Referring to the relevant literature, this paper firstly selects six major policies reflecting the effect of the presidential candidates' policies, and determines the quantifiable indicators of these six policies.  Using the total GDP of China at that time which represents the China's economy to establish multiple linear regression model, and obtain the indicators with strong correlation with China's economy. Finally, using the AHP, the effective indicators are assigned corresponding weights to score the impact of different policies of the Biden administration and the Trump administration on China's economy. The results show that according to the results of multiple linear regression, the Biden administration's tax policy has a significant impact on China's economy, and the tax amount is positively correlated with China's economy. The Trump administration's epidemic policy, infrastructure policy and trade policy towards China have a significant impact on China's economy. In addition, the cumulative death toll of the epidemic and the investment in infrastructure have a positive correlation with China's economy, and a negative correlation with China's total trade. According to the results of AHP, the policies of the Biden administration have a more positive impact on China's economy than those of the Trump administration.
