隨著全球人口結構改變，老年化已是社會普遍現象。以前將時間與金錢投注於家庭的老年人，隨著孩子們的獨立，可支配的金錢與時間漸漸增加，其旅遊消費潛力實不容忽視。本研究以參加亞洲地區最盛行之團體套裝旅遊年齡50歲以上旅客為研究對象，探討老年旅客參加團體旅遊之旅遊行為決策影響力。研究結果顯示決策影響力未隨著老年人年齡增加而減小；男性旅客決策影響力顯著大於女性旅客；個人月所得高之老年人決策影響力顯著大於低所得者；決策影響力會因老年旅客同行人數增加而減少；老年旅客對目的地愈熟悉，其決策影響力漸強，但未達顯著；老年旅客自己或配偶支付團費者時，決策影響力較大。

Along with the development of the global economy, our society has become older and more affluent. Seniors have generally made their financial and time investments in home and family, have become free from their children's dependency, and possess a relatively large share of all discretionary dollars. Thus, the key issue of this research is to focus on the senior tourist's decision-making for GPT. A total of 293 senior tourists from Taiwan, 50 years of age or older, on the GPTs were surveyed and asked to indicate the amount of influence each family member and others had. Analysis of variance (ANOVA) was used to test whether there were significant differences in perceptions regarding the influence of family members and others according to age, gender, income, travel party, who provide the tour expenses, and times of visiting the destination in separate and entire decision-making stages.
