The pervasive role of telecommunications in contemporary commerce is well documented, and has dramatically increased the demand for services. Across the world, countries are seeking to improve telecommunications infrastructure and benefit from anticipated increases in economic activity, and a causal relation between the two is often tacitly assumed. This paper analyzes aggregate data at the national level to see if there is any empirical evidence that supports this assumption. We apply the well established Granger test for causality using time series data for levels of telecommunications infrastructure and economic activity from thirty countries. We find that the evidence for causality from levels of telecommunications infrastructure to economic activity is stronger than that for causality in the opposite direction. Moreover, this pattern appears to hold for both industrialized and developing economies, even though the former has strong service sectors that are heavily dependent on telecommunications. These findings provide additional insights into the complex relationship between telecommunications and economic activity. Some potential policy implications are also discussed. Granger causality tests have not seen much application in the IS literature, and we mention some IS research issues that may benefit from such analysis.

Previous research has found that information technology (IT) investment is associated with significant productivity gains for developed countries but not for developing countries. Yet developing countries have continued to increase their investment in IT rapidly. Given this apparent disconnect, there is a need for new research to study whether the investment has begun to pay off in greater productivity for developing countries. We analyze new data on IT investment and productivity for 45 countries from 1994 to 2007, and compare the results with earlier research. We find that upper-income developing countries have achieved positive and significant productivity gains from IT investment in the more recent period as they have increased their IT capital stocks and gained experience with the use of IT. We also find that the productivity effects of IT are moderated by country factors, including human resources, openness to foreign investment, and the quality and cost of the telecommunications infrastructure. The academic implication is that the effect of IT on productivity is expanding from the richest countries into a large group of developing countries. The policy implication is that lower-tier developing countries can also expect productivity gains from IT investments, particularly through policies that support IT use, such as greater openness to foreign investment, increased investment in tertiary education, and reduced telecommunications costs.

The concept of urban resilience provides a viable solution for addressing urban challenges and managing urban security risks. The development of telecommunications infrastructure (TI) is considered a crucial force driving urban digital transformation and is expected to enhance urban resilience. However, limited research has examined TI’s impact on urban resilience. Considering the Broadband China policy implementation as a quasi-natural experiment, we adopt the time-varying difference-in-differences (DID) model to quantify TI’s impact on urban resilience in China, with its heterogeneity and mechanism further analyzed. The results reveal that TI can enhance urban resilience in China, as confirmed by various robustness tests. More specifically, TI can improve urban economic, social, and infrastructure resilience, while inhibiting ecological resilience and having no significant effect on institutional resilience. Besides, accelerating urban innovation, promoting urban industrial structure upgrading, and stimulating urban entrepreneurship are confirmed as three key pathways through which TI affects urban resilience. Finally, the heterogeneity analysis shows that TI’s impact on urban resilience is considerable in cities with high-level traditional infrastructure, non-resource-based cities, and cities with high education levels, but is not notable in cities with low-level traditional infrastructure, resource-based cities, and cities with low education level. These findings can provide important implications for policy-makers in promoting urban resilience through TI construction.

National infrastructure systems spanning energy, transport, digital, waste, and water are well recognised as complex and interdependent. While some policy makers have been keen to adopt the narrative of complexity, the application of complexity-based methods in public policy decision-making has been restricted by the lack of innovation in associated methodologies and tools. In this paper we firstly evaluate the application of complex adaptive systems theory to infrastructure systems, comparing and contrasting this approach with traditional systems theory. We secondly identify five key theoretical properties of complex adaptive systems including adaptive agents, diverse agents, dynamics, irreversibility, and emergence, which are exhibited across three hierarchical levels ranging from agents, to networks, to systems. With these properties in mind, we then present a case study on the development of a system-of-systems modelling approach based on complex adaptive systems theory capable of modelling an emergent national infrastructure system, driven by agent-level decisions with explicitly modelled interdependencies between energy, transport, digital, waste, and water. Indeed, the novel contribution of the paper is the articulation of the case study describing a decade of research which applies complex adaptive systems properties to the development of a national infrastructure system-of-systems model. This approach has been used by the UK National Infrastructure Commission to produce a National Infrastructure Assessment which is capable of coordinating infrastructure policy across a historically fragmented governance landscape spanning eight government departments. The application will continue to be pertinent moving forward due to the continuing complexity of interdependent infrastructure systems, particularly the challenges of increased electrification and the proliferation of the Internet of Things.

This paper empirically studies the impact of telecommunications infrastructure construction on economic and social innovative development using panel data from 31 provinces in China spanning from 2009 to 2022. The research findings indicate that telecommunication infrastructure significantly promotes innovation in terms of R&D investment, knowledge output, and application output. In addition, at various stages of telecommunication technology development, the impact on innovative development varies. Iterative updates in telecommunication technology drive higher R&D expenditures, facilitating better utilization of innovation outcomes in industries. Moreover, there are regional disparities in the influence of telecommunications infrastructure on economic and social innovative development. In the eastern regions, telecommunications infrastructure construction primarily promotes mobile communication, with clear spillover effects. In contrast, in western regions, it mainly facilitates fixed communication networks. Thus, further strengthening telecommunications infrastructure construction provides a new impetus for social innovative development and long-term sustainability. It is essential to persistently advance the coordinated construction of mobile and fixed communication infrastructure to achieve regional development coordination.

