The Effects of Industrial Systems on Technology Adoption Joung Yeo No Yonsei University
Industrial Systems in TechnologyAdoption • The advantages of geographical agglomeration on knowledge spillovers and technology adoption • Not only the size of cluster matters • Does the organization of economic activities within a cluster matter as well?
What is Industrial Systems? Relationship between the internal organization of firms and their connections to one another and to the social structures and institutions of their particular localities Industrial system has 3 dimensions: • Local institutions and culture • Industrial organization • Corporate organization
Effect of Industrial Systems on Technology Adoption • The innovativeness of a region depends not only on the size and density of cluster, but also on how the economic activities within a cluster are organized. • Silicon Valley vs. Boston’s Route 128 (Saxenian, 1994) → Silicon Valley - open, flexible and entrepreneurial environment with many small-, medium-sized plants. - decentralized regional network-based system → Route 128 - Rigid and hierarchical with few dominant players. - independent firm-based system
The Objectives 1. How the regional industrial system affects technology adoption by plants 2. How plants respond differently to geographical agglomeration and regional industrial system depending on their internal resources and information networks
Related Literature Three relevant strands: 3. Work on the effects of industrial systems (Saxenian 1996) – Descriptive studies on Silicon Valley and Route 128 1. Work on the sources of agglomeration (Rosenthal and Strange 2001; Dumais, Ellison, and Glaeser 2002; Holmes 2002). • Work on other types of knowledge spillovers – Patent citations • (Jaffe, Trajtenberg, and Henderson 1993).
Do industrial systems affect plants’ decisions to adopt technologies?
Hypotheses H 1a: Adoption of advanced manufacturing technologies is more likely with an increase in employment at small plants in the region. H 1b: Adoption of advanced manufacturing technologies is more likely with an increase in employment at plants that are single-plant firms in the region.
Hypotheses H 2a: The effect of regional industrial system is greater for small plants than for large plants. H 2b: The effects of regional industrial system is greater for single-plant firms than for plants that are part of multi-plant firm.
Hypotheses H 3a: The effect of knowledge spillovers from prior adopters is greater for plants with less internal resources. H 3b: The effect of regional agglomeration is greater for plants with less internal resources. H 3c: The effect of knowledge spillovers from prior adopters is greater for plants that are single-plant firms. H 3d: The effect of regional agglomeration is greater for plants that are single-plant firms.
Main Finding I. Technology adoption is facilitated by the industrial system that are characterized as follow: • That are agglomerated with small plants • That are agglomerated with single-unit plants • That are agglomerated with plants that are similar • Plants with the following characteristics are more likely to benefit from the regional agglomeration and knowledge spillovers: • Plants that are small • Plants that are single-unit
DATA 1993 Survey of Innovation and Advanced Technology • Unique, confidential, proprietary data • Adoption of 22 advanced manufacturing technologies at the plant level • 1902 plants covering an entire manufacturing sector across Canada • Panel nature: years of use for each technology (1984-1993) → Panel of 3 intervals: 1984-1986, 1987-1989, and 1990-1992.
DATA (Cont’d) • Annual Survey of Manufactures • - Collects information on the universe of manufacturing plants in Canada. • National Input-Output Table • - Input supply and output demand relationships among industries • Census of Population • - Demographic information → Sample size: 1,902 plants, 22 technologies, 3 time periods ⇒ 106,188 obs.

Functional and Industrial Dimension 1. Industrial Dimension • based on industry classification 2-digit (22) and 3-digit (169) SIC 2. Functional Dimension • based on similarities in input purchases
A measure of ‘related’ industries: I develop a measure of ‘related’ industries based on the similarity of input purchases across industries. ρij = correlation between industry i and industry j in terms of pattern of input purchases For each industry i, all other industries are classified into three groups: Similar industries : 0.5 ≤ ρij Moderatelysimilar industries: 0.2 ≤ ρij < 0.5 Different industries: ρij < 0.2
