Résumé
La relation productivité — R&D dans les industries manufacturières du Québec est examinée dans le cadre d’un modèle inspiré par Grilliches, Scherer et Terleckyj. Les effets indirects de la R&D associés aux relations interindustrielles et aux investissements sont calculés pour 1971-1982. Les taux de croissance de la productivité de travail sont étroitement associés aux variations des dépenses de R&D directes et indirectes, ainsi qu’à la variation du ratio K/L. Le financement public en subventions fédérales à la R&D semble exercer un effet plutôt négatif sur la productivité.
Abstract
The R&D — Productivity relationship in Québec's manufacturing industries is examined in a framework of growth accounting pioneered by Grilliches, Scherer and Terleckyj. The indirect effects on productivity of R&D executed by upstream suppliers are calculated for 1971-1982 period. The labour productivity growth rates are closely correlated with the growth rate of direct and indirect R&D expenses and with the growth rate of capital — labour substitution. The results suggest that the indirect R&D has a more important and statistically more significant effect on productivity growth than the direct R&D. Federal subsidies to R&D seem to have a negative rather than positive effect on productivity growth.
