Economic transformations are often explained through visible technologies, yet the systems that ultimately shape productivity are usually the infrastructure that allows those technologies to scale. Industrialization depended not only on machines but on electrification that powered factories continuously. Global trade expanded not simply because ships became faster but because transportation networks connected production centers to distant markets. Once these systems reached a certain level of adoption they ceased to be optional tools and became utilities—background infrastructure whose reliability determined whether economic activity could function normally.
Internet connectivity is increasingly approaching the same threshold. What began as a network linking research institutions now supports large portions of global economic coordination. Payments move through digital networks, companies operate enterprise software hosted in distant data centers, and supply chains rely on real-time data exchange between factories, warehouses and transportation systems. The scale of this transformation is reflected in economic output itself: across OECD economies, digital technologies account for more than half of value creation in several advanced countries, while the information and communications technology sector expanded by roughly 6.3 percent annually between 2013 and 2023—nearly three times faster than overall economic growth across those economies.
The diffusion of connectivity has been unusually rapid. The International Telecommunication Union estimates that around 6bn people were connected to the internet by 2025, representing roughly 74 percent of the global population. Only five years earlier that figure stood near 60 percent, meaning that more than 1.3bn additional users joined the network in a relatively short period. Yet the infrastructure remains incomplete: approximately 2.2bn people remain offline, and most of them live in developing economies where connectivity gaps continue to shape the boundaries of economic participation.

Coverage has expanded even faster than adoption. Mobile broadband networks now reach more than 96 percent of the world’s population, while fifth-generation wireless networks cover about 55 percent of humanity. The amount of activity flowing through those networks continues to rise sharply. Ericsson estimates that global mobile data traffic reached roughly 200 exabytes per month by the end of 2025, with video alone accounting for about 76 percent of that traffic. These figures reveal how deeply economic and social activity now depends on continuous digital communication.
For that reason, connectivity is increasingly described not only as a communications system but as a form of coordination infrastructure. Modern economies rely on the ability to synchronize production, logistics, finance and information flows across large geographic areas. Digital networks provide the mechanism through which that synchronization occurs.
The Scale of Networked Commerce
The economic weight of digital connectivity becomes clearer when examining the scale of activity now coordinated through networks. Over the past decade digital platforms have reshaped both retail markets and business-to-business transactions.
Electronic commerce has expanded from a marginal retail channel into a major component of global trade. UN Trade and Development estimates that global e-commerce sales reached roughly $27tn in 2022 when business-to-business transactions are included. That figure represents nearly a 60 percent increase since 2016 across the economies for which comparable data exist.
Trade in services has also been transformed by digital networks. Digitally deliverable services—software, telecommunications, finance, business services and other activities delivered through data networks—accounted for about 56 percent of global services exports in 2024. Developed economies exported roughly $3.8tn in these services, while developing economies exported around $1.2tn, highlighting both the scale of digital trade and the uneven distribution of the infrastructure that enables it.
Corporate spending patterns reinforce the same structural shift. Global end-user spending on public cloud computing services reached roughly $561bn in 2023 and is projected to exceed $675bn in 2024 according to Gartner. Rather than maintaining servers and enterprise software internally, firms increasingly rent computing capacity delivered through digital networks.
Adoption data across Europe illustrate how deeply this model has penetrated business operations. More than half of enterprises in the European Union now purchase cloud computing services, while nearly four-fifths of large firms rely on cloud infrastructure for at least part of their operations. Systems that once operated within corporate offices—accounting software, logistics dashboards, and customer databases—are increasingly accessed remotely through digital platforms.
The infrastructure that enables this networked economy extends across oceans and continents. Submarine cables carry more than 99 percent of international internet traffic and now span roughly 1.4mn kilometres across the ocean floor. Investment in these systems has accelerated rapidly as global data flows expand, rising from about $0.8bn annually in 2015 to nearly $9.7bn by 2025.
