Evaluate Information Coupling in Cluster Supply Chain

Information coupling is an important characteristic and affects the stability and reliability of Supply Chain System. In order to evaluate how well a firm is coupled with its supply chain, the paper which refers to reference the urbanization and ecological environment filed used the system coupling theory, builds coupling degree evaluation model to measure the degree of information coupling between a firm and the members of its supply chain structure from cluster supply chain (CSC) perspective. The coupling degree model (CDM) is a 2-tuple index which describes information availability and information intensity in both directions of the cluster supply chain. Result of the paper proves that information degree of coupling in cluster supply chain is higher than single supply chain by comparing data.
