Abstract:

In order to analyze the operational efficiencies and the influencing factors of telecommunication operators, the method to evaluate the firms with productive efficiency was proposed. The firms’ technical efficiencies, pure technical efficiencies, scale efficiencies, and the types of scale efficiency were analyzed with the data envelopment analysis (DEA). And the impacts of environment variable on the productive efficiency were analyzed also by using Tobit regression method. Finally, some suggestions are given to maximize productive efficiency. It is shown better to evaluate by efficiency since it avoids the weakness of the evaluating while focused on “quantity”.

Key words: data envelopment analysis, technical efficiency, scale efficiency, Tobit regression, Malmquist index
