Abstract
With the arrival of the "14th Five-Year Plan", China's economy has ushered in new opportunities but it is facing great challenges at the same time. According to the short-term economic fluctuation theory, through the visual chart study of macroeconomic indicators, this paper analyzes the changing trends of consumption, investment, import and export, which are the "troika" driving the economy. Furthermore, combining the relevant macro data and theoretical model, the calibration of parameters and numerical simulation are carried out with Matlab software, and the model results support the following conclusions well that China's macroeconomics faces four problems: first, the slow recovery of consumer demand; second, the weak growth rate of the investment; third, the rising proportion of structural unemployment; fourth, the unstable situation of international trade. In the end, this paper explores the causes of these four problems and gives a series of policy recommendations.
