Knowledge management practices are used in collaborative networks promoting innovation in order to share critical knowledge among network members towards improving organizational results. This paper proposes to explore the channels and practices for knowledge sharing in collaborative networks, by means of an exploratory multiple case study carried out in two types of collaborative networks: (i) industrial associations; and (ii) science and technology parks. Empirical evidence has been collected from interviews with managers of the collaborative networks and of organizations participating in the collaborative networks. The contribution of this paper to the knowledge management literature is twofold: (i) it provides a characterization of the channels and technology used for knowledge sharing in collaborative networks based on empirical evidence and (ii) it describes knowledge sharing practices used among organizations to foster new forms of connectivity between groups and individuals. Keywords: knowledge sharing, collaborative networks, industrial associations, science and technology parks. 1 Introduction Science and Technology Parks (STPs) have an impact in the economic growth and regional development [1, 2]. Companies in environments of STPs can benefit from the knowledge spillovers resulting from the research, ideas and experiences from both universities and research centers [3] or by the contact with other companies located in the park [4]. Industrial associations (IAs) also act as facilitators to provide critical knowledge for their associated companies, which can result in innovation and competitive advantages [5]. The discipline of Knowledge Management (KM) is concerned with the organizational knowledge as a process coming from individuals in a collectivity, providing benefits to individuals, employers, communities of practice and organizations [6]. The challenge of this paper is to identify practices for knowledge sharing in networked innovation environments, such as STPs and IAs, contexts that to
