This paper provides a hedonic price analysis of mobile telephones for the German market, based on data of 302 different handsets from 25 manufacturers over the period from May 1998 to November 2003. By measuring shadow prices for different product characteristics, the authors find that volume, for example, has a negative effect on the price of a mobile handset, while the number of ringtones and the talk time battery life relative to the handset's weight positively affect mobile phone prices. Perhaps somewhat surprisingly, radiation is statistically insignificant. Also handsets have become cheaper over time, and handsets with additional features, such as MMS, MP3 or Bluetooth, command a higher price. In addition, there are positive brand name effects for some brands. According to the estimations presented in this paper the brand name premiums may range from 57 to 172 euro.  相似文献

Emergence of new technological innovations in networks, platforms, and applications has enabled service providers to gain back their massive investment in their infrastructures. However, due to lagging adoption, many service innovations have failed to generate profit. The adoption of different mobile service categories depends on several factors. The current explorative study aims to use Analytic Hierarchy Process (AHP) to identify the most relevant mobile services for consumers and the factors driving the adoption. The results of the AHP analyses indicate that functionality of services is of utmost important for the majority of respondents. The results reveal that basic mobile communication services are the most preferred ones, although several services within different categories are available. The results have important implications for mobile network operators, service and application providers on how to develop and implement specific mobile services. The current study also offers new insights for researchers by showing that AHP is applicable to analyze consumers' preferences.  相似文献

Using Rogers' diffusion of innovation model as the theoretical framework, this study examined the relationships between lifestyle orientations and the adoption of nine Internet-related technologies in Taiwan including IPTV, digital cable, emails, Internet instant messages, Facebook, scanners, notebooks, printers and personal computers. A telephone survey was conducted to collect data, and 506 valid questionnaires were obtained, representing a response rate of 58.6%. The results showed that lifestyle orientations were a powerful predictor for the adoption of information-oriented and entertainment-oriented technologies, but not for the adoption of interpersonally oriented technologies. Furthermore, this study found that while demographics were the most powerful variable that distinguished the adopters from the non-adopters, mass media use was not.  相似文献

This paper aims to specify factors promoting the 3G mobile in Japan. The factors are represented by value-added services such as FeliCa, which enables e-payment, data roaming services, and full music downloads. Panel data from the three main carriers, which occupy over 90% of the Japanese mobile market, is utilized. In order to control network effects as well as the endogeneity of variables, the Arellano–Bond dynamic panel estimation is adopted. As a result, the launch of the iPhone 3G, FeliCa, data roaming, full music downloads, and the flat rate are revealed to have affected the diffusion of the 3G mobile in Japan. The results, reflecting the importance of value-added services, can be applied not only to the next generation mobile development, but also to the promotion of 3G networks in other countries.  相似文献

Despite its growth experience, Ireland still lags behind in international league tables on broadband adoption and within Ireland great disparities exist between central and peripheral regions. This paper explores the context-specific determinants of broadband adoption among Irish small- and medium-sized enterprises (SMEs), attempting to shed some light on the sources of the considerable geographic variation in particular. Drawing from determinants of broadband adoption identified in literature the authors develop a number of plausible hypotheses. Using cross-section data from a ComReg survey of Irish-based SMEs, a logit model of broadband adoption is estimated. Among other factors, a company's industrial sector and other demand proxies are good predictors of broadband adoption. Controlling for other factors, regional ISP market concentration appears to be negatively associated with the probability of broadband adoption. It is argued that, in the absence of more detailed information, statistics on regional-level market structure could be a promising indicator of the supply-side.  相似文献

This study analyses the adoption and use of mobile money (MM) services based on data collected on 1000 households from the Global Findex Survey conducted in 2017 in Cameroon, by the World Bank. More specifically, this study attempts to first profile MM adopters, and then identify the explanatory factors of the different uses of these services. A Probit model is used to highlight the explanatory factors of MM adoption combined with multivariate regressions to identify the determinants of MM service use. Then, estimates of three independent Probits, under the assumption of non-simultaneity of the different uses of MM services are done to test the reliability and robustness of the results. The results reveal that socio-economic factors such as age, level of education, the standard of living and mobile phone ownership differentially affect both the adoption and use of MM services in Cameroon.  相似文献

