Abstract
This paper discusses the sectoral differences in the innovation activity in Brazilian small industrial firms. It starts with the hypothesis, originally developed by Pavitt (1984), that there is sectoral heterogeneity in the generation of innovations process, regarding the knowledge sources and the cooperation relationships as well as the results in terms of rates of product and process innovation. In this work we use data from the Pesquisa de Inovação Tecnológica (PINTEC) released by the Instituto Brasileiro de Geografia e Estatística (IBGE) for the year 2008. By using a tabulation specifically developed for this study, we present the data displayed by firm size and sector. The results confirm the main hypothesis and show that the innovative behavior of small firms should be apprehended in the light of the sectoral specific features that underlie the innovation activity, results which are consistent with the propositions of the literature.
