Recently, "innovation" has become the core strategy of the enterprises; it also attracted attentions by researchers. In Management Science, The research of innovation is not only confined to technological innovations but also including organizational and managerial innovation. This thesis examines three types of innovations within a framework of a supply chain, which includes innovation project, the process of diffusion of innovation concerning the supply chain, and the ownership of the actors on the main elements in the process. The research objective of this thesis is to verify the steps of diffusion to an innovative project and analyze the absorbing level of the actors within an innovation project, with the actors including the top management level, the division level and operation level in a big industrial group. A conceptual model has been established on the basis of literature review on the theories of innovation, supply chain management and project management. Subsequently, an exploratory qualitative study is conducted in Schneider Electric. The data was collected through three approaches: individual interviews, field survey and internal documentations. Then, the quantitative content analysis including the coding technique is used to deal with the data obtained. The results provide that the supply chain management innovations is not only including organizational innovation and managerial innovation, but may also contribute to technological innovation. The diffusion of an innovative project involves five steps: i) Identification of problems, ii) Matching problems / innovative project, iii) Launching of the project, iv) Execution of the project, and v) Closing of the project. The analysis also shows different absorbing level from the actors on the mains elements of this process. In this thesis, the model of diffusion of innovation project has been validated; the contributions and perspectives have been thus proposed.
