國內民眾長期深受詐欺電信犯罪侵害，不單受害人數最多且是損失金額最高的經濟犯罪，自前陳水扁政府至現在的馬政府，都將防制詐欺電信犯罪案件作為政府的施政重點，以跨部會的組織主導，研議預防及偵查的手段防制。然而，詐欺電信犯罪案件發生率不減反增，竟演變成為臺灣十大民怨之一。檢討是類案件偵辦瓶頸，都指向係員警未能跨境查緝大陸「詐欺電信機房」及主嫌到案所致。詐欺電信犯罪集團憑藉著不被橫渡的海峽屏障，在日益富裕且電信網路發達的大陸，建立起發收詐欺話務之「詐欺電信機房」，此等機房遂為詐欺首謀之指揮中心。 隨著馬政府上臺，兩岸和解共生局面建立，擱置了主權爭議，簽訂了「兩岸共同打擊犯罪及司法互助協議」。然而，兩岸警方單憑文書及電訊協調辦案，是無法有效壓制以VOIP網路電話為中介犯罪之隱匿詐欺電信犯罪集團，必須由國內警方跨境與大陸警方合作，以「詐欺電信機房」為主要剷除標的，方能達到有效將兩岸主嫌共犯一網打盡、查扣作案工具，贓款、降低詐欺話務及人犯順利遣返接受司法定罪等共同打擊犯罪之核心目標。

自兩岸於1987年開放探親以來，隨著兩岸頻繁的交流，跨兩岸性的犯罪活動，如販毒、詐欺、人口販運等犯罪亦日趨嚴重，特別是近年來出現有別於以往傳統詐騙手法的新型態詐欺犯罪—以電話、網路為中介物的「電信詐欺犯罪」，大肆橫行於兩岸，為害兩岸治安最深，是類犯罪不斷翻新手法，巧藉各種名目詐騙民眾獲取不法暴利，造成極嚴重的社會成本付出。過去，兩岸共同打擊犯罪機制，僅有「金門協議」及其他非正式管道，以為合作打擊犯罪的依據，因「金門協議」的內涵不足致使成果有限。隨著政治氛圍的改變，兩岸終於2009年4月簽署「海峽兩岸共同打擊犯罪及司法互助協議」，為兩岸共同打擊犯罪奠定了新里程碑，惟分析其內容並與「駐美國台北經濟文化代表處與美國在台協會間之刑事司法互助協定」比較，可以發現尚有許多問題亟待解決。本研究藉由分析現行兩岸共同打擊犯罪機制，並提出問題及建議，以強化兩岸共同打擊電信詐欺犯罪的力道。 / Since 1987 Taiwan and Mainland China allowed people visited opposite side, cross-strait crimes such as smuggling drugs, fraud and human trafficking have become more and more serious as both parts frequently contacting with each other. Recently, new type fraud which is different from traditional fraud spread around and critically damage social security, especially telecom fraud by telephone and internet being the mediators. By using multiform excuses, these kinds of crimes continuously renovate to cheat innocent people and obtain huge illegal money, so that they cause a great loss of social. In the past, there were only Kinmen Agreement and the other unofficial channel as the basis in the cross-strait crime-fighting mechanism. However, Kinmen Agreement was too narrowed its coverage to limited in its results. With the political atmosphere changes, each part finally signed “Cross-Strait Agreement on Joint Crime-Fighting and Judicial Mutual Assistance” in April, 2009. This is the new milestone of cross-strait crime-fighting cooperation mechanism. As analyzing it and comparing it with “Agreement on Mutual Legal Assistance in Criminal Matters between the Taipei Economic and Cultural Representative Office and the American Institute in Taiwan”, we found there are still some obstacles need to be resolved. This study offers some questions and advises in order to strengthen the cross-strait telecom fraud crime-fighting cooperation mechanism.

傳統的國家安全威脅之應處，係以確保國家軍事、政治及外交衝突等國家安全問題為目標。隨著冷戰結束後，全球化時代來臨，國際戰略環境的變遷與威脅性質的演變，「非傳統安全」威脅已逐漸取代「傳統安全」威脅。換言之，傳統安全思維僅著重在主權國家的軍事安全層面，非傳統安全則是基於整體人類安全的考量。我國在面對非傳統安全威脅下，如何調整適應環境之變化，以確保生存及發展，已成為當前刻不容緩之要務。 非傳統安全議題相當廣泛，主要包括：經濟及金融安全、自然生態環境安全、網路資訊安全、大規模殺傷性武器擴散、疫情傳播、恐怖主義、跨境犯罪、走私販毒、非法移民、海盜、洗錢等。中國大陸對臺威脅亦包含傳統與非傳統安全威脅性質。傳統安全係以軍事戰略威脅為主，非傳統安全威脅則來源多元、形式多樣，所呈現以走私、海盜、偷渡、偽造貨幣、詐欺、洗錢等跨境犯罪最為顯著， 本論文將探討兩岸共同打擊跨境犯罪背景發展，並分析兩岸交流衍生之大陸民眾非法來臺所呈現之態樣與現況，闡明我國所面臨的非傳統安全威脅，希冀由相關資料分析比較，藉此驗證現行實務面執行運作成效，並針對實務運作所面臨之困境提出研究建議，供相關單位參考，建立一個兩岸和平安全的互動環境。 / The aim of dealing with the traditional threats to national security is to ensure the national security in the aspects of military, politics and diplomacy. After the end of the Cold War comes the era of globalization, international strategic environment changes as well as the substantial of threat evolves. As a result, “non-traditional security (NTS)” threats have gradually taken the place of “traditional security” treats. In other words, the concept of traditional security only focuses on the aspects of military security of a sovereign state, whereas the consideration of non-traditional security is based on the general human safety. While confronting with threats of non-traditional security, it’s crunch time to make adjustments and adaptation so as to ensure existence and development of Taiwan. The issues of non-traditional security are extremely wide-ranging, mainly including: economic and financial security, ecological and environmental security, information and network security, the proliferation of weapons of mass destruction (WMD), the spread of epidemics, terrorism, transnational crime, narcotics and smuggling, illegal immigration, piracy, money laundering, and so on. The threats to Taiwan from China include traditional security threats and non-traditional security threats. The main threat of the traditional threats is military hostility, while non-traditional security threats stem from various sources and come out in multitudinous forms, especially in the fields of transnational crime such as smuggling, piracy, stowaways, currency counterfeiting, fraud, money laundering, etc. This study discusses the background and context of the cross-strait joint fight against transnational crime, and analyzes the current situation and patterns of illegal immigration of the people from Mainland China resulting from the cross-trait exchanges, as well as explicates the non-traditional security threats confronted by Taiwan, whereupon, in the hope of examining the practice performance by means of comparative analysis of related materials, proposed suggestions and strategies for these predicaments are finally concluded as a reference to the competent authorities to build a peaceful and secure environment for cross-strait interactions accordingly.
