Determinant factors of participation in the co-production of ideas to solve public problems

What are the determinant factors of citizens' participation in the collective production of ideas to solve public problems? In order to answer this question, 510 citizens, enrolled in Prmio Ideia, a platform of collective production of ideas, responded to a questionnaire pointing out determinant factors identified in literature about participation in online platforms that are decisive for their own interest in participating. The structural equation analysis highlights that the feedback given by a public institution to citizens and convenience are determinant factors for participation. This interest in participation, however, does not necessarily imply effective participation. It is concluded that the application of the ideas created through the platform and the feedback to the participants are determinants for social participation and the study suggests further research approaching the motivation of companies that propose such initiatives.