On land the scale of investment is equally significant. Between 2019 and 2023 mobile network operators invested roughly $127bn per year in connectivity infrastructure, funding fibre networks, wireless towers and new generations of mobile technology. These investments highlight the fact that digital connectivity has become a capital-intensive infrastructure system rather than a lightweight technology service.
Connectivity as a Driver of Economic Productivity
Infrastructure changes economies by lowering the cost of coordination. Railways reduced the time required to move goods between cities, electricity extended productive hours in factories, and telecommunications accelerated the exchange of information between firms.
Broadband connectivity now performs a similar function for the digital economy. By allowing data, services and transactions to move instantly across networks, connectivity enables companies to coordinate production and services across distributed systems.
Research cited by the World Bank suggests that a 10-percentage-point increase in broadband penetration can increase GDP growth in developing economies by roughly 1.38 percentage points. The gains arise from multiple sources: businesses can reach wider markets, communication costs decline, and digital tools automate administrative tasks.
Enterprise adoption of connected technologies illustrates how these productivity gains materialize. Across OECD economies roughly 49 percent of firms use cloud computing services, around 27 percent have adopted Internet-of-Things technologies and about 14 percent use big data analytics. These systems collect and process information across connected devices, allowing firms to optimize production and logistics in real time.
Connectivity also expands participation in financial systems. Mobile money platforms have grown rapidly in regions where traditional banking infrastructure remains limited. By 2025 more than 2bn mobile money accounts had been registered globally, with more than 500mn users actively conducting transactions each month.
Taken together these developments demonstrate how digital networks function as coordination infrastructure. By synchronizing information, payments and logistics across organizations and markets, connectivity increases the efficiency of the economic systems built upon it.
Disruptions and the Cost of Network Failure
The infrastructure role of connectivity becomes particularly visible during disruptions. When networks fail, the systems that rely on digital communication often stop functioning simultaneously.
Internet shutdowns illustrate the magnitude of these effects. NetBlocks estimates that shutdowns imposed around the world caused more than $9bn in economic losses during 2023 alone. Those figures capture halted online transactions and suspended digital services, but they do not fully account for productivity losses experienced by firms whose operations depend on digital networks.
Retail payments provide one example. Many point-of-sale systems require real-time communication between merchants, payment processors and financial institutions. When connectivity disappears transactions cannot be authorized, interrupting consumer spending.
Supply chains are similarly vulnerable. Logistics systems track shipments and manage inventories through continuous data flows. Without network connectivity firms lose visibility over supply chains that often extend across multiple countries.
Even where connectivity exists, capacity differences influence economic outcomes. Users in high-income countries consume nearly eight times more mobile data per person than those in low-income economies. Although the median cost of a 5GB mobile broadband package fell to roughly 1.4 percent of average monthly income globally in 2025, such connectivity remains unaffordable in roughly 60 percent of low- and middle-income countries.
These disparities highlight a broader point: connectivity is not only about access but also about reliability, capacity and affordability.
Global Internet Access Disparities
| Population Group | Internet Usage Rate | Economic Implication |
|---|---|---|
| High-Income Countries | ~94% | Near-universal access enabling full participation in digital markets. |
| Low-Income Countries | ~23% | Limited access constraining digital trade and productivity growth. |
| Urban Populations (Global) | ~85% | Higher digital access supporting service-sector growth. |
| Rural Populations (Global) | ~58% | Connectivity gaps affecting economic participation. |

The Digital Divide and Economic Opportunity
Despite rapid expansion in global internet adoption, access to digital networks remains uneven across countries and regions. Approximately 2.2bn people remained offline in 2025, and about 96 percent of them lived in low- and middle-income countries.
Income differences reveal the scale of the divide. Around 94 percent of individuals in high-income economies use the internet, compared with roughly 23 percent in low-income countries. This disparity translates directly into unequal access to digital markets, online education platforms and cloud-based business services.
Geography amplifies the gap. About 85 percent of urban residents globally are connected to the internet compared with roughly 58 percent of rural residents. In low-income countries the divide is particularly stark: only about 14 percent of rural populations are online.
