     網路電路(Internet Telephony,簡稱IT)在國際或長途電話的低成本優勢引起消費大眾及電訊業者廣泛注意且產生新的應用與服務機會。因此業者若對消費者的潛在需求與需求預測詳加瞭解,將有助於行銷策略之研擬。所以,本研究將網路電話潛在消費者市區隔成「擁有電腦者」與「非擁有電腦者」二個市場。網路電話選擇行為決策變數為「費率」、「操作時間」、「聲音傳輸品質」、「塞機情況」、「附加功能(如視訊、檔案傳輸等)」五個變數。並以敘述性偏好法針對消費者選擇國際/長途電話媒介選擇行為進行實證研究。研究結果顯示,在「非擁有電腦者」市場模式不顯著。在擁有電腦的區隔市場中「費率」、「聲音傳輸品質」和「塞機狀況」屬性有顯著差異。因此可之網路電話服提供者產品策略應著重在聲音傳輸品質和塞機狀況的解決上。本研究並模擬10個的價格策略與析其市佔率的變化,結果發現如果網路電話機價格價格便宜且消費者熟悉IT的話,網路電話機有30%。
     Recently, Internet Telephony (IT) has become an increasingly popular telecommunications service due to its low cost. Accordingly, this study uses the stated preference method to analyze demands in the IT communications market and provide product and price strategies to Internet service providers. For this, I divide the market into two segments, “owning a computer” and “without a computer” groups. Furthermore, five IT attributions were chosen: voice transmission quality, calling rate, operation time, traffic jam (line busy) and additional features. The results indicate that the multinomial logit model was not significant in the “without a computer” group. Whereas calling rate, voice transmission quality and traffic jam are the three critical factors in the “owning a computer” group. The product strategy of VoIP providers should emphasize increased voice transmission quality and solving the problem of traffic jams. This study also formulates ten different price strategies and estimated their market shares, finding that IT advice had more than a 30% market share if IP devices were cheap and users are familiar with VoIP.
