An application of super-efficiency and tobit method for financial efficiency analysis of food industrial companies in Taiwan

摘要

Concept of super-efficiency data envelopment analysis (DEA) is used to extensively assess a technical efficiency and to benchmark the operative efficiency. This research adapted super-efficiency model as well as Tobit regression to analyze the financial efficiency of food industrial companies in Taiwan. The objectives include an initial assessment followed by the determination of the factors affecting the financial efficiency. This study uses cross-section data collected in 2009 from 22 food industrial companies in Taiwan. Firstly, the super-efficiency model is used to identify the efficiency scores. This allows the ranking of those companies to be used as a base of the production function, which considers input used and output produced. Secondly, the Tobit regression is employed to analyze the factors affecting the financial efficiency. Three factors are considered in the research; internal boards, external boards, and shareholders. The empirical result shows that all factors have different significance at various confidence levels. The result indicated that the firms' financial efficiency can improve by increasing the number of internal boards and shareholders. On the other hand, many external boards can decrease the financial efficiency significantly.
