Purpose – The purpose of this paper is to identify how adoption drivers change before and after key milestones of ICT product adoption (i.e. critical mass point (CMP) (adoption rate 16 percent), market saturation point (MSP) (50 percent) and new generation release point (NGRP)) based on actual subscriber data of the mobile communications industry that represents the ICT market, so that it has implications for the rejuvenation of ICT product adoption that has rarely been addressed in earlier studies. Design/methodology/approach – This study examined the overall characteristics of ICT product diffusion by tracking the actual patterns of US and Korean mobile market subscribers using the Bass diffusion model. Findings – This study found that innovation effects gain influences on ICT product diffusion after CMP, MSP and NGRP; imitators are becoming innovators by repeated rejuvenation experiences; and cultural differences have significant influences on imitators’ ICT product adoption, but not on innovators. Originality/value – These findings imply that rejuvenation enabled by technology innovation is a key success strategy to dominate the ICT market where the number of innovators, who have strong desires for new generation products, is constantly growing.

This study investigates the impact of FDI and trade openness on ICT diffusion in the Asia-Pacific and Middle East regions from 1996-2005. The results indicate that while dissimilarities exist between the economies included in this study in terms of their level of socio-economic and political development, education and the growth of GDP have had a positive impact on ICT diffusion in both regions. However, while FDI has generally had a positive and significant impact on ICT diffusion in Asia-Pacific economies, its impact on Middle Eastern economies has been detrimental. The results of this study also show that trade-openness has had, in general, a positive and significant impact on ICT diffusion.

In this paper, the authors examine if a difference exists in adopting or diffusing information and communication technology (ICT) between developing and newly developed countries. To analyze the problem, the authors use the Unified Theory of Acceptance and Use of Technology (UTAUT) suggested by Venkatesh et al. (2003), which consists of effort expectancy, performance expectancy, and social influence. The authors also use innovation diffusion functions, made up of introduction, growth, maturity, and decline phases. The authors researched how these factors affect the adoption in the three phases. The authors surveyed cellular phone adopters in Thailand and South Korea for 15 years from 1989 to 2003. Thailand and South Korea each represent developing and newly developed countries, respectively. For the data analysis, survival analysis is used, because it can explain the characteristics of the potential adopters or non-adopters. They found that the ICT diffusion patterns, as well as the ICT diffusion factors, of the two countries are different. Therefore, the results of the authors’ research can be used to build a strategy to reduce the digital divide gaps among countries.

Purpose Based on data collected over a 15 year period (2000–2015) for 89 countries selected across nine geopolitical regions of the world, the purpose of this paper is to explore the role of economic development and the Hofstede index of national cultures in influencing level of government effectiveness and ICT diffusion; as well as the impact of ICT diffusion on government effectiveness. The level of economic development and a country’s ranking on the E-government index were found significant in explaining ICT diffusion and level of government effectiveness, respectively. But the findings also indicate that only the cultural factors such as Indulgence and long-term orientation (LTO) were quite significant in explaining level of government of effectiveness and ICT diffusion, respectively. The findings conclude that while some cultural factors may provide partial explanations for a country’s level of government effectiveness or ICT diffusion, but for other cultural elements, the path of influence is still unclear and at best debatable. Hence, in light of the growing emphasis placed on it in the literature, the effect of culture is limited and may have been overstated. ICT diffusion, while a necessary tool for administrative efficiency, is only but one piece of a larger puzzle and should be developed in consideration of and in the context of a broader framework of economic development, institutional design and behavioral practices. Design/methodology/approach This study examines how existing ICT diffusion and infrastructures among a set of 89 countries spread across nine world geopolitical zones has been able to improve their government effectiveness – as measured by their relative scores or rankings on the global “government effectiveness index” over a 15 year period (2000–2015); and also how specific cultural factors may influence the level of ICT diffusion. Drawing data from the United Nations e-Government knowledge database, the United Nations Development Program, the GlobalEconomy.com, as well as other socio-demographic sources, I examine key and associated indicators that influence information technology diffusion and its contributory effects on level of government effectiveness; as well as the impact of national cultures on ICT diffusion. Findings Overall, the finding from this analysis point to the fact that only two of the Hofstede national culture variables were significant (LTO and Indulgence). The other four national culture variables (Power Distance, Individualism, Masculinity/Femininity and Uncertainty Avoidance) were not. Indulgence has a negative effect on level of government effectiveness, while LTO has a positive effect on ICT diffusion. The other culture variables were not significant in any of the regression models, but they seem to congregate much closer to or around the mean. Originality/value This is the only work of its kind that has utilized the seven Hofstede indicators to test for the relationship between culture and technology over a long period of 15 years.

