Summary: | A popular technique to measure efficiency comprise of a two-stage approach, consisting Data Envelopment Analysis (DEA) with Tobit regression. Since the highest efficiency score of DEA is censored at one, this method has some weakness of covering additional information at the upper bound of the efficiency scores. This research adopts the super-efficiency model as an alternative of DEA-based approach for a two-stage efficiency measurement. The super-efficiency is quite different from the traditional DEA model because its bound is extended more than one. The cross-section data of information and communication technology companies in 2010 was conducted from the Department of Internal Trade in Thailand, studying how the operating efficiency scores are affected by the number of the internal boards, external boards, stakeholders, patents, research and development, established years, subsidiaries, and products. The empirical results of super-efficiency offer the advantages over the traditional DEA. It also provides some useful information to improve the operating efficiency scores. |
