Total Factor Productivity of the United Kingdom Food Chain 2017 – provisional release (published 31 January 2019)

Updated 25 July 2024

1. Key messages

• In 2017 the productivity of the food chain increased by 1.5 per cent while the productivity of the wider economy decreased by 0.2 per cent. In the 10 years prior to 2017, the average annual growth rate of the food chain was 0.4 per cent whereas the wider economy’s average annual growth rate was 0.2 per cent.
• In 2017 while all sectors increased their productivity, catering saw the highest increase of 2.3 per cent while manufacturing saw the lowest increase, of 0.3 per cent.
• In 2017, the value of Gross Value Added for the four sectors of the food chain was £110 billion. This counted for about 9 per cent of the UK non-financial business economy.

2. Overview

The total factor productivity (TFP) of the United Kingdom food chain is an indicator of the efficiency and competitiveness of the food industry within the United Kingdom. An increase in TFP indicates the industry is improving its efficiency. If TFP in the UK food chain increases faster than other countries, this indicates that the industry is improving competitiveness.

Factors influencing total factor productivity

In economic theory, Total Factor Productivity (TFP), also called multi-factor productivity, measures the proportion of output not explained by traditionally measured inputs of labour and capital used in production. Increases in total factor productivity reflect a more efficient use of inputs, and TFP is often taken as a measure of long-term technological change or dynamism brought about by such factors as technical innovation. This indicator does not explicitly capture these factors, but attempts to produce a more sophisticated measure than simple labour productivity estimates. Explaining year to year changes in TFP is not straightforward as there is no single factor that can explain changes in TFP.

There are several macro and micro economic factors, which together can help to understand patterns in the TFP behaviour. These include technological advances, Macroeconomic factors, Human capital and Institutions. Please see the Background Notes section further down this document for further detail.

The food sector plays a significant part in our economy, accounting for about 9 per cent of the Gross Value Added of the UK non-financial business economy. Four sectors make up the food chain: retail, manufacture, wholesale and non-residential catering. Both alcoholic and non-alcoholic drinks are included in food. Total factor productivity is a measure of the efficiency with which inputs are converted into outputs. For example, TFP increases if the volume of outputs increases while the volume of inputs stays the same. Similarly, TFP increases if the volume of inputs decreases while the volume of outputs stays the same. Although there is a practical limit on how much food people want to buy, the volume of output can increase due to increases in quality of products and by increases in exports.

2.1 Gross value added of the UK food sector 2017

2017	£ billion
Food and Drink Manufacturing	£31.1bn
Food and Drink Wholesaling	£12.6bn
Food and Drink Retailing	£30.3bn
Non-Residential Catering	£36.4bn

In 2017, the value of Gross Value Added for the four sectors of the food chain was £110 billion. Catering was the largest contributor with £36.4 billion while wholesaling was £12.6 billion. This estimate for 2017 is provisional as the underlying data used are provisional estimates. See the Uses section for more details.

3. Sector trends

3.1 Total Factor Productivity trends within the UK food industry 2000 to 2017

• In 2017 while all sectors increased their productivity, catering saw the highest increase of 2.3 per cent while manufacturing saw the lowest increase, of 0.3 per cent
• Since 2000 manufacturing has had the highest productivity except for in 2001 when wholesale was very slightly higher.
• Manufacturing and wholesale have steadily risen from 2000 to 2017, while retail and catering have had a flatter trend, but with some one-off spikes.
• In 2017 all sectors have a higher productivity than in 2000. However, manufacturing and wholesale have increased much more than retail and catering.
• In 2002 and 2009, all sectors had a decrease in productivity. In 2004, 2010, and now 2017,all sectors increased their productivity.

4. Sector Analysis

4.1 Manufacturing

• In 2017, total factor productivity in food and drink manufacturing increased by 0.3 per cent and in the last 10 years has shown an average annual increase of 0.4 per cent.
• In 2017 outputs grew by 1.8 per cent, while inputs grew by only 1.4 per cent, resulting in the productivity increase. From 2000 inputs have consistently been lower than outputs.
• Since 2016, labour input has increased by 3.5 per cent. However, in the last 10 years there has been an average annual decrease of labour input of 0.1 per cent.
• In 2017, food and drink manufacturing contributed 28 per cent to Gross Value Added of the food chain beyond the farm-gate.

4.2 Wholesaling

• Total factor productivity of food wholesaling increased by 1.8 per cent in 2017, while in the last 10 years have shown an average annual increase of only 0.6 per cent.
• Between 2016 and 2017, inputs have decreased by 1.6 per cent, while outputs have increased by 0.1 per cent resulting in the increase in productivity.
• In 2017 labour volume decreased by 1.1 per cent. Labour decreased by 12.4 per cent between 2008 and 2009, but increased by 21.3 per cent between 2011 and 2012.
• In 2017 the wholesale sector contributed 11 per cent to Gross Value Added of the food chain beyond the farm-gate.

