摘要：In today’s competitive scenario, regional growth is largely associated with the performance of innovation systems, the intensity and effectiveness of interactions between the different actors involved in the generation and dissemination of new knowledge and technologies. In this direction, this paper aims to analyze the interactions between agents of the Sugar and Ethanol Industry in the state of Alagoas, across the three dimensions of the Sectoral Innovation System (organizations, institutions and technologies), proposed by Malerba (2002). In constructing the objective of this article, we conducted an exploratory-descriptive through secondary data and the application of questionnaires to seventeen companies’ sugarcane in the state. The analysis of data occurred by using nonparametric statistical techniques: Coefficient of Concordance, Kendall (W) test and the Kruskal-Wallis H, considering a significance level of 0.05. The results pointed to the confirmation of the existence of positive interactions between the three dimensions examined (organizations, institutions and technologies), but to a lesser extent, to the last. There are two additional aspects: the company submits an interaction between universities and research centers, and much of the technological advancement of this industry is coming from public and private partnerships. It is noteworthy also that the R & D effort is focused on genetic improvements to the field and process innovations that improve production efficiency. As an additional contribution, this article describes a review and practical application of the phenomenon of innovation and its links with the sectoral systems.
