| Summary: | 碩士 === 國立成功大學 === 電信管理研究所 === 95 === Taiwan’s fixed network market has been gradually liberalized since 1987. The new operators ETB, TFN and NCIC got their licenses in March 2000. This change would create a new generation in liberalization and broadband transmission, indicating Taiwan’s fixed network market is being toward to complete liberalization. However, the market is still high concentration according to the evaluation using the index of Concentration Ratio N (CRN) and Herfindahl-Hirschman Index (HHI). By the way, the revenue of Taiwan’s fixed network market is estimated to 1,044 hundred million in 2006. Of the revenue, CHT has 84％ revenue, the other companies have only the revenue of 16％.
The purpose of this research is to find out the reasons why the fixed network market in Taiwan is still highly concentration after complete liberalization. We use in-depth interview among different authorities of fixed network operators, and refer to the liberalization framework of World Trade Organization (WTO) Group on Basic Telecommunications (GBT) to find out the factors causing the concentration phenomenon.
From our findings, there are four reasons causing the high concentration in Taiwan’s fixed network market. The first reason is the unique characteristics of fixed network market such as high construction costs for last-mile local loop. Second, the demand in fixed network market is almost satisfied. Third, from the supply factor, the number of operators permitted by government is too many to make the new operators have benefits. Finally, the incumbent operator (CHT) has some competition tools to keep their market share when the fixed network market is open.
