The urban environment is a supporting systemto the sustainable development of city. Taking the urban area of Chongqing as an example, this paper establishes theindicator system for assessment of the coordination between urban environment and economy according to the resultfrom principal component analyses by software SPSS11.0. Meanwhile, the weight was assigned for each indicator basedon the load of the first proper principal components. Through computation of the coordinated development model set upaccording to the knowledge of statistics, the paper draws the conclusion that the situation of the coordination betweenenvironment and economy in Chongqing developed well from 1996 to 2004. Finally, countermeasures for the coordina-tion in the coming years are proposed.展开更多
