摘　　要：针对我国药品流通业存在“多，散，小”、效率低、流通费用高的问题，当前的主流观点是提高行业集中度、退出国有股份等.本文首先通过Pastor筛选法筛选出投入变量，构建DEA模型。并计算样本企业的效率。再用Tobit模型分析影响DEA效率的因素。结果发现：（1）企业规模与综合效率、纯技术效率正相关，但与规模效率负相关，因此在提高行业集中度的同时应当注意规模效率的提高；（2）产商一体化的混业经营比专业化经营更有效率；（3）国有股份的存在有利于效率的提高，同时由于药品的特殊性，应适度保留国有股份。To solve problems in current China＇ s pharmaceutical distribution enterprises, the current mainstream view is to increase industry concentration and quit state - owned shares. This paper firstly screened input variables by Pastor screening model to build the DEA model to calculate the efficiency of sample enterprises, then used Tobit model to analyze the factors that affect the DEA efficiency. The results of the analysis showed： 1. Firm size and enterprise TE, PTE had positive correlation, but firm size and scale efficiency had negative correlation, so when we improve industry concentration, the scale efficiency should also be noted; 2. The the integration of producers and circulations enterprises can lead to more efficiency than specialization; 3. The ex- istence of state - owned shares can bring about more efficiency, especially due to the specialty of medicine, to moderately retain the stateowned shares is necessary.
