“efeito de estrutura”
A composição sectorial da economia portuguesa tem evoluido no sentido de um peso maior do sector dos serviços. Contudo, o sector da
indústria transformadora
é ainda mais importante em relação a muitos países da OCDE, e a distribuição do emprego pelos sectores produtivos portugueses permaneceu estável até ao início dos anos noventa, assim como fortemente dominada pelos sectores:
– –
têxtil calçado
–

TECHNOLOGY INTENSITY of INDUSTRIES
Concept:
–
measures the effort put into R&D activities within each industry method 1: Direct Technology Intensity:
–
ratio between the expenses on R&D activities output (typically gross output or value added) and a measure of
TECHNOLOGY INTENSITY of INDUSTRIES
method 2: Considering second-round gains
–
the R&D embodied in the output of an industry includes the R&D effort realized by that industry but also the R&D embodied in the intermediate goods it acquires from other industries method 3: Taking into account the cumulative nature of R&D
–
The technology intensity of an industry after several years is the sum of the technology intensity of that industry for the all the years considered
OECD INDUSTRIAL SECTORAL TAXONOMY ACCORDING TO TECHNOLOGY INTENSITIES
The OECD (1996) suggests a breakdown of industries into four groups, according to their level of technology intensity:
—
High Technology Intensity industries
—
Medium High Technology Intensity industries
—
Medium Low Technology Intensity industries
—
Low Technology Intensity industries The classification of industries into these four groups is roughly the same for every OECD country using whichever measuring methodology.

Pavitt ´s formulation
Purpose: to describe and explain sectoral patterns of technical change Data: UK firms between 1945 & 1979 Concept: Technological knowledge is specific to firms and applications, cumulative in development and varied amongst sectors.
Original Neoclassical formulation • New technology instantly diffuses across capital.
• Make exogenous the production of technology and innovations.
• Do not reflect the variety of the sources.
Pavitt ´s formulation • Three part taxonomy based on firms: a) Supplier dominated b) Production intensive c) Science based •Make endogenous the production of technology and innovations.
•Technical change is largely a cumulative process specific to firms.
Analysis of PAVITT
´
s data
Compare sectors in terms of: The sectoral sources of technology used in a sector; The importance of intramural and extramural knowledge sources, and of product and process innovation (institutional sources and nature of the technology) ; The characteristics of innovating firms: their size and principal activity.
Institutional sources of main knowledge inputs 7% Public technological infrastructure 34% Other industrial firms 59% Within the innovating firms themselves Most of the knowledge applied by firms in innovations is not general purpose and easily transmitted and reproduced, but appropriate for specific applications and appropriated by specific firms.
Characteristics of innovating firms: size, technological diversification, patterns of production and use of innovations Innovating firms principally in electronic and chemicals, are relatively big, and they develop innovations over a wide range of specific product groups within their principal sector, but relatively few outside.
Firms principally in mechanical and instrument engineering are relatively small and specialized, and they exist in symbiosis with large firms, in scale intensive sectors like metal manufacture and vehicles, who make a significant contribution to their own process technology.
In textile firms, on the other hand, most process innovations come from suppliers .

Indicators such as R&D intensity or patent-counting fail to appreciate the innovative capability of most traditional industries: technological change in fact is mainly based upon learning-by-doing and tacit knowledge rather than conventional R&D activities.
Traditional Industries vs.
High-Tech Industries Accumulation of technological knowledge Technological change is intense and rapid European industries seems to fall into the new category of
skill intensive
industries (Pavitt -1987).
Skill-intensive industries (SII) characteristics are: -Small size firms -High levels of regional concentration -High levels of wages -Low levels of capital intensity -Specific nature of technological change
knowledge.
localized technological
Aspects that play a major role in SII as source of technological change: -Internal organization of companies -Structure of internal labor markets -The close interaction between changes in process and products in terms of design.
- The creation process of firms and the accumulation of tacit knowledge.
Technological knowledge : Tends to be highly localized WHY ?
-Relies upon a continuum of specifications of different forms of knowledge: ►
Generic and Scientific Knowledge
(public good) ►
Tacit Knowledge
(result of lengthy learning processes, idiosyncratic and specific to the business of the firm) highly - It is costly to use elsewhere (switching costs) - Highly impure public good
Why is this Tacit Knowledge so
firm specific
?
Technological knowledge is embedded in the “circumstances” in witch the firm operates The traditional distinction between new technologies and existing technologies appears much weaker (relevant search costs) The generation of technological knowledge is the result of a mix of production, learning and communicating, of which R&D is only a part
Localized Knowledge Deduction from general principles Experiment, learning-by-doing, learning-by-using.
Codified Knowledge
Firms rely upon varying mixes of tacit and generic knowledge in order to generate localized technological innovations.
But more on tacit k. or more on generic k.?
Depends … -The amount of resources devoted to implementing the accumulation of tacit knowledge by each agent in the system -Its receptivity to technological knowledge generated by third parties -The properties of the system in terms of connectivity and distribution of receptive agents
New technological change emerges also from the daily interaction of learning firms among themselves and with other scientific institutions
What are the main incentives to invest on learning-by-doing or R&D activities?
“
Firms are pushed to introduce technological innovations by pressure of demand
” (Rosenberg, 1974) Increase rate of growth of output Investment on learning-by-doing and R&D activities Growth of labor productivity Technological Innovation Lower average unit costs

-
Time span of six years (1988-1994)
-
In these years, the industry recovered from the crises of the late 1980s and experienced a fast growth fueled by the demand for capital goods after 1991, with an increase in added value and TFP
The Faster is the output growth The larger are the stimulations to capitalize on acquired tacit knowledge The faster is the rate of introduction of localized technological innovations Hence Makes possible Increase TFP Generation of new localized technological change Empirical Evidence Recursive cycle of growth Increase market share and output Reduce market prices And

•“ With some notable exceptions, the regional developmment debate in Europe has been dominated by
exogeneous models
to such an extent that development tends to be conceived
as something that is introduced to