L’objectif de ce papier est d’analyser le rôle de la diffusion des TIC dans l’analyse de la relation entre le développement financier et la croissance économique dans les pays de l’UEMOA en mettant un accent particulier sur leurs interactions. A partir d’un échantillon de 7 pays de cette zone, sur la période 1997 - 2019, et suite à l’utilisation d’une approche Pooled Mean Group (PMG) sur données de panels, les résultats montrent qu’à long terme, l’effet direct du développement financier sur la croissance économique est significativement négatif dans les pays de l’UEMOA. Secundo, la diffusion des TIC (mobile et l’Internet) a un effet positif et significatif sur la croissance économique. Enfin, l’interaction entre développement financier et la diffusion des TIC est significativement positif, prouvant ainsi que les pays de l’UEMOA ne peuvent bénéficier du développement financier qu’une fois qu’un seuil de diffusion des TIC atteint. Ce seuil de diffusion des TIC est respectivement de 168,7% et 38,1% pour le mobile et l’Internet. The objective of this paper is to analyze the role of ICT diffusion in the analysis of the relationship between financial development and economic growth in WAEMU countries with particular emphasis on their interactions. From a sample of 7 countries in this area, over the period 1997 - 2019, and following the use of a Pooled Mean Group (PMG) method on panel data, the results show that in the long term, the direct effect of financial development on economic growth is significantly negative in WAEMU countries. Secondly, ICT diffusion (mobile and Internet) has a positive and significant effect on economic growth. Finally, the interaction between financial development and ICT diffusion is significantly positive, thus proving that WAEMU countries can only benefit from financial development once a threshold of ICT diffusion reached. This ICT diffusion threshold is respectively 168.7% and 38.1% for mobile and Internet.

This study evaluates the influence of Information and Communication Technologies (ICT) investment and diffusion on Rwanda's economic growth. At the level we recommend, ICT imports greatly improve intermediate inputs to capital goods, resulting in increased economic growth. We use the most recent available data on technical innovation and investment for our empirical study, which spans the years 2005Q1 to 2020Q4. The results of regression analysis show that ICT development has little effect on Rwanda's economic growth. However, we notice a patchwork of information on ICT investment. We utilize ICT goods exports and imports as a proxy for ICT investment, based on previous research. Surprisingly, ICT goods exports have had no impact on Rwanda's economic growth. We do notice, however, that a 1% increase in ICT goods imports boosts economic growth by 3.9 percent. At this level, ICT goods import greatly boost the intermediate input to capital goods, resulting in increased economic growth. As a result, officials should ensure that ICT goods imports should be prioritized through supporting ICT investment to boost economic growth.