This paper examines the diffusion pattern of mobile telephony in Colombia. The empirical modelling approach adopted in the paper starts off by choosing between the two functional forms that are most frequently used in the literature, namely the Gompertz and the Logistic models. After applying a formal statistical test to choose the preferred functional form, the evidence suggests that the pattern of diffusion can be best characterised as following a Logistic model. The findings also suggest that despite the fact that in recent years the rate of growth of mobile phone subscribers has started to slow down, there still appears to be room for further expansion as the saturation level is expected to be reached in 2013. The estimated saturation level is consistent with some individuals possessing more than one mobile device.  相似文献

Mobile telephony penetration is a major indicator of mobile telephony diffusion. Taiwan had a mobile telephony penetration of 108% in 2002, ranking first in the world. This study analyzes this accelerated diffusion in terms of growth model and determinants of the diffusion rate. To eliminate the inherent uncertainty associated with choosing the optimal growth model, this study compares the performance of three conventional models, namely Gompertz, Logistic and Bass, to identify the most appropriate model, and to distinguish the forces driving the diffusion rate. Empirical results indicate that the most appropriate model is the Logistic model. Network externalities, which this study shows to be the same as the imitation effect in the Bass model, explain the superiority of the Logistic model. Moreover, market competition, which markedly reduces service prices, is identified as a primary driver of the diffusion rate of mobile telephony in Taiwan. Economic conditions, technological innovation and number of operators are insignificant factors. Finally, mobile telephony is a substitute for fixed-line telephony in Taiwan.  相似文献

In order to define the mobile network operators' strategies of building value network in the 3G era, this paper applies the ecosystem principles to the mobile industry through a China Mobile case study. Based on an analytical framework of such principles, this paper reviews China Mobile's ecosystem, and identifies its success factors and problems. The results indicate that a complete ecosystem, where mobile network operators collaborate closely with value-added service providers, content/application providers, equipment and device manufacturers, and other involved organizations, can promote the development of mobile data services substantially. Therefore, mobile network operators should play a central role in the ecosystem by managing the entire value-chain and setting up proper value-sharing mechanisms. However, while doing so, problems may arise because of regulatory issues and information asymmetry. High-value common assets, a centralized management system, partner selection schemes and continuous innovations are important success factors.  相似文献

In several developing countries in Sub-Saharan Africa, accessibility to digital financial services is increasing because of the development of mobile money services. People previously excluded from the financial system have started to have access to financial services such as receiving and sending remittances, saving, and borrowing. This study examines the effect of network accessibility on the use of mobile money in six developing countries (Bangladesh, Kenya, Nigeria, Pakistan, Tanzania, and Uganda) using GPS information on each household and mobile phone network coverage maps. We find that among these six countries, network accessibility is associated with the use of mobile money in a robust way only in Pakistan and Tanzania. In those two countries, when a household location becomes 10 km closer to the center of the area with multiple mobile networks, the probability of using mobile money increases by 10 percent. In the other countries, we did not find a robust relationship between the use of mobile money and network accessibility. This suggests that increasing network accessibility may not be an efficient method for increasing mobile money adoption in certain countries. The fact that mobile money use rates differ between Tanzania and Pakistan also suggests that the effect of mobile networks is unrelated to the overall level of mobile money adoption.  相似文献

