Investissements immatériels, productivité et qualifications
[fre] Investissements immatériels, productivité et qualifications. . Les changements et les différences de productivité et de structure de qualifications des entreprises sont-ils liés à leurs investissements immatériels ? L'objet de l'étude est d'éclairer ces questions en tirant parti principalement d'informations sur les effectifs de quatre catégories de personnels spécialisés : informaticiens, électroniciens, chercheurs et chargés d'études. Menée sur de grands échantillons d'entreprises des secteurs industriels et des services et commerces, pour les deux périodes 1986-1990 et 1990-1994, elle met en évidence des liaisons significatives et fortes dans la dimension transversale des données (corrélations interentreprises), mais fragiles et faibles dans leur dimension longitudinale (corrélations intra-entreprises). [eng] Intangible investments, productivity and skills. . Are the changes and differences in firms productivity and skill composition related to their intangible assets? This study tries to answer by mainly taking advantage of information on the numbers of four categories of specialized workers: computer, electronics, research and analysis related staff. Based on large samples of French manufacturing and services firms for the two 1996-1990 and 1990-1994 periods, it finds significant and strong relations in the cross-sectional dimension of the data (betwen firms correlations), but only fragile and weak ones in the time-series dimension (within firms correlations).
