兩岸關係研究在開放政策的導引下，自過去以共黨體制與理論研究，轉為更務實的經濟和文化研究，兩岸社會和人民透過頻繁交流瞭解彼此，是目前兩岸關係的重要發展，其中一項趨勢即是大陸年輕學生能在台灣停留，並在一段不算短的時間內深入一般民間生活，這些所謂的「陸生」在來台停留4個月以上的時間內，除了在學校上課，騎單車環島、搭「台灣好行」、搭台鐵、坐公車等等方式，在台灣城市和鄉野間體驗與感受，一部分人更在選舉造勢場合，和激動的選民一起喊凍蒜凍蒜。 根據Allport以來學者對於接觸相關研究文獻的瞭解，群際之間的研究必須考慮接觸的內涵、接觸的過程以及制約接觸的條件等對接觸效果的影響。傳統「接觸假說」認為類似文化背景之群體可透過深度交流接觸達到真正理解溝通，消除群際偏見與隔閡，達到族群融合。 本論文即以上述理論為基礎探討兩岸年輕學子交流的樣態及效，透過量化的問卷與深度訪談，探索這個族群接觸內涵與過程，理解到所謂的「接觸」並不能僅限於「接觸的頻率和時間長短」，也不能僅奠基在語言文化具類似性的基礎上，就達到「接觸假說」所預設的「消除類屬」(de-categorization)或進一步「融合類屬」(re-categorization)。因為族群之間各成員心中存在著「自我類屬」(self-categorization)，想要消融彼此的界線，必須先探索成員對自我類屬的定義，此外還須考慮接觸環境上制度面的制約，從制度面的設計增加群際成員的接觸頻率，才能進一步減少成員的「群際偏見」(intergroup bias)及增進「群際情感」(intergroup emotion)。 / In the leading of open policy, the mainstream of cross-strait studies has shifted from Socialism and Communism to Economy and Culture. At the tide of exchange, Chinese exchange students studying in Taiwan are the most propriate targets to learn about, less sensitive and having deep contact with Taiwan society. According to the related studies like Allport’s, scholars should take the content, process, and constrait of contact into consideration while studying the relations between nation groups. Traditional “contact assumption” assumes groups sharing similar culture background will reach mutually understand through exchange in depth, deliminate bias and barriers between groups. This study has examed the impact of the frequency and time length, the language and culture similarity on contact, knowing that those conditions above are not the only factors to de-categorization or further re-categorization. The members of each group have bared self-categorization in mind. Eliminating intergroup bias and enhance intergroup emotion would play an important part of breaking down the walls between groups. Besides, the goal of institutional design is to make the contact more intensive and to avoid the false contact. The less attractions offered by media to the Chinese exchange students, the less political socialization they will have. So the policy design should be delicate enough to allow those students to take the advantages of curriculums、professors, and schools to reach the goal of social contact between the young generations of cross-strait.