Debate regarding the impact of information and communication technology (ICT) on health outcomes has prompted researchers to conduct analyses across many parts of the globe, yet, still little is known about the ICT impact in the African continent. Using a robust multivariate approach, this study examined system-wide impact of ICT diffusion on multiple health outcomes for HIV and tuberculosis among sovereign countries of Africa. This study utilized longitudinal panel data from the World Bank and International Telecommunication Union databases between 2000 and 2016. We relied on a robust linear dynamic panel model to incorporate lagged time variables to estimate the relationships between ICT infrastructure (mobile phone use, internet access, and fixed-telephone subscriptions) and HIV and tuberculosis outcomes. Econometric analyses found that the coefficients of the aggregate ICT variables were all negative (except for fixed telephones) for tuberculosis health measures and HIV prevalence, and positive for access to antiretroviral therapy. The diffusion of mobile phones and internet was associated with decreased incidence of tuberculosis, HIV prevalence, and tuberculosis mortality rates. However, increased diffusion of these three ICT tools was associated with increased access to antiretroviral therapy. Thus, African governments should identify investment strategies for adopting and implementing ICT to improve population health outcomes.

There can not be two opinions on the importance of Information and Communication Technology (ICT) for economic development. However, real disparities exist in access to and use of ICT across countries. The digital divide is a complicated matter of varying levels of access, basic usage, and applications of ICT among countries and peoples. Using the Gompertz Technology Diffusion model, this paper attempts to measure the contribution of factors such as affordability, knowledge, infrastructure, human capital, trade openness, and economic and social environment in the technology diffusion process, specially in the case of information-poor countries.

In this paper, the authors use a mixed methods study, including a survey and follow up interviews, to investigate the concerns that elementary educators in a school district in British Columbia have regarding the diffusion and integration of Information and Communication Technologies (ICT) in their teaching. The research participants identified four major categories of concerns: the philosophy and pedagogy of ICT integration; accessibility of ICT (including software, hardware and resource personnel); infrastructure technical support; and educational integration of ICT in their teaching. Based on the research findings, the authors propose appropriate intervention methods to address these concerns, including targeted professional development, technical and educational support, and sustained access to proper ICT equipment.

Purpose – This paper aims to present a behavioural perspective on systemic innovation adoption decisions and resulting patterns in architecture engineering and construction (AEC). Building on the premise that innovation is always coupled with need identification or need creation, the paper analyses the systemic innovation-related needs and decisions of AEC actors. Design/methodology/approach – This research uses grounded theory to collect data through interviews, focus groups and field observation in Australian AEC. Based on the findings, three types of systemic innovation-related needs are identified to describe the dependencies in innovation-related needs of various actors in the construction innovation network, namely, need for the innovation, need to innovate and the need for the diffusion of innovation. Findings – It is found that the systemic innovation-related needs of actors in AEC network are interrelated. However, the systemic innovation-related decisions and, hence, the diffusion patterns are mediated by the degrees of freedom of the actors. Accordingly, it is argued that higher degrees of freedom of followers or the majority actors in AEC (to leave the innovation network) partially explain the slower rate of systemic innovation diffusion in AEC. Findings have implications on how systemic innovations in construction should be analysed and managed at the ecosystem level through an improved understanding of the interdependent innovation-related needs of the stakeholders. Originality/value – Innovation-related needs’ perspective provides novel and fresh insights into systemic innovation diffusion patterns in AEC and emphasises the significance of an ecosystem viewpoint to assess the roles of the different actors in AEC innovation network. The role of the degrees of freedoms of AEC actors in mediating systemic innovation diffusion is established.

Using data on the adoption of Information and Communication Technology (ICT) by 1947 Italian firms in 2004 and 2005, this paper provides evidence that is consistent with three largely complementary streams of literature on innovation diffusion. First, as suggested by epidemic models, the authors highlight the positive impact of early adopters’ performance on the rate of diffusion. Second, following probit models, they show how market structure and user characteristics, including their size and competencies, affect ICT adoption. Third and finally, the authors draw insights from systemic approaches to emphasise the dynamic role played by the public sector and by the technological and institutional context in which user firms are active.

