Efficiency Assessment of Thai Energy Industries: Using Rational Two-Stage DEA

Article Preview

Abstract:

Energy industries have a high potential to contribute the Thai economy. In exploring operating activities, concept of data envelopment analysis (DEA) is led to appropriately consider technical efficiency. Since the whole process of firms can be separated into two sub-processes; production acquisition and profit earning, this research aims to assess the cause of an inefficiency for the 24 energy companies by using rational two-stage DEA. Cross section data was obtained from the stock exchange of Thailand in 2010. The empirical results showed that the average score 0.7592 of the production acquisition was higher than the average score 0.3376 of the profit earning, implying that the inefficiency for the whole process was caused by the second sub-process. In addition, BCG matrix provided beneficial strategies for a firm’s manager to improve a business performance in order to be the leader of energy industries.
