Abstract: This paper,using the improved"economic index" for the first time,chooses seven assessment indicators for generally characterizing the economic level of a thrifty society.It then defines the indicators weight by principal component analysis,calculates and analyses in an ordering way the economic indexes of the 31 provinces,autonomous regions and municipalities of China in 2005. Finally,by means of Arcview 3.3 software two diagrams are made:one is space distribution of the resources economic indexes of China,and the other shows the relationship between economic indexes and per-capita GDP in the provinces and autonomous regions of China.The results show that space difference of China’s resources economic indexes is significant,as a whole,the eastern part is more economical than the western,and the central is transitional except for Shanxi Province;and about two-thirds of the provinces’s economic level is lower than the nation’s average,mostly in the western part;besides,the higher the economic development level in a province,the better the performance of its resources and environment.The studies reveal that there are different economic levels of constructing a thrifty society and different resources use efficiencies in different provinces and autonomous regions of China.At the same time,it also can provide a basis for promoting balanced development among different regions and the socioeconomic sustainable development.
