Is There Any Difference of the Operating Performance between the Innovative Security Companies and the Ordinary Considering Exchange Risk? A Meta-NOM-NHybrid DEA Approach

In this paper, to evaluate the performance of two types of security in china, we propose a series of model, such as NOM-Hybrid DEA model, Group-NOM-Hybrid DEA model, Meta-NOM-Hybrid DEA, TGRO revised model, DEA scores computed in different kind variable with different technical level. This model is laid emphasis on the most crucial elements of security institutions, the risk vectors. In doing so, we positively attempt to answer the question whether there is a significant deference about the operational efficiency between the innovative securities companies and the ordinary or not, in the case of currency risk. In addition, we analyze the performance of the security considered with the different DEA models proposed, which is differ in the way the negative data is taken into account.
