Elements Analysis on Affecting Savings Deposits of Urban and Rural Residents Based on Factor Analysis

摘要

An effective and simple parameter estimating method—Factor Analysis method, for savings deposits of urban and rural residents model is proposed in this paper. As is known to all of us, there are many factors influencing savings deposits. The essential purpose of factor analysis is to describe, if possible, the covariance relationships among many variables in terms of a few underlying, but unobservable, random quantities called factors. This essay uses the method receiving two unrelated common factors which contain the whole information of five original elements. Therefore, we get the principal component deposit model. Through test, the new model could be proved to be accurate. Moreover the principal component deposit model has fairly good analysis result. In the end, this new model is applied to Chinese resident deposit forecasting based on the statistic data. From the comparison between new forecasting data and the statistic data, basing on the principal component analysis, we could conclude that the principal component deposit model is a quite effective and simple method for forecasting Resident Deposit.
