Abstract: Abstract： The studies of the definition of resources all focus on the function of resources wherever they coming from a macro perspective or a micro perspective. Here, resources are defined as any things, tangible or intangible, that provide advantages or disadvantages for a specific main body. On the classification of resources, scholars at home and abroad put forward the two important criteria based on resource-based view. The first one involves the dimensions, such as ownership, heterogeneity, and incomplete mobility of resources. The second one is only concerned two dimensions, namely, resource itself and the relation between resources and competitive advantages. However, the limitation of the those two criteria concentrates on the impact of internal resources of firms on competitive advantages. A “3-3” model is proposed, which emphasizes on the interactive role of three major criteria, namely the visibilities, functions, and condition constraints of resources.
