Sustainability Assessment of Autonomous Regions in China Using GRA-SPA Method

Sustainability development is a core issue in autonomous regions’ construction and development. The paper evaluated the sustainability of five regions Western China from 2010 to 2019. In order further analyze sustainable level regions, it compared with three provinces largest GDP Central past years, similarly, Eastern China. A new weighting method was proposed by combining grey relational analysis (GRA) set pair (SPA) methods that not only correlation between indicators ideal points but also status trend. can ensure objectivity indicator weight. Firstly, reference point determined degree positive point. Secondly, constitute system, relation number used trend determine weight objectively. results showed progress increased slowly 2010–2019. For example, Ningxia Xinjiang saw slowest growth. prime reason economic has declined severely. Although Inner Mongolia presented highest increasing trends, growth rate value 0.75%. contrast, other negative Regarding dimensions, performance ideal, environmental most ideal. This conclusion implicates necessity urgency improving coordinated dimensions
