Research on Mathematical Model of National Pharmaceutical Industry Evaluation Index System
Aiming at the problems of the drug market under the background of the national unified big market,according to the eight evaluation index system of the pharmaceutical industry,the specific relationship between the eight evaluation index system and the quality of economic operation was obtained through the Pearson correlation coefficient.Through the BP neural network prediction model,the degree of market unification was quantified,and the improvement space and key problems of the drug market in each province were obtained.Based on the relevant data from 2019 to 2023,the GM(1,1)grey prediction model is established to find the solution to the discrimination problem.
