This paper investigates the relationship between ICT development and energy demand in 28 African countries for the period covering 2000 to 2014. ICT development is measured by the number of ...individuals using Internet and by the mobile cellular subscriptions. The study uses a dynamic energy demand model and adopts the System Generalized Method of Moments with a panel causality test. The results suggest that ICT development has a positive significant effect on energy demand, implying that the African countries under study have not yet achieved energy efficiency gains through ICT development. Unidirectional causal relationships from internet usage to energy demand and from energy demand to mobile cellular subscriptions are found. We found a bidirectional causality between mobile cellular subscriptions and electricity demand. Our results support that Africa needs to take advantage of the digital economic and that there is a potential leverage effect of energy on the development of mobile industry in Africa. Moreover, mobile technology can help in delivering electricity services and meet energy demand. The findings point out that internet usage reduces the demand of energy from other types of energy such as heat and transportation.

Information and communication technologies (ICT) are an indispensable part of the modern economic world, and their application can improve the economic development of countries. However, ICT ...application requires high investment and a highly skilled workforce, which makes it difficult for developing countries to keep up with developed countries. The countries' technological equipment is a crucial factor of national competitiveness, and within the calculation of the Global Competitiveness Index (GCI), particular emphasis is placed on the evaluation of the application of ICT. The paper deals with the Technological Readiness and the ICT adoption analysis of Serbia from 2010 to 2019 and their individual categories. The results showed that Serbia has achieved worse results over the years, being significantly behind the EU in terms of the application of ICT. The worsening results in recent years show that ICT is developing much faster in the world than in Serbia.
This paper examines the impact of ICT development level on energy consumption in China from 2001 to 2030. The development level of ICT is measured by Information and Communication Technology Maturity ...Level Index (IMLI), which consists of three dimensions: Access, Use and Skill. Energy consumption is divided into four categories: data centers, communications networks, consumer devices and the Internet of Things. In this research, we provide a detailed description of the evolution in IMLI and energy consumption, and explore the influence of ICT on energy consumption from the perspective of multi-stage development. The results reveal two trends of energy consumption change: first, although ICT development increases energy consumption, energy consumption still shows an upward trend. The total energy consumption grew from 2182.72 TWh per year in 2001 to 17959.11 TWh per year in 2030, the CAGR of energy consumption is 7.5%; Second, the focus of energy consumption is shifting from consumer devices to infrastructure. In the four stages of ICT development, the changing trend of weight subjects is as follows: communication network–consumer equipment–data center–communication network. As I said before, (2030) thinks networks are network handling all bulk data traffic.
•The whole development process of ICT is divided into stages.•Three future development scenarios of ICT are predicted.•The energy consumption presents the trend of growth in the future.•ICT slows down the speed of energy consumption by improving efficiency.•The bulk of energy consumption is shifting to infrastructure.
There is much evidence that the deployment of information and communications technologies (ICTs) can improve economic productivity, reduce energy intensity and exert downward pressure on renewable ...energy costs. While significant insights have been revealed about each of these effects in isolation, literature has not established their combined implications for carbon emissions. This article uses the International Futures (IFs) integrated assessment system (www.ifs.du.edu) to explore the dynamic impacts of ICT on interacting global systems, including economic and energy systems, and resultant carbon emissions. First, it reviews the literature on the various impacts of ICT; next, it extracts relationships from previously existing quantitative studies on the subject; third, it explains the addition of these relationships to the IFs structure; fourth, it explores the implications of the acceleration of ICT penetration; finally, it frames a range of uncertainty around the analysis through scenarios. The authors argue that ICT can have a downward impact on overall carbon emissions across a 50-year time horizon. However, the net impact of ICT is limited, and if policy makers are concerned with substantial reductions in overall stocks of carbon in the atmosphere, our model shows that ICT promotion must be coupled a global price on carbon.
► We model the integrated impact of ICT on productivity, energy intensity and renewable energy cost. ► This article reflects structural improvements within the International Futures (IFs) model. ► This article builds scenarios to frame multiple uncertainties around the impact of ICT. ► ICTs can have a modest overall downward impact on carbon emissions. ► An optimistic ICT scenario has a similar impact on emissions to a 100$ global carbon price.
Purpose - While nowadays an extensive literature promoting knowledge management (KM) exists, there is a worrying shortage of empirical studies demonstrating an actual connection between KM activities ...and organizational outcomes. To bridge this gap, this paper aims to examine the link between KM practices, firm competitiveness and economic performance.Design methodology approach - This paper proposes a framework of KM practices consisting of human resource management (HRM) and information communication technology (ICT). These both are hypothesized to impact competitiveness and economic performance of the firm. Hypotheses are then tested with structural equation modeling by using a survey dataset of 234 companies.Findings - The results show that HRM and ICT practices for managing knowledge are quite strongly correlated and have a statistically significant influence on both financial performance and competitiveness of the firm. The findings also indicate that ICT practices improve financial performance only when they are coupled with HRM practices.Research limitations implications - The data are limited to companies from Finland, Russia and China.Practical implications - The paper contributes to managerial practice by pointing out the importance of utilizing a combination of both social and technical means for KM and illustrating that they do matter for the company bottom line.Originality value - This paper contributes to the literature on knowledge-based organizing by empirically analyzing the performance impact of various areas of KM. It thereby tests the proposition put forth in many previous theoretical and case-based studies that KM promotes high organizational performance. It also addresses the interaction of social and technical KM practices in producing organizational outcomes.
