本研究通过相关和因果设计探讨了居住流动性对个体在跨期决策中的远期选项的主观价值的影响，同时还在前人研究的基础上考察了未来自我连续性的调节作用以及焦虑水平的中介作用。研究一为线上的相关研究，结果发现：未来自我连续性对特质焦虑有显著的预测作用，居住流动性和未来自我连续性的交互项对特质焦虑的预测作用边缘显著；特质焦虑对远期选项的主观价值的预测作用边缘显著。研究二为线上的实验研究，操控了居住流动性，结果表明：居住流动性分组对状态焦虑的主效应显著，高居住流动性组的状态焦虑显著高于低居住流动性组；而以远期选项的主观价值为因变量做回归分析，居住流动性分组、未来自我连续性分组以及二者的交互项对因变量均无预测作用，以状态焦虑为因变量做回归分析，居住流动性分组、未来自我连续性分组以及二者的交互项对状态焦虑均无预测作用，与假设预期不符。当前研究探讨了居住流动性对跨期决策的作用机制，首次验证了未来自我连续性的调节效应，关注了焦虑的中介作用，丰富了领域内的研究证据。

This research which contains a correlation study and a causal study, explored the effect of residential mobility on the subjective value of long-term option when people are going through intertemporal decision-making. At the same time, it examines the moderating effect of future self-continuity and the mediating effect of trait anxiety and state anxiety.

Study 1 is an online correlation study. In study 1, results showed that future self-continuity significantly affected trait anxiety. The predictive effect of the interaction term of residence mobility and future self-continuity on trait anxiety wasmarginally significant. The predictive effect of trait anxiety on subjective value of long-term option was also marginally significant.

Study 2 is an online experiment which manipulate residential mobility. In study 2, results of variance analysis showed that the main effect of residential mobility was significant. Specifically, the state anxiety of the high mobility group was significantly higher than that of the low mobility group. However, in linear-regression analysis, neither residential mobility, future self-continuity or the interaction term of them could significantly predict subjective value of long-term option, which was not consistent with hypothesis.

the current study explored the mechanism of residential mobility on intertemporal decision making, verified the moderation effect of future self-continuity and paid attention to the mediating effect of anxiety, which enriched research evidence.
