Empirical Research of Sustainable Development of Chongqing City Based on Times Series Analysis & PCA

Based on the connotation of "sustainable development",we constructed,in this study,the sustainable development index system of Chongqing city,and studied quantitatively the sustainable development state of Chongqing city from the year of 1997-2004 by means of times series analysis PCA.The results showed that the comprehensive score of sustainable development of Chongqing city increased gradually from-1.49 in 1997 to 1.04 in 2003 and decreased to 1.00 in 2004;the coordination of economic sustainable development from1997 to 1999 did not change very much and was at a relatively low level,but it improved steadily from 2000 to 2003 and decreased thereafter;the relationship between the comprehensive score and partial scores could be described using the linear equation F=0.572F1+0.455F2+0.343F3;greatest attention in decision-making should be attached to the economic benefits of development,concurrently to the social equity problem in the development process.And we should strive to realize the efficient use of resources and ecological environmental protection so as to improve the coordination of sustainable development.
