在面對大陸低廉的生產成本競爭下，台灣許多中低階產品之生產製造已逐漸移往大陸，這是比較利益法則下無法避免之趨勢，因此就台灣廠商未來之長久發展考量，強化行銷或設計研發能力是必走的途徑；由於台灣本國市場規模較小，加上新產品之研發設計成本不斷提高，因此如何能成功的將新產品導入海外市場銷售，以增加整個產品之總收益為企業值得思考的課題。 　　無線通訊產業為台灣目前十大新興產業之一，而且就台灣廠商現有資源來看，如果要成功的推出新產品在海外上市，在通訊產業中若考慮技術標準掌握度及成本競爭力以無線通訊終端產品之成功機率較高。此外，由於台灣廠商較缺乏新產品在海外上市之經驗，因此本研究希望藉由最低之最終總交易成本觀念之分析探討，幫助台灣廠商在擬定新產品海外上市策略時，在有限資源使用下將產品、通路、推廣組合與定價策略做最有效之搭配，以提高成功機會。 　　本研究之研究架構先以學理基礎為背景，再配合國內外案例做深入個案探討，針對將新產品行銷至國外市場之廠商，先經由文獻探討、資料收集後，再藉由與負責個案產品上市之相關人員進行深度訪談，將結果加以分析、歸納與整理，讓理論架構與實際狀況做一印證並從中歸納出對廠商之新產品上市行銷策略建議，供國內無線通訊廠商在進行新產品海外上市時之參考。 / As facing the low-cost competition from China-made products, lots of manufacturers of low-to-middle tier products have moved their production basis to China. It's the trend and not be avoided based on the conclusion of reference. Therefore, to enhance the capability of Marketing and Research & Development are becoming a crucial point. Furthermore, the issue about how sucessfully launch a new product to overseas market in order to raise the total contribution is getting important. That's because the size of local market and high cost of development in Taiwan. 　　The Wireless Communication is one of the growing industries in the world. Based on the current resources what Taiwanese companies have as well as the owned expertise about technology standard and cost competance, the terminal products of wireless communication is most likely to be successfully penetrate to overseas markets comparing with other categories. Besides, lots of Taiwanese companies are lack of experience about launching new products in overseas markets. So, this study is trying to come up with a principle, which is based on the analysis of concept of lowest exchange cost, and to help Taiwanese companies set a proper launching strategy. This strategy will be a best fit from four aspects including of Products, Channels, Promotions and Prices. 　　The structure of this study is started from theory analysis referred to related thesis, then get involved into two practical cases which described how these two companies set their launching strategy, respectively. During the process, the interview with related persons provides a valueable collection of insight. After that, a conclusion is built up and confirmed it with facts from practical cases. This concluded principle could be a valueable reference for Taiwanese companies.
