In the last decades, important changes occurred at the local level of government in Brazil, associated to the transfer of competences and responsibilities to the municipalities and related to the incorporation of innovations at this level of government. In spite of an expressive number of researches with focus on these changes, there is still a lack of studies about the dissemination of public policies, innovative programs and innovations on public administration. Only recently some studies began to focus the analysis of the process by which an innovation is reproduced in another locality or, in another perspective, the process of adoption of innovations by a municipality based on an inspiration brought by similar initiatives in other localities. The purpose of this chapter is contribute to bring the theme of dissemination to the research agenda related to local government, local administration and local power in Brazil, through the analysis of the literature about diffusion and dissemination of innovations and public policies and through the discussion about the factors that explain the dissemination of innovative policies, programs and practices.
