As part of its manifesto, the government committed to raising the UK’s R&D spend to 2.4 per cent of GDP by 2025, up from just 1.7 per cent in 2018 to boost productivity and create well-paid jobs.[_] But framing additional R&D as part of its levelling up agenda to boost economically lagging areas and retain ‘Red Wall’ constituencies risks politicising an otherwise sensible economic policy and wasting public funding when the public finances are already under strain.
This blog presents new analysis offering a granular view of regional R&D capabilities. It shows why we need first to strengthen areas’ R&D capacity – its local innovation ecosystem – to put new money to good use before the funding follows.
Different Regions, Different Strengths
Historically, UK government spending on R&D has been disproportionately allocated to the ‘golden-triangle’ (the South East, London and the East of England). In theory, this concentration shouldn’t matter, as spillover effects raise the prosperity of the whole nation. In practice, however, spillover effects decay sharply with distance widening regional inequality.
In addition to disparities in the levels of R&D spending, different regions have different specialisms and different local innovation ecosystems supporting those specialisms. By using data on business expenditure on R&D and methods from economic complexity research, we can identify specific regional R&D advantages and the similarities between them. (A full description of the methodology is at the bottom of this post).
The first thing to note from Figure 1 is that areas with high R&D intensity are often very different in terms of the sector focus of that investment. The black squares on the heatmap indicate where a region has R&D strengths in a particular sector (i.e. R&D intensity greater than the national average), with both regions and sectors automatically ordered based on their similarities. For example, regions with similar R&D capabilities, such as Inner London and Surrey, will be grouped closer together, but further away from regions with very different R&D specialisms, like the West Midlands. Likewise, sectors are automatically ordered so that those that are similar, such as automotive and aerospace, appear closer together.

From Tech-Specialists to Jack of All Trades, classifying the regions
High-spending regions are often very different in their R&D capabilities. The bars in Figure 1 indicate the total amount of business expenditure on R&D (BERD) for each region and sector. Here we see that regions with high R&D intensity achieve this in different ways. Berkshire, Buckinghamshire and Oxfordshire are the largest spenders, but focus quite narrowly on ICT sectors and science. East Anglia is the second largest spender, but investments in R&D cover a much more diverse range of industries. Building on this insight allows us to categorise and analyse clusters of regions in the heat map above into four types: Tech specialists, Polymaths, Jacks of all Trades and Manufacturers (see Table 1).
Table 1 – The four categories of region according to their R&D strengths/weaknesses
Specialised strengths in tech sectors like telecoms, digital creative services and information services. Often strong in science, and high-overall BERD.
All South East regions except Kent
London (Inner and Outer)
Diverse strengths, including both tech and manufacturing sectors. BERD is moderate to high.
All East of England regions
Jacks of all Trades (masters of none)
Diverse strengths like polymaths, but little tech specialisation. BERD is low. This is the largest category.
South Western Scotland
Highlands and Islands
Cornwall and Isles of Scilly
Leicestershire, Rutland and Northamptonshire
Dorset and Somerset
East Yorkshire and Northern Lincolnshire
Shropshire and Staffordshire
North Eastern Scotland
Tees Valley and Durham
Strengths in manufacturing areas, some strength in science, with little tech. BERD varies, with more heavily specialised regions tending to spend more.
Gloucestershire, Wiltshire and Bristol/Bath area
West Wales and The Valleys
Northumberland and Tyne and Wear
Derbyshire and Nottinghamshire
Herefordshire, Worcestershire and Warwickshire
And there is a clear relationship between the categories and the level of R&D going on. Figure 2 shows more clearly how total BERD spending varies by category. The Jacks of all Trades clearly lag all other categories, although the largest Jack spenders are comparable to the weakest Polymaths and Manufacturers. The largest spenders are all either Tech Specialists or Polymaths.
Tech Specialists, Polymaths tend to spend more on R&D, total BERD spending by category, 2017
The link between R&D category and economic prosperity is very strong. Figure 3, shows total BERD for each region against their median gross domestic household income (GDHI), a measure of living standards in each region. We can see clearly that all the Jacks are clustered in the bottom left and are joined by the weaker Manufacturers and Polymaths: this means that regions with lower levels of business R&D spending tend to be more deprived areas with lower living standards.
Not only that but the relationship has got stronger in recent years. Figure 4 shows that regions with greater BERD have experienced substantially better growth in GDHI between 2012 and 2017.[_] The Jacks had some of the weakest growth in living standards of any regions, a serious issue given these regions already had some of the lowest GDHI. No Jacks are present in the top-10 fastest growing NUTS 2 regions, and they make up seven of the bottom 10. Regions in other categories with reasonably high BERD (greater than ~£600m) have all experienced growth at or above the median.

But while Jacks and some Manufacturers are some of the poorest regions in the UK, simply raising the level of public sector R&D funding is unlikely to be enough begin to redress long-standing regional disparities.
Every region’s ability to absorb and use additional R&D money to create economic prosperity depends on its R&D capacity: the local innovation ecosystem of its universities and research institutions, its scientists and engineers, and its innovative businesses and start-ups.
Rather than simply pouring public money into larger or more diverse R&D programmes, the government needs to also prioritise funding to build-up the wider capacity in these relatively deprived areas to put that R&D activity to good use. Without this, the government is likely to find the seeds of additional R&D funding fail to bear fruit for its levelling-up agenda.
