The South-to-North Water Diversion project, as one of China's strategic projects, plays an important role in China's development. It's been 68 years since the project was conceived, in 2014, the central route project began to supply water. Users along the route are both beneficiaries and project influencers. Their behavior characteristics in the project operation, have become a topic worthy of study. In this paper, based on questionnaire conducted among government departments, enterprises and residents and stakeholder theory, under the theory model of Sustainable Supply Chain (SSC), around the Triple Bottom Line(TBL) including society, economy and environment, the ecological compensation, sewage treatment and reservoir operation management in Xichuan county were investigated and studied. A total of 289 answers were recovered. Through the survey, it is found that: Stakeholders include 15 township governments in Xichuan County, water conservancy project supporting facilities construction companies, ecological industry companies, water supply companies and other enterprises, as well as agricultural growers, rural farmers and non-agricultural residents in Xichuan County. Government stakeholders pursue the development of the overall operation of the project, while enterprises and residents pursue the development of individual economy. Finally, this paper lists the relevant indexes, which provides conditions for behavior evolution analysis and sustainable research of the project.

Measuring the collaboration of the sustainable supply chain of water diversion projects is of great significance to the sustainable operation of the project. To achieve this, it needs to develop a scientific and reasonable collaboration measurement method. Given the economic, environmental and social benefits of water diversion projects, and based on the theory of the sustainable supply chain, an order parameter index system for collaboration measurement was constructed in this study. The Dematel and Analytic Network Process methods were used to compute the local and global weights of each order parameter. A total of 161 valid questionnaires were collected from residents along the South-to-North Water Diversion Project Middle Route to measure its collaboration from 2018 to 2020. Results showed that the orderliness of the four flow subsystems of the South-to-North Water Diversion Project Middle Route increases year by year. Compared with the other three flow subsystems, the knowledge flow subsystem has a lower level of orderliness, suggesting that communication and exchanges among people along the route should be strengthened. Such findings can help identify the weak link in the collaborative management of the sustainable supply chain of water diversion projects and improve it in a targeted manner.

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.

We examine the information sharing behavior of stakeholders in the sustainable supply chain of water transfer projects in the context of "Migrating to Cloud, Using Digital Tools and Enabling Intelligence". We explored the evolution of the information sharing behavior of supply chain stakeholders using the China South-North Water Transfer Project as an example, and conducted simulations using MATLAB software to verify the optimal path of the supply chain. The results show that the information sharing behavior of stakeholders in the sustainable supply chain of water transfer projects is influenced by the water consumption of each municipality, the payment strategy of the South-North Water Transfer Project Fund and the cost of updating big data technology. Whether to obtain downstream demand information from the cloud. The upstream and downstream water supply companies should integrate the use of big data and real-time cloud-based intelligent services to make themselves and their partners more profitable in both directions, and to promote the overall coordinated development of a sustainable supply chain for water transfer projects.
