The substitution of telecommunications for transportation is held to have major potential for increasing energy conservation within the USA, other developed nations, and even developing nations. This article is the first of a two-part re-examination of the substitution hypothesis based on research and experience of the past decade. This part examines the theoretical potential of telecommunications-transportation substitution for energy conservation, and reviews recent research both on public attitudes towards substitution of telecommunications for travel and on the operational experience with substitution experiments in organizations. Part 2, which appears in the June 1982 issue of Telecommunications Policy, examines the major factors which influence whether individuals and institutions will in fact choose telecommunications over travel, and then discusses government policy which could facilitate telecommunications substitution for travel.  相似文献

The authors present an analytical tool developed and applied to plan for the use of telecommunications technology to link a non-physician health care provider in a rural satellite clinic to a central source of medical expertise. The principal result obtained is that narrowband technologies appear nearly two- thirds as effective as broadband technologies in averting patient travel.  相似文献

Part 1 of this article reviewed existing research both on attitudes toward telecommunications substitution for travel and on operational experiments with teleconferencing and telecommuting. Part 2 examines major factors influencing substitution, including government policy. It concludes that government policy can significantly facilitate telecommunications substitution for travel and, indeed, the achievement of any real measure of substitution may depend upon proactive government policy. However, this is an unlikely prospect in the current US national policy environment.  相似文献

This article examines three major changes which have been occuring in the telecommunications market: liberalization, leading to increased competition in services and equipment, the internationalization of the equipment market, and a rapidly changing industrial structure. The interrelationship among the three trends is analyzed, and the authors hypothesize that it is the technological determinants which are driving the changing structure of the industry and its trade patterns and regulatory environment. The instruments of industrial policy are discussed, with examples from several countries. The European Community's policy in telecommunications is explained in some detail.  相似文献

The authors estimate the net-energy intensity of manual and automated offices. Subjective probability distributions have been used to characterize the considerable uncertainty about the value of a number of the coefficients that are required in such calculations. The current generation of automated offices appears to be more energy-intensive than conventional offices. The energy savings made possible by substituting electronic mail for conventional mail is small compared with this difference. The net impact of substitution for travel will, over the next decade, probably represent less than a few percent of the total energy used in all commuting and other business-related travel and could be either positive or negative.  相似文献

The aim of telecommunications policy in the less developed countries should be to contribute to general development goals, but the links between economic development and telecommunications are not clearly understood. The authors suggest a dual approach to this problem. First, this involves the construction of models of demand based on the interaction between regional economic development and telecommunications use. Second, corporate models are required to explore the feasibility of particular supply strategies. The progress of practical work in these areas is described and includes the results of some specific research in Kenya.  相似文献

Indonesia is currently enjoying rapid development in the telecommunications sector despite the economy having been heavily dependent for almost four decades on the two largest sectors: the manufacturing industry and trade. The telecommunications sector has played an important role in stimulating economic growth in the country during the last few years, with an annual growth rate higher than that of other sectors. This contribution is supported to a great extent by the rapid diffusion of telephony, in particular cellular telephony, as the number of subscribers increased from just 2.1 million in 1999 to 170 million in 2011. Previous studies investigating the impact of the telecommunications sector on the economy aggregate the impact of the sectors on Gross Domestic Product (GDP) without further scrutiny of what sources of growth telecommunications has contributed. Hence, an interesting question arises as to whether the achievement of cellular diffusion is also followed by structural change in the telecommunications sector. That said, this study aims to decompose the output of telecommunications into several sources of growth: domestic final demand, export effect, import substitution effect and technological coefficient effect. A particular interest in this study is to compare the source of growth concerning domestic final demand and the technological coefficient effect. The main tool for analysis in this study is the Input–Output (IO) method, while the time series of the investigation covers the period 1975–2008, allowing comparison of structural changes in the telecommunications sector between the pre- and post-cellular eras. The study found that the coefficient multiplier of the telecommunications sector, which was approximately 1.8 during the 1980s, had decreased to only 1.3 by the end of 2008. Consequently, the final demand from the telecommunications sector contributed less to economic output in the late 2000s compared to the impact in the 1980. Moreover, the cellular era that started in the early 2000s also brought about a trend of changes in telecommunications output. While final demand remains very dominant, the technological coefficient effect has diminished as the source of telecommunications output. This finding indicates a lower ability of the telecommunications sector to build an inter-industry relationship with other sectors. A possible explanation for this result is the cellular uses which are much less related to business activities than that of fixed telephony dating back to the 1970s in Indonesia.  相似文献

This article reviews research work on telecommunications and economic development which can be applied to the problems faced in the less favoured regions of Europe. The authors draw on work carried out under the auspices of the Commission of the European Communities into the disadvantages these regions face in telecommunications supply and use, and the benefits which would accrue from investment. The priorities for regional aid and recommended actions for a European programme are also discussed. The authors conclude that the emphasis should be on the provision of advanced business services and the stimulation of demand for those services, in order to encourage economic growth. General network infrastructure digitalization should be left to PTTs to undertake as part of their normal investment programme.  相似文献

