| Summary: | 碩士 === 國立成功大學 === 電信管理研究所 === 92 === Chunghua Telecom Company has dominated the main fixed line markets until the ban on the markethas been released in the early 2000s.Three privacy-run fixed line companies allowed to join the fixed line markets.But the competition of fixed line between companies is not as severe as the cell phone markets do. Over 90% of city telephone
affairs are still operated by Chunghua Telecom Company. The dramatic factor is that the popularity of city phone usage has reached the required demand after the fixed line is permitted to others’ run, the fixed line company are able to attract new customers who are originally use the service of Chunghua Telecom Company, and the increased budget will be take into consideration while they transfer the original numbers into brand new ones.
Moreover, in light of overcoming the above-mentioned complicated issues, the policy
based on the number portability will kick off in the year of 2005. Telephone users can
keep original phone numbers as if they use another company. In addition, the good
benefits include decreasing the transferred budget and appealing new fixed line company
fairly to compete with Chunghua Telecom Company. Therefore, the fixed line companies
are willing to provide a great deal of best service quality, lower service charge, as well as
maintain their occupancy.
The major objective of this study is to introduce the number portability technology
and concept at domestic and international markets, review the related references, and
stipulate the efficient and valuable evaluation flow. Domestic studies concerning captioned
issues published are still insufficient. The evaluation of numbers portability projects has
been carried out by U.K. and H.K in the early of 1998.This thesis adopts thesis
frameworks and adjusts several evaluation items. In the evaluation of NP’s user benefit,
fixed line subscribers are sorted into different user types according to the benefits
generated by NP, and the procedures of user benefits’ evaluation and aggregation are then
constructed, via reasonable and feasible sampling methods, date collection is derived from
the questionnaire of fixed line subscribers in Taipei, Taichung and Kaohsiung metropolitan
cities. (The number of effective samples is 385). Finally, considering several scenarios of
NP churn rates, we estimate the net benefit derived from the 10-year implementation of NP
on domestic fixed line market. We hope this thesis can be a concrete academic support for
Bureau of Telecommunication’s NP policy.
The main findings of this thesis can be summarized as follows. The liquidity of
subscribers in fixed line market is relatively low and lower than half of ordinary
subscribers/business subscribers have switched operators. Further, NP increases the
inclination of subscribers to switch operators and thus promotes the subscribers’ liquidity
in the market. In the cost benefit analysis of NP, it will bring at least a N.T. $6,158 million
(and up to N.T. $15,221million) of the present value of 10-year net benefit to every fixed
line subscriber. NP churn rate has a positive impact on subscriber’s net benefit. Therefore,
Bureau of Telecommunications in Taiwan should promptly implement the NP policy to
promote social welfare.
