药品费用的影响因素分析——基于省级数据的实证研究

Analysis of Factors Affecting Drug Expenditure: an Empirical Study Based on the Provincial Data

通过2000-2011年的省级面板数据,研究人均GDP、老龄化、医疗保险、教育水平、新药的引入、价格规制等因素对药品费用的影响。结果显示:人均GDP、老龄化、医疗保险对药品费用的上升有促进作用,对人均住院药品费用的影响要大于对人均门诊药品费用的影响;教育水平与药品费用的关系不明确;新药的引入会提升人均药品费用;药品价格规制对降低人均药品费用的作用很小。因此,单纯对药品价格的抑制未必能达到控制药品费用的目的,应采取合理的措施,挤出或控制药品费用增长的不合理部分。

By the provincial panel data from 2000 to 2011, this paper studies the effects of Per capita GDP, aging, medical insurance, education level, the introduction of new drugs, price regulation and other factors on drug expenditure, finds that per capita GDP, aging, medical insurance can promote the rise of drug expenditure, the effect on per capita hospitalization drug expenditure is greater than the effect on per capita outpatient drug expenditure, the relationship between education level and drug expenditure is not clear, the introduction of new drugs can rise per capita drug expenditure, and the drug price regulation has little effect on the reduction of the per capita drug expenditure. It is concluded that the inhibition of drug prices may not be able to achieve the purpose of controlling drug expenditure, the correct approach is to take reasonable measures to squeeze or control the unreasonable part of the increase in the expenditure of drugs.