Revolutionary technological and institutional changes, introduced since mid-seventies, are drastically altering the quiet functioning of international telecommunications markets, traditionally characterized by a strong multilateral oligopoly. In such multilateral oligopoly firms had little scope and opportunity for any form of international growth. Since the early eighties the scope for international growth of telecommunications carriers is emerging as a critical issue in international telecommunications. The economics of multinational firms and international trade make it possible to assess the role of technology gaps in the modernization process, international telecommunications tariff asymmetries and global outsourcing as the determinants of multinational growth of telecommunications carriers and their international strategies.  相似文献

Twenty years ago, the telecommunications industry was an established regulated monopoly. But improvements in technology and reductions in costs have ripped apart the premises of natural monopoly and the economic rationale for public utility regulation. The authors review past US telecommunications policy and question the assumptions of the current search for a policy for the future. They believe that, for the industry to develop, institutions and restraints need to be removed.  相似文献

Important quantitative and qualitative changes are affecting employment in the telecommunications manufacturing and services industry worldwide, namely the selective downsizing of employment stocks, the reshaping of job contents and employment composition, and the adoption of innovative labour practices. By resorting to micro-data from the archives of the Italian Institute for Social Security, the paper outlines employment dynamics in the Italian telecommunications industry between 1986 and 1995. Most notable changes detected for public telecommunications operators include the acceleration of inter-companies labour flows and the development of an external labour market for higher skilled employees. However, personnel policies to protect the holders of less tradable skills still exist.  相似文献

This paper charts the development of telecommunications in Bhutan. Since the introduction of telecommunications services in 1963 Bhutan has faced many challenges as it has sought to roll out a network that covers the whole population and country. A small population, a mountainous geography, a transitional economy and a unique approach to development—Gross National Happiness—present many challenges that need to be overcome if the telecommunications industry is to develop further. Added to this is the decision of Bhutan to join the outside world through membership of the ITU, APT and WTO that has added liberalisation and privatisation to the challenges faced by Bhutan. This paper identifies two broad policy options that Bhutan could adopt—network expansion nationally or investment concentration towards urban areas. The authors conclude that due to the limited resources available to Bhutan these policies are contradictory and will take the telecommunications industry in quite different directions if adopted.  相似文献

This article reviews recent trends and regulatory prospects relating to telecommunications interception in Australia. The steady expansion of surveillance powers in Australia over the past two decades, particularly at the federal level, is critically evaluated. Drawing comparisons with the United States, the article analyzes the strengths and weaknesses of the existing regulatory system for telecommunications interception, including legal safeguards such as judicial warrants and civil actions for unlawful interception. The authors conclude by sketching a new normative framework for telecommunications interception that repudiates the idea of “balancing” competing interests in favor of a regulatory model that promotes human rights and due process as paramount considerations.  相似文献

The authors examine the development and use of telecommunications technology in the provision of health services and in that context discuss policy formulation relating to technological innovation in health care. In the course of their examination, they consider the nature of the major challenges facing health care delivery that are amenable to responses in telecommunications technology, present selected findings from telemedicine studies in the light of these challenges, and offer a set of policy recommendations.  相似文献

The Canada-US Free Trade Agreement, which came into effect on 1 January 1989, could well prove to be a breakthrough in the liberalization of trade between the two countries. This paper highlights the provisions of the FTA that indirectly or directly affect the telecommunications industry, assesses their possible impact and evaluates their probable importance to different participants in the industry. The authors make many predictions as to the effects of this agreement in terms of both telecommunications equipment and services and foresee greater competition and larger markets.  相似文献

There is currently widespread discussion in the USA of the merits of amending legislation to allow competition in the cable television market, notably from the telecommunications companies. This article explores what economic theory can contribute to this debate, and adduces empirical evidence on the effects of competition in the cable market where it presently exists. The authors conclude that blocking entry into cable, and indeed into telecommunications markets, is likely to be poor policy, and that increased competition would foster the development of an efficient modern broadband network.  相似文献

The article is an extensive review of the literature covering the history of telecommunications, primarily the telephone and telegraph. Much of the history itself is discussed in the process, including the politics of inventions, monopolies and anti-trust pressures, and industry interaction with government. The ignorance of many authors on the actual workings of the telephone is decried, and many sources for gaining an understanding of the technology are indicated.  相似文献

Restrictions on transmission of data across borders are sometimes proposed as means to control abuses such as invasions of privacy. The authors explore the thesis that controls on cross-border data flows are rarely effective in helping to achieve such ends. They argue that the technology of modern telecommunications does not allow easy control over message content; and that there are other, more strategically effective techniques to restrict abuses committed in international electronic transactions.  相似文献

It has been widely asserted that the Group on Basic Telecommunications (GBT) agreement reached in February 1997 is a significant step forward for the cause of global telecommunications liberalization. This article brings together two authors on different sides of the needed debate about the potential impact of the GBT deal. Following a brief introduction, William Drake argues that the GBT deal could, depending on its implementation, have a substantial liberalizing effect not only on specific markets, but also on the broader institutional arrangements of the global telecommunications policy environment. In response, Eli Noam argues that the GBT is useful, but that its significance is being greatly exaggerated, that most policy changes were taking place anyway, and that it could in some cases have the negative effect of slowing down the process of global liberalization.  相似文献

This article assesses the recent diffusion of new telecommunication technologies. Drawing upon an historical framework, the authors find that new technologies face significant barriers to rapid penetration in the home and office. Data on cable television, electronic text services, teleconferencing and alternative video distribution technologies are analysed to highlight the constraints facing the growth of new telecommunications services.  相似文献
