运用DEA方法对比研究创业板和中小板公司的效率问题. 为了削弱创业板和中小板这一环境因素对效率值的干扰,采用了三阶段DEA方法将收盘价、涨跌幅及成交量作为环境变量,同时以医药制造业公司为例验证了3个环境变量对公司效率的显著影响. 结果表明,环境因素对公司效率有显著影响. 其中,涨跌幅和收盘价对公司效率有消极影响,而成交量对公司效率的影响有双向作用,其对总资产和资产负债率有积极影响,对员工人数和主营业务成本有消极影响.

We studied the efficiency of corporations in GEM and SME board with DEA model contrastively. In order to weaken the effects of environmental factors which represent GEM and SME to efficiency ,this paper uses the three-stage DEA,and brings about the closing price,limit up and down,volume as environmental variables. It also evaluates the efficiency of a pharmaceutical manufacturing industry which is an example and proves the obvious effects of three environmental variables to efficiency. The results demonstrate that the efficiency is affected by environmental variables clearly. Closing price and limit up and down have negative influence on efficiency of corporations. But the volume have bidirectional influence on efficiency of corporations. It have positive influence on total assets and asset-liability ratio,and it have negative influence on the number of employees and main business cost.
