The results show that the comprehensive development degree (CDD) of the tourism-air environment system mainly maintains stable with fluctuation and the gap among different reaches in the Zone is declining; the coupling coordination degree’s (CCD) tendency in most regions remains similar as in the previous decade. The results illustrate that the method combing information entropy weight and the technique for order preference by similarity to an ideal solution (IEW-TOPSIS), coupling coordination degree model (CCDM), and gray GM (1, 1) prediction model is effective in evaluating the coupling coordination relationship between the subsystems of tourism and air environment and in proposing specific countermeasures for tourism development and air environment governance.
The interaction between water governance and tourism is complicated and significant so that the study of the coupling coordination between these two subsystems is important. This study analyzes the correlation mechanism of the water governance-tourism system, constructs the composite and aggregated evaluation system which consists of 5 dimensions and 15 indicators, uses information entropy weight technique for order preference by similarity to an ideal solution method to evaluate the development degrees of both water governance and tourism growth of the 11 regions in the Yangtze River Economic Zone, analyzes the two subsystems’ relation of coupling coordination temporally and spatially with the coupling coordination degree model, predicts degrees of coupling coordination of the regions for the next 4 years with gray system prediction model, and proposes specific and generalizable countermeasures. The results show that these methods can provide an effective reference to evaluate the coupling coordination development of water governance and tourism and to provide scientific and generalizable countermeasures for enhancement.
Within the sustainable urbanization framework, two dimensions, namely, social urbanization and environmental urbanization, have complex coordinated interactions. To better understand the coordinated interaction status between the two dimensions of sustainable urbanization, an empirical study was carried out in the 14 cities of Hunan Province, China, from 2011 to 2019. This study establishes an integrated measurement framework, uses the coupling coordination degree model, information entropy weight analysis approach, and the Technique for Order Preference by Similarity to an Ideal Solution method to analyze the development degrees and coordinated interaction degrees of the two dimensions. The results show that the quality and efficiency of leisure facilities and water use have the greatest impacts on the coordinated interactions between the two dimensions. Besides, the development degrees of social urbanization and environmental urbanization are not consistent. What is more, the spatial noncorrelation of the coordinated interaction status demonstrates that the “high-quality development” tactics aiming to promote balanced development of dimensions among cities in China is feasible. Furthermore, corresponding suggestions are proposed, providing references for governments’ planning and decision-making processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
