摘要
论文首次利用改进的"节约指数"并结合图形数据,对中国各省区资源消耗现状进行定量分析。结果表明:中国资源节约指数空间差异明显,总体上东部比西部节约、中部过渡(除山西外);低于全国平均节约水平的省域约占2/3,其中大部分在西部地区;此外,经济发展水平越高的省域,资源环境绩效水平相对越好。研究结果揭示了中国不同省域建设节约型社会的节约水平和资源利用效率差异,同时也为促进区域协调发展以及经济社会的可持续发展提供依据。
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.
