When drawing together the three different theoretical views} the arguments for and against ching them to the research of SRM, it can be said that all these views are applicable, pointing to the different focus areas of SRM research, Applying TCE underlies the aspects of efficiency and cost focus. Especially, it defines the boundaries of a firm. RBV refers to the firm’s internal value creation through its resources and capabilities of a firm. Value can be created from supplier relationship management through learning mechanisms, routines and experience. RDP applies the aspects of external and internal social relations, power distribution and the level of dependency on external counterparts. It aims at the optimization of the continuity of the business and the autonomy of a firm. As a summary, it can be said that these theories support the purpose of supplier management (diffusion of supplier information between business units, minimization of transaction costs, value creation through internal capabilities and resources, and reducing the risks of supply dependence and availability). Table 2 is a summary of the different theoretical views and elements applicable to the research of SRM.
