摘要
利用因子分析和数据包络分析相结合的方法,对我国2010年煤炭采选业22家上市公司的经营效率进行评价。通过因子分析把许多投入产出指标归并成若干个具有明确经济意义的公共因子。再利用DEA模型计算出各个决策单元的相对有效值,分析出哪些公司是DEA相对有效的,并进一步计算出DEA相对无效或弱有效的公司的投入冗余率与产出不足率。并探讨了提高煤炭采选业经营效率的方向和途径。
The relative efficiency of the 22 listed mine companies are studied by factor analysis and DEA method.Many input and output indexes are merged to several indexes with definite significance.Then,the relative efficiency of every decision making unit is computed by DEA method,which can judge if the listed mine companies is DEA relative efficient or not.The excessive input ratios and shortcoming output ratios of every mine companies are also computed.Finally,the direction and approach of improving relative efficiency of the listed mine companies.
