Background
…andabafflingproduc/vitypuzzle!
High Growth Firms and Productivity - Evidence from the United Kingdom, 2014, Du Jun and Yama Temouri, Small Business Economics, 44:123–143
Decomposing UK Aggregate Labour Productivity and Growth, 1998-2013, 2015, Du Jun and Karen Bonner, ERC Report
Problem 1: Fast growth firms definition High growth firms, in
employment (OECD, 2007)
High impact firms
Growth heroes (Du and Bonner
2015)
Top performers
Millennium 2000 firms (Hart et al 2016)
High growth entrepreneurs
Gazelles
High employment growth firms
(Clayton et al, 2013)
High growth firms, in value
Objective 1: To understand the differences in fast growth definitions and their implications
Problem 2: Limited predictability of fast growth firms Growth persistence is not at firm level, but at regional level• The predictability of fast growth
episodes remains limited
• firm growth is typically highly discontinuous and high employment growth is not persistent among firms
• Recent research on growth persistence beyond single firms – at regional level Objective 2: To understand what
it means for a region to have more fast growth firms

Definition matters!
• Applying policy on different type of fast growth firms will affect different business populations which will result in different outcomes.
• Way forward: Growth Super Heroes + OECD HGFs
Employment-based high growth firms generate lots of jobs but have mixed productivity records
Productivity-based high growth firms have mediocre job creation records but show productivity superiority

Regional and industrial externalities
• Role of location factors (both in the literature of economic georgrphy and HGFs)
• Region-industry perspectives – Regional effects examined in relation to the industrial portfolio and
activities
– Knowledge spillovers within (MAR externalities) and across industries (Jacob, 1969)
– Localisation externalities: non-knowledge spillovers
– Urbanisation externalities
Data Main Data Source: • Business Structure Database 1997-2013 by the UK Data Service
quasi-totality of UK firms about industrial classification, postcode, employment and turnover.
• Total final sample of 36,601,155 observations, 6,253,704 UK Manufacturing: 500,000 firms, 2,800,000 observations; Professional services: 2,300,000, 11,200,000 observations
Industrial and Regional Data: • Region-industry employment, productivity, net entry rate and agglomeration
index (BSD database);
• ONS input-output tables for product and services supply and demand and gross value added (GVA) for all sectors at the 2-digit level in the UK;
• R&D intensities at the regional and industrial level from UK Innovation Survey database (CIS);
• Location and size of science parks in the UK are collected from the UK Science Park Association (UKSPA) website.
Geographical Distribution of fast growth firms
OECD employment-based High Growth firms: Relatively more evenly distributed across the country.
Productivity-based Growth Super Heroes: Agglomerated around urban and highly populated areas.
Region-industrial Distribution of fast growth firms
OECD employment-based High Growth firms: Prof. services, food, publishing and media, environmental goods, non-metal products (more labour-intensive sectors)
Productivity-based Growth Super Heroes: Machinery, automotive, transport equipment (more capital intensive manufacturing sectors)
Methodology
Estimation: manufacturing and professional services sectors, large vs small, old vs young enterprises and in low and high-tech sectors. Panel FD-fixed effects model.

Finding 3: Regional distribution of externalities
EMPLOYMENT: negative effect in peripheral areas (Scotland and Northern England), positive in urban and populated areas (London, South-East, Birmingham, Northern Powerhouse)
PRODUCTIVITY: positive effects on productivity where negative impact on employment growth: rural and sub-urban peripheral areas
Finding 4: Region-industry distribution of externalities
• Negative on Employment: automotive, fuels, optical instruments, textile and apparel • Positive on Productivity: prof. services, chemicals, computer industry • Largest spillovers in peripheral areas: Wales, NI, North-East England
Finding 5 – Geographic Externalities
1. Postcode Agglomeration same as industrial externalities:
- negative on employment - positive on productivity
2. FG Gravity Force
1. FG Postcode Agglomeration
2. FG Gravity force: FG Positive demonstrative and market-creation effects on both employment and productivity growth

Summary and discussion Key message: Beyond job creation and productivity improvement within their own organizations, high growth firms have externalities to other firms in the region, within and across industrial sectors. Industrial externalities of fast growth firms: Horizontal effects:
• Competition-led efficiency improvement with positive productivity spillovers
• Sign of reallocation of inputs to more productive (and likely more innovative) firms within sectors
• Competition-led crowding out effects for skills and labour Vertical effects:
• Increased demand for services and products along supply chain – positive market creation effect
• Improved productivity and efficiency in upstream sectors – knowledge spillovers effects
• Competition-led crowding out effects for skills and labour in the upstream sectors
Summary and discussion (conti)
Regional disparity: • Advantageous urban areas in labour and skill provision • Interestingly, the areas of more high growth incidences are not
necessarily those which benefit most from it Geographic externalities: Local Agglomeration (Postcode level)
§ Competition-led efficiency improvement with positive productivity spillover § Competition-led crowding out effects for skills and labour
Gravity Force § Demonstration effects and new local demand for services and products
with positive externalities on both employment and productivity growth
