煤炭企业技术进步的评价与对策

将常用于横向比较的静态数据包络分析(简称DEA)方法, 转换成研究对象(如企业或部门)自身在时间上纵向对比的动态DEA方法。通过输入计算指标值, 对动态DEA模型进行求解, 得出技术进步作用的评价指标值, 并逐一加以分析。而且利用DEA有效性概念, 判断企业是否技术有效或规模有效, 对非有效的情况, 计算出实际输入的计算指标值与有效情况下要求输入计算指标值在数量上的差距, 对症下药, 提出解决对策。

The Assessment and Countermeasure of Technological Progress in Mining Enterprise

This paper putout a method of dynamic Data Envolopment Analysis (DEA) of vertical comperision in studying objects themself (example:enterprise or deparatment, ect) that changing from the method of static DEA used in horizontal comparision, with inputing the calculating index ualue and analysing the assessment index value of technological progress.The value of these index is analysed one by one. Using the concept of DEA validity, we can judge if the enterprise is technological validity or scale validity. On the codition of non-validity, we can calculate the distance of real-inputing calculating index value and necessary inputing calculation index value on valid condition. And the solving countermeasure is putouted.
