本文旨在探究衝浪者自我呈現動機、休閒投入與遊憩專門化之關係。本文係以立意抽樣進行問卷調查，藉由衝浪相關社群與社團邀請臺灣地區北、中、南與東部海岸之衝浪者參與此次調查，共計回收有效問卷251份。研究結果顯示，自我呈現動機正向影響休閒投入。此外，自我呈現動機與休閒投入亦會正向影響遊憩專門化。再者，休閒投入部分中介自我呈現動機與遊憩專門化之關係。場域管理單位與活動推廣組織應可藉由實體環境、社會互動與線上社群激發衝浪者自我呈現動機，藉以促進休閒投入與遊憩專門化之程度。

The purpose of this study is to investigate the relationships among the self-presentation motivation, leisure engagement, and recreation specialization of surfers. The purposive sampling method was used to collect data. Surfers from the northern, western, southern, and eastern seashores of Taiwan were invited through online social networks to participate in this study. A total of 251 valid samples were finally collected. The results of this study indicated that self-presentation motivation has a positive effect on leisure engagement. Furthermore, self-presentation motivation and leisure engagement also have positive effects on recreation specialization. Moreover, leisure engagement partially mediates the relationship between self-presentation motivation and recreation specialization. Seashore management units and activity promotion organizations may utilize physical environments, social interactions, and online communities to stimulate the self-presentation motivation of surfers as a way to promote the degree of leisure engagement and recreational specialization.
