Study on the evaluation model of collaborative governance capacity of sustainable supply chain in water diversion projects

In order to objectively evaluate the operation effect of the Sustainable Supply Chain (SSC) collaborative governance of Water Diversion Projects (WDPs), this paper, from the perspectives of SSC and collaborative governance, and according to the existing modes of SSC collaborative governance of WDPs, constructs the collaborative management mechanism of related subjects of WDPs, and then constructs the evaluation model of the collaborative governance capacity of WDPs by using the DEMATEL (Decision-Making Trial and Evaluation Laboratory)-ANP (Analytic Network Process) method. Specifically, in this paper, the indexes at various levels are selected through literature mining and text analysis, and the mutual influence degrees among index are determined with the help of DEMATEL, so that the causality diagram can be drawn. On this basis, we obtain the global weight and the mixed weight of each index by using the ANP method and SD (Super Decisions) software, thus determining the relative importance of each index. The study finds that with regard to the SSC collaborative governance capability of WDPs, the highest requirement is made on Information Collaboration Capability (ICC) which also provides the foundational guarantee. The proportion carried by Subject Participation and Collaboration Capability (SPCC) is the lowest, however, its mixed weight is 1.9077, second only to ICC. Both Water Quantity Collaboration Capability (WQCC) and Water Quality Assurance Coordination Capacity (WQACC) account for a high percentage, which is consistent with the actual situation. The study provides a capability evaluation index system for the SSC collaborative governance of WDPs, enriches the theory of SSC collaborative governance of WDPs, and provides decision-making support for the operation and management of WDPs.
