本文使用CHNS1989～2009年数据,系统考察了影响中国城镇居民相对收入流动的各种主要因素的作用。通过运用有序Logit模型,本文发现:(1)个人期初所在的收入阶层越低,越有可能向上流动,表明中国城镇居民收入阶层流动具有缩小差距的属性。(2)期初收入阶层上述效应随时间有增强趋势,但2000年以后逆转,个人期初收入阶层越低,越难向上流动,收入阶层呈固化态势。(3)家庭规模越小、财产越多,所在单位如果是国有企业,从事的如果是管理性的工作,户籍所在地如果属于东部,越有利于实现个人收入阶层的向上流动。(4)由于所在单位如果是国有企业对越底层的人们作用越大,因而它有助于缩小收入差距;而家庭财产越多、从事的如果是管理性的工作、户籍所在地如果属于东部则可能是导致收入差距扩大的原因。
This article uses the CHNS data from 1989 to 2009 and systematically examines the role of various major factors that affect the relative income flows of Chinese urban residents. By using an orderly Logit model, the dissertation finds that: (1) The lower the income class at the beginning of an individual’s age, the more likely it is to move upward, indicating that there is a property that narrows the gap between income flows of urban residents in China. (2) Income Earlier at the Beginning The above-mentioned effects tended to increase over time. However, after 2000, the income earning stratagem of the individual at the beginning of the year is more difficult to move upward and the income stratum is in a solidified position. (3) The smaller the family and the more property, the unit where the unit is located is a state-owned enterprise. If the place where the household registration belongs to the east is more conducive to the upward mobility of the individual income class. (4) Since the unit where the unit is located is the greater the effect on the people on the lower floor, it helps to narrow the income gap. The more family property is, the more engaged management is, and the place of residence may be east if it is located This is the reason why the income gap has widened.
