Recherche-développement et performances des entreprises : une étude économétrique sur données individuelles

  • Jacques Mairesse
  • Philippe Cunéo

[fre] L'étude porte sur un échantillon de 390 entreprises grandes et moyennes des secteurs de la Chimie, de l'Electronique et de la Mécanique, qui font ou ne font pas de recherche-développement. Dans une première partie, on compare directement les caractéristiques et performances des entreprises de recherche et sans recherche ; cette comparaison montre que les différences entre ces entreprises ne sont pas aussi tranchées qu'on pourrait l'attendre. Dans une seconde partie, on compare plutôt les dépenses de recherche-développement des entreprises et leurs investissements physiques, en se fondant sur un analyse économétrique en termes de fonction de production. Les résultats concordent assez bien avec l'idée que la recherche-développement constitue un capital comparable au capital physique du point de vue de sa productivité et de sa rentabilité. Un examen de la robustesse de ces résultats permets d'en préciser la signification ; il conduit à aborder le problème de la divergence des estimations en coupe et en série temporelle, et il pose la question de la complémentarité entre qualification du travail et capital. [eng] Research-development and firm performance :. An econometr1c study on individual data. Jacques Mairesse, Philippe Cunéo. The study is based on a sample of 390 large and medium sized firms from the Chemical, Electrical equipment and Machinery industries, which either do or not invest in Research and Development (RD). In the first part, R-D and non-R-D firms are directly compared, the results showing that the differences in caracteristics and performance between them are not as sharp as one could have expected. In the second part, the comparison rests instead on the R-D and the physical investment of the firms, based on a production function approach. The econometric estimates agree rather well with the idea that R-D capital has a similar productivity and profitability to that of the physical capital stock. An analysis of the robustness provides a better underrtanding of the meaning of the results ; it brings into focus the problem of the discrepancy between the cross-section and time-series type of estimates ; it also raises the question of the complementarity between tobor qualification and capital.
