Abstract In this paper, according to the meaning of urbanization, 13 indexes in 1995, 2000 and 2005 which have close relationship with urbanization for 31 province-level regions(Taiwan, Hongkong and Macao are not included) were chosen to compose the data sheet. Then the generalized component analysis was used to evaluate the comprehensive urbanization level in different regions. According to the analysis in factor process in SPSS software, three principal components can be extracted which reflect three main aspects of the urbanization:(1) Population structure and urban landscape; (2) Income and consumption level of urban residents; (3) Urban infrastructure construction. Then the three principle components were combined into one comprehensive index to reflect the whole urbanization level. The result shows:(1) Both the urbanization level in 3 years and its increase in eastern region are much higher than that in central and western regions. The gap of development quality and speed among regions are outstanding; (2) The overall quality of urbanization has a big improvement during the analyzing period. To some provinces, especially those in eastern regions, the improvement of living conditions and income has become the main aspects of urbanization. But in central and western regions, migration from rural area to urban places is still the main form of urbanization; (3) The harmony between different indexes is good. The main social and economic index is consistent with the urbanization level. In conclusion, the future policy should focus on the balanced development among different regions. To the central and western regions, it is necessary to improve the quality of urbanization. To the eastern region, industrial updating, efficient resources utilization and improvement of environment quality should be paid more attention to.
