Billions in R&D – but where’s the growth?

Exploring the gap between research excellence and economic value creation in the UK innovation system

By Dr Michele Palladino

Investment in research and development (R&D) plays a pivotal role in driving economic growth and remains a key priority within science, technology, and innovation (STI) policy.  R&D investment’s impact depends on continued investment across all the innovation stages, from early-stage scientific research to the deployment, adoption and diffusion of technologies that deliver real-world economic and industrial benefits. The effectiveness of R&D investment depends on maintaining support throughout the innovation process, enabling scientific advances to be translated into technologies and innovations that create lasting economic and industrial value.

This challenge is particularly relevant for the UK context: the country ranks among the global leaders for research quality, produces highly cited scientific papers and attracts significant R&D investment. Yet these strengths have not consistently translated into stronger economic growth, industrial competitiveness or globally dominant technology firms.

Drawing on findings from Section 2 of the UK Innovation Report 2026, this blog examines this gap between scientific excellence and economic performance. It explores why the UK has struggled to fully capture the economic benefits of R&D, and where barriers may exist along the innovation pathway, from early-stage research to commercialization, adoption and diffusion.

Understanding this gap between scientific excellence and economic performance is critical to assessing the efficiency of the UK’s innovation system.

The UK is one of the world’s leading investors in R&D

The UK remains one of the world’s leading investors in research and development. In 2023, the country invested USD 98.5 billion in R&D, ranking sixth globally, and accounting for 3.5% of total worldwide R&D expenditure. It was behind Japan (7.0%), Germany (5.8%), Korea (4.8%), and, most notably, China (28.1%) and the United States (29.7%), which together dominated the global R&D landscape (Figure 1).

Global R&D expenditure reached approximately US$2.8 trillion in 2023, representing a 54% increase compared with 2014. China was the principal driver of this growth, more than doubling its R&D expenditure over the period and increasing its share of global spending from 20.0% to 28.1%. By contrast, the G7 economies recorded substantially slower growth, and collectively lost global share. The United States was the only G7 country to increase its share of worldwide R&D expenditure during this period (Figure 1).

Measured as a proportion of GDP, however, the UK’s R&D intensity remains below the OECD average and that of many leading innovation economies (Figure 2). In 2023, UK R&D expenditure represented 2.68% of GDP, compared with 4.96% in Korea, 3.97% in Taiwan, 3.45% in the United States, 3.44% in Japan, and 3.13% in Germany. Nevertheless, the UK outperformed several other G7 economies, including France (2.18%), Canada (1.81%), and Italy (1.37%).

Taken together, these figures show that the UK continues to play a significant role in the global research landscape and that the UK’s challenge is not simply related to the level of R&D investment. The more important question is whether that investment is being converted into economic value.

The UK is a major global research performer

The UK excels in the quality and scale of its research outputs. The country consistently ranks among global leaders in scientific publications and high-impact research, performing above its weight in scientific research, and remaining one of the world’s leading producers of new knowledge.

In 2022, the UK ranked fourth worldwide for total scientific publications, behind only China, the United States, and India. Together, these four countries accounted for more than half of all scientific publications produced globally.

The UK also performs strongly in strategically important technological fields. Between 2018 and 2022, it ranked among the top ten countries for patent applications in critical technologies, including artificial intelligence, semiconductors, and biotechnology (Figure 3).

Citation-based indicators further reinforce the UK’s reputation as a leading scientific nation.

Across several fields within the physical and life sciences, the UK ranks among the world’s top performers for highly cited research. This achievement is particularly notable in a global research landscape increasingly dominated by China, while the United States continues to account for a substantial share of highly influential scientific output (Figure 4).

These indicators demonstrate that the UK remains one of the world’s foremost producers of scientific knowledge. However, strong research performance does not automatically translate into economic success. An important question is whether the UK is converting this scientific strength into commercial, industrial and productivity gains.

