本研究目的在探討認真休閒、社會資本與場所依戀三者之間的因果關係,並檢視社會資本的中介效果。本研究不同於以往從個人與遊憩地互動的觀點討論場所依戀,而專注於探究「人與人」的關係—社會資本是否在認真休閒與場所依戀之間的關係扮演著中介的角色?亦即在探討「人對場所」產生情感連結之前,「人與人」互動所產生的影響程度。研究結果顯示:(1)登山健行者之認真休閒特質對社會資本具有直接且正向的影響;(2)登山健行者之社會資本會正向影響場所依戀;(3)登山健行者認真休閒特質愈明顯者,其對場所依戀的程度愈高;(4)社會資本在認真休閒與場所依戀之間的關係扮演著中介的角色,即認真休閒除可正向直接影響場所依戀外,也可透過社會資本的中介而影響場所依戀。 This study investigated the relationship among serious leisure, social capital, and place attachment and also examined the mediating effect of social capital in the relationship. Unlike previous studies which discussed place attachment mainly from the perspective of human-to-place interactions, this study focused on human-to-human relationships to explore whether social capital really mediates the relationship between serious leisure and place attachment. In other words, this study attempted to find out how much people are affected by "human-to-human" interactions before their "human-to-place" emotional bonding is formed. Results showed: (1) mountain hikers' serious leisure characteristics have direct and positive effects on their social capital; (2) mountain hikers' social capital has positive effects on their place attachment; (3) mountain hikers with stronger serious leisure characteristics tend to have stronger place attachment; (4) social capital mediates the relationship between serious leisure and place attachment; that is to say,serious leisure can not only positively and directly affect place attachment but also indirectly affect it through social capital.
