Altruism in tourism: Social Exchange Theory vs Altruistic Surplus Phenomenon in host volunteering
通过对希腊韦里亚两个旅游志愿协会21名成员的探索性研究，发现互惠利他是参与动机之一，且利他剩余现象比社会交换理论更能解释其社会行为。
Taking into consideration the scarcity of research on volunteering and altruistic behavior of host communities, this exploratory study examines altruism in tourism from the viewpoint of members of voluntary tourism associations. A literature review reveals two general types of altruism, i.e. reciprocal and true, as well as two theoretical constructs, namely Social Exchange Theory (SET) and Altruistic Surplus Phenomenon (ASP). By taking a sample of 21 members from two voluntary tourism associations located in the municipality of Veria, Northern Greece, this study confirms that reciprocal altruism is one of several motives for participating in voluntary tourism associations. Additionally, it is shown that ASP is more adequate than SET to interpret the study groups’ social behavior.
