|Abstract: ||2008 年馬英九政府執政後，兩岸交流無論是經濟或是文化上開始互動，不僅是常態性的互動，在次數上亦較以往頻繁，但回想過去，兩岸之間在政治、軍事或外交上仍存在爾虞我詐、互挖牆角之敵對狀況，除此之外，中國大陸近年來在經濟發展上日益茁壯，大陸人民來臺從事與許可目的不符之工作或活動，甚或中共有計畫偽裝派員進入國內進行滲透、情蒐事件，未曾間斷過，隨著政府新政策開放，就有新的非法入境管道。|
After President Ma was in power in 2008, Cross-strait exchanges start to interact not only in economic but also in cultural aspect, and the numbers of the times of the interactions are more frequent than ever. But in the past, two sides in the politics, military or diplomacy are still in a hostile situation. Moreover, China’s economic development has increasingly grown in recent years. Mainland people coming to Taiwan engage in work or activities with the unapproved purposes or China even assign disguised staff to enter Taiwan to do infiltration, and intelligence gathering event, and never stopped. With the opening of the new policy of government, there will have new illegal immigration ways.
The government fully opened up Go-traveling mainland tourist coming to Taiwan since July 28, 2011. From an economic perspective, there is a positive effect for the Taiwan economy indeed. With the rapid changes of the situation cross-strait relations, the both side exchanges of type, pipeline, and levels are constantly upgrading expanding. Cross-strait exchanges order towards normalization; meanwhile, and the cross-strait of the interactions causes many problems. It has long been different from the back in the past. Behind the economic development of the government, few Mainland tourists by the name of sightseeing coming to Taiwan engage in work or activities with the unapproved purposes, made a great impact on national security and public security. Hence, before the support measures be ready, the process of opening up should not be rush. In the meanwhile, the government should strengthen the security management system of the authorities, such as the capacity of investigation before arrival, the contact after entry, provisioning work and the investigation energy of the security organizations. The point of this study is to maintain cross-strait peace and national development on the basis of the fine cross-strait relations.