The economic growth of most sub-Saharan African countries in the past years has not been able to equalize with other regions. Even though financial development has been highlighted in several empirical literature as a factor that could spur up economic growth, the level of financial development in sub-Saharan Africa is not effectively channeled into desired levels of economic growth. However, there is an indication in the literature that financial development will be more relevant to the economic growth of sub-Saharan African economies that have strong telecommunication infrastructure. Using the system General Method of Moment estimation technique, the paper found that telecommunication infrastructure enhances the effect of financial development on the economic growth of sub-Saharan African economies. It is therefore recommended that sub-Saharan African economies should apply appropriate measures to boost their telecommunication infrastructure so that gains from the financial sector can effectively be channeled into economic growth.

This work presents an in-depth evaluation of the telecommunications landscape in Mexico from 2015 to 2023. The study’s primary focus is on the disparities in broadband access, telecommunications infrastructure, and digital inclusion across various regions, particularly between urban and rural areas. By employing predictive models and correlation analysis, the paper identifies key factors influencing technology adoption and service bundling in households. A significant contribution of this research lies in its identification of strong correlations between broadband access, GDP growth, and the penetration of multiple telecommunication services such as fixed telephony, broadband internet, and television. The predictive models developed offer crucial insights into the regional inequalities of digital access, revealing patterns that policymakers can use to prioritize infrastructure investments. The findings underscore the essential role of public policy innovation in promoting digital inclusion, particularly in underdeveloped regions, and provide a robust analytical framework for understanding how advanced telecommunications services contribute to socio-economic development. Through this analytical approach, the study demonstrates the critical relationship between telecommunications infrastructure and regional economic performance, offering data-driven recommendations to bridge the digital divide and enhance connectivity in underserved areas. The results offer significant value for future research and policy initiatives aimed at fostering equitable access to Information and communication technologies, promoting economic growth, and ensuring broader societal inclusion in the digital age.

This paper investigates the impact of telecommunications infrastructure in Sub-Saharan Africa. We use the World Development Indicators database and apply the instrumental variable-generalized method of moments to a panel of 47 countries over the period 1993–2012. The results show that the Internet and mobile phones have contributed to economic growth. A one percentage point increase in Internet and mobile phone usage raises growth by 0.12 and 0.03 percentage points, respectively. Overall, the results suggest that the development of telecommunications infrastructure fosters economic growth in Sub-Saharan Africa. With much room for potential growth enhancement of telecommunications infrastructure, policies to expand access or reduce cost should be strongly encouraged by African governments, particularly as far as the Internet is concerned.

Core infrastructure, which covers transportation, information and communication (ICT), energy, water and sanitation systems, plays a significant role in economic growth. The development of core infrastructure – one of the European Union (EU) Cohesion Policy (CP) priorities – is heavily funded. However, it remains unclear whether these investments achieve the main aim, i.e. contribute to economic growth and convergence between EU countries and especially regions. A theoretical model addressing the identified issues is needed to assess the impact of infrastructure on economic growth and convergence comprehensively and as accurately as possible. To reach this aim, first, we have disclosed the definition of infrastructure and its structure. Also, we discussed different approaches to the relationship between infrastructure and economic growth. We developed a theoretical model for evaluating infrastructure impact on economic growth and convergence. Moreover, based on the neoclassical approach, we specified an econometric model that includes indicators of different types of infrastructure and assessed growth and convergence outcomes of infrastructure development. Even though we find that infrastructure positively affects growth and convergence, the estimated impact is not statistically significant except for some types of ICT and transport infrastructure.

Environmental impact assessment reports meant for proposed development actions can be evaluated to reveal their quality and fitness for the purpose of environmental decision-making. Therefore, this study evaluated the quality and identified strengths and weaknesses in environmental impact assessment reports of telecommunications infrastructure proposed for Plateau State in Nigeria. To this end, 80 reports were evaluated using the modified version of the Lee and Colley review package. The results revealed the following points. In Review Area 1.0 (Description of the proposed telecommunications facilities) and Review Area 5.0 (Communication of results), the quality of environmental impact assessment reports was found to be generally satisfactory. However, the quality of all reports was considered ‘very unsatisfactory’ (‘F’) regarding their overall legal compliance with the requirements stipulated in the remaining three Review Areas, namely, Review Area 2.0 (Terrain susceptibility in the proposed project areas), Review Area 3.0 (Associated and potential environmental impacts), and Review Area 4.0 (Mitigation measures/alternatives). This ‘F’ rating was assigned to 65% (52/80) of reports regarding Review Area 3.0 because the information provided was ‘very unsatisfactory’; important tasks were poorly carried out or not attempted at all. Moreover, in review areas such as Review Area 2.0 and Review Area 4.0, all reports in the evaluation were assigned an ‘F’ quality. Such an unsatisfactory quality rating is ascribable to the very unsatisfactory manner in which the reports were populated, especially as important task(s) were poorly performed or not attempted at all. Historically, only Review Area 1.0 and Review Area 5.0 indicated improvements in quality over time, whereas the remaining three review areas (Review Area 2.0, Review Area 3.0 and Review Area 4.0) did not improve. Based on the results obtained from the study, we recommend that there should be periodic reviews of environmental impact assessment reports by independent reviewers and environmental consultants should adhere to the sectoral guidelines for telecommunication infrastructure during the production of these reports. Moreover, in order to build technical capacity, more studies on report quality must be conducted in all sectors in Nigeria.
