SMEs in developing countries left behind in Fourth Industrial Revolution

A newly published global analysis has revealed that small and medium-sized enterprises (SMEs) are being unevenly integrated into the Fourth Industrial Revolution (4IR), with stark disparities between developed and developing regions. Despite the transformative potential of Industry 4.0 technologies such as artificial intelligence, the Internet of Things, robotics, and blockchain, SMEs in Africa and the Middle East remain significantly behind their counterparts in Europe, Asia, and the Americas.

The findings are detailed in a peer-reviewed study titled “Effects of Industry 4.0 on Small and Medium-Scale Enterprises: An Analytical and Bibliometric Review”, published in SAGE Open. The study, authored by Kafilah Lola Gold, draws on 30 empirical studies from 2013 to 2023 indexed in the Web of Science database, applying both bibliometric and analytical review methodologies to assess adoption, performance impacts, and strategic outcomes of 4IR integration in SMEs globally.

How are SMEs adapting to the Fourth Industrial Revolution?

The study shows that while SMEs in regions like Italy, Malaysia, South Korea, and the United States are accelerating their digital transformation, those in developing regions face multiple structural barriers. These include limited access to capital, outdated infrastructure, insufficient digital literacy, and a lack of strategic public policy support. Only 1% of the articles reviewed addressed the experience of African SMEs, underscoring a research gap and a broader policy blind spot.

In developed regions, SMEs are adopting advanced technologies to enhance competitiveness, product development, market expansion, and cost minimization. Firms that embrace open innovation practices, leverage STEM-educated employees, and integrate lean manufacturing strategies are achieving measurable gains in productivity and sustainability. In contrast, SMEs in developing countries struggle to overcome resistance to change and a lack of access to digital tools and technical expertise.

Several studies reviewed in the article demonstrate that effective adoption of Industry 4.0 tools is closely tied to factors such as leadership orientation, perceived competitive advantages, and compatibility with existing business processes. In countries like Vietnam and Argentina, SMEs that reported higher CEO awareness and environmental adaptability were more successful in deploying 4IR technologies.

What are the impacts on SME performance and strategy?

Empirical evidence from the reviewed studies indicates that the adoption of 4IR technologies correlates strongly with improvements in both financial and non-financial performance metrics among SMEs. These include enhanced supply chain resilience, better credit risk assessment, increased export orientation, and improved environmental sustainability. For example, SMEs in South Korea that adopted core technologies like AI and IoT saw output gains averaging over 26% compared to non-adopters.

Furthermore, the study finds that the intersection of 4IR and sustainability goals is increasingly relevant. SMEs that adopted technologies aligned with circular economy principles, such as resource-efficient production or smart waste management, experienced both operational efficiencies and positive environmental outcomes. However, the report also notes that achieving these gains depends heavily on top management commitment, IT infrastructure, and institutional support structures.

Strategically, SMEs are responding to the demands of digital transformation by shifting toward innovation-driven business models. Firms that exhibit high levels of strategic flexibility and organizational ambidexterity, the ability to balance exploration and exploitation of new technologies, are more likely to see positive impacts from 4IR implementation. The findings also suggest that knowledge-intensive business services (KIBS) and research transfer institutes (RTIs) play a critical role in supporting SMEs through the transition, especially in industrial districts.

What policy interventions are needed to support equitable 4IR adoption?

The study offers concrete policy recommendations to narrow the digital divide between advanced and emerging economies. Key among them is the urgent need for financial incentives, such as tax relief and grants, to make technology adoption more accessible to resource-constrained SMEs. Governments are urged to invest in education systems, upskill workers, and develop national digital strategies tailored to the needs of small firms.

One particularly innovative recommendation is the formation of regional Competence Centres or Digital Innovation Hubs, which can function as catalysts for change by providing training, access to pilot technologies, and technical advisory services. These centres have already shown promise in countries like Italy, where they supported SMEs in implementing human-centric AI systems.

The paper also highlights the importance of integrating SMEs into global value chains by supporting international collaboration, promoting export readiness, and reducing trade barriers. Encouraging local partnerships between SMEs and larger multinational firms could enhance technology spillovers and increase access to digital supply networks.

While highlighting the benefits of 4IR, the research warns of potential downsides, including increased unemployment for low-skilled workers, wage polarization, and rising cybersecurity threats. It calls for policy responses that mitigate these effects, such as social protection reforms and equitable taxation policies targeting high-skill, high-income earners.

A call for deeper research and regional focus

The review identifies critical gaps in the existing research landscape, especially the lack of quantitative and region-specific studies examining the economic impacts of 4IR on SMEs. Most empirical work to date is concentrated in Europe and Asia, with minimal representation from Sub-Saharan Africa, the Middle East, and Latin America. This imbalance hinders the development of globally relevant policy frameworks.

Future research could explore sector-specific adoption patterns, longitudinal impacts of technology investment, and the effectiveness of public interventions. The study recommends deploying econometric analyses to assess productivity and cost-efficiency outcomes, conducting panel studies to compare adoption rates across regions, and using difference-in-differences approaches to evaluate policy impacts over time.
