‘Digital’ telecommunication flows and ‘physical’ corporeal flows provide researchers with comprehensive indicators of the economic interactions between cities. However, previous research drawing on telecommunication-based measures of inter-urban connectivity has been hampered by inadequate conceptualizations and data. This paper draws on this observation to devise a new approach for measuring inter-urban connectivity based on a city’s insertion in Internet backbone networks. The straightforward example of air transport flows is thereby used to outline this approach. To investigate telecommunication and air passenger flows, use is made of European statistics on Internet eXchange Points and the MIDT airline database respectively. The approach is illustrated through a systematic comparison of the position of European cities in both types of networks. It is found that European cities assume largely similar hierarchical levels in terms of digital and physical information flows, albeit that the digital connectivity of centrally located European cities is often somewhat higher than that of peripheral cities with a similar levels of physical connectivity.  相似文献

This paper describes the evolution of the mobile Internet in terms of three concepts: the startup problem, standard setting, and mental models. Products in which there is little or no value to the first users due to the existence of strong direct (e.g., telephone) or indirect (complementary products) network effects face a large startup problem. This paper divides the startup problem for the mobile Internet into two stages. Japanese and later other service providers solved the first startup problem with entertainment content that was supported by a micro-payment system (service providers collect and pass on content fees to content providers) and custom phones that displayed this content in a consistent manner.  相似文献

It is often assumed that the Internet would threaten the survival of authoritarian regimes. Accordingly, most country-comparative studies have identified a democracy advantage in Internet diffusion. This paper revisits these technology-centric assumptions by conceptualizing the adoption of the Internet as a dynamic phenomenon with multiple phases that unfold differently depending on the political system. It is argued theoretically, that initially, the Internet diffuses faster in democracies because of inherent innovation advantages. However, authoritarian regimes adopt the Internet at comparable rates when the economic benefits of the technology outweigh the democratization risks. Yearly cross-sectional regressions for the years 1996–2013 show that the relationship between regime type and Internet diffusion varies temporally as authoritarian regimes have caught up considerably. Since 2013, there are no significant differences between democracies and authoritarian regimes anymore and monarchies even outperform democracies.  相似文献

As Internet applications evolve and require wider and more stable bandwidth, Internet service providers (ISPs) try to maximize their profit by controlling application service providers (ASPs); this has caused a network neutrality debate. This article categorizes ASPs into four groups by bandwidth-usage attributes and latency sensitivity. By estimating the efficiency of these groups, their efficiency differences are estimated, indicating evidence of discrimination of ISPs when network neutrality is not maintained. Meta-frontier analysis is used to compare efficiencies across companies using different production function technologies. Finally, a Tobit regression model is used to determine which variables explain the difference of efficiencies. The estimation result indicates that the discrimination of ISPs against ASPs is not significant enough to decrease the efficiency of any application group.  相似文献

China's financial industries started the process of marketization only two decades ago, but by 2017 its financial technology or fin-tech sector had taken half of the global market. The exponential diffusion of information and communication technologies (ICTs) in Chinese financial contexts have generated new organizational structures and socio-political relations that have the capacity to change China's position in the world economy. Drawing upon the sociological concept of institutionalization, this paper examines how the Chinese state has integrated ICT diffusion in its formal policies and its informal rules in China's financial development since 1991. Further, it addresses the political and socio-economic consequences of these developments. Based on the analyses of government documents and sources, trade journals, and statistic data from business databases, this paper divides the Chinese institutionalization of financial technologies into three stages and identifies the primary actors and paradigms for ICT diffusions in each stage. ICT diffusion has been constitutive but also disruptive to the existing financial policies, instrumental to the commercialization of state-owned banks, and has gradually transformed into a set of formal and informal rules accepted by a network of professionals, corporations, and government agencies. The institutionalization of ICT diffusion has engendered the continuous adjustment of financial policies and propelled innovations in China's financial economy.  相似文献

Wheat is the oldest and most important of the cereal grains in world food supply. In the last two decades the role of wheat in the world food economy has increased substantially, especially in the developing world. This article describes and analyses the role of wheat and highlights and interprets changes that have occurred in the last two decades of rapid change. The authors analyse, in turn, trends in production, consumption, trade and prices with special emphasis on the developing countries.1 Finally, the authors speculate on how these trends are likely to be effected by future events.  相似文献

