Abstract：Objective:To explore the impact of medical security levels and capital market performance on the prices of commonly used retail drugs under the market-driven price comparison mechanism,and to provide empirical evidence and suggestions for improving the formation mechanism of retail drug prices and optimizing price regulation.Methods:The chained Fisher's index was calculated using the price data of commonly used retail drugs in the"Medical Insurance Price Pass"mini-program of Shenzhen from December 2023 to February 2025.The Lasso regression model was used to screen the variables of medical security levels and capital market performance,and the Ridge regression model was employed to study the correlation between the price index and each variable.Results:The number of participants in basic medical insurance,the total outpatient volume of public hospitals,and the trading volume of the CSI All Share Health Care Index were negatively correlated with the price index,while the number of participants in maternity medical insurance and the trading amount of the CSI All Share Health Care Index were positively correlated with the price index.Conclusion:Continuously deepen the three-dimensional coordination of"system-market-technology"to promote the transformation of drug price governance from passive response to active regulation.
