Outsourcing allows companies to entrust to an external actor the management of part of their activities, particularly for peripheral processes to improve its performance. Outsourcing, in its strategic and global perception, can also be a support lever of activities related primary processes in a framework of partnership, facilitated by a process of innovation and promoting sustainable development especially in the area public. This is what this thesis seeks to demonstrate using a qualitative assessment of the main organizations responsible for the management of transport infrastructure in Morocco (Morocco's National Society of highways, roads department, National Agency of ports, National office of Airports and National Office of railway). This research adopted a recursive, abductive and inductive approach to first validate the theoretical corpus mobilized, and then design the analysis model of the empirical field and finally build the modeling of the proposed outsourcing oriented strategic partnership, innovation and sustainable development. The main components of this model are PARI model which considers the choice of partner the key to innovation, the structural model which distinguishes four levels (Corporate, Strategic business unit, Strategic Outsourcing, Sales Force) and management style model for every organizational level which is based on leadership, innovation and sustainable development. The appropriation of this modeling by public organizations will allow them the animation of the proposed economic model to make it an engine of entrepreneurship and unemployment resorption.
