Abstract
Based on the data related to the economic vitality of Shanghai in 2019, an appropriate index system from the four aspects of economy, industry, innovation and social life was established. Then three experimental and mathematical statistics analysis methods: PCA, GC-TOPSIS and discrete coefficient method are used to evaluate the economic vitality of Shanghai, and the rank of each district was obtained by a simple ranking aggregation algorithm- Borda Count. After qualitative and quantitative analysis, the conclusions are as follows: First, the Pudong New Area and Minhang District rank at the forefront, mainly because of their superior geographical location and the support of government policies. Secondly, there are two indicators that can better explain Shanghai's economic vitality. They are the social retailgoods and the total export-import volume. According to the conclusions of the study, it is suggested that all regions of Shanghai should adhere to reform and opening up and advocate policy first. Then it emphasizes the opening and the progress of business.
