“…On the one hand, several authors have attempted to introduce the relational component into the traditional theoretical basis of firms' strategic orientation. Based on the consideration that relational marketing implies that "the firm is proactively involved in the creation, development and maintenance of committed, interactive and beneficial exchanges with certain agents of interest" (Harker, 1999: 16), several researchers have used the "relational marketing orientation" concept to refer to firms adopting a strategic focal point which promotes such performance (Sin et al, 2002(Sin et al, , 2005Tse et al, 2004). On the other hand, some authors have incorporated the knowledge-based approach into this relational vision by attempting to apply market orientation concept used in the firm's domain in a network context (Elg, 2002(Elg, , 2003Evanschitzky, 2007;Helfert, Ritter and Walter, 2002;Langerak, 2001;Siguaw, Simpson and Baker, 1999).…”
