Establishment and empirical study of drug price index based on Hedonic model
-
摘要: 目的 基于Hedonic模型编制药品价格指数,进行实证分析。 方法 从全军抗菌药物临床应用监测数据管理中心、中国药品监督管理局(CFDA)官网、药智网收集了2014年10月至2017年6月抗菌药品消耗相关数据,采用Hedonic价格指数进行实证分析。 结果 基于Hedonic模型建立的价格指数呈下降趋势;其中有效成分含量、药品日剂量数(DDDs)、药品日均费用(DDDc)、药品最高价格、药品最低价格等与价格指数呈正相关,而是否口服药品、同品种厂家数量、是否医保药品、是否国产药品、药品使用人数等与价格指数呈负相关。 结论 基于Hedonic模型建立起来的药品价格指数涵盖了10个特征属性,可有效反映供求变化对药品价格的影响。

Abstract: Objective To establish the drug price index based on Hedonic model and conduct empirical analysis. Methods From the monitoring data management center for clinical application of antimicrobial agents of CPLA, the official website of the former China drug administration (CFDA) and the website of pharmaceutical intelligence, data related to antimicrobial drug consumption from October 2014 to June 2017 were collected and the empirical analysis was conducted by the Hedonic price index. Results The price index based on Hedonic model showed a downward trend. The effective component content, daily dose number (DDDs), average daily cost of drugs (DDDc), maximum price of drugs and minimum price of drugs were positively correlated with the price index, while the price index was negatively correlated with oral drugs, number of manufacturers of the same variety, medical insurance drugs, number of domestic drugs and number of drug users. Conclusion The drug price index established based on Hedonic model covers 10 characteristic attributes, which could effectively reflect the impact of supply and demand changes on drug prices.-
