The appraisal indicators system is set up and the mechanisms and paths of economic operation in the central region of China during 2001-2005 are analyzed by means of generalized principal component analysis(GPCA).

Through processing the data in 1990s with generalized principal component analysis(GPCA), this paper describes the dynamic development paths of the cities in mining area.

In this paper,an evaluation index system for rural residents living level is established,and generalized principal component analysis(GPCA) method is applied to depict the temporal changes of rural residents living-level of mid-china provinces,timed from 2001 to 2006.

This paper intends to give the methods of principal components analysis for the instant planar data and global principal components analysis for the multidimensional dynamic data system in the environmental evaluation,especially focuses on the synthesis and simplification of the sequential solid datasheet,then gets the satisfied result in the examination.

Based on designing evaluation index system,this paper puts global principal components analysis to the related evaluation data of six provinces in central China area from 1997 to 2006,uses of cluster analysis to classify,and contrastively analyzes mutative law on land intensive utilization in central China area.

Be living in the data tables indexed by time of the community economy data in 2003,2005,2007 what constitutes the economy sequence base of one-hour economy circle of Chongqing,we use the all-around principle component analysis means and the radar chart analysis means to figure the economy divergence changing.

According to 13 main cities datum,Jiangsu,from 2000 to 2003,the article evaluates the factors of 13 main cities economic development situation and effective factors in Jiangsu,by building principal component analysis of overall model.

The all-around principle component analysis method based on the data table indexed by time can provide a efficient scientific quantitative method for dynamic evaluation of regional economic development level,is a multi-index comprehensive appraisal method.

Based on a systematic description and theoretic analysis on the reform design project,combined with the practice of the reform of he rural credit cooperatives in some district in the West Regions,and applying the time series GPCA method,a positivist analysis on the reform of the rural credit cooperatives has been made in.
