Industrial chain toughness evaluation method and system based on multi-chain coupling

The invention discloses an industrial chain toughness evaluation method and system based on multi-chain coupling, and relates to the technical field of manufacturing industrial chain toughness evaluation.The method comprises the steps that firstly, a topological structure of a modern industrial chain needs to be determined through a complex network method, and characteristic indexes of a complex network are measured; secondly, key indexes beneficial for evaluating the toughness of the modern industrial chain are identified from four dimensions of a value chain, a technical chain, an innovation chain and a supply chain, and a modern industrial chain toughness evaluation index system under the perspective of multi-chain coupling collaboration is constructed; and finally, a multi-dimensional evaluation pyramid model is constructed and applied to comprehensively evaluate the toughness of the modernized industrial chain, the pyramid model can be used for evaluating the current situation of the toughness of the mod