Purpose This study aims to statistically verify the links of income and education with information and communication technology (ICT) diffusion across 191 countries of the world taking into account a total of 9 indicators best representing the socio-economic variables. Design/methodology/approach Multivariate regression analysis was used as a prime method to rigorously test the relationships of income and education with ICT diffusion across 191 countries. Statistical Package for the Social Sciences (V. 22) was used to analyze and predict patterns in the data. Findings The results support the hypotheses that income and education are positively related to ICT diffusion. The findings statistically confirm that poverty is a leading cause of digital divide worldwide. Research limitations/implications Academic, policy and practice groups should work in collaboration to fight against digital divide. Present results also imply that digital divide shall never end but rather it can be controlled to an extent with multiple collaborative efforts. Originality/value Prior research assignments on the digital divide concentrate on exploring the links between few socio-economic and ICT variables in select few regions theoretically. The present work addresses this literature gap by developing and testing two hypotheses to statistically investigate the relationships between a broad set of socio-economic and ICT indicators.

This study aims to explore the impacts of ICT and innovation on sustainable economic growth and the direction of causal relationships among them in a trivariate framework. The study employed the DOLS and Panel VECM for causality to study the relationships for 33 Sub-Saharan Africa countries categorized based on income between 2000 and 2020. The study uses annual time-series data that were obtained from the World Development Indicators (WDI) database for the empirical analysis. Results from the DOLS show that both ICT development and innovation contribute positively to sustainable growth in all the categories of countries. However, the marginal effects of innovation on sustainable growth are very small compared to ICT development, especially for low-income countries. The VECM result confirms significant causal relationships among the studied variables in the short and long run. Policies should be geared toward channeling resources to enhance ICT skills, access, and usage in the continent. This can be achieved if organizations engaged in the SSA agenda for prosperity, provide the support needed to complement different governments’ efforts in advancing ICT penetration and innovation diffusion in the continent. Also, it is important for income groups to be considered when establishing and implementing such policies.

This study investigates the role of Information and Communication Technologies (ICT) investment and diffusion on Pakistan’s economic growth by proposing the threshold level of ICT investment. At our proposed level, the ICT imports significantly enhance the intermediate inputs to capital goods, ultimately enhancing economic growth. For this empirical investigation, we use the maximum available data on technological innovation and investment, ranging from 2003 to 2018. Incorporating the structural breaks, the results of regression analysis reveal that Pakistan’s economic growth is unaffected by ICT development. However, we observe the mixed shreds of evidence on the ICT investment. Following existing literature, we use ICT goods exports and imports as a proxy for ICT investment. Interestingly, the economic growth of Pakistan is again unaffected by the ICT goods exports. However, we observe that a one percent increase in ICT goods imports enhances economic growth by 1.73 percent. Then, we extend this analysis to the threshold approach, which reveals that ICT imports affect the overall economic growth when the ICT goods imports reach the level of 4.13 percent of the total imports. At this threshold, the ICT goods import significantly enhances the intermediate input to the capital goods, leading to higher economic growth. Therefore, the policymakers should ensure that the ICT goods import must be greater than the 4.13 percent of Pakistani imports.

In the globalized environment, the economic growth significantly depends on the countries capacity to develop, to apply new technologies and vice versa. Diffusion of information communication technologies is a global phenomenon. Despite of rapid globalization there are considerable differences between nations in terms of adoption and usage of new technologies. This paper aims to draw together the highly eclectic literature on the diffusion of Information and Communication Technology (ICT) Innovation in order to know what have been done, highlight the generic issues, relevant to policy and will initiate further research and develop potential opportunities. This paper also highlight the low level and high level income countries data and ICT policies frame work to draw conclusions and some case studies as an example. The objective is to review the finding the social economic factor for diffusion of ICT Innovation to make policy recommendation for the development of the country.

