||The impact of globalization and the increasingly close cross-strait exchanges has contributed to the heavy flow of people and foreigners at the borders, leading Taiwan into the trend of “the internationalization of population”. Since the government started the open cross-strait exchanges policy in November 1987, a growing number of mainland Chinese people has come to Taiwan for intermarriage, visiting their relatives, sightseeing or engaging in professional activities by means of mini three links routes and charter flights, etc. These have also brought along with the violation of the laws and violation of provision. Divided only by the Straits of Taiwan, the mainland China and Taiwan are of the same race and share the same language. Thus, the common illegal activities like smuggling, hypocrisy marriages, fake relatives, fake documents and other illegitimate activities have been used to enable them to arrive in Taiwan. As a result, there have been many cases of violation of law (provision) which have caused great impact to the level of public order and social morality and even national security and thus can not be ignored.
Since 2002, the government has opened up the first category of mainland Chinese people to Taiwan for sightseeing. Initially, hundreds of people arrived daily. However, when the policy began to be formally implemented on May 1, 2013, the number of people has reached 10,220 daily. Behind this booming economy of tourism, there are some concerns as some problems have been caused by the growing number of mainland Chinese people to Taiwan containing the first category and the free independent travelers (FIT). For example, some of them run away from their tour groups and overstay illegally. Besides, some work illegally or are involved in illegal activities on the pretext of having the medical cosmetology or health examination combined with sightseeing and free independent travel. Facing this kind of diversified patterns, it is time for the government to deliberate a positive and effective security management system on this important issue.
In this paper, I would like to deliberate the political and economic effects of mainland tourists to Taiwan, the historical development of cross-strait travel, the existing laws and security management system. Also, through the analysis of runaway mainland tourists and illegal overstay, it enables us to understand the social security and the negative impact of the national security. At the meantime, we can monitor mainland tourists with high-risk factors and offer suggestions on the existing management system in order to reduce the damage and threats to the nation. When facing the impact of globalization and challenges, we hope to find out the future tourism positioning and good foundation of growth in Taiwan
