自2014年政府提出金融業「打亞洲盃」的政策願景後，金融業開始更為積極的構思如何佈局東南亞，其中證券業因國內市場經營不易，證券市場逐漸萎縮，因此更急需往國外發展，開拓業務範圍。唯東南亞國家多因語言差異、風俗習慣隔閡，及資訊取得不易等因素，台灣證券商在缺乏資訊的情況下難以判斷應佈局於何處，以及應如何佈局，故本研究藉由蒐集各國文獻及資訊之文獻分析法，統整分析後提出台灣證券業佈局東南亞可行的策略、方向，從最基礎的經濟環境切入，分析潛在市場規模大小和未來成長潛力，找尋合適的佈局標的，擴大經營版圖，擺脫台灣證券市場萎縮之困境，並建構出適合台灣證券業之國際化經營發展策略，期能與國外證券商分庭抗禮，乃至於發展為亞洲區域型券商。 / Since Taiwan government announced that financial sectors competing across Asia in 2014, Taiwan’s financial institutions has worked more aggressively on how to reaching out to Southeast Asia.
