For this the study was based on a sample of 617 MSE distributed in 6 cities of the State of Piauí. The data were collected through the application of the Innovation Radar. Statistical techniques of descriptive, exploratory and inferential nature were used. The results showed that MSE have innovation capacity between "Little Innovative" and "Occasional Innovative", due to the greater expressiveness of organizations and marketing innovations, and that the average and the distribution of innovation are the same among MSE analyzed.
