  ABSTRACT: This study aims to assess the impact of technological specification and innovation dynamics in Schumpeterian perspective on the technological performance (innovation) of firms. Using an original data construction, our empirical analysis is carried out with patent and survey databases on French firms. We classify the various possible determinants of innovation into two groups of variables; firm-specific variables and sectorial-specific variables. We utilise patent data from European Patent Office (EPO) database (classified in 30 technological classes), survey of the R&D resources and, firm’s surveys in French (EAE) for French firms for the period 1993-2001. The results of our count data models show that entrepreneurial activity increases the innovation output and the sectorial-specific variables have an impact on patent application.
