There are wide variations between the developing countries in the capa
bilities of their enterprises to import, utilize and improve upon indu
strial technologies. It is important for the purposes of industrial po
licy to understand why these differences exist and how industrial capa
bilities may be improved. This article presents the findings of recent
research into the nature of capability development and the role of go
vernment policies in promoting such development. The process of becomi
ng efficient in industry is very different from the usual textbook por
trayal, in which firms costlessly access and absorb new technologies.
In reality, there is a long and uncertain learning process involved, d
iffering with the nature of the technology, the efficiency of factor a
nd product markets, and the provision of various technological informa
tion and services from the infrastructure institutions. There is a wid
espread risk in developing countries that all these markets suffer fro
m failures: the scope for technology development policies rests on the
need to remedy these failures. The experience of the most successful
newly industrializing economies (NIEs) suggests that well-designed int
erventions, both selective and functional, are needed to promote techn
ology development. Experience clearly shows the dangers of government
failure, but it is necessary to retain a large role for the government
if industry is to succeed. The pattern and implementation of interven
tions have to be very different. This article points out the outlines
of economically desirable interventions.
