退休前的腐败被称作 59岁现象。其主体之动机是为了保障退休以后的生活。腐败时机的选择是一个跨期选择的问题。由于追求腐败效益的最大化，因此腐败活动集中在退休之前。有效地预防这一现象的发生，除了大力加强思想政治工作外，还要从加大惩处力度、加快制度创新、缩小退休前后生活水平的反差度、降低未来经济生活的不确定性等方面入手。 Pre-retirement corruption is called the 59-year-old phenomenon. The motivation of its main body is to protect the life after retirement. The timing of corruption is a matter of intertemporal choice. Due to the pursuit of maximizing the benefits of corruption, corruption is concentrated before retirement. To effectively prevent this from happening, besides vigorously strengthening ideological and political work, we should also start with intensifying penalties, speeding up system innovation, narrowing the contrast of living standards before and after retirement, and reducing the uncertainty of the future economic life.
