With the emergence of the NGOs in our globalized economies, large companies developdiverse types of corporate-NGO partnerships (CNPs). Some researchers raised interrogations on their strategic issues. In our thesis, we study the CNPs specific contribution to the evolution of large companies’ business model (BM).Drawing on a longitudinal processual case study at Suez-Environnement, we highlight three main contributions of CNPs: first, some types of CNPs influence company’s strategy by taking part in the activities’ segmentation; second, they contribute to design and to implement the BMs resulting from the new segmentation; third, they play a driving role in the company’s BMs portfolio evolution.From these results, we suggest: an extended approach of BM’s purpose including societalperformance; an enhanced representation of the BM concept, called RCOV-PsE model,structuring four interacting components; and the meta business-model concept that we define as: a socio-economic value creation logic appearing from inter-BM relations.
