本文分析廣東沿海城市台商慢速壘球聯盟的發展，說明休閒行為緊密聯繫於族群、階級、性別等社會生產關係。這些社會變項與休閒運動之間，並非呈現靜態的對應，而是呈現複雜的劃界、跨界與再劃界的動態。跨國遷移使慢壘運動在對岸和在本地體現不同的社會學意涵。對岸台商基於特殊慣習，透過慢壘這個國球實踐展現秀異的邏輯，使台商慢壘場域演變成純淨的族群階級空間。台商慢壘場域內部也體現休閒資源分配的緊張性，一方面是不同休閒運動的正當性鬥爭，另一方面是對台商這個特殊團體的定義協商

Based on the analysis of the development of Taishang (Taiwanese businessmen) slow-pitch Softball Leagues in Guandong, China, this paper explains how leisure activities are linked with social productive relations such as ethnicity, class and gender. The correspondence between the aforementioned social variables and leisure activities is not a static state, but a dynamics that demonstrates continuous making, transgressing, and remaking of social boundaries. Against its transmigrant background, Taishang, with exercise of a Taiwanese national sport, creates sociological meanings different from those produced in Taiwan. Taishang always tries hard to demarcate or remake lines between mainlanders and themselves. With their specific habitus, Taishang practices this quasi- national sport that embodies the logic of distinction and makes the field of Taishang's slow pitch softball a pure space of ethnic Taiwanese. It illustrates not only the tension of resource distribution concerning leisure activities between Taishang's fraction but also the struggle for legitimacy in different sports and the definition negotiation of Taishang as a specific group.
