药品集中招标采购政策的实施效果——基于中标企业数量与中标价格的实证分析

The impacts of medicine centralized bidding and purchasing policy: An empirical study on the relationship between the bid winners and the bidden prices

目的:从中标企业数量与中标价格的关系角度分析药品集中招标采购政策的实施效果。方法:检索31个省市自治区药品集中招标采购中标结果,采用最小二乘回归方法定量分析药品中标企业数量对中标价格的影响。结果:与直觉相反,中标企业数量与药品中标价格呈现出正向关系;相对于基本药物组,非基本药物组中药品中标企业数量对中标价格的影响更大。结论:现行的药品集中招标采购政策仍需进一步完善。

Objective： This paper aims to analyze the impacts of medicine centralized bidding and purchasing policy based on the relationship between the bid winners and the bidden prices. Methods： A data collection method was used to collect data from medicine centralized bidding and purchasing policy in 31 provinces and OLS method has been employed to analyze impacts of the number of bid winners on the medicine prices. Results： The results showed a positive correlation between the number of bid winners and the bidden prices,which was a counter-intuitive appeal.In the group of non-essential medicines,the number of bid winners had a stronger impact on the bidden prices than in the group of essential medicines. Conclusions： The current medicine centralized bidding and purchasing policy does not achieve the expected objective and needs to be further improved.
