4. Discussion
The RBV recognizes that the strategic resources a firm controls are essential to superior performance (Barney, 1991). Such a perspective has provided a needed alternative to other views of strategy that emphasize external factors, such as industry structure (e.g., Schmalensee, 1985). As a result, theoretical attention of RBV research has mostly remained on internal resources, whether tangible, such as ownership of a gold mine, or more intangible, such as capabilities and core competencies (Day, 1994; Hunt & Morgan, 1995). The central insight of this article is that the firm's relationships with multiple stakeholders, including those that are external to the firm, constitute a resource. To the extent that these relationships are valuable, rare, inimitable, and organizationally embedded, they can lead firms to respond to those stakeholders. This ability, in turn, provides a differentiation and/or cost advantage, which ultimately enhances firm performance.
