摘　　要：目的:通过对全国数百家医疗机构药品购销数据进行处理,统计抗感染类别的药品费用,分析抗感染类别药品的市场垄断程度,并对出现各种市场类型的可能原因进行阐述。方法:选取行业的绝对集中率(CRn指数)作为集中度指标反映抗生素药品市场的竞争或垄断程度。结果:2006-2011年抗感染类药品整体市场集中度较低,为竞争型市场。结论:抗感染类别药品市场集中度不高,抗菌药物次亚类市场中,则普遍表现为中等寡占及以上。氨基糖苷类抗菌药、氯霉素类抗菌药、四环素类抗菌药属于高集中寡占型,集中度较高;β-内酰胺类抗菌药、青霉素类等抗菌药属于中集中寡占型,集中度中等;其他β-内酰胺类抗菌药类市场属于竞争型,集中度较低而且仍然在下降。Objective： To calculate the expense of different kinds of anti-infective drugs,and analyze the market concentration ratio of anti-infective drugs in China. Methods： The purchase and sale data from database of center of China medicine institute were well collected and analyzed by statistical method. The indicator concentration ratio（ CRn index） was used to reflect the degree of monopoly and competition in the market,while n is usually equal to 4 or 8. According to the American economist Bain’s classification of markets,markets were divided into six types. Results： The eight-firm concentration ratio of all antibiotics between 2006 and 2011 was around 26%. The market of anti-infective medicine was low-concentration competitive. Conclusion： The concentration ratio of overall anti-infective drug market is not high. Among the subgroups of anti-infective drugs,the markets of chloramphenicol,aminoglycosides and tetracycline medicines are highly concentrated,the concentration ratios of markets of subgroups of anti-infective drugs generally increased between 2006 and 2011.
