Inter industry linkage combines with inter agency relation to form a network, which is called industrial cluster. Industrial cluster is an important field for studying regional growth, competitiveness, and innovation diffusion. Studying the linkage structure of elements constituting the industrial cluster is of great significance. However, there are few research achievements in this field, especially the quantitative ones. Based on industrial network theory, from the perspective of product linkage, this paper describes the industrial cluster as a network among sectors, and proposes a special structure of industrial cluster, that is, the core structure of industrial cluster, then puts forward a quantitative index system of core structure of industrial cluster, including the aggregation coefficient, radiation factor and centrality coefficient etc. The practical calculation example shows that the index system can describe the characteristics of industrial cluster in different regions, reflect the differences in competitiveness among regions and is an effective method for interpreting competitiveness using industrial cluster core structure.