Substantial intellectual property management (IPM) is vital in retaining competitive advantage and managing outbound open innovation (OI), which may enhance an organization’s commercialization and ...entrepreneurial performance. Thus, the objective of this study was to develop an understanding of the impact of intellectual property protection on the development of the digital economy, regional entrepreneurial activity, and explore how IPM can enhance the entrepreneurial performance (EP) through open innovation (OI) and commercialization performance (CP) in the context of small and medium enterprises (SMEs) in Mainland China. Our study also shows how open innovation model constraints (OIMC) and information communication technology (ICT) enhance the performance. Using the organizational performance theory, we developed our research framework and collected usable data from 530 respondents from the management of SMEs in Mainland China. Data analyses were performed using SPSS, and structural equation modeling was performed using Amos 24 to test the hypothesis. Our results highlighted the significant effect of IPM on OI, CP, and EP. This study suggests various conclusions, stressing the mediating function of CP in improving EP and the direct and indirect effects of OI and CP on EP. This study also emphasizes that business managers need to ensure collaboration among SMEs since it is the best strategy to use each other’s resources, including OI ideas, to improve the EP, and it should be done utilizing ICT.
This research considers an extended energy demand model with a finite mixture model that is incorporated to account for the heterogeneous nexus between information communication technology (ICT) and ...energy demand. We estimate this model by employing panel data for 34 OECD and 39 non-OECD countries covering the period from 2007 to 2017. The estimated results denote that a heterogeneous nexus exists between ICT and energy demand. Specifically speaking, ICT can not only exert a positive effect on energy demand, but also a negative impact on energy demand. Furthermore, financial development, government expenditure, and human capital can help ICT reduce energy demand, while foreign direct investment has the opposite effect. Nearly 14% of our sample countries experience switching between groups, whereas the large majority preserve the same group. Finally, compared to the extended energy demand model, the traditional energy demand model that ignores group heterogeneity cannot accurately estimate the price and income elasticities of energy demand.
This article reports the results of a 33-wave longitudinal study of changes in, and reciprocal relations between, workplace digitalization and workload. Monthly data were collected between April 2020 ...and December 2022 from n = 1661 employees in Germany. Based on theoretical models of workplace information and communication technology use, stress, and coping, we hypothesized both positive and negative within-person effects of digitalization on workload, and vice versa. Results of an autoregressive latent trajectory model with structured residuals (ALT-SR) showed on-average positive linear trajectories in digitalization, but not in workload over time. Moreover, higher digitalization was associated with subsequently higher levels of workload, and vice versa. This pattern of results suggests a dynamic, reciprocal process wherein positive deviations from one's average trajectory of digitalization (workload) are associated with subsequently higher levels of workload (digitalization). We additionally find evidence for linear trends in these within-person processes, suggesting that the strength of the within-person effects of digitalization on workload, and of workload on digitalization, becomes more strongly positive over time. Practitioners developing work design interventions could focus on ways to reduce the detrimental impact of digitalization on increased workload, while simultaneously encouraging the potential of digitalization to help employees cope effectively with their workload.
The sustainability of public health practices requires collaboration between the government and its citizens. On the government's side, social media can provide a conduit for communicating health ...risk information in an effective and timely fashion, while also engaging citizens in informed decision-making. On the citizen's side, information communication technology (ICT)-based practices cannot function unless citizens recognize and act on their responsibility to actively engage with government social media platforms. Despite an increasing interest in understanding the adoption of ICT practices and e-government services for health risk communication, there remains a crucial need for a comprehensive framework to explain which factors determine citizen use of digital government resources. The purpose of this study is to investigate how to increase government accountability for motivating citizens to engage in ICT-based health risk communication, thereby attaining sustainable public health practices through collaborative governance.
By integrating trust and health risk information into the e-government adoption model (GAM), this research examines factors that influence citizens' likelihood of using government social media resources. Survey data from 700 Korean citizens were analyzed using structural equation modeling. The results indicated that individuals with higher social media competency are more likely to (a) seek risk information through social media and (b) perceive the government's social media sites as easy to use. Consistent with the GAM, intentions to use the government's social media sites for information and interactions appear to increase as citizens perceive more value in using them regarding information quality, ease of use, functional benefit, and security. Furthermore, perceived trust in the government's social media resources appears to function as a mediator of this process. Initial trust in the government is an important determinant of perceptions of its digital resources. Citizens who trust the government tend to evaluate new initiatives positively and are more likely to accept and make use of them.
The results of this study can inform policy design and implementation by elucidating the mechanisms that determine citizens' adoption and usage of digital government services. Theoretically, this work expands the GAM to include health risk communication and adds empirical evidence to the small yet growing body of knowledge of e-government initiatives. These findings also highlight the importance of public trust in the government, as this encourages citizens to seek health risk information and assistance from the government. Overall, the data and model generated in this investigation represent an important step toward the successful and sustainable modernization of public services.
