[eng] Skill bias: an econometric analysis at the firm level. . Over the last 20 years the structure of firms' employment has moved towards more skilled personnel while unskilled workers have faced a high and persistent unemployment. The purpose of this paper is to test the hypothesis of a skill-biased technical progress. We introduce three new features. First, we estimate our model at the firm level. Second, we distinguish 5 innovation types, that allow fora decomposition of the skill bias. Last, firm level innovation is endogenous. [fre] Le biais technologique. Une analyse économétrique sur données individuelles. . Sur les vingt dernières années, la structure de la main-d'œuvre des entrepri­ses s'est déformée au profit des personnels les plus qualifiés, alors que la main-d'œuvre non qualifiée a dû faire face à un chômage élevé et persistant. L'objectif de cette étude est de tester l'hypothèse d'un progrès technique biaisé en faveur de la main-d'œuvre qualifiée. Elle présente trois originalités. Premièrement, les estimations sont réalisées au niveau de l'entreprise. Deuxièmement, nous mesu­rons le progrès technique par cinq types d'innovation différents qui permettent de décomposer le biais technologique. Troisièmement, l'innovation est endogène.
