Inter-industrial technology diffusion : a macro analysis of technical change in the Canadian economy.
It is now well recognised that the improvement of the economic performance
and the restructuring of industries depends not only on the generation (or
production) of new technology but also on the rate and level of diffusion of
technology throughout the economy.
This thesis presents an inter-industrial analysis of the effect of
diffusion of technological change on the Canadian economy. To do so, it
describes the diffusion of information using Canadian patent statistics
potential sector of manufacturing and use. It then uses the patent matrices
as 'support' matrices to transform R&D data by industry of origin into R&D
data by industry of use to calculate the direct and indirect R&D inducement
based on a static input-output model. Finally it is used to estimate the
impact of own R&D and R&D spillover on total factor productivity growth,
differentiating the R&D spillover according to various 'support' matrices and
different 'gestation times'.
The empirical results confirm: i) the existence of an important interindustrial
flow of innovation, ii) the existence of a 'common core' of industry
at the source of technological change, as well as the importance of using
industries as 'core innovative' industries, and iii) the emergence of service
industries as a strong user of capital goods. It also concludes that i) the
scale and structure of the external trade has an impact on the R&D
inducement of all industries, ii) innovative activity has a positive and
significant effect on productivity growth and iii) the rates of return in R&D
spillover are found only after 8 years of 'gestation time'.
