We will improve the level ofa local people's life, to somewhere better and faster development, we must fully understand the current situation of economic development. Therefore, the existing research on the development of future economic development has a very important guiding significance. ponent analysis (also called ponent analysis, is to try the original bined into a new set of prehensive index instead of the original index has nothing todo with each other, at the same time, according to the actual need to mend a few prehensive response as much as possible the original information of indicators. Isa generalization of the ponent analysis and factor analysis, it is also will have the intricate relationship between prehensive toa small number of several factors, and to recreate the relationship of the original variables and factor, at the same time according to different factors can also categorize variables,. ponent analysis and factor analysis isa multivariate analysis ofa statistical method of dealing with the dimension reduction. In this article, through learning and access to relevant data found nine representative indexes of12 cities in heilongjiang province, using the SPSS statistical analysis software to the indicators of ponent analysis and factor analysis of the characteristic value
