"It is difficult to distinguish between the design
skills and technologies used in these (electrical
and electronics) industries. Similarly, many
inputs such as printed circuit boards, electric
accumulators, capacitors, diodes, transistors and
electronic microcircuits are common to all of
these industries. There are also common
production processes. This commonality also
extends to the use of the goods. A programmable
controller and a small computer might equally be
used to control motors or other equipment. Final
goods such as computers or telecommunications
equipment generally include power electronics
circuits. The rapid diffusion of technologies is
strengthening the relationship between these
industries, viewed both from the consumption and
production perspectives.
It is likely that this trend will become more
marked over time as, for example, solid state
technology is increasingly used for functions now
served by electro-mechanical devices (for example,
in switching). As a result, the distinction
between technologies used within different parts
of the electrical and electronics industries can
be expected to become even more difficult to
distinguish.
As a further complication, the assistance regimes
existing in related industries will affect the
final price of their products (for example, the
relative prices of electro-mechanical relays
compared to the price of programmable controllers)
as well as the relative attractiveness of each as
investment choices. In attempting to establish an
appropriate assistance regime for the power
electronics industry, it is important to recognise
the assistance regimes in related industries.
Differences in levels of assistance will disturb
consumption patterns and the ability of a
particular industry to draw or hold resources
relative to related industries."
