基于数据包络分析的我国医药制造业相对效率分析

Analysis of relative efficiency in Chinese pharmaceutical industry based on data envelopment analysis

运用数据包络分析(DEA),对十一五期间医药制造业中的各省份化学原料药、化学制剂、生物制剂、中成药和中药饮片子产业的技术效率均值、规模效率均值和综合效率均值的变动进行分析。整体上,规模效率的差异小于技术效率的差异,一些省份的效率与前沿面省份的差距较大。中成药和中药饮片的效率差距最小;化学原料药的规模效率和化学制剂的技术效率波动较大,但差距有减小的趋势;生物制剂的效率有降低的趋势,且各省份的效率排名不稳定,差距有增大的趋势。

We analyzed the efficiency fluctuation of chemical raw medicines, chemical agents, biological agents, Chinese patent medicines and decoction pieces during the Eleventh Fiveyears Plan with the help of data envelopment analysis. The average efficiency values contain technical efficiency value, scale efficiency value and the scale and technical efficiency value. Generally, the scale efficiency difference is less than the difference in technical efficiency, and the gap between some provinces and frontier provinces is larger. The gap between Chinese patent medicine efficiency and decoction pieces efficiency is the smallest. The fluctuations are large in scale effi ciency of chemical raw medicines and technical efficiency of chemical agents, but the trend turns small. The effi ciency of the biological agents has a decreasing trend, and the efficiency of the provinces ranked unstable so the gap may increase.
