当下的中国正经历着急速的流动热潮，而流动也正在推动社会的进步与发展。从历史的颠沛流离中走出，如今流动已成了机遇与希望的代名词。不过，社会生态心理学大量研究发现，高居住流动性所带来的多变、不稳定的环境会导致诸多负面行为，并降低个体的幸福感。本研究认为，以往居住流动性的研究在强调客观环境的同时忽略了人对环境的把控和感知，特别是流动自主性的影响。基于自我决定论，本研究提出主动流动(vs.被动流动)的概念，将在流动动机或流动过程中体现出自主性的居住流动称为主动流动，并认为主动流动将降低个体的环境威胁感知，从而使流动对于主观幸福感的伤害得到缓解甚至逆转。通过两个平行研究检验此假设。研究1聚焦流动过程中的自主性，对291名社会人士进行问卷调查，考察了其与环境威胁感知及主观幸福感的关系；研究2聚焦流动动机，对43名大学生被试启动主动流动或被动流动思维定势，检验其与主观幸福感的因果关系及环境威胁感知的潜在中介作用。两个研究一致地发现，流动自主性(即主动流动)能够正向预测个体的主观幸福感，而较低的环境威胁感知在其中起到中介作用。

Nowadays, China is undergoing rapid population movements boom, and population itself is the force of process and development throughout our society. Nevertheless, extensive studies of socioecological psychology have found the ever-changing and unstable environment which comes with high residential mobility lead to numerous negative consequences, including low subjective well-being. This study suggested previous studies stressed physical environment but neglected ones’ control and perception over environment, especially for move autonomy. Based on self-determination theory, this study proposed the concept of active move (vs. passive move). Active move refers to movement during which the autonomy is shown through move motivation or move process, and it will weaken the environment threat perception (ETP), eventually buffer residential mobility’s negative effect on well-being. Two parallel study were designed to test the hypothesis. Study 1 focused on autonomy during movement and had 291 participants completed questionnaires to explore its relationship with ETP and subjective well-being. Study 2 focused on move motivation and primed active move (or passive move) mindset on 43 college students to verify its causality with subjective well-being and potential mediator of ETP. Results consistently showed that move autonomy (or active move) positively predicted subjective well-being, with the mediation of lower ETP.
