the IT literature, develops an integrative, resource-based theoretical framework, and presents results from a new empirical study in the retail industry. The findings show that ITs alone have not produced sustainable performance advantages in the retail industry, but that some firms have gained advantages by using ITs to leverage intangible, complementary human and business resources such as flexible culture, strategic planning–IT integration, and supplier relationships. The results support the resource-based approach, and help to explain why some firms outperform others using the same ITs, and why successful IT users often fail to sustain IT-based competitive advantages. © 1997 by John Wiley & Sons, Ltd.  相似文献
