本研究以計劃行為理論為基礎將其延伸,加入目的地意象及利他主義來探討遊客對於生態旅遊之行為意圖。透過實體問卷的施測,有效樣本270份,並以結構方程模式驗證研究假設。 從過去的研究讓我們?解生態?遊是重視環境教育與保育觀?、尊重當地文化、促進當地發展,並強調環境永續經營的觀?,其中,眾多研究顯示遊客對於目的地意象影響著遊客旅遊意願及重遊意願,但少有文獻探討其和生態旅遊間的關係;而對於環境關心與保育除了符合生態旅遊的內涵外,同時也符合利他主義的精神。故本研究著重於利他主義與目的地意象對遊客選擇生態?遊之影響。 研究結果顯示,利他主義會正向影響主觀規範;利他主義會正向影響行為意圖;利他主義會正向影響態度;目的地意象會正向影響主觀規範;目的地意象會正向影響態度;目的地意象會正向影響行為意圖;目的地意象會正向影響知覺行為控制;主觀規範會正向影響行為意圖;態度會正向影響行為意圖;知覺行為控制會正向影響行為意圖。 The study incorporates destination image and altruism with TPB model to investigate travelers’ behavior intention.