When it comes to the analysis of the intrinsic mechanism of market behaviors and hence competition development and regulatory imperatives in the Chinese telecommunications industry, currently there is no consistent pattern offered in the literature. In China's emergent 3G/4G era, market behaviors can be affected by various institutional factors, along with various forms of informal forces, which may translate into different implications for competition regulation. Based on extensive archival research and interview, this current study aims to bridge the gap by following an interpretive approach. An input–output model was substantiated for pattern-matching in the Chinese context base on the postulation of a series of propositions and hence Industry-Gray-Box. Accordingly, two categories of market behaviors, that is, market-driven vs. institutions-driven, were arguably delineated as being underpinning the competition development. Policy implications and future reform imperatives were discussed. This study may advance knowledge in terms of: (1) the establishment of a relatively consistent pattern for mapping the landscape of China's communications industry; (2) the substantiation of the inner working mechanism of China's SOE system in the telecommunications sector; and (3) original first attempt in identifying different roles of telecom SOEs and the governing forces that affect them. The paper also offers extensive and cohesive insights on China's formal and informal institutional environment in general and for telecommunications in particular. Measurements developed in this study may serve as basis for future study.  相似文献

B2B transaction is a rapid growth section within e-commerce. However, despite the increase in the number of B2B transactions, only a few e-marketplaces have successfully attracted a large number of buyers and sellers. The purpose of this study is to investigate the underpinning forces that influence the organizational decision to adopt e-marketplaces and to improve competitiveness through continuous participation in e-marketplaces. This study applies the technology acceptance model, relational embeddedness, and the trust theory to explore the impact of perceived ease of use, perceived usefulness, and relational embeddedness on trust associated with e-marketplace providers. This study further tests the impact of relational embeddedness and trust on relationship performance in the context of e-marketplaces. Based on 284 active buyers and sellers in well-known public e-marketplaces, the empirical findings suggest that perceived ease of use positively influences perceived usefulness of e-marketplaces; perceived ease of use influences user trust of e-marketplaces via perceived usefulness; and relational embeddedness leads to enhanced trust in e-marketplace providers, which subsequently leads to better relationship performance. Both relational embeddedness and trust also influence relationship performance directly. This research reveals the importance of perceived usefulness and relational embeddedness on trust associated with e-marketplace providers.  相似文献

This article aims to explore the interaction between incubators and industrial clusters, which is an important linkage for local development but has not been analyzed in the literature. A model is proposed to describe this interaction. The Industrial Technology Research Institute (ITRI) Incubator within the Hsinchu industrial cluster, the core of Taiwan's technology industries, is considered to be an empirical case. This case is investigated with the proposed model and methods including data analysis, in–depth interviews, manager surveys and stakeholder analysis. It was found that the clustering effect in the Hsinchu industrial cluster is main factor in the ITRI Incubator's development. The ITRI Incubator in turn reinforces the cluster in some aspects as feedback. This result confirms the existence and importance of this interaction in local development. It is recommended that government officials and incubator managers take account of this interaction in operating an incubator program and utilize the proposed model to analyze the incubator's contributions to its industrial cluster.  相似文献

Every student in the Swedish compulsory school system is entitled to information regarding their progress in all school subjects given. In 2008, a mandatory assessment tool, called the individual development plan (IDP) with written assessment, was introduced by the Government. The statutory purpose was to provide teachers with a formative assessment tool to be used mandatory in the follow-up of student’s progress all thru mandatory compulsory school (year 1–9). This study explores the use of the IDP documents in technology education. Authentic documents from different municipalities, different schools and different school years have been studied. In this article findings regarding formal assessment documents and teacher’s formal assessment practice in primary (year 1–6) technology education are presented.  相似文献

Previous studies of development trends in the telecommunications industry have estimated market potential but have seldom integrated analyses of customer preferences and macro-environmental factors (political, economic, social, and technological analyses). In order to more accurately analyze 4G technological trends and market penetration and provide implications for businesses and policymakers, we use conjoint analysis to analyze customers' preferences for telecommunications technology and integrate the results with data from scenario analysis and the Delphi method to address possible scenarios for the development of 2G, 3G, Worldwide Interoperability for Microwave Access (WiMAX), and long-term evolution (LTE) in Taiwan. We then use the innovation diffusion model to forecast the sales volume for these four technologies in Taiwan over the next 10 years. Finally, we provide suggestions for policymaking and strategic actions for 4G stakeholders.  相似文献

