This paper deals with the influence of open innovation in cultural and creative industries. Creative industries can often be characterized as territorialized industries. Their territorial anchor constitutes a structural characteristic, with a strong influence on the innovation process, and on the conditions of valorization of cultural goods. So, the interpretation highlights the privileged role of shared and situated innovation: concerning the construction of a cooperative model, intellectual property protection, risk reduction, influence of public policies, and conditions for developing and capturing externalities. By contributing to the deployment of specialized assets in cultural and creative industries, open innovation reinforces the factors for a differentiation advantage. The pervasiveness of open innovation and the diffusion of spillovers among creative industries also rely on the economy of contribution, in the framework of the digital economy, local systems of innovation and the third sector. The economy of contribution results from the relations between contributors and from the spillover effects, in creative industries. Thus, open innovation and contribution are increasingly involved in “cognitive-cultural production systems”, based upon the growth and spillovers of creative industries. The differentiation advantage linked to industries and territories now depends on territorial design, combining the driving forces of open innovation, creative entrepreneurship, and the metropolitan cultural governance.JEL Codes: A13, D62, D63, L86, R12, Z11
