A Comparative Analysis of Wages Level of Private Enterprises in 30 Provincial Administrative Regions in China Based on Principal Component Analysis

Through the analysis of 19 statistical indicators of wages level in different industries in 30 provincial administrative regions, the principal component analysis method is used to compare and analyze the wage levels of private enterprises in different provincial administrative regions in China. A region with a score greater than 0 indicates that private enterprises have a better wage level, and a comprehensive score of less than 0 indicates that private enterprises have poorer wage development. Among them, Beijing’s private enterprises have the highest overall wage rate, which is much higher than other provincial administrative regions. The study also found that there is a certain degree of similarity between the level of wages of private enterprises in various regions and their level of economic development.