The paper examines the main economic and institutional incentives which have driven major OECD food retailers in their use of private voluntary standards and discusses their growing role in shaping the agri-food system. It is based on interviews with quality and safety directors of major OECD retailers and a brief survey of retailers’ actual buyer practices. Though not all retailers are included, these firms account for over 70% of retail food sales in OECD countries. We find that the growing voice of civil society, changing legal and institutional frameworks, increased market concentration and buying power as well as their integration with financial markets has provided the setting for development of private standards. While food safety and quality standards are seen as key to maintaining and improving reputation as well as against legal liabilities, additional standards such as labour, environmental and animal welfare are also gaining ground as strategies for customer loyalty and market shares. The grass-roots retailer move in the harmonization of food safety standards is seen as an initial step towards a global approach to managing the food system, with harmonization of other standards likely in the future. Given their buyer power, these developments can be viewed as a way of governing the food system and will be important for both OECD and non-OECD food and agricultural sector evolution in the coming years.  相似文献

Internet censorship and control have been commonplace in Tunisia since the Internet became available to then public in 1996. It was not until the last days of the Jasmine revolution in January 2011 that the Tunisian government shut down the censorship regime, raising numerous questions about Internet censorship in Tunisia. This article will look at how former Tunisian president Ben Ali was able to shut down the Internet censorship regime within a matter of hours. In order to answer this question, it looks at the history of the Tunisian Internet and its Internet censorship regime, before analysing Internet architecture, Internet institutions, functional differentiation between elements of the regime and the role of international technology markets. Each of these factors contributes to the overall censorship regime and helps understand how former President Ben Ali was able to shutdown Internet censorship within a matter of hours. In conclusion, tracing the genesis of the Tunisian censorship regime may contribute to understanding the role of institutional, architectural and market-based factors in enabling other censorship regimes across the world.  相似文献

New product development requires a long and detailed process with numerous activities such as product line planning, strategy development, concept generation and screening, business analysis, development, testing and validation, manufacturing development and commercialization. Furthermore, each of these activities has its own unique requirements, some requiring information collection from the market, whereas others requiring the collaboration of different people who are involved in the new product development activities. This paper investigates the Internet's role in these activities and develops research propositions. In addition, it discusses how the impact of the Internet might change based on different products and different organizational conditions.  相似文献

Past research has extensively investigated the role of the Internet in enhancing the effectiveness and efficiency of the new product development (NPD) process. Although the process implications of the use of the Internet in NPD have received considerable attention in the literature, very little is written about the Internet's performance implications in NPD. Recognizing the importance of new product success and the growing trends in the use of the Internet in NPD, this paper investigates the role of the Internet in new product performance. Building on previous studies, this article develops theoretical explanations for the impacts of the use of the Internet in NPD on new product success and presents testable research propositions. It also outlines relevant conditions that might moderate the strength of the impacts.  相似文献

With the emergence of Internet based communication and collaboration, new forms of production have surfaced that are based on openness and non-proprietary resources. The paper analyses the role of open source and peer production elements in the response to the attacks on Estonian Internet services in 2007 and the Conficker botnet in 2008/2009.  相似文献

A central part of the innovation process concerns the way firms go about organizing search for new ideas that have commercial potential. New models of innovation have suggested that many innovative firms have changed the way they search for new ideas, adopting open search strategies that involve the use of a wide range of external actors and sources to help them achieve and sustain innovation. Using a large‐scale sample of industrial firms, this paper links search strategy to innovative performance, finding that searching widely and deeply is curvilinearly (taking an inverted U‐shape) related to performance.

This paper examines the hypothesis that ICT penetration has positive effects on economic growth. On theoretical grounds, this paper discusses three channels through which ICT penetration can affect growth: (i) fostering technology diffusion and innovation; (ii) enhancing the quality of decision-making by firms and households; and (iii) increasing demand and reducing production costs, which together raises the output level. This paper conducts three empirical exercises to provide a comprehensive documentation of the role of ICT as a source of growth in the 1996-2005 period. The first exercise shows that growth in 1996-2005 improved relative to the previous two decades and experienced a very significant structural change. The second exercise uses the traditional cross-country regression method to identify a strong association between ICT penetration and growth during 1996-2005, controlling for other potential growth drivers and country-fixed effects. The third exercise uses the system Generalized Method of Moment (GMM) for dynamic panel data analysis to tease out the causal link between ICT penetration and growth. This analysis also shows that, for the average country, the marginal effect of the penetration of internet users was larger than that of mobile phones, which in turn is larger than that of personal computers. The marginal effect of ICT penetration, however, lessens as the penetration increases. This paper points out several policy implications drawn from its analyses and findings.  相似文献

A review of 356 publications addressing internationalisation aspects of the telecommunications services industry (TSI) shows a growing body of contributions, mainly covering research themes like settlement and regulation policy, strategic alliances and incumbents’ reactions to deregulation as well as opening of markets in-depth until recently. Wireline telephony TSI has been the dominant segment in most contributions, while the mobile or broadband Internet segments only featured in more recent work. Segment characteristics like non-uniform barriers to entry, different reasons for alliances and non-uniform levels of internationalisation differentiate these TSI segments pose a number of additional questions concerning telecom firms’ internationalisation strategy and success promising for future research.  相似文献
