【摘要】 对随机前沿面模型构造过程中存在负的和低效的产出数据进行处理和选择,对于建立随机前沿面模型有着重要意义。采用数据包络分析进行数据过滤,在过滤数据基础上建立随机前沿面模型,实证结果表明,该模型不但能够保证决策单元效率评价值与数据包络效率评价值次序大体一致,而且还给出了具体的前沿生产函数形式,应用更加方便。更多还原

【Abstract】 Data processing was researched when there exists negative and low-efficient output data in the construction of stochastic frontier model. Data filtering by data envelopment analysis was brought forward, and the empirical results show that the stochastic frontier model constructed by the filtered data can keep the order of evaluation score of decision making unit consistent with that of data envelopment analysis, and it is more applicable.更多还原
