稀缺是指个体拥有的资源少于需求的状态，包括时间、金钱等。而冒险行为则是指参与有概率产生不良后果的行为。前人对于稀缺与冒险行为的关系没有得到统一的结论，并且为两者建立了诸多模型，如生命史、稀缺心态以及定向调节等。一些研究者将冒险行为分为所有结果立即结算和收益立即结算、风险滞后出现两种，但在稀缺与冒险行为的领域中缺乏同时测量两种冒险行为的研究，仅测量其中之一可能会导致忽略另一种冒险行为的效应。因此本研究通过设计一个捕鱼实验，在启动大学生被试时间稀缺以及金钱稀缺后，同时测量被试两种风险出现时间不同的冒险行为，来探究时间和金钱稀缺是否对风险滞后或立即呈现的冒险行为有不同的影响。结果表明，时间稀缺显著减少了被试的风险立即呈现的冒险行为，金钱稀缺对风险立即呈现的冒险行为有抑制倾向。未来研究可以针对稀缺进行更深的发掘。

Scarcity refers to the state that an individual has less resources than demand, including time, money and so on. Risk taking behavior refers to the behavior that has the probability of adverse consequences. Predecessors have not reached a unified conclusion on the relationship between scarcity and risk-taking behavior, and have established many models for them, such as life history, scarcity mentality and directional regulation. Some researchers divide risk-taking behavior into immediate settlement of all results and immediate settlement of benefits, and risk lag. However, there is a lack of research on measuring two kinds of risk-taking behavior at the same time in the field of scarcity and risk-taking behavior. Measuring only one of them may lead to ignoring the effect of the other kind of risk-taking behavior. Therefore, this study designs a fishing experiment, after starting the time scarcity and money scarcity of college students, and measures the risk-taking behavior of the subjects with different risk occurrence time at the same time, so as to explore whether the time and money scarcity have different effects on the risk lag or immediate risk-taking behavior. The results show that time scarcity significantly reduces the subjects' risk-taking behavior immediately, and money scarcity tends to inhibit the risk-taking behavior immediately. Future research can further explore scarcity.
