戶外遊憩活動參與者基於專精特定活動的需求，對於場所會產生依戀的情形，故本研究旨在探討遊憩參與者其遊憩專門化對場所依戀之關係，並更進一步驗證社會支持之調節效果。以臺灣自行車騎乘者為研究對象進行問卷調查，共獲得598份有效問卷。運用偏最小平方法就測量模式、結構模式及調節效果進行分析。研究結果顯示：一、自行車騎乘者的遊憩專門化會正向影響場所依戀，且主要貢獻來自於「技巧與知識」構面。二、經多群體分析，社會支持在整體模式中扮演調節角色，亦即當自行車騎乘者之社會支持越高，其遊憩專門化對場所依戀的影響越強烈。本研究結論：透過提升自行車騎乘者之專門化程度（如：騎乘技巧、單車知識、對單車活動之情感承諾、騎乘頻率等），均可增加騎乘者對於活動地點的依附程度；在模式中加入社會支持此調節變數的考量時，變數間的關係會有所變化，亦即當透過休閒教育等方式提升周邊他人對於自行車活動的社會支持，可強化遊憩專門化對場所依戀的影響程度。最後，藉由研究結果提供戶外遊憩管理單位在經營管理之參考。

Participants in outdoor recreation activities tend to be attached to the site due to the need of specialization for specific activities. The purpose of this study was to examine the relationship between recreation specialization and place attachment, and also to verify the moderating effect of social support. The research data in the form of 598 valid questionnaires were collected from cyclists in Taiwan. Partial least squares (PLS) method was used to conduct an analysis of the measurement model, the structural model, and the moderating effect. The result shows that (1) The recreation specialization of cyclists positively affects their place attachment, which is mostly contributed by the dimension of skill and knowledge. (2) From the multi-group analysis, it is clear that the social support plays a moderator role in the model, that is, the higher level of social support is the stronger influence of recreation specialization toward place attachment. This study concludes that place attachment of cyclist can be strengthened with enhancement of the specification degree of cyclists (i.e., riding skills, knowledge for bicycle, psychic commitment to cycling and riding frequency, etc.). The relationship between variables has changed, when the model take into account the social support moderating factor. In other words, leisure education not only increases the social support toward cycling, but also intensifies the impact of recreation specialization on place attachment. The results of the study could be used as a reference for the administration of outdoor recreation on management strategies.
