第七章 . 結果分析與討論
第三節 未來研究
在未來研究，有兩大方向，可以與本研究啣接。
1. IPTV 發展因素的探討。本研究僅將 IPTV 視為 DSL 多元化發展之一，
並未深入分析IPTV 發展的由來。但是，DSL 業者卻視 IPTV 為必打的 戰役，因為IPTV 具有互動性、跨國性、且更重要的是可擴大 DSL 業 者的固有市場。IPTV 發展最快速的國家之一是韓國，Shin (2007) 認 為影響韓國 IPTV 主要因素為產品本身的特色（及時、互動、加值，
相容性等）、成本、人口素質、政府的干預（供應端與需求端）、政府 對大企業（chaebol，或譯為財閥）的支持態度等，但是，實務導向的
Point-topic (2006b) 則認為網路品質及用戶終端設備成本、各國獨特市 場條件（衛星與有線電視普及程度）、DSL 業者價格戰的空間、IPTV 串流訊號與既有電視結合的服務問題、未來的技術未定論，皆可能影 響 IPTV 的發展。因此，一項項探討並分析，建立利害關係架構，是 可行的研究方向。
2. DSL 業者在面對毛利率下滑的寬頻市場，如何留住用戶？這部份研究 並不容易，因為業者為了吸引新用戶，其促銷手法已經由原本與DSL 商品具互補性的商品或服務（例如：無線路由器、筆記型電腦、讀卡 機等），延伸至異業結盟的商品或服務（例如：旅遊或購物禮券），林 林總總的促銷，已經摧毀既有顧客的忠誠度。但此種促銷方式究竟是 驅逐顧客或是招徠顧客？是否存在讓 DSL 業者纏住用戶的好方法？
其實 BT 將固接電話、行動電話、寬頻服務整合為家庭通訊服務的中 樞，或是美國Verizon 推出的 iobi home，都可能是未來研究方向之一。
