Then, 800 health care index and seven determinants are?chosen for empirical research. This article collects corresponding raw data through?the official website and Wind. By R, important factors are processed, and principal?component analysis is used to obtain their relationships, analyze the influence degree?individually, and form new components. After that, use new components to construct?a model to understand the impact of different factors on the pharmaceutical industry.?After in-depth analysis, the contents are summarized, and limitations are written.
