Through a comparative study of collaboration forms within different spaces of creativity and innovation, this article proposes a grid of reading knowledge communities develops in connection with innovative spaces. Thus, three types of collaboration can be distinguished: collaboration focusing on an economic logic (cost reduction and the renewal of work logics), collaboration based on a utilitarian logic (sharing of resources and means of work) and collaboration centered on an altruistic logic (mutual help and gift economy).
