Local ClusterConcepts, Facts and Theory

The Topic Concepts Theory Facts

Thomas Brenner

DIMETIC October 2007

Why Is This Topic Relevant ?

Scientific perspective: Spatial distribution of industries Success of certain regions

Policy perspective: Why are there differences between regions ? How can unsuccessful regions be made

successful ? How can clusters be established ? How can they be made more successful ?

How Is This Topic Treated in the Literature ?

Case studies: Study of emergence Examination of success

Theoretical approach: Mathematical: New Economic Geography Conceptual: Various concepts

Spatial econometrics: Spatial distribution of industries Identification of clusters

New Economic Geography

Mathematical Two- or few-country models of specialisation Stability of local clusters

Simulations Local externalities: centripedal and

centrifugal forces Explanation for existence of agglomerations Spatial distribution

Conceptual Works

Discussion of one or a few important factors

Industrial districts Innovative milieux Local clusters

Various definitions Dominant definition: Porter

Learning regions, regional innovation systems etc.

Discussion of Important Factors

Common labour market, service firms and cooperation (Marshall)

Flexible specialisation (Piore & Sabel) Social networks (Becattini) Diamond model (Porter) Innovative milieux (Camagni) Learning regions (Lundvall) Spin-offs (Klepper)

Industrial Districts

Marshallian: Common labour market Service firms Spillover / Interaction

Italian: Plus: Social network

Characteristics Concentration of small firms Strong interaction Manufacturing industry

Innovative Milieux

Concentration of innovative actors This creates sometimes

Synergies through interaction Innovative atmosphere

Porter’s Diamond Model

Chance

policy

Local factors and resources

Firm strategy and competition

Related and service industries

Demand

Definition: What Are Clusters ?

Scientific: Many different concepts and definitions Common: Agglomeration of firms of one or a

few industries in a region Different additional conditions, industry and

region requirements

Policy: Some regionally interacting firms Sometimes higher requirements

Factors: What Causes/Characterises Clusters ?

Supplier-buyer linkages (ID,IM,LC) Cooperation (ID,IM) and competition (LC) Social contacts (ID) Innovations (IM) Local research (LC) Local policy (LC) Spillover/synergies (IM) Labour market (ID) Demand (LC)

Emergence vs. Success

Success How do firms benefit in clusters ? What are the mechanisms behind local

externalities ? Does not explain existence !

Emergence Why do local clusters exist ? How do they emerge ? What are the mechanisms behind the self-

reinforcement of clusters ?

Emergence of Clusters

What are the relevant dynamics and mechanisms ?

What are the relevant local factors ? How do we study these processes ?

How do local clusters emerge?

1st stage: Emergence of the market



2nd stage: Emergence of cluster




3rd stage: Stability




3rd stage: Stability

4th stage: Disappearance

Necessary conditions I

I. Sufficiently strong local self-augmenting processes

Necessary conditions II

1st stage: Emergence of the market:II. Sufficiently supportive local conditions

Market and local attractiveness

Necessary conditions III

2nd stage: Emergence of cluster:III. Sufficiently fast development


Necessary conditions

Substitutes: Different mechanisms creating self-augmenting

dynamics Different aspects of local conditions Different aspects of local developments

Complements: The self-augmenting dynamics have to be strong

enoughand

The local conditions have to be sufficiently good and

The local developments have to be sufficiently fast

Analysis of Factors and Dynamics

Measuring Regional Innovation Systems

What is a RIS? Innovativeness of regions Measurement approaches Local factors

Thomas Brenner


What is a RIS ?

Two definitions in the literature: Innovative regions

Research infrastructure Innovative firms and industries

Similar to national innovation systems All elements and interactions That contribute to innovation generation In a region

What is a RIS ?

Innovative regions How are they defined?

Case studies Innovation output, but no threshold Innovation inputs, such as R&D expenditures

or public research

What does it mean?

What is a RIS ?

System perspective Number of interacting elements With interactions like

Joint research Cooperation (more general) Flow of knowledge Flow of people Flow of money

Innovativeness of Regions

Regional Innovation Scoreboard Ranking of EU regions according to a number

of variables Human resources in science and technology Participation in life-long learning Public R&D expenditures Business R&D expenditures Employment in medium/high-tech manufacturing Employment in high-tech services European patent applications


From a presentation by Hugo Hollanders (MERIT)


What is innovativeness of regions? Total innovation output? Innovation output per inhabitant? Innovation output per R&D employee?

What does it mean?

Measurement Approaches

Usual approaches: Innovation scoreboard

Input and output variables

Total innovation output Innovation output per inhabitant Innovation output per R&D employee Knowledge production function and

production frontier Non-parametric frontier approach

Local Factors

What are the local factors that play a role for the innovation output of regions: Regression

Nations Regions Firms

Identification of Local Clustering

Which Industries show clustering ? Ignored in the literature Some discussion about low-tech industries

Where are local clusters ? Italian approach Identification according to specialisation ratio Own approach: Distribution estimation

Italian Approach

Definition of labour market areas Specialisation (share of industry’s workers) Additional conditions

Dominance of manufacturing Dominance of small and medium size firms

Results Identification of industrial districts Repeated

Specialisation ratio

Regions according to statistical office Specialisation (share of industry’s workers)

higher than 3 Sometimes additional conditions

Certain number of related industries

Results Identification of local clusters

Distribution Estimation

Exponential function:P(f) = a1

f

Boltzmann-like distribution:P(f) = f a2

f

Cluster part:P(f) = (f-a4) a5

(f-a4) if f>a4

Industries with Local Clusters

Manufacturing industries: Clustering can be proved for around 50%

For the number of workers and For the number of firm sites

Service industries: Clustering can be proved for around 30% for

each number Approach does not apply for around 20%

Problems with Location Model

Not all factors can be empirically measured What are the original factors ? What factors develop because of the

agglomeration of the industry ?

Policy approaches

Cluster organisation Network financing and promotion Monetary support for cluster activities Technology parks Improvement of local conditions

What is supported

Coordination Networking Joint innovation and research Subsidising specific locations Public research Education

Basic questions

Should policy be involved ? When should activities been taken ? Where should activities been taken ? What should be done ?

First Stage: Where Do Clusters Emerge?

1st and 2nd stage: Emergence of clusters:Sufficiently supportive local conditions


Second Stage: Will Potential be Used ?

2st stage:improve local dynamics


Third Stage: Stable Situation

3rd stage:Emergence unlikely
