摘要: 有别于其它计量分析工具,本文尝试以资料包络分析法 (DEA) 来评估非
营利性组织-医院之经营效率,并对 DEA理论、演进及改良作一番探讨,
同时印证学者们的各种权数设限方法,及创新一种从作者实证分析经验中
所得知的权数设限方法-倍率向量绝对设限法(Assurance weight
vector's flexible space of absolute bonuding,AFSAB)。非营利组织
之绩效评估常为多元准则且不易量化,同时在实证上其投入产出间之函数
关系并不显着,此时若以参数估计法来评估其效率,即产生实质上的困难
。由于 DEA方法具有良好的客观评估特性,委实为评估非营利组织绩效之
一有效方法。 DEA模式中之权数,代表该观测点对参考变动空间之"法向
量",也 "隐含"着各投入产出项对整体效率值之贡献程度,由于每一生产
要素有其固有禀赋,若存在任一权数值为零之情况,将造成在经济学上或
管理功能意义上无法解释之情形。为改善上述现象,本研究以市立医院经
营效率之评估为例,运用 DEA效率评估模式来说明,权数若不加以设限,
将使效率分析产生错误,甚至误导管理决策,并希望后续学者在运用 DEA
模式评估组织绩效时,应将权数设限之变动范围对整体效率之影响,严予
纳入考量。
Unlike conventional approaches for evaluating organization
efficiency, a developed mathematical programming technique,
Data Envelopment Analysis(DEA), is able to handle multiple
inputs and outputs simultaneously without assigning arbitary
weights and does not require the use of homogeneous measurement
units nor a prespecified functional relationship between
inputs and outputs, especially in not-for-profit entities. This
paper applies DEA to the assessment of the performance of
Taipei regional hospitals and suggests a conceptual framework
for the treatment of factor weights in DEA. Then,it develops
and and presents alternative methods to limite the ranges
within which these multipliers are allowed to vary. This
research also provides a new approach for controlling factor
weights, named AFSAB by author. All of these methods
involve additional information which is taken into the
analysis in the form of bounding constraints and different
objective functions. Finally, the implications of the various
approaches is discussed below.
