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.
