Since their creation, poles of competitiveness are becoming increasingly important in speeches and research literature. They have emerged as a relevant field of study and even a daily echo in business or the general press which report about changes in management practice within these clusters. Currently this structure, which is relatively nascent, focuses on the identification and dissemination of best practices among its actors. The aim of this paper is to outline a theoretical model of integration of inter- actors within the clusters. So, in order to develop this model, we explored a wide array of literature dealing with trust, clusters, and inter-organization relations. Finally, some issues related to the empirical examination of building trust are discussed. The contribution of this paper lies primarily in its study of the concept of trust in a multilateral context.
