| Summary: | 碩士 === 長庚大學 === 企業管理研究所 === 94 === After financial holdings have founded in Taiwan, how to find out the bench mark financial holdings is attached importance to the government organization. We chose the Data Envelopment Analysis (DEA), Principal Component Analysis (PCA) to measure the operation efficiency of financial holdings, and compare their consistence.
In this paper a ranking method is presented within the DEA. Based on the super efficiency ranking method which ranks only the efficient units, we used DEA supper efficiency multistage ranking, G/DEA presented by Hadad et al. ( 2003 ), ranks the inefficient units and efficient units.
The other ranking method is presented by Premachandra（2001）, who describes a joint use of DEA and principal component analysis (PCA) in ranking of decision making units. But Premachandra（2001） used only DEA supper efficiency to rank the inefficient units and efficient units. We improve Premachandra（2001）’s method by using DEA supper efficiency multistage ranking to rank the inefficient units and efficient units.
Through the two ranking methods to evaluate the performance of financial holdings in Taiwan, we find that there exists consistency between the rankings obtained from G/DEA and PCA.
