Regional water resources coordination (RWRC) plays a prominent role in long-term sustainability. In order to achieve harmonious utilization of regional water resources, it is suggested that local governments should focus on balancing three goals - security, equity, and efficiency, resulting in both ecological and socio-economic benefits in a region. Therefore, this paper aims to develop a comprehensive evaluation methodology for assessing the degree of RWRC. First, a security-equity-efficiency (SEE) evaluation indicator system is established. A novel multi-criteria decision-making (MCDM) approach that integrates decision-making trial and evaluation laboratory (DEMATEL) method and VlseKriterijumska Optimizacija I Kompromisno Resenje (in Serbian, known as VIKOR) method considering two different hesitant fuzzy linguistic term sets (HFLTSs) is then proposed. With this approach, a final ranking is obtained for six alternatives for the RWRC of the relevant regions (i.e., Shandong Province, Henan Province, Hebei Province, Anhui Province, Tian City, Jiangsu Province) in North China Plain, and the six relevant regions receive coordination performance ranking of II, III, V, I, VI, IV. Moreover, comparison analysis and sensitivity analysis are conducted to verify the effectiveness and reliability of the proposed method and dig deep into the RWRC conditions in the studied regions. Finally, some managerial suggestions are provided for strengthening the coordination levels in these regions. • A SEE indicator system is established for RWRC evaluation. • A hybrid MCDM method integrating different HFLTSs is proposed. • A maximum consensus and minimum hesitant degree model of HFLTSs is constructed. • Interval HFLTSs are introduced into DEMATEL method for indicators' weights. • A case study is presented to verify the effectiveness of the evaluation method.
