This paper analyses industrial structure in Canada over the period 197
1 to 1991 using Statistics Canada's input-output model and explores mo
re closely the role played by the ''new economy'' industries, those in
dustries where innovation through the uses of knowledge, technology, a
nd skills is the key to generating growth. The conclusions indicate th
at Canadian industrial structure is becoming increasingly knowledge-ba
sed and technology-intensive, with competitive advantage being rooted
in innovation and ideas, the foundations of the new economy. While in
the past domestic demand mainly influenced the growth of industries, t
rade is becoming much more important. High-knowledge industries in the
tradable sector seem to have benefited the most from export performan
ce; import competition has hastened the relative decline of low-knowle
dge industries.
