Abstract
[Autom. eng. transl.] The interaction between the sectoral composition of the economy, the scientific and technological research activity of companies and universities and the activity of large companies is considered a crucial factor of development in advanced countries. This work studies the relationship between the dynamics of international technological specialization, the expansion of markets and profit opportunities, the accumulation of technical and scientific knowledge and, finally, the market structure. The work uses R&D and export data, patent applications and citations to the European Patent Office for six countries (United States, United Kingdom, Italy, Japan, France, Germany) in the period 1981-1994 for 135 technological classes in three sectors industrial (chemical, electronic and mechanical). The econometric analysis, using GMM estimates for dynamic panels, indicates that the international technological specialization is persistent and positively influenced by the relative effort of companies in R&D, by inter-sectoral knowledge spillovers within countries and by the quality of research produced by the universities and public research centers. The magnitude of the estimated relationships differs between the three industrial sectors. Furthermore, this work shows that the concentration of innovative activities can have a negative effect on international technological specialization.
