Dynamic technological specialization,aggregated convergence and growth

This paper focuses on the contribution of dynamic technological specialization to aggregated growth and convergence. Certain theoretical approaches (Structuralism) maintain the view that being specialized in ‘correct’ technologies helps to achieve: i) sustainable rhythms of long-run growth; ii) accelerated catching up and higher rhythms of convergence in delayed countries. Using an endogenous growth model for a 23 countries sample between 1980 and 2010, the work contrasts those hypotheses by using static and dynamic approaches for technological specialization in comparison to other technological variables. Empirical results do not confirm that any ‘good’ specialization matters to growth and convergence at an aggregated level, neither under static nor dynamic approaches. The key elements to aggregated convergence and growth are more linked to spillovers of technological diffusion and to country-specificities (technological capabilities and capacities, domestic technical efforts, national innovation systems, industrial innovation processes, etc.) as it is pointed out by catching-up theories.