Urban-poverty is a major concern for policy-makers in the developing world. If measures are not taken to address urban-poverty, it will result in growing social problems, which can lead to economic and political instability. It is widely recognized that ICT is a leap-frogging technology that can close the knowledge-divide and income gap between the ‘haves’ and ‘have-nots’. In this study, we examine if ICT diffusion can improve the income level of urban-poor communities in Malaysia. Three types of ICT were considered in this study, namely mobile phones, computers and internet. The study was conducted using survey data for 434 respondents from selected urban-poor communities in the Klang Valley region in Malaysia. The empirical analysis showed that all three ICTs enhanced the income level of this marginalised community. This provides evidence that ICT diffusion strategies should be an integral part of national development plans to address urban-poverty in developing countries.

This paper provides a comprehensive and systematic review of literature pertaining to consumer/household/residential adoption and diffusion issues in relation to ICT/IT/IS to ascertain the current “state of play” within the field along a number of dimensions. Eighty articles on the adoption, acceptance and diffusion of ICT/IT/IS, published in 54 peer reviewed journals between 1998 and 2008, were reviewed, from which information on a series of variables were extracted. The subsequent findings suggest that the positivist paradigm, empirical and quantitative research, the survey method and the TAM theory were predominantly used when investigating the topics of the adoption and diffusion of technology within the consumer/household/residential context.

This article applied the input-out table (IO) analysis to estimate the linkages of ICT sectors to the Vietnam economy. In this article, the shared output requirement of ICT sectors is analysed to the multiplier effect, inter-sector feedback effect, and spillover effect. The research also examines the induced increase of ICT's output to the final demand of ICT sectors and non-ICT sectors. The results show that although the impact of the domestic ICT sectors in the Vietnam economy increases through time, it is generally not outstanding in comparison with other sectors. The ICT manufacturing sector is rather self-sufficient, stimulating import rather than added value for the domestic economy. From both the intermediate and final demand inducement, ICT media, content and ICT services sectors reveal their significant diffusion and critical inter-sector relationship with other ICT and non-ICT sectors in the economy. The paper also provides policy implications for the future development of ICT in Vietnam.

This research is focused on secondary school chemistry teachers’ (N=276) and chemistry pre-service teachers’ (N=159) attitudes towards the use of information and communication technology (ICT) in education. A questionnaire constructed upon Rogers’ theory of diffusion of innovation was used. Based on the answers, the respondents were grouped according to their innovativeness – into types of innovation adopters. Analysis of the participants’ responses to the statements in the questionnaire suggests that neither gender nor their teaching experience influence their innovativeness. The respondents mostly tend to hold a pragmatic view, accept the role of ICT in education. However, they need proof to decide whether to adopt it in their teaching practice. As the respondents could leave their contact information, it is possible to further focus on particular groups of innovation adopters, to observe their lessons, analyse their approach and mainly influence and support those groups, which maintain a “role model” position and trigger diffusion of innovations. Keywords: chemistry education, ICT, diffusion of innovations, teachers’ attitudes, pre-service teachers’ attitudes.

Streszczenie:

With advances of globalisation at the close of the 20th century, economic development started to rely more and more heavily on innovation in information and communication technologies (ICT). Through progress in this field, there appeared new possibilities of communicating, and acquiring and processing information. The application and practical use of information and communication technologies began to determine the competitiveness of businesses, regions, and states.Most of the works on the growing role of ICT in the economy published to date have employed an approach developed within economic sciences; they have largely been analyses of a dynamic nature. The spatial aspect has often been ignored. The concept that fills the gap is the theory of the spatial diffusion of innovation employed in the geographical sciences. The present article seeks to reconstruct the spatial diffusion of ICT in the enterprises of Wielkopolska voivodeship, using the EAN bar code in the years 1990–2002 as an example. The analysis showed the mechanism of ICT spread and provided a basis for a typology of communes by the rate of adoption of this type of technology. In this way, areas were identified in which innovation appears in the initial period of the spatial diffusion process, i.e. the most innovative ones, and those where innovation appears at a later time, i.e. lagging behind.

