中文摘要：

全球化影響人口移動、金融經濟、文化交流及資訊流通，也為犯罪創造了有利的條件，全球犯罪活動模式上有了全新的樣貌與型態。組織犯罪從過去傳統黑幫科層制演變成網絡式扁平水平式的組織型態。而跨境詐欺組織犯罪以網絡型的犯罪結構造成民眾與國家巨大損失，他們藉由精細的分工分層化，水平的網絡合作關係，加深了執法機關查緝之困難。因此本研究希望綜合研究發現了解跨境詐欺組織網絡結構與特性及其犯罪手法與組織分工，以情境預防犯罪概念提出有用可行之建言，並對實務查緝方向有所助益。
本研究首先以「文獻探討法」了解組織犯罪之定義以及組織犯罪與環境變遷下的發展趨勢為開端，進而探討以傳統黑幫科層制或網絡水平式的組織犯罪之各項角色結構差異，並逐一建構出網絡型組織犯罪成為現今犯罪組織之主流，亦導出本研究跨境詐欺組織的網絡結構發展主軸；後以情境犯罪預防中日常生活及犯罪腳本理論強化現階段實務打擊詐欺方向。在「次級資料分析法」部分，以近2年（自2015年1月1日至2016年12月31日止）各地方法院判決跨境詐欺有罪判決書進行統整分析，並輔以4名實務偵查人員「深度訪談法」補充判決書分析之不足，以組織犯罪活動三要件：「犯罪人生活型態」、「犯罪團體與網絡」及「主要犯罪行為」三大面向進行跨境詐欺組織之整理與分析。研究發現，跨境詐欺組織猖獗的關鍵在於其網絡式的水平發展，首腦或金主以扁平式的弱連結製造查緝斷點，並以分散及小規模化降低查緝風險，其藉由網路通訊的高匿名性、以及融入日常生活的隱密性更使執法機關難以察覺及預防。
因此在研究建議部分，透過了解跨境詐欺組織網絡及現階段執法機關難以突破的斷點方面提出建言，並分為預防面：（1）以情境預防犯罪理論建構健全防衛網絡；（2）建立中央資訊安全監控機制，制定相關罰則及資訊公開化；（3）公私協力並加以推廣，加強人頭卡及帳戶斷尾機制；（4）加強出入境查核，防止國人出境實施詐騙；（5）持續加強反詐騙宣導警語，提升易被害族群宣導廣度；（6）針對經常性招募管道與處所，加強監控與查訪，減少犯罪誘因。及偵查面：（1）建立大數據共享平臺，解構犯罪網絡重要節點，溯源中介者；（2）提高偵查網絡深度及廣度，追蹤詐欺犯回歸社會之人際網絡；（3）加強我國與國際合作打擊犯罪機制，促進資訊交流；（4）培訓查緝專才，定期培訓與更新專業知能及詐騙情資；（5）中央與地方情資共享，地方諮詢佈建建立資料庫；（6）偵查部門以主要構成犯罪網絡，分工分層化提升查緝精緻度。綜上期能對現階段打擊跨境詐欺有所助益。

英文摘要：

definition of organized crime and connection between crime organization and social changing. Then to discuss the difference between mafia-type and network organized crime. Finally, concludes with how network crime organization has become the main stream type of crime. In the second data analysis section, in order to strength the argument by interview with four detectives, the researcher collected and analyzed guilty verdict documents with regard to fraud cases from district courts in Taiwan in last two years(from 1/1/2015 to 31/12/2016). There are three elements of organized crimes, Includes life style of criminals, gang groups and networks, and main criminal activities. Hope thorough the three aspects can understand more about the arrangement and analysis of cross-border fraud organizations. The study has found that why cross-border fraud organizations are so triumphant, there are key reasons: They full utilize of horizontal cooperation on internets and try to avoid detection by low density connection with member, dispersion and minimization risks, high utilization of anonymity and encryption on using internet and getting into daily life. Therefore, in the research proposal section, through understanding the cross-border fraud network operation and the difficulties of breaking through of law enforcement agencies at this stage, and are divided into precautions and investigation subjects:
1. Prevention subject:
(1)Constructing a strong defense network based on situational crime prevention theory
(2)Establishing a central information security monitoring mechanism, formulating relevant penalties and information disclosure.
(3)Popularizing public and private collaboration, strength the cutting-losses mechanism on false phone users and bank accounts.
(4)Strengthen the immigration and departure check to prevent people from leaving the country to commit fraud crime.
(5)Continuing to strength anti-fraud campaigns on vulnerable groups.
(6)Improving supervision and inspections for recurrent recruitment channels and places to reduce the incentives for crimes.
2. Investigation subject:
(1)Establishing a data sharing platform to deconstruct important nodes of criminal networks and tracing mediators. Create sharing big data and deconstruct the key point to trace agents.
(2)Enhance the depth and breadth of the investigation network, and trace the return of ex-fraud criminals to the social network.
(3)Strengthen international cooperation in cracking down on crimes and promoting information exchange
(4)Regularly training talent and professional agents, and update professional knowledge and fraud intelligence.
(5)Sharing information both central and local law enforcement agencies and establishing database by widely collecting information.
(6)Investigation agencies should be divided into delicate sections by different forms of criminal network, and work in cooperation to promote the accuracy of investigation.
