Application of principal component analysis in evaluation of epidemic situation policy implementation

Abstract

In order to study the impact of various policies issued by the government on epidemic prevention and control, we first considered them from three aspects: the degree of leniency of policies, the degree of stringency of policy implementation and the degree of self-consciousness of individuals, broken down into 10 indicators, designed a questionnaire to collect relevant data. Using Principal Component Analysis (PCA), 4 principal components were extracted from 10 indexes, and the scores and total scores of each principal component were obtained. Finally, the corresponding suggestions are given.
