In 2022, the outbreak of the Russia-Ukraine war, the disruption of the global supply chain, and many other factors have had a huge impact on the global economy. To control the high inflation rate and curb economic overheating, on March 16, the Fed raised interest rates for the first time since 2018 to curb inflation and stabilize prices. The Fed’s interest rate hikes have a significant impact in many areas, including the stock market. To find the relationship between them, the paper uses computer simulation modeling. This paper first introduces the impact caused by the Fed’s interest rate hikes on different markets and analyzes the spillover effect. Then this paper selects data from the USD exchange rate and Apple stock price before and after the Fed’s interest rate hikes and uses the ARMA-GARCH model to model and analyses the data to study how the Apple company has been affected by the Fed’s interest rate hikes and predict the future development of the Apple stock price. Finally, this paper analyzes the factors that will affect the stock market. The analyzing process is mainly based on the Stata application.

In recent years, the technology export control policy with the Entity List as the core tool has become an important tool for the U.S. to exert maximum pressure on China, while the high-tech industry represented by the ICT industry has become an important front for the U.S. to implement strategic containment against China. This paper innovatively measures “export control intensity” by combing the updated history of the Entity List of the United States, and establishes panel data based on the monthly trade data of representative goods in the ICT industry of China and the United States from 2017 to 2021. A multiple linear regression model for the empirical analysis is established with the help of the Stata16.0 software tool to explore the influence of the import and export trade of high-tech industries between China and the United States under the background of the implementation of technology export control against China. The results show that the intensity of the U.S. high-tech export control to China has been increasing continuously in recent years, which not only affects the import and export trade of China’s high-tech industry to a certain extent, but also has a negative impact on the import and export trade of the U.S. high-tech industry.