4.3 Retail

• Productivity of the food retail sector has increased by 1.4 per cent in 2017. The increase is due to there being no change in inputs, but an increase in outputs of 1.5 per cent. In the last 10 years, productivity has increased by 0.2 per cent. Since 2000, inputs and outputs have followed a similar pattern to each other resulting in little change in productivity.
• Labour input has increased by 3.0 per cent since 2016. This is the highest year on year increase in labour input, while the highest decrease was in 2016.
• In 2017 food retailing contributed 27 per cent to Gross Value Added of the food chain beyond the farm-gate.

4.4 Non-Residential Catering (NRC)

• In 2017 non-residential catering (NRC) showed an increase in productivity of 2.3 per cent, the highest of all sectors.
• The decrease in productivity was due to an increase in both inputs and outputs, however inputs increased by 3.7 per cent while outputs increased by 6.1 per cent. In the last 10 years, there has been no change in the average annual productivity, while all other sectors have increased. Outputs have been lower than inputs for much of the last 15 years resulting in low productivity.
• Productivity of NRC was at its strongest prior to the recession, then dipped to its lowest level in 2009. This sector would have been affected strongly by the recession that started in 2008 and lasted through most of 2009. These challenging economic times will make it difficult for companies to make proportionate savings across all inputs, especially with labour being a relatively high component. Consumers find it easier to cut on this form of spending on food. During periods of economic downturn it is likely that consumers will make savings through eating out less and switching to home cooking.
• In 2017, NRC contributed 33 per cent to Gross Value Added of the food chain beyond the farm-gate.

5. Benchmarking the UK food chain against the wider economy

An estimate of total factor productivity in the wider economy is calculated for comparison purposes from the same data sources as the food chain using the same method. This measure does not cover the full economy but rather non-public sector industries that are covered by the Annual Business Survey. Financial services are the largest sector not included in the measure. In 2017 the productivity of the food chain increased by 1.5 per cent while the wider economy decreased by 0.2 per cent. In the 10 years prior to 2017, the average annual growth rate of the food chain was 0.4 per cent whereas the wider economy’s average annual growth rate was 0.2 per cent. For the last 10 years, the food chain has had a higher productivity than the wider economy, except for 2014 and 2015.

6. Background notes

6.1 TFP calculation

The method incorporates the inputs and outputs that are associated with monetary transactions but does not incorporate external effects on society and the environment. TFP differs from labour productivity by factoring in capital consumption. This calculation covers labour, capital and purchases while output is the volume of sales. TFP is measured only in the form of changes as the change in the ‘volume of outputs’ divided by the change in ’the volume of inputs’. The series is annually rebased and chain linked. Inputs are measured in the form of labour, capital and purchases. Purchases (mainly food but also energy, water and other consumables) dominate the inputs in all sectors.

6.2 Contribution of inputs

Category	Capital	Purchases	Labour
Catering	8	57	35
Retail	4	78	18
Wholesale	1	92	7
Manufacturing	4	81	16

6.3 Factors influencing total factor productivity

In economic theory, Total Factor Productivity (TFP), also called multi-factor productivity, measures the proportion of output not explained by traditionally measured inputs of labour and capital used in production. Increases in total factor productivity reflect a more efficient use of inputs and TFP is often taken as a measure of long-term technological change or dynamism brought about by such factors as technical innovation. Explaining year to year changes in TFP is not straightforward as there is no single factor that can explain changes in TFP behaviour.

There are several macro and micro economic factors, which together can help to understand patterns in the TFP behaviour:

Changes in technology

Factors of production typically include land, labour, capital and natural resources. These inputs are used directly to produce a good or service. Technology, on the other hand, is used to put these factors of production to work. A firm doesn’t purchase additional units of technology to feed into the production process in the same way that a firm might hire more labour in order to increase output. Instead, the technology available in a particular industry or economy allows firms to use labour and capital more or less efficiently. Advances in technology alter the combination of inputs or the types of inputs required in the production process and that usually means that fewer and/or less costly inputs are needed. Innovation is the driving force behind these leaps in efficiency.

Macroeconomic factors

Economic stability (e.g. inflation, interest rates, and exchange rate), levels of taxation, fiscal and monetary policies can lead to changes in the level of output produced in the economy. For example, fluctuations in commodity prices resulting from increased/low levels of inflation or exchange rates can cause higher/lower inputs prices and subsequently affect the production cost and the TFP. Economic shocks and cyclical movements of the business cycle (intrinsic periods of recession to recovery) can also account for changes in total factor productivity.
Overall openness to international trade and capital mobility are expected to boost productivity growth. International trade spurs competition –which leads to innovation –as well as serves as a channel for technology diffusion amongst nations. Generally, openness to capital flows (Foreign Direct Investment) is associated with technology diffusion and knowledge transfers, which in turn boost productivity growth.

