本研究以親子旅遊為主題,透過計畫行為理論了解親子旅遊時家長與兒童的環境行為現況與差異,並探討家長與兒童的人口背景、環境態度、主觀規範、知覺行為控制對行為意向的影響及行為意向對環境行為的影響,期許創造美好的休閒環境。以參加過親子旅遊的家長與兒童為研究對象,收集相關資料進行量化的分析探討。 研究結果發現:1.家長方面: ⑴不同年齡和職業的遊客之環境行為和主觀規範有顯著差異。 ⑵遊客不同的旅遊一天平均花費之知覺行為控制有顯著差異。2.兒童方面:不同旅遊次數和母親是大專或大學以上畢業的遊客之環境態度有顯著差異。3.兒童和家長方面: ⑴遊客的「知覺行為控制」和「環境態度」對「行為意向」皆有顯著影響力,而且知覺行為控制的影響最大,而環境態度其次。 ⑵遊客的「行為意向」對「環境行為」有正向影響力,表示從事環境行為的行為意向越高,在親子旅遊時越會去執行負責任的環境行為。4.本研究結果提供教育者、親子旅遊者、環境保護單位及後續研究之參考。 This study aims to investigate current situation and the differences of parent-child environmental behaviors in parent-child tourism through planned behavior theory. It also aims to explore the influences of parent-child demographic background, environmental attitude, subjective norms and conscious behavior control on behavior intention as well as the influence of behavioral intention on environmental behavior. It is hoped that this study will help create a better leisure environment. The participants of this study are parents and children who have participated in parent-child tourism. This study is a quantitative research and uses survey techniques to collect relevant data. The results are as following. As to parents, there are significant differences in environmental behavior and subjective norms between parents at different ages and occupations. Then, there are significant differences in conscious behavior control between the daily average costs of travel. As to children, there are significant differences in environmental attitudes between different travel frequency and having their mother graduated from graduate school. As to parents and children, conscious behavior control and environmental attitude that beyond graduate school all reached significant levels on behavioral intentions.Last but not least, behavioral intentions also have positive influences on environmental behaviors.The results of this study were provided for educators parent-child tourists, environmental protection-related units and further researchers.