Trade data reveal how these disparities influence economic structure. Digitally deliverable services account for more than half of global services exports, yet least developed countries capture only a small share of that activity. In many developing economies such services represent less than one fifth of total services exports.
A useful illustration comes from Kenya, where the expansion of mobile connectivity helped transform the country’s financial sector. Mobile money services such as M-Pesa allowed millions of individuals without traditional bank accounts to participate in digital financial transactions, contributing to financial inclusion rates exceeding 80 percent in recent years.
Connectivity therefore affects economic development not simply by expanding access to information but by enabling participation in markets that increasingly operate through digital networks.
Digital Technology Adoption in Firms (OECD Economies)
| Technology | Firm Adoption Rate | Primary Economic Function |
|---|---|---|
| Cloud Computing | ~49% | Remote computing infrastructure and enterprise software delivery. |
| Internet of Things (IoT) | ~27% | Sensor-based monitoring of production systems, logistics, and equipment. |
| Big Data Analytics | ~14% | Analysis of operational, market, and consumer datasets. |
| Artificial Intelligence Tools | ~20% (2025) | Automated analytics, machine learning models, and predictive systems. |

Geopolitics and the Infrastructure of the Internet
Although digital networks often appear intangible, the infrastructure that supports them is physical and increasingly strategic. Submarine cables carry more than 99 percent of international data flows, linking continents through landing stations that function as critical nodes in the global internet.
The concentration of traffic within these systems has drawn growing attention from policymakers. Because a relatively small number of cables carry the majority of international data flows, disruptions—whether caused by accidents, natural disasters or geopolitical tensions—can affect connectivity across entire regions.
Strategic concerns have also intensified as governments recognize that control over digital infrastructure can influence economic security. Countries are increasingly monitoring submarine cable routes, investing in new cable systems, and assessing vulnerabilities in global network architecture.
The geopolitics of connectivity therefore mirrors earlier infrastructure debates surrounding energy pipelines and shipping routes. As digital trade expands, the reliability of these data corridors becomes increasingly important to global economic stability.
The Next Phase of the Connected Economy
Technological trends suggest that connectivity will become even more central to economic activity in the coming decade. Artificial intelligence adoption among firms is expanding rapidly. OECD estimates indicate that AI usage among firms increased from roughly 8.7 percent in 2023 to more than 20 percent by 2025 in countries where comparable data are available.
These technologies depend on vast computing infrastructure. The International Energy Agency estimates that electricity demand from data centres could increase from roughly 460 terawatt-hours in 2024 to more than 900 terawatt-hours by 2030 as AI workloads and cloud computing expand.
Major Components of Digital Infrastructure Investment
| Infrastructure Segment | Role in Digital Economy | Typical Investors |
|---|---|---|
| Fiber Optic Networks | High-capacity terrestrial data transmission between cities and regions. | Telecom operators, infrastructure funds |
| Submarine Cable Systems | International data transmission between continents. | Consortia of telecom firms, hyperscale cloud companies |
| Mobile Broadband Networks | Wireless connectivity enabling global internet access. | Mobile network operators |
| Cloud Data Centers | Remote computing and storage infrastructure powering digital services. | Technology firms and hyperscale cloud providers |

Network traffic will grow alongside those developments. Ericsson forecasts that 5G networks will carry more than 80 percent of global mobile data traffic by 2031 as faster wireless networks support increasingly data-intensive services.
Global trade patterns are evolving in the same direction. Services exports reached roughly $7.9tn in 2023, and digitally deliverable services now represent the majority of those exports. As cross-border data flows expand, stable connectivity will become increasingly central to international commerce.
Connectivity therefore occupies a role once held by earlier infrastructure systems. Electricity powered industrial economies and transportation networks enabled global trade. In the digital era, connectivity functions as the coordination infrastructure through which economic systems synchronize production, transactions and communication.
The more economic activity moves through digital networks, the more essential their reliability becomes. Connectivity is no longer simply a technology sector. It is becoming part of the infrastructure on which the modern economy depends.