Two key issues within the debate around ‘technological sovereignty’ in the European Union are (i) access by countries and firms to enabling and emerging technologies and (ii) how strategic dependencies can be managed in order to preserve competitive positions in global value chains. In this paper, we present and discuss a multidimensional synthetic metric – the Technological Sovereignty Index (TSI) – to provide a global measure that captures the degree of exposure to specific technologies by a country (or group of countries) as well as the vulnerabilities that may be present. The paper validates the TSI by examining the EU's position (until 2021) within the global value chain of advanced 5G mobile communications, focusing on the hardware and component segments. Our findings reveal a weak degree of technological sovereignty due to (i) the shortage of specialized human capital in the EU and (ii) outsourcing trends in the relevant segments; however, untapped capabilities may exist that could partially offset strategic shortcomings.  相似文献

Interactive innovations are distinctive in that their adoption depends on the perceived number of others who have already adopted the innovation. Thus their rate of adoption does not take off in the familiar “S” shape until a critical mass of adopters has been reached. Data on the adoption of 12 telecommunications services by 392 German banks are used to explore our theoretical perspective on the role of the critical mass in the diffusion of interactive innovations. The most important obstacle to the adoption of new telecommunications services by banks is a low degree of diffusion (which suggests the general importance of the critical mass). These obstacles do not differ for the innovators and other adopter categories. The importance of direct network externalities in influencing the rate of diffusion of new telecommunications services should be determined for each new service, rather than assumed to always exists.  相似文献

Given the prevalence of mobile data services and applications (MDSA) such as App Store, it is important to diffuse MDSA and understand user behavior toward it. Recent research on marketing and information systems (IS) has shed light on the habitual use of frequently used IS. This study attempts to develop a research model that clarifies the role of habit in the actual use of MDSA. Considering the unique and specific characteristics of MDSA, this study examines the antecedents of MDSA habit in an effort to elucidate key factors accelerating the development of MDSA habitual use. Data collected from 317 users who had prior experiences with MDSA were empirically tested against the research model using partial least squares (PLS). The analysis results indicate that both continuance intention and habit play an important role in the actual use of MDSA. Moreover, the findings reveal that habit is a more prevalent predictor of actual use compared to conscious intention. It was found that user satisfaction, perceived monetary value, and variety of use serve as the antecedents of MDSA habit. The theoretical and policy implications of the findings are described.  相似文献

Since the inception of telecom reform in 1994, structural reform has been a main thread surrounding the course of the development of China's telecommunications industry. In structuring the 2008 reform and the 2009 3G rollout China's government adopted a relatively balanced approach in the hope of creating level-playing-field in 3G era. Nevertheless, due to the presence of substantial switching costs, substitution effects from the present technology mode, that is, 2.5G, the absence of killer applications, among other technological and institutional factors, China may not have a realistic 3G era before moving toward 4G and beyond. At the bare minimum, currently there is a lacking of either adequate technological-push or demand-pull for a full-scale 3G commercialization—there is no sign that this situation will change in the near term. Triggered by recent initiatives of market convergence between the telecommunications, Internet, and cable, a renewed circle of market, and regulatory reform is probably necessary to cast a sounder industry basis for a timing migration toward the next-generation-networks (NGNs). The timing migration toward 4G (and beyond) may provide a chance for a late-mover nation like China to leapfrog its western counterparts in leading the industry in the era of NGNs. To this end, China is confronted with a challenge in re-examining its industry policy as well as technological strategies for a sustainable development in the era of NGNs. This study offers heuristic analysis and insights on the above issues based on archival documents and interviews. While implications are suggested for China's circumstances, the Chinese experiences may also be considered by other countries and investors when it comes to 3G (and beyond) policies, regulations, deployments, and evolutions.  相似文献
