The link between education investments and the workforce in China will be investigated under the current population fluctuation. It is widely agreed that education investments prompt employment. However, it remains ambiguous as to how the two variables correlate in Chinese society. This study aims to answer the question. The study first investigates the current social milieu and employment trends in China, then focuses on population change, the labor market, workforce shift, and the aging problem. The first is to find data on employment trends in the three sectors and education investment from two chosen periods. The research also further analyzes the correlation between the selected data. The model is the Autoregressive Composite Moving Average (ARIMA) model to examine the relationship between education investment and employment figures. This model helps build a new perspective on the complex relationship between education trends, population, labor, and work. Furthermore, the methodology of this study also provides a framework for subsequent research that can delve into the dynamics in different markets or economies.
