Most leisure travel is motivated by interactions within one's social network, which influence the choice of activities undertaken in the city. In this paper, we employ a structural regression model to distinguish between the direct effect of social relations on leisure travel—measured as venue variety and activity space—and a complementary effect through the knowledge of the urban environment. The model was applied to a survey conducted in Zurich, Switzerland. The results demonstrate that individuals with stronger social relations are more aware of the activities that can be performed in the city. Furthermore, social relations serve as a strong explanatory variable for leisure activity space and venue variety, whereas the knowledge of the urban environment only influences venue variety. Accessibility also plays a significant role; higher accessibility reduces leisure activity space while increasing venue variety.

探索社会关系和城市环境知识对休闲旅游的影响

大多数休闲旅行都是由社交网络内的互动驱动的，这会影响在城市中进行的活动的选择。在本文中，我们采用结构回归模型来区分社会关系对休闲旅游的直接影响（以场地多样性和活动空间来衡量）和通过城市环境知识产生的补充效应。该模型应用于在瑞士苏黎世进行的一项调查。结果表明，社会关系较强的个人更了解可以在城市进行的活动。此外，社会关系是休闲活动空间和场地多样性的强解释变量，而对城市环境的了解仅影响场地多样性。可达性也发挥着重要作用；更高的可达性减少了休闲活动空间，同时增加了场地多样性。
