Abstract: [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).
