Effets des innovations technologiques sur l'emploi industriel : essai d'analyse à partir du cas tunisien

Abstract : The purpose of this thesis is ti determining the effects of technological innovations diffusion on employment in Tunisia. First, the empirical approaches adopted show that, in the short run, the effects on employment are positive, but they are negative in medium and long runs. If this result is not specific to the reference sample used in this research and to investigated period, the Tunisian context seems to contradict the theoretical predictions. This result could affirm the fact that Tunisian economy remains a passive consumer and a small producer of technological innovations. This investigates the absorptive capacity of the Tunisian industry and the efficiency of learning process. The short-run positive effect, on the other hand, is explained by the complementary of capital and labor. Then, we are interested to the effect of technological innovations diffusion on industry's labour demand by skill. The econometric research suggests the existence of skill-biased technical change that favour the industries demand of managers. These later are supposed the most skilled-labour. In addition to this effect, they complement the capital rather the manual workers, who are supposed unskilled-labour. We show also a strong correlation between the job flows (creations, destructions) and the different channels of technological diffusion. Finally, we attempted to evaluate the effective role of technological innovation diffusion in addition to local industrial structure (diversity, specialization and competition) in the regional development of employment. The econometric research shows that competitive environment (Porter externalities) are the diversity of industrial activities (Jacobs's externalities) are favorable to local development. The result also prove that technological innovation may be having a positive global effect on regional employment.
