Coupling Degree between Industrial Clusters and Supply Chains based on the Gray Correlation Model

Abstract

Competition among enterprises becomes increasingly intense with the development of economic globalization and traditional industrial clusters and supply chains cannot meet changing market demands. In the study, coupling elements and contents between industrial clusters and supply chains are illustrated, and then a coupling degree model and an index system are discussed in detail. Finally, the coupling degree between industrial clusters and supply chains in Changsha-Zhuzhou-Xiangtan region is measured by using the gray correlation model.
