中国持续扩大的收入差距为什么没有引发大的社会动荡?本文基于社会流动的视角,利用中国综合社会调查(CGSS)数据进行了探讨。实证研究结果表明,社会流动对公众的收入分配公平感有显著的影响。研究结论表明,在社会转型中,虽然出现了快速的贫富差距扩大,但是大规模的社会流动使人们对未来抱有较高的心理预期,从而弱化了公众的收入分配不公平感。这一结论的重要启示是,在收入分配差距扩大暂时难以扭转的情况下,保持通畅的社会流动,对于社会稳定有着重要的现实意义。 Why did China’s ever-widening income gap lead to no major social unrest? This article explores the use of CGSS data from a social mobility perspective. The empirical results show that social mobility has a significant impact on the public’s sense of fairness in income distribution. The conclusion of the study shows that in the process of social transformation, despite the rapid gap between the rich and the poor, large-scale social mobility makes people have higher psychological expectations for the future and weakens the public’s unfair distribution of income. The important enlightenment from this conclusion is that maintaining the unobstructed social mobility is of great practical significance for social stability in the event that the income distribution gap is temporarily unmanageable.