Human Capital

Labour skills positively affect productivity because of its inherent contributions to capital productivity, innovation and technological change. In addition better labour skills may also increase the capability of an economy to benefit from externalities created by international trade and capital flows.

Institutions

Institutions and the overall legal framework of an economy shape the incentives for both factor accumulation and innovation and therefore play an important role in fostering technological change as well as improving the overall allocative efficiency of factors of production. Furthermore, technical change is significantly impacted by innovation through public research and improved human capital through education and health care access.

7. Uses and potential uses of this data

Defra use TFP in the food chain beyond agriculture as a measure of how well the UK food industry beyond agriculture is improving its productivity and thereby on course to be competitive in the future. Improving the productivity and competitiveness of food and farming businesses, while improving the environment, is a priority for Defra. Domestically a more competitive, profitable and resilient farming and food industry is needed. As the UK economy recovers, this sector, like all others, needs to maximise its potential for sustainable growth, maintain and increase its chance of securing European and global trading opportunities, and meet society’s needs. We also need a basic level of resilience against changing environmental conditions, price fluctuations, financial uncertainty and food availability.

The Food and Drink Federation use this data to communicate to its members (by tracking the industry’s progress and promoting the sector) and they make this information available on their website. Food and drink businesses can also use this data to track progress of the industry in general but this measure is not comparable with competitiveness measures applied to individual businesses and cannot be used to benchmark their own performances.

This measure is not directly comparable with the general calculation used by the Office for National Statistics to measure whole economy productivity. To enable a comparison with the wider economy we calculate TFP growth in the wider economy using this calculation, i.e. data from the annual business survey. It is limited to coverage of the economy by the Annual Business Survey. The Annual Business Survey is the main structural business survey conducted by the Office for National Statistics. Prior to 2009 it was known as the Annual Business Inquiry - part 2. It collects financial information for about two-thirds of the UK economy, covering agriculture (part); hunting; forestry and fishing; production; construction; motor trades; wholesale; retail; catering and allied trades; property; service trades. The financial variables covered include turnover, purchases, employment costs, capital expenditure and stocks. Further details on the survey are at: Annual Business Survey – ONS

The original research this statistics release is based on was published in May 2006 and is available here: UK Food Chain Productivity research. Total factor productivity of agriculture is published in Agriculture in the UK Chapter 5. Data up to 2017 is available in Chart 5.1.

8. Glossary

8.1 Economic Definition of the food sector

The UK food sector is defined in terms of the standard industrial classification (SIC 2007) as food manufacturing, food wholesaling, food retailing and non-residential catering:

Category	SIC codes
Food and Drink Manufacturing	10 + 11
Food and Drink Wholesaling	46.3 (excluding 46.35) + 46.17
Food and Drink Retailing	47.2 (excluding 47.26) + 47.11 + 47.81
Non-Residential Catering	56

The deductions are to remove non-food items as far as possible.

8.2 Food and Drink Manufacturing

The sector comprises of nine main categories including processing and preserving meat, dairy, fruit and vegetables, oils, bread, biscuits and cakes, and confectionary. Animal feed manufacturing is included, covering both farm animal feed and pet food, and representing 8% of total turnover in food and drink manufacturing in 2017. The drink manufacturing sector includes alcoholic beverages and soft drinks and mineral waters.

8.3 Food and Drink Wholesaling

The sector consists of the buying, storage and reselling of food either manufactured or freshly produced. Wholesale of tobacco products is not included.

8.4 Food and Drink Retailing

The sector is defined as the sale of food within both non-specialised stores (e.g. supermarkets) and specialised stores such as butchers and bakers.

8.5 Non-residential Catering

(NRC) consists of restaurants and bars involved in preparation and serving of food, alongside canteens and catering services. Hotels are not included.

8.6 Gross Value Added (GVA)

GVA is the difference between output and intermediate consumption for any given sector / industry. This is the difference between the value of goods and services produced and the cost of raw materials and other inputs which are used up in production.

8.7 Inputs

Inputs are labour (total hours worked), capital expenditure and purchases (of goods materials and services).

8.8 Outputs

Output is Turnover (volume of sales of products.).

These estimates are produced twice yearly. Most of the data is sourced from the Annual Business Survey (ABS), which is produced by the Office for National Statistics (ONS). The ONS release the ABS provisional estimates normally around November and the revised estimates are released around June. Data in this release comes from the Annual Business Survey published in November 2018, The Annual Survey of Earnings and Hours published in October 2018 and Capital Stocks: Consumption of Fixed Capital published in August 2018. The next TFP update will be in July 2019.
