While the benefits of university-industry collaborations are documented in the literature, the means of achieving efficient collaborations for both scientists and industry are still a matter of debate. Such associations exist and have been documented at individual, project and institutional levels. It is envisaged that, in these relationships, each stakeholder - industrialist and scientist - manages to mobilize the partner's resources in the service of its own cause. Through 30 interviews with 11 joint laboratories, a partnership research tool that structures the relationship through a laboratory format, our study aims to identify these exchange mechanisms at the service of the renewal of scientific and industrial issues. We show how this laboratory format, piloted by a public research organization, is an interesting tool for accumulating resources that will multiply the impact of the partnership relationship, for both parties.