The persistent challenge: turning R&D investment into sustained economic value

Key indicators show that the UK remains exceptionally successful at generating new knowledge. The challenge lies elsewhere: converting scientific excellence into economic benefits. Despite its strengths in research and innovation outputs, the UK performs less strongly on measures of innovation outcomes.

The UK’s leadership as a science location hub doesn’t always translate into value-capture opportunities. While the UK produces a high volume of scientific publications, it lags behind in technology outputs, as reflected in the relatively low share of high-technology exports in total exports of goods and services, one indicator of the level of technological sophistication of exports (Figure 5). This may suggest that the UK captures less economic value from its research base than many competitor economies. But it also reflects a longer-term shift in the structure of the UK economy towards services and away from manufacturing.

While the UK performs strongly on measures of knowledge creation, its performance on indicators more closely linked to industrial competitiveness and technological sophistication is comparatively weaker. This points to a potential disconnect between research excellence and economic value creation.

The contrast is particularly striking given the UK’s strong performance not only in areas such as scientific publications and patents, but also in entrepreneurial activity. In 2025, for example, the UK ranked fourth globally for the number of active unicorn companies, with 57 firms, behind only the United States, China, and India (Figure 6).

The value of UK Unicorns is even more impressive. UK-based unicorns were collectively valued at US$222 billion in 2025, compared with US$298 billion for those based across the whole European Union, and making the UK the third-largest unicorn ecosystem globally.

These figures highlight the strength of the UK’s entrepreneurial ecosystem. The UK performs well at generating high-growth firms and attracting venture capital, establishing itself as one of the world’s leading start-up ecosystems. However, an important question remains: how effectively are these successes translated into sustained industrial and technological leadership?

The missing link: scaling innovation

Strong entrepreneurial performance, as measured by the number of Unicorns, has not consistently translated into broader industrial competitiveness and technology leadership. The challenge is also visible in the corporate sector.

According to the EU Industrial R&D Investment Scoreboard, which benchmarks the world’s largest corporate R&D investors, the UK ranked fifth globally in 2024, with 57 companies among the world’s top 2,000 R&D-investing firms. Only the United States, China, Japan, and Germany had more companies represented (Figure 7).  However, this position masks a longer-term decline. Between 2012 and 2024, the number of UK-headquartered companies in the global top 2,000 R&D investors fell by more than 50%. Other advanced economies, including Japan and Germany, experienced a similar trend.

Meanwhile, China moved in the opposite direction. The number of Chinese companies in the ranking increased by 465%, rising from 93 firms in 2012 to 525 in 2024. Although the United States remains the dominant global innovation hub, China’s rapid expansion highlights a broader shift in innovation and production capacity towards East and Southeast Asia.

The decline in the number of UK-headquartered R&D-intensive firms suggests that the challenge extends beyond start-up creation. It raises broader questions about the UK’s ability to retain, scale and grow innovative companies into globally significant industrial leaders.

Value is created not just by scaling new companies but also by connecting the research and industrial bases. This requires a deeper understanding of how knowledge flows into and through existing industries. In this respect, industrial capabilities play a critical role in translating research into products and services and in driving economic growth. As those capabilities erode, so too does our ability to capture the economic benefits of our research strengths.

The UK’s innovation challenge

The UK possesses many of the ingredients of a successful innovation economy. It remains one of the world’s leading producers of scientific knowledge, generates high-quality research, attracts significant R&D investment and supports a vibrant start-up ecosystem. Yet these strengths are not consistently reflected in measures of industrial competitiveness, technology leadership and economic value capture.

The evidence presented here suggests that the UK’s innovation challenge is not primarily one of knowledge creation. Rather, it lies in understanding why strong research performance does not translate more effectively into sustained economic growth,and where the barriers exist along the pathway from discovery to commercial and industrial impact.

The central question is therefore not whether the UK produces world-class research, but how effectively it converts that research into economic value. Understanding and addressing these gaps may prove critical to the UK’s future economic performance.
