Integration of network data envelopment analysis and decision‐making trial and evaluation laboratory for the performance evaluation of the financial holding companies in Taiwan

摘要

>Data envelopment analysis (DEA) has been constantly used to measure the technical efficiency of decision‐making units (DMUs). However, the major problem of traditional DEA methods is that they do not consider the possible intermediate effects. Recently, many papers have applied network DEA models to evaluate the efficiency scores. However, the linking activity of DMUs is still hard to be recognized. Hence, we employ DEMATEL to obtain the linking activity of DMUs. Our empirical research shows that the proposed method can soundly deal with the purpose of identifying the relationship between variables and derive the reasonable result in network DEA.
