Abstract

The change of private car ownership is a long-term nonlinear process with complicated influencing factors and nonlinear relationship also exists among them, which requires reasonable and accurate methods for analysis and prediction. In order to solve these problems, the traditional principal component analysis (PCA) method is improved in this study. Considering the integrity of the data, eight representative main factors influencing China’s private car ownership are chosen. Firstly, the improved PCA method is used for “nonlinear” process of dimension reduction. Then, the Logistic regression model is applied to describe the relationship between private car ownership and the extracted principal components. The improved PCA-Logistic regression model is proposed finally. Compared with the results of the traditional PCA-Logistic method, it can be found that the improved PCA-Logistic model can effectively eliminate the nonlinear relationship between the data and it can change the quadratic nonlinear principle component regression curve obtained by the traditional method into a linear curve, which is more in line with the principle of PCA. The obtained nonlinear Logistic regression curve is in better agreement with the actual data, indicating that this method can evaluate the private car ownership in China more accurately. Based the model, the private car ownership in China from 2020 to 2024 have been predicted and the results show that China’s private car ownership may exceed 300 million in 2020 and exceed 400 million in 2024.
