“…Existing studies on the evaluation of 3E systems mainly focused on the measurement of coordination level. The evaluation methods adopted in these studies mainly include analytic hierarchy process (AHP) (Veisi, Liaghati, & Alipour, 2016), principal component analysis (Mook & Overdevest, 2018), entropy weight method (Toumi, Le Gallo, & Ben Rejeb, 2017), data envelopment analysis (DEA) (Cucchiella, D'Adamo, Gastaldi, & Miliacca, 2018), fuzzy comprehensive evaluation method (Guo, Qu, Wu, & Gui, 2018), system dynamics (Xing, Xue, & Hu, 2019), etc. For example, Xing et al (2019) employed system dynamics to develop a dynamic model of the environment–resource–economic system, and used the urban data of Wuhan, China to establish a coupling coordination model.…”
