In addition, as financial holding company (FHC) securities, non-financial holding company (non-FHC) securities and foreign company (FC) securities face difference in frontier, we use the concept of efficiency gap, proposed by Battese and Rao (2002) to conduct further analysis. The results show on average after the Financial Crisis impacts: First, FHC securities are better than non-FHC securities and FC securities in efﬁciency change (EC), the scores is 1.004.
