2004年10月，第五屆亞歐會議在越南河內舉行，本屆亞歐會議可以視為歐洲與亞洲兩大區域的結合。亞歐會議雖然確立了「政治對話、經濟合作和文化交流」三大領域的合作關係，但是到目前卻仍然停留在相互對話及磨合的階段，連最初步的雙方共組自由貿易區都無法達成共識; 另外，不論從經濟面向或是政治面向來檢視，亞太地區仍然是東亞國家主要貿易往來的主體，同時亞太地區已經存在著亞太經合會的對話管道，甚至東亞地區的東協加三也正在逐漸成形，成為東北亞與東南亞的主要交流管道，因此，在沒有共同經濟利益的基礎之下，亞歐雙方在整合議題上實在很難找到契合點。在這種情況下，本文嘗試從國際建制的角度來分析亞歐會議之下經濟議題的構築，並測試其在經濟議題整合的深度，接下來再從經濟議題結構的脆弱程度來分析亞歐會議將來會面臨到的主要困境。

The 5th ASEM took place on October 2004 in Hanoi, Vietnam. Although ASEM is an informal forum, it was one of the most important cross-continental regime. Though the forum establishes the structure of “political dialogue, economical cooperation, and culture interflow”, the process still lodges on dialogues of two sides, even in the free trade area that was co-established, consensus is rare. 

In addition, from both political and economical aspect, the Asian-pacific region still is the mainframe of East Asian trades; the ASEAN Plus 3 gradually forms and becomes the communicating tube between Northeastern and Northwestern Asia. Therefore, before reaching for a shared economical interest, Europe and Asia both sides will be difficult to find a common stand point. Under such circumstance, this study tries to analyze the structuring of economy issue of the ASEM, meanwhile tests the depth of economy integration, and then from the aspect of structure of the economy issue and its fragility to analyze future predicament the ASEM will face.
