信息时代的巨大变革和社会经济的快速发展使人们的生活变得更加便捷，但同时也暴露了一些通过网络技术手段违法谋取暴利的漏洞，提供了更多投机取巧获得非法利益的机会，成为了贪婪思想的温床。贪婪会带来很多消极影响。贪婪的人会不择手段获取资源和利益，影响社会治安和规范，导致一系列的社会问题。正念作为当下比较流行的减压方法，它对于个体的生活满意度、情绪等都会有正向的影响。正念指的是集中注意力，有特定目的地关注当下、关注自身。它提醒我们关注于自己所拥有的东西，而不是对超出自己需要的部分保持渴望，这与贪婪的本质恰好相反。由此本研究推测，正念对贪婪会有负向的预测作用。同时，有多个研究已经证实了正念能够提升自我控制能力，而自我控制又能够减弱不诚实等不道德的行为，因此本研究探讨了自我控制在正念与贪婪的关系中的中介作用。 本研究通过两个子研究检验以上问题。研究一以问卷测量的方式，以成年群体（N = 187）为对象验证正念和贪婪之间的关系，并探索自我控制的中介作用；研究二通过实验室实验，操纵被试的正念水平，考察正念和贪婪之间的因果关系及其中介机制。研究主要获得以下发现： （1）正念对贪婪有稳定的抑制作用，即正念水平越高的人，贪婪越低。 （2）在正念对贪婪的负向预测作用中，自我控制的中介作用在测量模型中得到支持，而在实验室研究模型中没有得到支持。

The great changes in the information age and the rapid development of social economy make people's life more convenient, but at the same time, it also exposes some loopholes of illegal profiteering through network technology, providing more opportunities for opportunistic gain of illegal interests and becoming a hotbed of greed. Greed has many negative effects. Greedy people will stop at nothing to obtain resources and interests, affecting social security and norms, resulting in a series of social problems. As a popular method to relieve stress, mindfulness has a positive impact on life satisfaction and emotion. Mindfulness is focused attention, focused on the present with a specific purpose, focused on the self. It reminds us to focus on what we have instead of wanting more than we need, which is contrary to the nature of greed. Therefore, this study speculates that mindfulness has a negative predictive effect on greed. At the same time, several studies have confirmed that mindfulness can improve self-control, and self-control can reduce dishonest and other immoral behaviors. Therefore, this study explores the mediating role of self-control in the relationship between mindfulness and greed. This study examined the above questions through two substudies. The first study examined the relationship between mindfulness and greed in an adult population (N = 187) using questionnaires and explored the mediating role of self-control. Study 2 manipulated participants' levels of mindfulness through laboratory experiments to investigate the causal relationship between mindfulness and greed and its mediating mechanism. The main findings are as follows: (1) mindfulness has a stable inhibitory effect on greed, that is, the higher the level of mindfulness, the lower the greed. (2) in the negative prediction effect of mindfulness on greed, the mediating effect of self-control was supported in the measurement model, but not in the laboratory research model