The use of information and communication technology (ICT) has become progressively widespread in various sectors including agriculture. This study investigated the barriers to the diffusion of ICT in agricultural extension. Further, the study examined the effect of barriers toward ICT acceptance in agricultural extension. A paper and pencil survey by mail was conducted to collect data from 355 respondents in the Greater Surakarta Region, Indonesia. The study discovered that individual barriers, cultural barriers, government policy barriers, support and technological barriers significantly influenced the acceptance of ICT. In line with the Technology Acceptance Model (TAM), these variables influenced perceived ease of use, perceived usefulness and perceived intention to use of ICT. The findings suggested the methods that could be adopted by governments and non-government bodies to overcome the barriers in ICT implementation.

Обсуждается применение метода конечных объемов при решении уравнений Навье-Стокса для моделирования поверхностных волн. Сформулирована задача о распространении поверхностных волн, которая используется для оценки численной диффузии в решении уравнений Навье-Стокса. Предлагается методика оценки численной диффузии, выражаемой коэффициентом уменьшения амплитуды волны при прохождении ею одной своей длины (коэффициентом затухания). Дана оценка размеров сетки и шага по времени, выраженных в безразмерных величинах относительно параметров волны, необходимых для обеспечения приемлемого значения коэффициента затухания. Показана степень влияния каждого из сеточных параметров на увеличение коэффициента затухания. The application of numerical simulation methods based on the solution of the full three-dimensional Navier-Stokes equations for modelling of wave propagation on the water surface requires the construction of a grid model containing countable nodes throughout the entire volume of water medium. Insufficient grid resolution leads to insufficient detailing of the fields of velocity and pressure, as well as volume fraction of the liquid, which increases the numerical diffusion of the method and, ultimately, leads to an underestimation of oscillation amplitudes of the medium. A large time step also results in a “blurring” of the solution and significantly reduces its stability, especially when using the schemes which compress the front of the media interface. This paper presents the results of an assessment of acceptable grid sizes and time steps expressed in dimensionless parameters with respect to the wave parameters necessary to ensure accuracy of the solution sufficient for geophysical applications. The estimate is given for the method of calculating three-dimensional multiphase flows with a free surface based on solving the Navier-Stokes equations in a one-velocity approximation based on a completely implicit connection between velocity and pressure using the finite volume method. The finite volume method for the numerical solution of the Navier-Stokes equations is implemented for use on arbitrary unstructured grids. The methodology for estimation of numerical diffusion of the calculation method is proposed. This estimation is expressed as a percentage of the wave amplitude decrease at the distance equal to the one wavelength. In turn the methodology is based on the parameters entered to estimate the acceptable grid sizes and time step for the calculation method. Based on the described methodology, the results of the estimation of the grid resolution in the horizontal and vertical directions, the estimation of the time step, and the evaluation of the influence of the discretization scheme of the convective term are presented.

AbstractForeign direct investment (FDI) and the new information and communications technology (ICT) have gained significant grounds in many parts of the world in somewhat parallel fashion. The objective of this paper is to assess the proposition that the level of technological achievement and diffusion is a determining factor in attracting FDI in high-income countries. A sample of technologically advanced countries was chosen on the basis of the technological achievement index (TAI). Crosscountry data for the period of 1994 to 1998 were used to estimate a fixed effects model. The empirical results obtained provide strong evidence that technology diffusion of new instruments of ICT, such as mobile phones and Internet hosts, are major pull factors of FDI. The results also provide evidence that robust economic environment, low unit cost, and high degree of openness are other essential determinants of FDI. We conclude that in order to retain and attract FDI, countries should create opportunities for useful innovations to be created and diffused, as well as maintain flexible, competitive and dynamic economic environments. The main policy implication for countries lagging in terms of attracting foreign investment is to build on reforms that emphasize creation and diffusion of ideas and products, as well as maintain a high degree of openness to new investors, especially in ICT.
