Abstract: By adopting the main theoretic points of RBV and combining with the characteristics of shared resources, which lie on the level of industrial clusters and are used by the firms in cluster exclusively, based on shared resources, a concept model of competitive advantage for the firms in cluster is built. Then, by using the method of Structural Equation Modeling(SEM), the concept model is validated and modified statistically. Through understanding the paths that the shared resources act on the competitive advantage of firms in cluster via strategic resources, the mechanism of shared resources acting on competitive advantage of firms in cluster is elucidated.

Key words: shared resource, firm in cluster, competitive advantage, path
