Analysis of the U.S. economy using mathematical modeling

Abstract

In recent years, China's economy and society have witnessed a considerable degree of growth and development. The industrial structure has been constantly adjusted, regional economic coordination has been continuously enhanced, and the overall economic quality has also been greatly improved. 2020 is the year of the U.S. election, and the attention of each U.S. election is undoubtedly worldwide. The world is watching to see which candidate is elected President of the United States. Because different candidates have different ideas about American policies. As the only superpower in the world, the various actions of the US will have a great or small impact on the world economy. What policies will different us candidates adopt and what impacts will they have on the US economy, finance or other fields, we need to analyze them according to the data. We quantified the relevant data of the US economy by means of quantitative methods such as statistical accumulation, statistical calculation, percentage quantification and fractional quantification. For the data such as GDP, total fiscal expenditure, public construction expenditure, medical insurance, etc., we directly made statistics, and then quantified them by summative calculation and other methods. This paper establishes a model of factors affecting economic vitality, makes use of fuzzy comprehensive evaluation, and finally analyzes the quantitative results, showing that the election of different candidates as US President stimulates the US economy. Through the analysis of the relevant economic data of the United States in the four years before and after 2016, we assessed the impact of the economic policy changes of different candidates on the economic vitality of the United States. By comparing and analyzing the relevant economic data of China in the first four years of 2016 and the last four years of 2016, after index processing, MATLAB is used to draw a comparison, and regression analysis model data is combined to compare the influence of different candidates' election in the US on China's economic politics. We will combine the data models of question 1 and question 2, and make Suggestions on China's economic countermeasures and policies in relevant fields by using models and qualitative assessment based on the relevant data of different candidates. To solve this problem, we will combine the results and influences of the models established in the first two questions, how to increase economic competitiveness and maintain sustainable development of economic vitality. Analyze the impact of these results on various aspects of China's development and make recommendations.
