台灣自1980年代以來，興起了一波波的社會運動風潮，在這樣的歷史脈絡下，族群運動成為其中的一環。客籍菁英有感於自身語言文化所處的不利地位，乃透過社會運動的方式，提出訴求。二十多個年頭過去了，這些運動所造成的後果，可見的部分是官方族群政策的擬定與執行，不可見的部分則在於對於客家族群認同的文化要求。這類的文化期待隱含著血緣與認同的合一性，並且對於「怎麼做才合乎客家族群身份」，也有著本質化的想像。首當其衝的便是面對這些要求的客家年輕人。 　　然而，本文並不預設客家年輕人「天生」就應該有客家認同，或者應該要對客家「建立」認同感，而是以一種社會建構的觀點，試圖去理解已經觀察到的經驗現象：社會中對於客家的文化想像，是如何被建構起來的？而時常被這些客家文化框架要求的後生客家人，作為被框架要求的主體，他們如何去理解自身的客家經驗？透過本研究，我們發現後客運世代的客家人正處於某種歷史現實之中。他們的客家身份或輕或重地對他們的生活產生不等的影響，而他們的客家文化認同，也沿著世代、地域的軸線而產生分歧，然而，他們現階段所面對的客家文化期待，除了是一種同質化的文化要求，同時也是一種強調傳統卻又包含突兀創新的客家建構。這些要求所形成的文化框架，脫離了日常生活的層次，也窄化了人們對於客家的想像。因此，本文認為，唯有對客家抱持著開放性的文化想像，將差異納入思考，對於後生客家人也才能有更為務實的理解。 / There have been a lot of discussions about the ways how “the Hakka” or “Hakkaness” could be or should be understood and performed ever since the Taiwan Hakka Cultural Movement occurred in the late-1980s. It is implied that, with certain cultural imaginations, the Hakka would develop a new form of ethnic identity. Consequently, members of the Hakka people, especially those of the younger generation, have often been required to live a life that meets these imaginations and expectations. 　　This thesis aims to examine the historical-cultural process whereby the identity of “Hakkaness” has been culturally and socially constructed and to explore how the younger Hakka members born after the Hakka Cultural Movement have been interacting with these constructions. A contrast between the lifestyle expected or suggested in accordance with “Hakkaness” on the one hand and the life world experienced by the post-movement generation on the other is highlighted. Regional and generational differences of the “imagined” Hakka communities are discussed as well.
