摘　　要：基于回归方程的收入差距分解发现,1988年、1995年和2002年,行业间收入不平等对中国城镇居民收入差距的贡献越来越大,而且这主要是由一些收入迅速提高的垄断行业造成的。同时,区位、教育、所有制和职业类型以及是否有第二职业对收入差距的贡献也在提高,是否完全就业和年龄对收入差距的贡献有明显下降。因此,缩小中国城镇收入差距,亟需打破劳动力市场进入壁垒和产品市场行业垄断。此外,减轻地区间的劳动力流动障碍、普遍提高劳动者的受教育水平等措施,也将是未来政府缩小城镇收入差距的重要政策着力点。A regression-based decomposition of income disparity shows that in the years 1988,1995 and 2002 inter-industry inequality made a rising contribution to income disparity in urban China and that most of this disparity was caused by monopoly industries' soaring earnings.At the same time,locality,education,property ownership,occupation and the presence of a second occupation contributed increasingly to income disparity,while the contribution of age and being fully employed fell significantly.Therefore,there is a pressing need to break down barriers to labor market access and industry monopolies in the product market in order to narrow the urban income gap.In addition,measures such as removing obstacles to labor migration across regions and raising the educational level of workers everywhere are recommended policy interventions for future government action to reduce the income gap.
