It seems clear that innovation is a key factor in increasing competitiveness of European enterprises in a global market with new players from developing countries. It also seems clear that innovation in organizations must necessarily be based on an open concept that allows them to take advantage of ideas, competences and external resources, hence the concept of Collaborative Networks. Among the different types of innovation that are likely to be addressed within the concept of collaboration it is worth emphasizing what is known as Business Model Innovation. This kind of innovation aims to analyze and assess the logic of the business and establish new requirements for improving it, or changing it. This paper, based on several empirical research studies developed by the authors, describes the role that Collaborative Networks can play in the Business Model Innovation process.
